## FHWA Workzone Facts

**Between 1980**** ****and 1998, vehicle travel was up 73%, while the number of road miles increased by only 1%.**
**13% of the National Highway System is under construction at any given time.**
**24% of non-recurring congestion is due to work zones.**
**Motorists are less tolerant with delays especially those associated with workzones.**

## Resulting in......

## ....and.....

## FHWA Goals

**Reduce work zone delay by ensuring all states are engaged in aggressively anticipating and **_**mitigating congestion**_** caused by highway work zones. **
**Actions for use by State Agencies:**
**1) Develop methods for measuring and monitoring delays in work zones**
**2) Use available technology to reduce congestion in workzones.**
**3) Provide automated, real time travel information**** ****in advance of the work zones.**

## What is North Carolina doing?!#

**NCDOT is proactively deploying the technology to mitigate congestion in highway work zones**

**hmm.....SMART Work Zones**

## Slide 8

## What is a SMARTZONE and how do they work?

**“****SMARTZONE” or ‘SMART Work Zone’ is the term commonly used to describe the technology and equipment that monitors and manages traffic congestion due to work zones.**
**Typically these systems incorporate roadside speed and volume sensors to detect work zone congestion. **
**This information is then transmitted to an on-site computer via radio, cellular or satellite communication for processing. **
**The corresponding delay information is displayed on portable changeable message signs in an automated, real-time manner. **
**In some cases, once the delay exceeds a threshold, alternate route messages may be displayed.**

## OUR SMARTZONE GOALS

**Mitigate queues to 2 miles or less. **

**Virtually eliminate “rear end” crashes due to queues.**** **

**Earn trust with motorists to reestablish compliance with work zone information. We want to exceed our customers’ expectations !!**

**Provide real time delay information in advance of work areas.**** **

**Utilize alternate routes where available to reduce volume thru work area.**

**Eliminate Fatalities due to excessive traffic queuing in highway work zones.**

**Use this Technology to:**

## How much does it cost?

**Depends on how much equipment is necessary to provide the required monitoring.**
**Depends on length and duration of work zone and if both directions need simultaneous monitoring**
**Depends on the type of communication technology that is required ( i.e. radio versus cellular and satellite) **
**Depends on the complexity of the individual vendors system ( i.e. software cost, communication costs, etc.)**

## What are the measurable results?

**Reduction of Congestion associated with lane closures **
**Reduction/elimination of “rear end” crashes due to excessive queuing**
**Reduction/elimination of Fatal Crashes due to excessive queuing**
**Increased Productivity for the Contractor**

## Intangible Factors

**Believable, Real Time information resulting in better compliance with work zone information.**
**Better relations with the media industry which in turn is used as the key link to provide information to the public.**
**Improved Communication with the Motoring Public resulting in improved Department Image**
**Regaining the trust from the motoring public....providing them the information they want and need and more importantly...**_**when**_** they need it!**

## News and Observer Article

-                  By VICKI HYMAN
-                  Until now, I've never found cause to string
-                  together the words "North Carolina Department
-                  of Transportation" with "cool."
-                  The state has installed its first "smart work
-                  zone" on Interstate 95 outside Fayetteville,
-                  equipping the highway with sensors to detect
-                  speed, calculate traffic conditions and relay
-                  real time information to electronic message
-                  boards and a Web site.
-                  I'm not talking messages like "Delays Ahead"
-                  or "Expect Congestion" that you might see on
-                  I-40 around rush hour. With all due respect to
-                  the technicians who spend hours monitoring
-                  traffic conditions via live feeds from cameras
-                  posted along the highway, let me just say, "No
-                  duh."
-                  The messages posted on I-95 can tell drivers,
-                  to the minute, how long a delay to expect.
-                  Once the delay reaches 10 minutes, the
-                  electronic message boards offer alternate route
-                  information. The state has placed the message
-                  boards far enough ahead of the backups to give
-                  drivers a way out before they actually hit the
-                  traffic.
-                  On the Web site,
-                  http://www.I95fayetteville.com, you can even view how fast traffic is moving
-                  through the work zone.

## I-85 Hydroplane System

## I-95 SMARTZONE Problems

**Downtime due to equipment malfunction primarily caused by lightening strikes**

**Communication problems with cameras. **

**Availability of speed, volume and video information**

**Under-powered camera/sensor equipment**

**Downtime due to communication disruption**

## Future Changes

**Utilize “on-site” technician**

**Improve Departments access to speed, volume and video information via the website**

**Utilize pay reduction for system downtime**

**Have system notify (via Page, email, cell phone) appropriate personnel if a malfunctions occurs**

**Improve messages on CMS’s to enhance ridership on the Alternate Routes**

## So far....what we think we know

**1) SMARTZONES “AIN’T” a substitute for sound traffic engineering**** **

**SMARTZONES work well on rural interstates with AADT’s up to 55,000 with available alternate routes. Interstate Rehabilitation Projects are ideal!....primarily due to their high frequency of lane closure**
**(continued next page)**

**2) Need to understand what you want the system to do before you let a contract**

**Guidelines for application**

## Guidelines Continued 

**SMARTZONES may have limited applications on high volume roadways (above 65,000) with few reasonable alternate routes. However, if reoccurring congestion is a problem, the technology could provide real time, delay information in lieu of congestion mitigation.**

**SMARTZONES may have applications on roadways with higher AADT’s (55,000 to 65,000) where we traditionally restrict lane closures to nightly activity. **
**You may look at using the SMARTZONE technology to mitigate the congestion during non-peak hour flow. Use traditional lane closure restrictions for peak hour.**

**SMARTZONES can also be used for more traditional problems such as speeding and site condition problems such as hydroplaning and/or severe alignment concerns.**

## SMARTZONE EVOLUTION... What have we done and where do we go from here?

** ****Fayetteville project is redeployed and will remain active thru the Fall of 2003. Access to the site at www.i95fayetteville.com **
** ****Have 2 other contracts let on I-95 that are deployed. 1 of these incorporates**** moving alternate route locations! ****These deployments can be accessed from the following websites: ****https://tm100.irdinc.com/nci95nash/public https://tm100.irdinc.com/nci95johnston/public**
** ****The 4th deployment is just underway in Johnston County near the Four Oaks interchange (MP 87)**
**Using this technology to help hydroplaning issues on I-85 outside of Charlotte (MP 29)**
