**Notes:**
1988 MUTCD:  Part 6 Title, Standards and Guides for Traffic Controls for Street and Highway Construction, Maintenance, Utility, and Incident Management Operations.
Final Rule:  Part 6 Title, Temporary Traffic Control.

Explanation:	The FHWA has changed the title of Part 6 from Standards and Guides for Traffic Controls for Street and Highway Construction, Maintenance, Utility, and Incident Management Operations to “Temporary Traffic Control.”  This title was recommended by the NCUTCD and it  better explains the contents of this part.

## Temporary Traffic Control

- In *Section 6A, para. 2*, ...temporary traffic control must provide for the safety of workers, road users, etc ...it must provide...efficient completion...

*In Section 6A.01, para.* 3*,*..4th sent. “At the same , it provides efficient completion... “

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6A, para.graph 2,  2nd and 3rd  sentences  read as follows: “Effective temporary traffic control  must provide for the safety of workers, road users, and pedestrains.   At the same time, it must  provide for the efficient completion of whatever activity suspended normal use of roadway.”
Final Rule: Support:   In Section 6A.01, para.graph 3,  the above 2nd sentence was deleted and the 4th sentence read as follows: “At the same time, it  provides for the efficient completion of whatever activity interrupted normal use of the roadway. “

Explanation:	In Section 6A.01, para.graph 3, the FHWA has deleted the second sentence.  Also, the word “must” has been deleted from the fourth sentence.  This deletion was made because temporary traffic control does not guarantee the safety or efficient completion of a work activity.

## GENERAL

*In Section 6B.7, 2**nd** & 3**rd* *sent*., “For these.... adequate legislative authority for the implementation enforcement... speed zoning, and incident management.”

*In section 6A.01, Standard para. 2**nd** & 3**rd** **–”T*here shall be adequate* *statutory  authority for the  implementation ...Such statues shall flexibility...traffic control zone.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Mandatory Condition:  In Section 6B.7, 2nd & 3rd sentences, “For these operations there must  be adequate legislative authority for the implementation and enforcement of needed traffic regulations, parking controls, speed zoning, and incident management.  Such statues must provide sufficient flexibility in the application of traffic control to meet the needs of changing conditions in work areas.
Final Rule:  Standard:  In Section 6A.01, 7th para., 2nd & 3rd sentences “ There shall be adequate statutory authority for the implementation and enforcement of needed road users regulations, parking controls, speed zoning, and incident management.  Such statutes shall provide sufficient flexibility in the application of temporary traffic control meet the needs of changing conditions in the temporary traffic control zone.

Explanation:  The FHWA has moved a portion of the above Standard from the end of Chapter 6B Fundamental Principles to Chapter 6A.01 General because it applies to all Chapters of Part 6. 

## Objective of Traffic Control

*Section 6A, para. 6, 2nd sent.* “Simultaneously, the control selected must permit efficient maint./constr.of rdwys & roadways...”

*Section 6B.01, 4**th** Support para., 2nd* *sent.* “A concurrent objective of the traffic control is the efficient const. & maint. of the roadway.”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6A.01, para.graph  6, 2nd sentence,  “ Simultaneously, the control selected must permit  efficient maintenance/construction of roadways and roadway appurtenances.”       
Final Rule:   Support:    In Section 6A.01, 4th Support para.graph, 2nd sentence,  “A concurrent of objective of the traffic control is the efficient construction and maintenance of the roadway.” 

Explanation:  This change has been made to clarified  the objective of proper traffic control.

## Flagging Procedures

*Section 6B. 3c, *Flagging procedures, when used, can provide guidance to drivers . . .

*Section 6B.01, 4th , * *GUIDANCE para. Subpara. C:* “Flagging procedures when used, should provide positive guidance . . .

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6B.3c “Flagging procedures, when used, can provide guidance to drivers traversing the temporary control area.”

Final Rule:	 GUIDANCE:  In Section, 6B.01, 4th Guidance para., subpara. C “ Flagging procedures when  used, should provide positive guidance to drivers traversing the temporary traffic control area.”

Explanations:  This change clarifies the intent to  provide positive guidance to drivers to safely travel through temporary traffic control area.

## Traffic Control Devices

*In Section 6B.4a, 2nd sent., *The most important duty of these... individual is to ensure... all traffic ... effective in providing safe  conditions . . . and workers.

*Section 6B.01. 5**th** Guidance para. , Subpara. A , 2nd sent.* “The most important duty ... individual should be ... consistent with traffic ... safe conditions... and workers.”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6B.4a, 2nd sentence “ The most important duty of these individuals is to ensure that all traffic control devices measures implemented on the project are necessary, conform to the traffic control plan, and are effective in providing safe conditions for motorists, pedestrains, and workers.”
Final Rule:	  GUIDANCE:  In Section, 6B.01. 5th Guidance para. Subpara. A,  2nd sentence “ The most important duty of these individuals should be to ensure that all traffic control elements of the project are consistent with the traffic control plan and are effective in providing safe conditions for motorists, pedestrains, and workers.” 

Explanations:  This change will help ensure that proper traffic control measures are being carried out.

## Traffic Control Devices

*Section  6B.4e, 1st sent. “ *All traffic control devices* *_should_ be removed when no longer needed.”

*Section 6B.01, 2nd Standard para.*,  “All temporary traffic control devices _shall_ be removed... when they are no longer needed.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  “In Section 6B.4e, 1st sentence “All traffic control devices should be removed when no longer needed.”

Final Rule:   STANDARD:  In Section 6B.01, 2nd Standard para.graph, “All traffic control  devices shall be removed as soon as practical when no longer needed.”

Explanation:  This change will emphasize  that  all traffic control devices are removed no longer required.

##  Public Relations

*Section 6B.8, 1st sent.,                     “** *Maintaining good public relations is necessary.*” *

*Section 6.B.01, 8th Guidance para., “*Good* *public relations should be maintained by applying the following principles...”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:   Mandatory Condition:    In Section, 6B.8, 1st sentence, “ Maintaining good public relations is necessary.”
Final Rule:   GUIDANCE:  In Section  6B.01, 8th Guidance para., “ Good public relations should be maintained by applying the following principles: 
The cooperation of the various news media in publicizing the existence of and reasons for temporary traffic control zones should be sought as news releases can assist in keeping the road users well informed.
 The needs of abutting property owners, residents and business should assessed and appropriate accommodations made.
  The needs of emergency service providers (police, fire, and medical) should be assessed and appropriate coordination and accommodations made.
  The needs of railroad and transit should be assessed and appropriate coordination and accommodations made.” 

Explanation:    This sentence has been revised from a mandatory statement to a Guidance.  

## Traffic Control Plans for Transit 

*Section 6C-6, “*Provision for effective continuity of transit service needs to be  ... into Traffic Control Planning...”

*Section 6C.01, 5**th** Guidance para., *“Provisions for effective continuity of transit services should be ...into Traffic Control Plan...”* *

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Mandatory Condition:  In Section, 6C-6, “ Provision for effective continuity of transmit service needs to be incorporated into temporary traffic control planning process. Oftentimes, public transmit buses cannot efficiently be detoured in the same manner as other vehicles (particularly for short-term maintenance projects).  On transit routes, the Traffic Control Plans shall provide for features such as temporary bus stops, pull-outs, and waiting areas for transit patrons.”
Final Rule:   GUIDANCE:  In Section, 6C.01, 5th Guidance para.graph, “Provisions for effective continuity of transit service should be incorporated into the temporary traffic control planning process.  Oftentimes, public transmit buses cannot efficiently be detoured in the same manner as other vehicles (particularly for short-term maintenance projects).  The TCP should provide for features such as temporary bus stops, pull-outs, and satisfactory waiting area for transmit patrons, if applicable.  (See Section 10A.05 for additional light rail transmit issues to consider for temporary traffic control).” 

Explanations:   This change concerning traffic control plans for transit is from a    mandatory shall statement to recommended GUIDANCE.

## Temporary Traffic Control Plans

- Not in the MUTCD.

-  *In Section 6C.01, 6**th** & 7**th** Guidance para.* “Reduced speed limits should be used only in the specific portion of the temporary traffic control  zone where ...”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Not in the MUTCD.
Final Rule:  GUIDANCE:  In Section 6C.01, 6th & 7th  Guidance  para.graph, “ Reduced speed limits should be used only in the specific portion of the temporary traffic control zone where conditions or restrictive features are present.  However, freguent changes in the speed limit should be avoided.  A temporary traffic control plan should be designed so that vehicles can safely travel through the temporary traffic control zone with a speed limit reduction of no more than 16 km/h (10 mph).
  A reduction of more than 16 km/h (10 mph) in the speed limit should be used only when required by restrictive features in the temporary traffic control zone.  Where restrictive features justify a speed reduction of more than 16 km/h (10 mph), additional driver notification should be provided.  The speed limit should be stepped down in the advance of the location requiring the lowest speed, and additional temporary traffic control warning should be used. 
Explanation:  This change will have no economic impact on State and local highway agencies.  However, roadway safety and efficiently should increase because research has shown that speed reductions should be no more than a 10 mph increment.

## Temporary Traffic Control  Zones

- Not in the MUTCD
*Section 6C-2, para. 1, 1st sent.,  Definition -“*The temporary traffic control zone includes .... between first advance warning sign ... last traffic control device ...”

- New Section,  *Sect. 6C.02,“*Temporary Traffic Control Zone”
- added*:  Section*** **6C.02,** **para. 1 - Definition, “A**   **temporary traffic control  zone is an area of highway officials.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Not in MUTCD.  However, in Section 6C-2, para.graph  1, Definition- “The temporary traffic control zone includes the entire section of roadway between the first advance warning sign through the last traffic control device, where traffic returns to its normal path and conditions.”
Final Rule:   Support:  In Section 6C.02, new section, “TTTCZ” was added.  Also added was para.graphs 1,2 & 3  reads as followed:  “ A temporary traffic control zone is an area of a highway where road road user conditions are changed because of a work zone or an incident though the use of temporary traffic control devices, police, or other authorized officials.  A work zone is an area of a highway with construction, maintenance, or utility work activities.  A work zone is typically marked by signs, channelizing devices, barriers, pavement markings, and/or work vehicles. It extends from the first warning sign or rotating/strobe lights on a vehicle to the END ROAD WORK sign or the last temporary traffic control device.  An incident area is an area of a highway where temporary traffic controls are imposed by authorized officials in response to a road user incident, natural disaster, or special event. 
Explanations:  A new Section 6C.02 Temporary Traffic Control Zones, has been added to the MUTCD to better define temporary control zones.  It contains only general information concerned with the temporary traffic control zones.  Due to no uniform definition of a work zone, work crash data collection was not uniformed.  Therefore, FHWA formed a task force with representatives from Association  General Contractors Association , American Roads and Transportation Builders Association ,  National Associated of County Engineers, American National  Standard Organization , FHWA, AASHTO,  and NHSTA  to address the issue of establishing a standard work zone definition..  The above definition is the result of the FHWA Work Zone Task Force.  In the NPA the above text was included as part of the Section 6C-2 components of Temporary Traffic control Zones.  This change is not adding any new requirements for the State or local jurisdictions.      

## Components of Temporary Traffic Zones Control 

*In Section 6C-2 -*_ _Examples of a work zone  area & an incident area was not in the  MUTCD_ _

- Reference in the NPA as Section 6C.2-4 components of TTZC examples of  WZ & incident area removed from this section 6C.2 and relocated to Chapter 6G.

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6C-2, there were not examples of a work zone area and an incident area.  
Final Rule: In Section 6G, the are examples of work zone areas and incident areas.  These examples have removed from Section 6C.2 of the NPA to this Section 6G what discusses the the types of temporary traffic control activities.  We received comments suggesting that we move the examples from Section 6C.2 to Section 6G for clarification of the text and the FHWA greed with the comments.  

## Placement of Warning Signs

*In Section 6C-2(a), 2**nd** sentence, *“On freeways and expressways , where  driver speed is * *generally...higher range (45 mph or more)... 500 ft to 1/2 mile...”

*In Section 6C..04, 1**st** Guidance para. “*Typical distances for placement of advance warning signs ... freeway ...800 m (1/2 mile) or more.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Permissive Condition:   In Section 6C-2a, 2nd sentence “ On freeways and expressways, where driver speed is generally in the higher range (45 mph or more), signs may be placed from  500 feet to 1/2 mile or more before the temporary traffic control zone. ”
FINAL RULE:  GUIDANCE:  In Section 6C.04, 1st Guidance para.graph, “ Typical distances for placement of warning signs on expressways and freeways should be longer because drivers are conditioned to uninterrupted flow.  Therefore, the advance warning signs should extend on these facilities as far as 800 m (0.5 mile) or more.”  

Explanation:  This change will provide additional guidance on the placement of advance warning signs on freeways and expressways.

## Advance Warning Area Sign Spacing 

*Section 6C-2a(1),* Warning sign spacing in advance Urban range from 1 to 4 times speed ...
*Section 6C-2a(2), *Rural warning spacing is 8 to 12 times speed ...

*Section 6C.04 2**nd** Guidance  para., *“On urban streets, the  effective placement of ...warning signs in  (feet) should range ...”
*Section 6C.04. 3**rd** para. 3*, “Since rural highways ... the effective placement of the first...”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Mandatory Condition:   In  Section 6C-2a(1),  “Urban- Warning sign spacing in advance of the transition area normally range from 4 to 8 times speed (mph) in feet, with the high end of the range being used when speeds are relatively high. 
 Rural- Rural roadways are characterized  by higher speeds.  Spacing for placement of warning signs is substantially longer-from 8 to 12 times the speed (mph) in feet.”
FINAL RULE:  GUIDANCE:  In  Section 6C.04, 2nd Guidance para.graph, “On urban streets, the effective placement of the first warning sign in meters (feet) should range from 0.75 to 1.5 times the speed limit in km/h (4 to 8 times the speed limit in mph), with the high end of the range being used when speeds are relatively high.”
In Section 6C.04, 3rd para.graph, “Since rural highway are normally characterized by higher speeds, the effective placement of the first warning sign in meters (feet) should be substantially longer- from 1.5 to 2.25 times the speed limit in km/h (8 to 12 times the speed limit in mph).” 
Explanation:   These changes will provide clearer guidance on  placement of warning signs.

## Longitudinal Buffer Space

*In Section 6C-2c(3a), 2nd para., *“The longitudinal space, as depicted in fig.VI-2, should ...”*  *

*In Section 6C.06, 4**th** Option para. , *“The longitudinal buffer space maybe used ...Figure 6C-2.”

**Notes:**
1988 MUTCD:   In Section 6C-2c(3a), “The longitudinal buffer space, as depicted in Figure VI-2, should be used where a closed lane separa.tes opposing traffic flows.”
Final Rule:  Option:  In Section 6C.06, 4th Option para.graph “Longitudinal Buffer Space:  The longitudinal buffer space may also used to separa.te opposing traffic flows that utilize portions of the same traffic lane, as depicted in Figure 6-2.”  

Explanation:   This change has been made because buffer spaces are optional.

## Longitudinal Buffer Space (Figure 6C-2)

**Notes:**
1988 MUTCD:   In Section 6C-2c(3a), “The longitudinal buffer space, as depicted in Figure VI-2, should be used where a closed lane separa.tes opposing traffic flows.”
Final Rule:  Option:  In Section 6C.06, 4th Option para.graph “Longitudinal Buffer Space:  The longitudinal buffer space may also used to separa.te opposing traffic flows that utilize portions of the same traffic lane, as depicted in Figure 6-2.”  

Explanation:   This change has been made because buffer spaces are optional.

## Table 6E-1, Distance of Flagger Station - Work  Area

*In Section 6C-1c(a)- *Table VI-1, “Guidelines for the length of... and *in the NPA, Section 6C.5,* Table 6-1, Guidelines for the length of minimum advance working area”

*In Section 6E.05,* Table 6E-1, Distance of Flagger Station in Advance of the work Space has been moved from Section 6C.

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6C-1c(a), Table VI-1, Guidelines for length of longitudinal buffer space and in Section 6C5, Table 6-1, Guidelines for length of minimum advance working area.
Final Rule:  Support:   In Section 6E.05, “Guidelines for determining the distance of the flagger station in advance of the work space are shown in Table 6E-1.”

Explanation:  In Section 6C.06 Activity area (referenced in the NPA as Section 6C.5), Table 6-1,” Guidelines for Length of Minimum Advance Working Area,” was incorrectly titled and located in the NPA.  The FHWA has renumbered the table as Table 6E-1, and has moved the table to Section 6E.05 Flagger Stations, and re-titled it “Distance of Flagger Station in Advance of Work Space.”  This table provides information on the distance a flagger should be in advance of the work based on the speed of approaching traffic.  The information in the table has nothing to do with Activity areas and lengths of minimum advance work areas. 

## Table 6E-1,Distance of Flagger Station - Work  Area

**Notes:**
1988 MUTCD:  In Section 6C-1c(a), Table VI-1, Guidelines for length of longitudinal buffer space and in Section 6C5, Table 6-1, Guidelines for length of minimum advance working area.
Final Rule:  Support:   In Section 6E.05, “Guidelines for determining the distance of the flagger station in advance of the work space are shown in Table 6E-1.”

Explanation:  In Section 6C.06 Activity area (referenced in the NPA as Section 6C.5), Table 6-1,” Guidelines for Length of Minimum Advance Working Area,” was incorrectly titled and located in the NPA.  The FHWA has renumbered the table as Table 6E-1, and has moved the table to Section 6E.05 Flagger Stations, and re-titled it “Distance of Flagger Station in Advance of Work Space.”  This table provides information on the distance a flagger should be in advance of the work based on the speed of approaching traffic.  The information in the table has nothing to do with Activity areas and lengths of minimum advance work areas. 

## Termination Area

- Definition of termination area was not in the MUTCD_ _
*In Section  6C-2(d), 2**nd** sent.* .. The END ROAD WORK sign should normally not be used...

*In Section 6C.07, 1**st** Support para.*-The termination area is used to return road users to their normal path..
- Guidance statement dealing with END ROAD WORK sign...
-    Moved to Section G20-2.

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6C-3, there was no definition of a termination area.
(2)  In Section 6C-2(d), 2nd sentence, “For example, the END ROAD Work signs should normally not be used if other temporary traffic control zones begin within a mile of the end of quarter-mile within urban areas.”   
Final Rule:  Support:  In Section 6C.07, 1 st para.graph, “The termination area is used to return users to their normal path.”  In the Federal register, comment 180 states the FHWA has changed the first support statement stated above to a Standard as the statement is a definition, and definition are by their nature STANDARDS.   This is an error and in a future rulemaking, we will changed the Support para.graph to a Standard para.graph. (2)  The Guidance statement “The END ROAD WORK (G20-2a) sign should be placed about 1500 m (500 ft) beyond the temporary traffic control zone.  (3)  Option statement has been added “An END ROAD WORK sign, a Speed Limit sign, or orther signs may be used to inform road users that they can resume normal operations.” 

Explanation:  (1)  Definitions are by their very nature Standards.  (2) The GUIDANCE statement dealing with END ROAD WORK signs has been moved to to Section 6F.49 END ROAD WORK sign because it most appropriately goes in the section that describes the sign and not in the section discussing termination area.  (3)  An Option statement was added to indicate the need for an END ROAD WORK, speed limit, or other sign to indicate to road users that they may resume normal operations.  These changes were made to be consistent throughout the MUTCD and to add guidance to optimize road user performance in temporary traffic control zones.           

## Taper Lengths

*In Section 6C-3, 1**st** para. , 7th sent.* “Types of taper length are presented in table VI-2.”
*In Section 6C-3, 1st para. , 8th sent.,*  “The max. space between devices.....”

*In section 6C.08, 1**st** Guidance para.,*  “The criteria for determining the taper lengths ... in Table 6C-2 and should....
*In Section 6C.08, 2**nd** Guidance para.*  “The maximum distance in meters (feet) ...

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:   In Section 6C-3, 1st para.graph, 7th sentence.   “ Types of taper lengths are presented in table VI-2.”  In Section 6C-3, 1st para.graph, 8th sentence.   The maximum space between devices in a taper normally approximately  the distance in feet of the speed in mph  (i.e. a 55 mph speed road shown  normally have devices spaced about 55 feet a part).”
Final Rule:  GUIDANCE:  In Section, 6C.08, 1st Guidance para.graph, “The criteria for determining the taper length (L) is shown in Table 6C-2 and should be the minimum used.”  In Section 6C.08, 2nd Guidance para.graph.  “The maximum distance in meters (feet) between devices in a taper should not exceed 0.2 times the speed limit in km\h (1.0 times the speed limit in mph).”   

Explanation:   This change will required a certain spacing between channelizing devices unless proper justification is given.  Also, the option for the one-half spacing is in response to recommendations contained in the Older Driver Highway Design Handbook.  Report No. FHWA-RD-99-045, available from FHWA Research & Technology Report Center. 

## Shifting Tapers

*In Section 6C-3(b),  2**nd** , sen., *“Approx. 1/2 L has been found to be adequate.

*In Section, 6C.08., 4**th** Guidance para. , *“ A shifting taper should have a length of approximately  1/2 L...”

**Notes:**
1988 MUTCD:  In Section 6C-3(b), 2nd sentence,  “Approximately one-half length has been found to be adequate.” 
Final Rule:   GUIDANCE:  In Section 6C.08, 4th Guidance para.graph, “ A shifting  taper should have a length of approximately one-half  L (see Table 6C-2).”

Explanation:   This change will require a certain length for shifting tapers unless proper  justification  is given.  This proposed change is in response to recommendations contained in the Older Driver Highway Design Handbook.

## Flagging Methods

*In Section 6C-5a,  3th sent*., “When good visibility & traffic control cannot be maintained by one flagger ... a flagger at each end ...* “*

*In Section 6C.11, Guidance para., 2nd sent. *...”When good visibility & traffic control cannot be maintained by one flagger ... a flagger at each end ...“

**Notes:**
1988 MUTCD:   Option:   In Section  6C-5a, para.graph  1, 3th sentence, “When good visibility and traffic control cannot be maintained by one flagger station, traffic may be controlled by a flagger at each end of the section.”
Final Rule:  GUIDANCE:   In section 6C.11, Guidance para.graph, 2nd sentence, “ When good visibility and traffic control cannot be maintained by one flagger station, traffic should be controlled by a flagger at each end of the section.”

Explanation:   This change recommends two flaggers in one-lane, two -way temporary traffic control zone.  

## Pedestrains Considerations

- Not in the MUTCD

*In Section 6D.01, 8 th Guidance para., 2**nd** sent.,* “ Staging or stopping of by work vehicles...”
*15**th** Guidance para., *“The highway agencies... regularly inspected...”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Not in the MUTCD. 
Final Rule:  GUIDANCE:  In Section 6D.01, 8th Guidance para.graph 2nd sentence, “Staging or stopping of work vehicles or equipment along the side of pedestrians paths should be avoided, since it encourages the movement of workers, equipment and materials across the pedestrian path.”
Section 6D.01, 15th Guidance para.graph “ The highway agency in charge of the temporary traffic control should regularly inspect the activity area so that effective pedestrian traffic control is maintained.”

Explanation:   These additions will provide additional guidance for and increase safety of pedestrians.   

## Pedestrain Considerations

*In Section 6D-1, para. 6, 1**st** sent.* “At work sites of  significant ... where falling debris is a concern... falling debris.”

*In Section 6D.01.  2**nd* *Option para.* “A canopied walkway  may be used ...”

1988 MUTCD:   In Section 6D-1, para. 6, 1st sentence,  “ At work sites of significant duration, especially in urban areas with pedestrain volume, and where falling debris is a concern (such as work on over structures), a canopied walkway is frequently needed to protect pedestrains from falling debris.”  
Final Rule:  Option:   In Section 6D.01, 2nd Option, “ A canopied walkway may be used to protect pedestrains from falling debris.”

Explanation:  In the existing MUTCD the intent of the sentence was to provide safety to pedestrains by providing a canopied walkway.  This change will provide an increased emphasis on pedestrain safety.

**Notes:**
1988 MUTCD:  Not in the current MUTCD.
Final Rule:  Option:    In Section 6D.02, Option para.graph  A,  “Shadow vehicle - in the case of mobile and constantly moving operations, such as pothole patching and striping operations, a shadow vehicle , equipped with appropriate lights, warning signs and/or or a rear-mounted impact attenuator may be used to protect the workers from impacts by errant vehicles.”

Explanations:  This change will provide an increased emphasis on workers safety.

## Qualifications for Flagger

*In Section 6E-1,*  Flagger – No definition  for a flagger was in  the MUTCD.

*In section 6E.01, 1**st** Support para.*- “A flagger is a person who provides temporary traffic control.

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6E-1, thee wasn’t a definition for a flagger.
Final Rule:  Support:  In Section 6E.01, 1st support para.graph, “a flagger is a person who provides temporary traffic control.” 

Explanation:  In the final rule, the above statement is a Support, but in the Federal Register, change #184 states the first Support sentence from the NPA has been changed to a STANDARD as the STANDARD is a definition and definitions are by their very nature STANDARDS.  This is an error and in a future rulemaking, we will changed the word Support in the heading to STANDARD.

## High-Visibility Clothing 

*In Section 6E-3, 1**st** para. , 4**th** sentence.  “*Retroreflecfive clothing design shall ... visible through full range of body motions.”

*In Section 6E.02, 1**st** Standard para.  4**th** sent. “*The  retroreflective clothing  design shall be designed ... identify wearer as a person. “

**Notes:**
1988 MUTCD:  Mandatory condition:   In section 6E-3, para.graph, 4th sentence. “ The retrorelective clothing shall be designed to identify clearly the wearer as a person and be visible through the full range of body motions.”
Final Rule:  STANDARD:  In Section 6E.02, 1st Standard para.graph, 4th sentence.   “The retroreflective clothing shall be designed to clearly identify the wearer as a person.”

Explanation:   This change was made to delete the phase “and visible through the full range of the body motions”  because a flagger visibility is the most important issue.

## Hand –Signaling Devices

- Not in the MUTCD
*In NPA, Section 6E.3,3**rd** Guidance para.* “When flashing lights are used at night, the illumination shall not blind drivers.”

*In Section 6E.03 , *the proposed statement in the NPA “ When flashing lights are used at night...

**Notes:**
1988 MUTCD: Not in the MUTCD.  However, in the NPA, Section 6E.3, 3 rd Guidance para.graph “ When flashing lights are at night, the illumination shall not blind drivers.” 
Final Rule:  The proposed statement in the NPA has been removed.
Explanations:  The proposed statement was questioned by three commenters because there is no acceptable measures to determine when flashing lights are used at night, that the illumination shall not blind drivers.  The FHWA agrees and has removed the statement from the second Guidance of this section.

## Flagger-Hand Signaling Methods

*In Section 6E-5, para. 1. “*Methods of signalizing with stop/slow paddle and flags are recommended.”

*In Section 6E.04, 1**st** Standard para.      “*Methods of signalizing  with  paddles and flags are a  standard condition.”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Not in the Current MUTCD.
Final Rule: GUIDANCE:    Section 6F-Add a description of the following signs: STAY IN LANE, PEDESTRAIN CROSSWALK, SIDEWALK CLOSED (AHEAD) CROSS HERE, RIGHT TWO LANES CLOSED 0.8 KILOMETERS (1/2 MILE), CENTER LANE CLOSED AHEAD, THUR TRAFFIC MERGE RIGHT (LEFT), EXIT OPEN, ON RAMP, RAMP NARROWS SLOW TRAFFIC AHEAD, SHOULDER WORK, RIGHT SHOULDER CLOSED, UTILITY WORK AHEAD, Lane Reduction and EXIT CLOSED.

Explanation:  This change has been made because several signs were in the Typical  Application diagrams in the 1993 Edition of MUTCD, Part 6 but there were no discussion as to their proper use.

## Colors for Guide Signs

*In Section 6F-1, para. 1,  5**th** sent.  “*Colors for guide signs  follow the ...in section 6F-1C.”

*In Section 6F.02, 1**st** Standard para., 3**rd** sent. “*Colors for guide signs shall...”

1988 MUTCD:  In Section 6F-1, para.graph  1, 5th sentence. “ Colors for guide signs follow the standard in Section 2D-3, except for special information signs as noted below in Section 6F-1C.”
Final Rule:  STANDARD:   In Section 6F.02, 1st Standard para.graph, 3rd sentence.  “Colors for guide signs shall follow the standards in Table 2A.- 4, and Chapter 2D, except for guide signs as noted in Section 6F.47.” 

Explanation:  This change has been made because it clarifies the mandatory “shall”  which is implied in the sentence. 

## Types of Devices

*In  Section, 6F, 1**st* *sent*. ”The design and application of traffic control devices used in temporary traffic control are... “

## Sign Placement

- Not in the MUTCD

*In Section 6F.03, 2**nd* *Guidance para.* added “Neither portable nor peranent sign supports should be located on sidewalks, bicycle lanes, or areas designed for pedestrian or bicycle traffic.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Not in the MUTCD.
Final Rule:  GUIDANCE:  In Section 6F.03, 2nd Guidance para.graph, “ Neither portable sign supports should be located on sidewalks, bicycle lanes, or areas designated for pedestrian or bicycle traffic.”

Explanation:  The Insurance Institute for Highway Safety commented on this omission that would have allowed the placement of temporary traffic control signs to hinder the movement of pedestrians and bicyclists.  The FHWA agrees and this should not have an impact on State or local governments.  

## Pedestrian Warning Signs 

- Not in the MUTCD

*In Section 6F.02, 2**nd** Option para. Added* ”In order to maintain the systematic use of yellow or fluorescent yellow-green background for  pedestrian....”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Not in the MUTCD.
Final Rule:  In Section 6F.02, 2nd Option para.graph was added, “ In order to maintain the systemic use of yellow or fluorescent yellow-green background for pedestrian, bicycle, and school warning signs in a jurisdiction, the yellow or fluorscent yellow-green background for pedestrian, bicycle, and school warning signs may be used in temporary traffic control zones.”

Explanation:  This Option statement was added to include the flourescent yellow-green color because many jurisdictions have adopted this optical warning sign color for pedestrian, bicyclist and school facilities and locations.  In addition, this provides more flexibility to State and local highway agencies to increase awareness of pedestrians and bicyclists in temporary traffic control zones. 

## Warning Signs Mounting Height

*In Section 6F-1, para. 7.*   “Urban  & Rural - 7 ft.”

*In Section 6F.03,  para’s.   4,  7, 8 and 11.*  ...height at ...rural area shall be mounted – 1.5m (5ft), business, commercial ...2.1 m (7ft.)     High speed- 2.1 m (5 ft).

- Yellow Text Denotes a Standard

**Notes:**
1998 MUTCD:   Recommended GUIDANCE:  In Section 6F-1, para.graph 7 & 8 .  “Signs erected at the side of the road should be mounted at a height of at least 7 feet, measured from the bottom of the sign to the near edge of the pavement. 
Final Rule:  Standard:  In section, 6F.03, para.graph 4, “ Post-mounted signs installed  at the side of the road in rural areas shall be mounted at a height least 1.5 m (5 ft), measured from the bottom of the sign to the near edge of the pavement.  In business, commercial, and residential districts where parking and/or pedestrian movement is likely to occur, or where there are other obstructions to view, the distance between the bottom of the sign and the top of the near of the traveled way shall be at least 2.1 m (7 ft).”    
Option:  In Section 6F.03, para.graph 7,  “A 2.1 m (7 ft) mounting height may be used  in rural areas for increased visibility.    In section 6F.03,  para.graph 8,  “The height to the bottom of a secondary sign mounted below another sign may be 0.3 m (9 FT) less than the appropriate height specified above.  In Section 6F.03, para.graph  11,  “Methods of mounting signs other than on posts are illustrated in Figure 6F-2.” 

Explanations:   The existing mounting height was a recommended GUIDANCE and we have changed it to a mandatory STANDARD and adding options condition to change the mounting height requirements in work zones.   There is an existing FHWA/NHSTA National Crash Analysis Study on 1.5 m ( 5 ft) versus 2.1 m (7 ft) sign mounting height. The study does not show a need to rise the sign height to 2.1 ( 7 ft)  except for visibility.  

## Amount of  Days Signs are Erected 

*In Section 6F-1, para. 8, 2**nd** sent.* “ Signs may be mounted on portable supports...”

*In Section 6F.03, 3**rd** Guidance para. “*Except as noted in the  signs mounted on portable supports should not be  used ... 3 days ... 4th Option para. The R9-8 –RR-11a  series...3 days.”

**Notes:**
1988 MUTCD:   In Section 6F-1, para.graph   8, 2nd sentence, “Signs may be mounted on portable supports for short-term, short-duration, and mobile conditions (see Section 6G-2, Selecting the Typical Application).”
Final Rule:  Guidance:  In Section 6F.03, 3rd Guidance para.graph, “ Except as noted in the Option, signs mounted on portable supports should not be used for a duration of more than 3 days.”   Option:  4th Option para., “The R9-8 through R9-11a series, R11 series, W1-6 through W1-8 series, M4-10, E5-1, or other similar type signs may be used on portable supports for longer 3 days.”
Explanations:  These changes will provide additional guidance for the amount of days that signs are to be on portable supports.

**Notes:**
1988 MUTCD:  In Section 6F-1, 8th para.graph, 4th sentence, “Unprotected sign systems should be crashworthy  (refer to the Roadside Design Guide), Chapter Nine, for additional guidance).” 
Final Rule:  STANDARD:  In Section 6F.03, 2nd Standard para.graph, “Sign supports shall be crashworthy.  Large signs having an area exceeding (50 square feet) that are installed on multiple breakaway post shall be mounted a minimum of 2.1 m (7 ft) above the ground.”  

Explanation:  (1)  The above sentence is changed from recommended condition to a STANDARD because devices, according to National Cooperative Highway Research  Program Report 350, are required to be crashworthy.  ( 2) Also, the FHWA has added the 2nd sentence above to explain the requirements for signs on multiple signs. supports.     

## Sign Maintenance 

*In Section 6F-1, para. 10, 3**rd** sent.*  “Signs are excessively  worn ... should be ... replaced. “

*In Section 6F.04.*  *Standard para., 2**nd** sent.-* “Signs that have lost significant legibility   shall be promptly replaced.”

**Notes:**
1988 MUTCD:   In Section 6F-1, para.graph 10, 3rd sentence,  “ Signs are excessive worn, scratched, bent, or have lost a significant amount of retro-reflectivity should be promptly replaced.
Final Rule:   STANDARD:  In Section 6F.04 Standard para.graph, 2nd sentence, “ Signs that have lost significant legibility shall be promptly replaced.” 

Explanation:   The above text was changed from recommended condition to Standard because FHWA feels that this would increase visibility and safety.  

## THE ROAD (STREET) CLOSED SIGN 

*In Section 6F-1a(4).* “THE ROAD CLOSED sign may be used where ...beyond this sign.”

*In Section 6F.08, Guidance para.*  “THE ROAD  STREET (CLOSED)  sign should be used  ...appropriate warning and detour signing.”

**Notes:**
1988 MUTCD:  In Section 6F-1a(4), “THE ROAD (STREET) CLOSED sign may be used where the roadway is closed to all traffic except contractors’ equipment or officially authorized vehicles an may be accomplished by appropriate detour signing.”
Final Rule:  GUIDANCE:   In section 6F.08, Guidance para.graph  “ The ROAD  (STREET) CLOSED sign (R11-2) should be used when the where the roadway is closed to all road users except contractors’ equipment or officially authorized vehicles.  The R11-2 sign should be accompanied by appropriate warning and detour signing.”

Explanation:  The above para.graph will changed from a permissive condition to a GUIDANCE to provide additional guidance for safety. 

## LOCAL TRAFFIC ONLY SIGN

- Not in the MUTCD
*1999 NPA-In Section 6F.9* *Standard para.* “In rural applications –LOCAL TRAFFIC shall...to the point of closure.”

*In Section 6F.09 2**nd**  Guidance para.. “* In rural applications- LOCAL TRAFFIC  should...have the legend  ROAD CLOSED ... (R11-3a).”

Explanation:   In the NPA, in Section 6F.9, LOCAL TRAFFIC ONLY Signs (R-11-3,R11-4), the FHWA has changed the first STANDARD statement to a Guidance statement to provide more flexibility in signing in rural communities where the temporary traffic control zone may be within a residential block and not kilometers (miles) down a road without intersections.   

## Flexible Warning Signs

- Not in the MUTCD

NPA:  STANDARD:   In NPA, Section 6.F16, para.graph 14 & 15, read as “ Flexible waning signs for nighttime use shall have a black legend on a retroreflectorized orange or retroreflectorized flourescent orange background .  The mounting height of flexible signs shall conform to the same requirements as rigid signs.” 
Final Rule:  STANDARD:  The above para.graph 14 has been removed and addressed in the Final Rule in Section 6F.02, General Characteristics of Signs, 1st Standard para.graph, 2nd sentence, “Warning signs in temporary traffic control zones shall have a black legend on an orange background, except for the Railroad Advance Warning (W10-1) sign which have a black message and border on a yellow background, and except for signs that are permitted in Part 2 to have or flourescent yellow-green backgrounds.”  Also in the Final Rule, in Section 6F.15 Warning sign function (as referenced in the NPA) has been combined with Section 6F.16 Warning Sign Design and Application (as referenced in the NPA), and renamed, “ Section 6F.15 Warning Sign Function, Design, and Application.”
Explanation:  In Section 6F.15 Warning Sign Function, Design, and Application, the STANDARD and GUIDANCE statements proposed in the NPA concerning flexible signs have been removed as these items are adequately addressed in Section 6F.02 Signs, and in Section 6F.03 Sign Placement.  Five commenters indicated this overlap and FHWA agreed, therefore, we have moved the Standard and Guidance statement.  These changes were made because the FHWA agrees with the comments from five commenters that the material in the two sections really belongs together.

Where a series of two or more warning signs is used, the closet sign to the work area should be placed approximately 200 feet away for low-speed urban streets to 1,000 feet away or more for expressways and freeways. In Section 6F.16, 1st Support para.graph, “Various conditions, such as limited sight distance or obstructions that might require a driver to reduce speed or stop, might require addditional advance warning signs.’’
Explanation:  Section 6F.16, Position of Addvance warning sign (referenced as Section 6F.17 in the NPA) has been combined with Section 6F.18 Other Advance warning Signs (as referenced in the NPA) and Section 6F.19 Application of warning, Minor Road work, and Utility sites (as referenced in the NPA) and has been moved and named, “Section 6F.16 Position of Advance Warning Signs,”. These changes were made because the FHWA agrees with the five commenters that indicated the overlap in technical issues in these three sections.

Final Rule:  In Section, 6F.20 ONE LANE ROAD Sign (W20-4) (referenced in the NPA as Section 6F.23 and Section 6F-1(9) 2nd para.graph), the FHWA has moved to Section 6C.10 One-Lane, Two Way Traffic Control, 3rd GUIDANCE para.graph concerning how to temporarily control two-way traffic on a one-lane roadway.  This Guidance para.graph has been reworded to read, “ If traffic on the affected one-lane roadway is not visible from one end to the other, then flagging procedures, a pilot car, or traffic signal control should be used to control opposing traffic flows.”

Explanation:  This Guidance statement has been moved for clarification and is more appropriately placed in Section 6C.10    l

Final Rule:  In Section 6F.52, 1st Support para.graph, “ Portable Changeable Message Signs are temporary traffic control devices with flexibility to display a variety of messages.  Each message consists of either one or two phases.  Typically, a phase consists of up to three lines of eight characters per line.”  

Explanation:  In the Federal Register, comment #194 states that the FHWA has changed the first Support statement in the NPA to a STANDARD statement as the statement is a definition and definitions are by their nature STANDARDS. Also, this is an error and in a future rulemaking, we will changed the word “Support” in the heading   to “Standard”.

This sign is intended to provide additional warning and directional information to assist in merging and controlling road users through or around a temporary traffic control zone.”  (2) Additionally, since arow panels are similar to provide portable changeable messages signs, the FHWA has added a Guidance para.graph for locating and providing protection for arrow panels,  In Section 6F.53, 2nd GUIDANCE para.rgraph reads “An arrow panel should be placed on the shoulder of the roadway or, if practical further from the traveled lane.  It should be delineated with retroreflective temporary traffic control devices, or when within the clear zone, shielded with a barrier or crash cushion.  When an arrow panel is not being used, it should be removed; if not removed, it should be shielded; or if the previous two options are not feasible, it should be delineated with retroflective temporary traffic control devices.  

Explanation: (1)  In the Federal Register, comment#195 states that the FHWA has changed the first Support Statement in the NPA to a STANDARD statement as the statement is a definition and definitions are by their nature STANDARDS.  This as an error and in a future rulemaking, we will changed the word “Support” in the heading to “STANDARD”.  (2)  This GUIDANCE will maintain traffic flow efficiency and improve safety. 

## Type D Arrow Panels

- Not in the MUTCD.

*In Section 6F.53, 2**nd **, 3**rd **&** ** 7**th** Standard para. “*A * *Type D arrow panels shall conform  to shape of ... the arrow.

**Notes:**
1988 MUTCD:  Not in the MUTCD.
Final Rule:  Support: “Type D panels are intended for use on authorized vehicles.”
STANDARD:  “A Type D arrow panel shall conform to the shape of the arrow.  All panels shall be finished in non-reflective black.  The panel shall be mounted on a vehicle, a trailer or other suitable support.”  An arrow panel shall have the following three mode selections:
  Either a Flashing arrow, sequential arrow, or Sequential chevron mode, and
  A flashing double Arrow mode, and 
  A flashing caution mode.”

Explanation:   To explain how this type of arrow panels should be used. 

## Channelizing Devices

*In Section 6F-5, 7**th** para.graph, 3**rd** sent. & in the NPA, 4**th** Support para. “*Standard design of channelizing devices are shown in ...”* *

*In Section 6F.55, 1**st** Support para. 1**st** sent.,”*Designs of various channelizing devices are shown in Figure 6F-4.”*  *

**Notes:**
1988 MUTCD:  In Section 6F-5, 7th para.graph, 3rd sentence & in the NPA, 4th Support para.graph,  “Standard designs of channelizing devices are shown in figure VI-10.”
Final Rule:  Support:  In Section 6F.55, 1st Support para.graph, “Designs of various channelizing are shown in Figure 6F-4”.

Explanation:   In the Federal Register, comment #196 states that the FHWA changed the fourth Support para.graph in the NPA to a STANDARD because the design dimensions in Figure 6F-06 have always been STANDARDS. One commenter pointed out this discrepancy and we agreed with the comment.  This is an error and in a future rulemaking, we will changed the word “Support” in the heading to “STANDARDS”.  

## Direction Indicator Barricade

- Not in the MUTCD
*NPA Section 6F.58G, 2**nd** Guidance para.* “The direction Indicator Barricade should be used in tapers , transitions and other areas...”

*In Section 6F.61,*_*** ***_*Option para.* “ The direction Indicator Barricade may be used in tapers, transitions, and other areas...“

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

**Notes:**
1988 MUTCD:   Not in the MUTCD, however in the NPA. Section 6F.58G, 2nd Guidance para.graph, “The Direction Indicator Barricade should be used in tapers, transitions, and other areas where specific directional guidance to motorists is necessary.”
Final Rule:  Option:  In Section 6F.61, Option para.graph, “The Direction Indicator Barricade mayy be used in tapers, transitions, and other areas where specific directional guidance to drivers is necessary.  

Explanation:  Direction Indicator barricades do not have to always be used in these situations.  This change provides State and local highway agencies more flexibility in selecting temporary traffic control devices for work zones.

## Drums

- Not in the MUTCD.

*In Section 6F.59, 1 st Standard para. 5th sent.  “*Each drum ... shall  have a minimum of top two orange and white stripes with the top stripe being orange.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6F-5e, no mention of top stripe color on drum.
Final Rule:  STANDARD:  In Section  6F.59, 1st Standard para.graph, 5th sentence, “Each drum shall have a minimum of two orange and two white stripes with the top stripe being orange.”

Explanation:  This change will provide better uniformity on the top color of all drums.    

## Temporary Raised Island (TLTWO)

-  Not in the MUTCD.*  *

*In Section 6F.63, 1**st **Option para. “ *A temporary raised island may be used  to....traffic volumes range of 4,000 to 15,000 ADT, freeways ...22,000 to 60,000 ADT.”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:   Not in the MUTCD.
Final Rule:  Option:  In Section 6F.63, 1st Option para. “ A temporary raised island may be used to separa.te motor vehicle traffic flows in two-lane, two-way operations on roadways having a motor vehicle traffic volume range of 4,000 to 15,000 average daily traffic (ADT) and on freeways having a motor vehicle traffic volume range of 22,000 ADT to 60,000 ADT.”

Explanation:  This change was made to provide guidance in the use of temporary raised island which is published in AASHTO 1996 Roadside Design Guide in Chapter 9.      

##  Temporary Pavement Markings

*In Section 6F-6b(1)* Interim Markings-“All interim broken-line  pavement markings shall use the same cycle length as....4 feet... long.“

*In Section 6F.66 1**st** Standard para., 2**nd** sent.,  “*All temporary broken-line  pavement markings shall use the same cycle length  as permanent markings and be at least 0.6 m ( 2 ft) long.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section 6F-6b(1), “All interim broken-line pavement markings shall used the same cycle length as permanent markings and be at least 4 feet long, except that half-cycle lengths with a minimum a minimum of 2-foot stripes may be used for roadways with severe curvature.”
Final Rule:  STANDARD:    In  Section 6F.66, 1st Standard para.graph, 2nd sentence:  “All temporary broken-line pavement markings shall be the same cycle length as permanent markings and be at least 0.6 m (2 ft) long.”

Explanation:   This change was made because of a Texas Transportation Institute Research Record 1160,  Field Studies of Temporary Pavement Markings at Overlay project Work zones on Two-lane, Two-way rural Highways, indicates that there is no significant difference between the performance of the 1.2 m (4 ft)  broken line or the 0.6 m (2 ft) broken line.  

## Raised Pavement Markings

*In Section 6F-6c, para. 2,  *Raised pavement markings may be substituted ... supplement ...* *** **

*In Section 6F.67, Stnadard para.*, “ If raised pavement markings ... substitute ... shall be placed ... 0.6 m (2 ft) to 1.5 m (5 ft).  For segments over 1.5 m (5 ft) .

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:   In Section 6F-6c, para.graph  2, “Retroreflective raised/recessed pavement markers, or non-retroreflective raised/recessed pavement markers supplemented by retroreflective markers, may be substituted for, or used as a supplement to markings prescribed in sections 3A and 3B and subsection b, above.  (Read Section 3A.16 and 3B.16).
Final Rule:  STANDARD:   “If raised pavement markers are used to substitute for a broken line segments, at least two retroreflective markers shall be placed, one at each end of a segment of 0.6 m (2 ft) to 1.5 m (5ft).  For segments over 1.5 m  (5ft), a group of at a least three retroreflective markers shall be equally spaced at no greater than N/8.  The value of N for a broken or dotted line shall equal the length of one line segment plus one gap.  The value of N referenced for solid lines shall equal the N for the broken or dotted lines that may be adjacent to or may extend the solid lines ( see Chapter 3B).”

Explanation:   This change allows fewer raised pavement markings for a broken line segment.

## Warning Lights

*In Section 6F-7e, para. 5, “*Type C steady-burn lights are intended to be used to delineate the edge of the traveled way on detour curves ...*”*

*In  Section 6F.72,  2**nd **Guidance  para.,*  “When used to delineate a curve, Type C warning lights should only ...curve, and not on the  inside of curve.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  In Section, 6F-7e,  para.graph 5,  Type C steady-burn lights are intended to be used to delineate the edge of the traveled way on detour curves, on lane changes, on lane closures, and on other similar conditions.”
Final Rule:  GUIDANCE:  In Section 6F.72, 2nd Guidance para.graph, “When used to delineate a curve, Type C warning lights should only be used on devices on the outside of the curve, and not on the inside of the curve.

Explanation:   This change will add the new GUIDANCE discussion to ensure lights are put on the outside of the curve to improve delineation of the curve. 

## Temporary Traffic Control Signals

- Not in the MUTCD*.*

*In Section 6F.74, 1**st** Guidance  para. *”When temporary traffic control signals are used, conflict monitors typical of traditional traffic control operations should be used.”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  Not in the MUTCD. 
Final Rule:   GUIDANCE:   In  Section 6F.74, 1st Guidance para.graph, “Temporary Traffic Control Signals (referenced in the NPA as Section 6F.61, 1st Guidance para.graph read as “Whenever the distance between traffic signals is long or restricted, the use of conflict monitors or similar electronic technology that is typically used in traditional traffic signal operations should be considered).  The above Guidance para.graph is revised to read, “When temporary traffic control signals are used, conflict monitors typical of traditional traffic control operations should be used.”  

Explanation:  This correction was made because the spacing between traffic signal installations, as proposed in the NPA, had nothing to do with the need for conflict monitor.  This will have no impact on State or local governments since the FHWA is retaining existing MUTCD requirements. 

## Temporary Traffic Barriers

*In Section 6F-8b, 4**th** para.* The effect of striking the ends...
*In NPA, Section 6F.62, 2**nd** GUIDANCE para.* “the ends of the temporary barriers should be ...”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:   In Section 6F-8b, 4th para.graph, “The efect of striking the ends of barriers should be mitigated by use of impact attentuators or by flaring the ends of barriers away from the traveled way.”
In the NPA, Section 6F.62, 2nd GUIDANCE para.graph, “The ends of the temporary barriers should be flared or provided with crashworthy end treatments in accordance with the AASHTO Roadside Design Guide in order to mitigate the effect of striking the ends of temporary barrier.”
Final rule:  STANDARDS:  In Section 6F.75, 2nd STANDARD para.graph, “ In order to mitigate the effect of striking the end of a temporary traffic barrier, the end shall be installed in accordance with AASHTO’s Roadside Design Guide by flaring until the end is outside the acceptable clear zone or by providing crashworthy end treatments.”
Explanation:  The FHWA has changed a GUIDANCE statement in the NPA to a STANDARD statement.  This change should improve safety because research indicates that there are no acceptable methods of providing the required degree of safety other than flaring or providing crashworthy and end treatments. 

## Truck-Mounted Attenuators

- Definition of Truck –Mounted Attenuators was not in the MUTCD.
*In the NPA, Section 6F.63B, 2**nd**  Support para.,* “Truck-mounted Attenuators are energy absorbing...”

*In Section 6F.76, 3**rd** Support para., *Truck-mounted attenuators are energy-absorbing devices attached...
*In Section 6F.76, 3**rd** STANDARD para., *“The shadow truck shall be positioned a sufficient distance  in advance...”

_**1988 MUTCD**__**	**__**	**__**    2000 MUTCD**_

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  There wasn’t a definition for a truck–mounted attenuator in the 1988 MUTCD.  However, in the NPA, Section 6F.63B, 2nd Support para.graph, Truck-mounted attenuators (TMA’s) are energy absorbing devices attached to the rear of shadow trailers.”
Final Rule:  Support:  (1) In Section 6F.76, 3rd Support para.graph, should be a STANDARD because it a definition of truck-mounted attenuators.  It reads “Truck-mounted attenuators are energy-absorbing devices attached to the rear of shadow trailers or trucks.”  (2)  In Section 6F.76, 3rd Standard para.graph should be a GUIDANCE para.graph.  It reads “ The shadow truck shall be positioned a sufficient distance in advance of the workers or equipment being protected so that there will be sufficient distance, but not so much so that errant vehicles will travel around the shadow truck and strike the protected workers and/or equipment.”

Explanation:  In the Federal Register, comment #200 states that the FHWA has changed the word “Support” in the 3rd Support heading to Standard as the STANDARD is a definition and definitions are by their nature STANDARDS.”  This change was added to define what is a truck-mounted attenuator. (2)  In Section 6F.76, 3rd STANDARD para.graph should have been a GUIDANCE para.graph, because this para.graph provide more flexibility in the spacing of the shadow vehicle behind the workers and their work vehicles.  The above errors in the para.graph headings will be changed in a future rulemaking.

## Spacing of Shadow Truck 

*In Section 6F-8a(2),3**rd** para., *”The protective truck must be positioned, a sufficient distance...”

*In Section 6F.76, 3**rd** Standard para.,* “The shadow truck shall be positioned a sufficient distance in advance ...”

**Notes:**
1988 MUTCD:  Mandatory Condition: In Section 6F-8a(2), 3rd para.graph “The protective truck must be positioned a sufficient distance in front of the workers or equipment being protected to allow for appropriate vehicle roll-ahead, but not so far that errant vehicles will travel around the vehicle and strike the workers/equipment.”
Final Rule:  STANDARD:  In Section 6F.76, 3rd STANDARD para.graph, should be a Guidance. It reads, “The Shadow Truck shall be positioned a sufficient distance in advance of the workers or equipment being protected so that there will be sufficient distance, but not so much so that errant vehicles will travel around the shadow truck and strike the protected workers and/or equipment.”
Explanation:  This is an error in the Millennium Edition and in a future rulemaking, we will changed the word “STANDARD” in the heading to “GUIDANCE”.  This change was made to provide more flexibility in the spacing of the shadow vehicle behind the workers and their work vehicles.

## Future and Experimental Devices

- Not in the MUTCD

Explanation:   This new section will provide  information on the use of future and experimental products.  

## Duration of Work

*In Section 6G-2a,  2**nd** bullet, *“Intermediate-term stationary- Work that occupies ... overnight to 3 days.”

*In Section 6G02. 1**st **Standard para., 2 bullet-”*Intermediate-term stationary-... more than 1 daylight period ...up to 3 days...night time... more than 1 hour.”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:  “In Section 6G-2a, 2nd bullet “ Intermediate-term stationery-Work that occupies location from overnight to 3 days.”
Final Rule: STANDARD:  In Section 6G.02, 1st Standard para.graph, 2nd bullet,
“ Intermediate-term stationary is work that occupies a location more than one daylight period up to 3 days, or nighttime work lasting more than 1 hour.”

Explanation:    This change was made to add to the above phase about nighttime work to further explain intermediate-term stationery work at night. 

## Intermediate-Term Stationary

*In Section 6G-2a, *no discussion about nighttime work and devices.

*In Section 6G.0.2, 3**rd** Standard para.,* “Since  intermediate –term ... retroflective and/or illuminated devices shall be used.”

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:   In Section 6G-2a, no discussion about nighttime work and the use of retroreflective and /or illuminated devices.
Final Rule:  STANDARD:  In Section 6G.02, 3rd Standard para.graph,  “ Since intermediate-term operations extend into nighttime, retroreflective and/or illuminated devices shall be used in intermediate-term stationary temporary traffic control zones.”

Explanation:  This STANDARD was added because a good safety design feature for any/all nighttime work is one that is properly delineated with retrofelective signs and/or illuminated devices.

## Multilane Non-Access Controlled

- Yellow Text Denotes a Standard

**Notes:**
1988 MUTCD:   In Section 6G-7, there is no discussion on lane closures and merging taper.
FINAL RULE:  STANDARD:  In Section 6G.11, 2nd Standard para.graph, 2nd sentence, “For lane closures, the merging taper shall use channelizing devices and the temporary traffic barrier shall be placed beyond the transition area.”

Explanation:  This change will provide proper delineation of a lane closure to the road user.  

## Work Outside of Shoulder

- Not in the MUTCD
*NPA, in Section 6G.6,2**nd** GUIDANCE para.,* “Where the activity is spread out over a distance of more than 3.2 km (2 mi)...”

*In Section 6G.05, 2**nd** Guidance para.,* “Where the acitivity is psread out over a distance of more than 3.2 km (2 mi) ...”

**Notes:**
1988 MUTCD:  Not in the MUTCD, however in the NPA, Section 6G.6 2nd Guidance para.graph reads” where the activity is spread out over a distance of more than 3.2 km (2 mi), the sign should be repeated every 1.6 km (1 mi).”
Final Rule: GUIDANCE:  In Section 6G.05 2nd GUIDANCE para.graph reads “Where the activity is spread out over a distance of more than 3.2 km (2 mi), the SHOULDER WORK sign should be repeated every 1.6 km ( 1 mi).”  This statement is an error because in the Federal Register, comment# 201, states the FHWA has changed the above GUIDANCE statement to an Option statement which has not been done.  Therefore, correction will be done in a future rulemaking. 

Explanation:  The reason for the change from a GUIDANCE statement to an Option was because the work being performed is outside of the shoulder, and there may not always be a need to install signs that freguently.  Also, this change will provide more flexibility to State and local highway agencies.  

## Work on the Shoulder with No Encroachment 

- Not in the MUTCD.

*In Section 6G.07, 2**nd** GUIDANCE para. *“Truck off-tracking should be considered when determining the minimum lane  width of  3 m (10 ft) is adequate.”

Final Rule:  In Section 6G.07, 2nd GUIDANCE para.graph, ‘ Truck off-tracking should be considered when determining whether the minimum lane width of 3 m (10 ft) is adequate.”

Explanation: The above statement was added from Figure 6H-43, Partial Exit Ramp Closure to this section because minimum lane widths are discussed and accounting for truck off -tracking is applicable to all temporary traffic control zones with minimum lane widths.  

## Work within the Median

*In Section 6G-2b(3) & in NPA, Section 6G.3, GUIDANCE para. *”If work in the median of a divided highway is within 4.5 m (15 ft)...”

Final Rule:  STANDARD:  “If the temporary traffic control zone affects the movement of bicyclists, adequate access to the roadway, bicycle paths, or shared-use paths shall be provided (see Part 9).”
Explanation:  In Section 6G.10 Work within Traveled Way of Urban Streets, Subsection B. Bicyclists, the FHWA has changed a proposed Support statement to a STANDARD statement to ensure the bicyclists are accommodated during a temporary traffic control zone.  This change should provide for increased safety for bicyclist in temporary traffic control work zones and has no significant impact on State or local government agencies.

Explanation:  On March 17, 1993, a tractor-semitrailer hauling gasoline was struck by a National Railroad Passenger Corporation (Amtrak) train resulting in the truck driver and five occupants of three stopped vehicles being killed.  The truck driver was attempting to cross a highway-rail grade crossing  on Cypress Creek in  Fort Lauderdale, Florida and traffic in the area of the crossing was congested because the left and center lanes were closed just beyond the crossing.  As a result of the investigation of the crash, National Transportation Safety Board (NTSB)  recommended that the FHWA provide information on channelization of traffic at a work zones to minimize traffic congestion over highway-rail grade crossings.  The above mentioned notes and figures are in compliance with the NTSB’s recommendation.  Also, the above changes have been added to provide information for safe and efficient operation of both highway and rail traffic at highway-rail grade crossings within construction and maintenance work zone limits.

Final Rule:  GUIDANCE:  In Section 6H.01, Notes for Figure 6H-39(TA 39),  Note 6: “When channelizing devices have the potential of leading traffic out of the intended traffic space, the channelizing devices should be extended a distance in meters (feet) of 0.4 the speed limit in km/h (2 times the speed limit in mph)  beyond the end of the transition area as depicted.”  

Explanation:   This change will address a problem of poor guidance for traffic traveling through a two-lane, two-way operation at the end of the construction zone.  Consequently, truck drivers with driver eye height substantially above the road cannot see well enough through adverse weather conditions (fog, heavy rain, snow squalls, etc.) to find anything except the barrels leading back cross the median.  They too often  follow the backside of those barrels into the median, resulting in crossover embankment collision, median side slope rollover, and bridge rail impact.  If  we are going to use delimeators to separa.te two-lane, two way traffic in construction  zones, provisions should be made to extend the line of delineation well beyond the end of two-lane, two-way traffic in order to achieve “continuity” to fulfill” driver expectancy” under  low visibility conditions.
