Executive Summary

In the 2012 reporting period, the Montana Department of Transportation (MDT) successfully 

utilized our allotted Highway Safety Improvement Program (HSIP) funds on Montana's 

roadways. MDT also completed Corridor Safety audits (CSA) on two locations in the state. 

Recommendations from these CSA's are being utilized to supplement our historical site specific 

identification of safety improvements. MDT is moving forward with upgrading of our safety 

analysis software and is developing a Roadway Departure Safety Implementation Plan. MDT 

continues to evaluate our historical processes for identifying locations for safety improvements 

and is discussing how to balance our site specific program with systemic improvements. Overall 

crash trends for fatal and severe injury crashes in the state had a slight increase in 2012 as 

compared to 2011; however, overall fatalities and serious injuries are down over 21% since the 

establishment of the goal in 2007.

Introduction

The Highway Safety Improvement Program (HSIP) is a core Federal-aid program 

with the purpose of achieving a significant reduction in fatalities and serious 

injuries on all public roads. As per 23 U.S.C. 148(h) and 23 CFR 924.15, States are 

required to report annually on the progress being made to advance HSIP 

implementation and evaluation efforts. The format of this report is consistent 

with the HSIP MAP-21 Reporting Guidance dated February 13, 2013 and consists 

of four sections: program structure, progress in implementing HSIP projects, 

progress in achieving safety performance targets, and assessment of the 

effectiveness of the improvements.

Describe how local roads are addressed as part of Highway Safety Improvement Program.

Crash data is available for local roads; however, the ability to query the data based on local 

road route and milepost is very limited. MDT has developed a process to generate approximate 

coordinates for crashes coded to off-system routes. Additionally, traffic volume and roadway 

characteristics data is generally not available for the local routes. MDT has made an effort to 

identify crash clusters on the local road system using the crash data and querying

methodologies currently available. MDT also offered to provide information on the HSIP to the 

local government officials during one of their annual conferences; however, no space was 

available on the agenda. 

Fatal crash data is available for the Tribal reservations; however, other crashes investigated by 

the Tribal enforcement agencies are not consistently submitted. MDT solicits participation from 

local and Tribal agencies, who can submit documentation of sites to be evaluated and 

prioritized under the Highway Safety Improvement Program. A nomination/application for HSIP 

projects is attached to this report and is also included on the MDT internet page at: 

http://www.mdt.mt.gov/publications/docs/forms/hsip_application.pdf. MDT presented 

information on the HSIP at the Annual Tribal Transportation Safety Summit held in June 2012. 

This presentation provided information to Tribal officials on the MDT HSIP as well as 

information on how Tribal governments can apply for safety funding through the HSIP 

application.

primarily on severity. Enforcement agencies identify locations and request site reviews. Local 

and Tribal agencies can forward safety projects or request MDT evaluate areas of interest. MDT 

District Offices also submit sites for investigation and participate in the engineering study to 

determine crash trends and countermeasure selection. Project selection is currently based on 

the benefit/cost ratio method. MDT has advanced some systemic improvements (curve signing 

as an example) based on the strategies outlined in the Comprehensive Highway Safety Plan. 

Appropriate entities within MDT are invited to participate in the Road (Corridor) Safety audits. 

These entities include, but may not be limited to, the State Highway Traffic Safety Office, 

Planning Division, Motor Carrier Services, Road Design, Traffic Operations, Maintenance, and 

District personnel.

Describe any other aspects of Highway Safety Improvement Program Administration on which you 

would like to elaborate.

Since 2006 Montana has had a Traffic Records Coordinating Committee (TRCC). The TRCC has representation from 

State agencies involved with safety records and Federal agencies for oversight and input. They meet regularly and 

attempt to coordinate and share projected record upgrades, new projects and pertinent records among participants. 

As the systems mature, the TRCC may include MPO and Tribal representation.

Starting September 2008, the Montana Highway Patrol (MHP) implemented the CTS America Public Safety System 

dispatch-crash-record systems, including a MMUCC based crash reporting form. MHP investigates approximately 

50% of all statewide crashes. This CTS America System is presently only used by the MHP via a mobile client in 

each patrol unit; however, a web-based crash reporting system is being developed to allow local enforcement 

agencies to input crash information via the internet, if they choose to participate. The project is starting with the eight 

largest local Police Departments. These eight departments report about 80% of all local crashes.

This change of crash reporting forced MDT to map the MMUCC data elements to the present MARS (Montana 

Accident Record System) crash data base. MDT has developed a process to approximate crash locations between 

GPS longitude and latitude and route, mile marker, and mile marker offsets. MDT also has processes in place to 

approximate the location of crashes occurring on off-system routes which are coded to a Township, Range and 

Section. MDT has access to the MHP crash investigator’s reports, if additional detail on the particular crash is 

required. MDT is in the process of developing a Request for Proposal for a potential upgrade to the data system and 

analysis tools used to evaluate safety data.

MDT has implemented a Linear Referencing System. The LRS is complete on all roads open to public travel in the 

state. The current road log has information on roadway width, number of through lanes and shoulder widths. MDT is 

currently evaluating the guidance provided by FHWA on the collection of the Model Inventory of Roadway Elements 

(MIRE). MDT has purchased additional hardware for the photo-log vans which will allow for additional data collection 

which may include horizontal and vertical alignments, superelevation and roadside inventory.

The Office of Court Administration (OCA) maintains a central court repository (CCR), which contains electronic case 

records from all Courts of Limited Jurisdiction and District Courts. The CCR includes records on all citations, as well 

as corresponding disposition information. The Department of Justice (DOJ) receives any CCR information that must 

be applied to a driver’s record. Working with the OCA and the DOJ, MDT receives the same driver information for use 

in traffic safety analysis. While the data is not yet available for traffic safety users, a project to increase the scope of 

the data received and to develop the reports and analysis needed is listed as a medium priority in the Montana Traffic 

Records Strategic Plan Annual Element.

The Traffic and Safety Bureau is actively involved in the implementation and update of the Strategic Highway Safety 

Plan also known as the Comprehensive Highway Safety Plan. Traffic and Safety is taking the lead in the areas of 

single vehicle run-off-the-road/road departure crashes and in the rural high-crash severity corridors and high crash 

locations. MDT is conducting a minimum of two Road Safety audits per year on identified rural high crash corridors.

Describe any other aspects of the Highway Safety Improvement Program methodology on which you 

would like to elaborate. 

The following is a summary of the criteria utilized to identify high crash locations for the 2012/2013 HSIP. All 

segment lengths were 0.5 miles. 

Severity Index (SI) – Greater than one and a half (1.5) times the statewide average meeting the following criteria: 

 

Interstate, NINHS routes = 5 years (2007-2011), minimum 5 crashes. 

State Primary routes = 5 years (2007-2011), minimum 5 crashes. 

State Secondary routes = 10 years (2002-2011), minimum 5 crashes. 

State Urban routes = 3 years (2009-2011), minimum 5 crashes. 

Severity Rate (SR) - minimum severity rate six (6) times the statewide average meeting the following criteria: 

 

Interstate, NINHS, State Primary routes = 5 years (2007-2011), minimum 5 crashes. 

State Secondary routes = 10 years (2002-2011), minimum 5 crashes. 

State Urban routes = 3 years (2009-2011), minimum 5 crashes. 

Severe Injuries (SINJ) – any combination of Fatal or Severe Injuries meeting meeting the following criteria: 

 

Interstate, NINHS, State Primary routes = 5 years (2007-2011), minimum 4 crashes 

State Secondary routes = 10 years (2002-2011), minimum 4 crashes 
2013 Montana Highway Safety Improvement Program

11

State Urban routes = 3 years (2009-2011), minimum 5 crashes

Intersection (INTX) – Rural, In Intersection or Intersection Related only, Severity > “0” meeting the following criteria: 

 

NINHS, State Primary, State Secondary = 5 years (2007-2011), minimum 4 crashes 

Commercial Vehicles (CV) – Rural, Severity > “0” meeting the following criteria: 

 

NINHS, State Primary, State Secondary = 10 years (2002-2011), minimum 4 crashes 

Local Roads (LR) – Rural, Severity > “0” meeting the following criteria: 

 

Off System (Location Type = ‘R’) = 10 years (2002-2011), minimum 4 crashes in a section.

Requests (REQ) - Areas to be investigated as requested by an agency or individual. 

Once the sites are identified, a preliminary office review identifies the sites where there are near-term reconstruction 

projects, currently programmed safety projects, or sites that were recently field reviewed. After drafting collision 

diagrams, an office review establishes the sites that need on site field reviews. The sites showing no crash trend are 

not field reviewed. The field review team establishes crash causations and contributing factors. The team members 

debate potential countermeasures. Conceptual designs are developed with cost estimates. 

The project prioritization process is based on a benefit-cost analysis. The costs are the annualized cost of 

construction over the service life of the proposed improvement plus the annual increase in operation and 

maintenance costs due to the improvement on the basis of the costs of the analysis year. The benefits are the 

anticipated annualized cost reductions due to a lower number of crashes and lower crash severity in the given 

analysis year. The projects with the highest benefit-cost ratios get programmed for improvements.

MDT has initiated several district wide horizontal curve signing upgrade projects. The intent of these projects is to 

complete a proactive improvement to upgrade all the curve warning signs to a consistent standard. This project 

directly addresses one of the strategies outlined in the Montana Comprehensive Highway Safety Plan (CHSP).

MDT has finalized guidelines for conducting Road Safety audits (RSA) and has completed two RSA’s in the last year. 

MDT is also evaluating the existing roadway network to identify locations for construction of shoulder rumble strips 

and has nominated several standalone rumble strip projects. These projects are proactive efforts to address the 

Single Vehicle Run-Off-the-Road emphasis area within the CHSP.

MDT has nominated several projects to install retroreflective borders on the signals as well as upgrading to flashing 

yellow arrows at select locations. Finally, MDT has also nominated several projects to upgrade all the “wrong-way” 

signing on the interstate off ramps.

The following definitions/notes are provided for clarification of the crash criteria utilized in development of the HSIP.

Crash Rate: Number of crashes per million vehicles miles.

Severity Index: Ratio of the sum of fatal and incapacitating injury crashes times 8 plus the number of other injury 

crashes times 3 plus the number of property damage crashes to the total number of crashes.
2013 Montana Highway Safety Improvement Program

12

Severity Rate: Crash rate multiplied by the severity index.

Urban Routes: Searches crashes coded to the state Urban Route with the majority being between City and Urban 

Limits. Crashes within city limits on Urban Routes should be coded to city grid. Some crashes outside city limits may 

be coded to city grid or range, township, section, which will not show in the queried criteria.

Describe any other aspects of the general Highway Safety Improvement Program implementation 

progress on which you would like to elaborate.

Historically, MDT has been very successful in utilizing HSIP funds. We are evaluating our current project nomination guidelines 

in an effort to blend the historical focus on site specific projects with proactive/systemic/systematic projects as well as 

improvements recommended in Road Safety audits. Completion of updated guidelines will likely be completed once the new 

upgrade to the safety analysis system is complete.

In line with the Comprehensive Highway Safety Plan (CHSP), Montana identified rural high crash severity corridors in terms of

corridors with high crash severity, the corridors with high number of unbelted vehicle occupants involved in severe crashes and 

corridors with high incidents of drivers who had been using alcohol or drugs and who were involved in severe crashes. The 

mileage identified for these corridors represents the roadways carrying the highest traffic volumes and experiencing the highest 

numbers of severe crashes.

MDT also identified corridors with a combination of high crash severity rate and high number of fatalities and incapacitating

injuries per mile. The corridors with the highest severity rates using a 10 mile plus segment length were identified as well as the 

corridors with the highest number of severe crashes (fatal and incapacitating injury crashes). MDT added the crash severity rate 

and the number of fatalities and incapacitating injuries per mile to derive the high crash severity corridors. MDT has updated the 

high crash severity corridors with 2011 crash data. A map of the currently identified corridors is available on the MDT internet 

page at: http://www.mdt.mt.gov/safety/safety-initiatives/high-crash-corridors.shtml.

MDT has a process to perform road (corridor) safety audits of these corridors. The intent is to develop safety recommendations as 

the engineering component of this process and pursue strategies such as enforcement activities and public education, involving 

the disciplines of the participants in the development of the strategic highway safety plan. The road safety audits recommend

short, medium and long term improvements from a behavioral and engineering perspective.
2013 Montana Highway Safety Improvement Program

15

MDT has also initiated development of a Roadway Departure Safety Implementation Plan. The purpose of this Plan is to provide 

specific details on countermeasures, actions, key steps, schedules, and investments needed to support the goals of the CHSP by 

mitigating roadway departure crashes. The plan will provide specific information on how additions, modifications or 

enhancements to the current programs can be effectively implemented to address these types of crashes. 

MDT is also developing a non-infrastructure HSIP project. The goal of the project is the development of a media campaign to 

educate drivers on road departure crashes. 

Based on high numbers of crashes involving drivers who had been using alcohol or drugs and high numbers of crashes with 

occupants not wearing their seat belt, the Montana Highway Patrol in collaboration with MDT established corridors where roving 

patrol are performing concentrated enforcement.

Similarly, based on number of crashes in the Motor Carrier Services crash data base, corridors were selected for increased 

enforcement and truck safety checks.

Enforcement (selective) has been concentrated in most of these corridors, under NHTSA Grants. Most of the education 

campaigns will be statewide. Emergency Medical Services and Trauma Services Section provide intervention strategies with 

patients involved in alcohol/drug related crashes and have formed regional task forces promoting a reduction of trauma.

Describe any other aspects of the general highway safety trends on which you would like to elaborate.

At the initiation of the Montana Comprehensive Highway Safety Plan (CHSP) planning process 

in 2005, the State of Montana adopted an overall “vision” for the CHSP to establish a unifying 

focus for the ensuing safety planning effort: “All highway users in Montana arrive safely at their 

destinations.” Based on the State’s transportation safety trends, the CHSP Oversight Committee 

reassessed the goal of the CHSP in 2009. The revised goal of the Montana CHSP is: “To reduce 

fatalities and incapacitating injuries in the State of Montana by half in two decades, from 1,704 

in 2007 to 852 by 2030.” No highway fatalities are acceptable and all are preventable. Yet 

realistically, no state has been successful in achieving zero highway fatalities. The original goal 

of the Montana CHSP was based on the national safety goal adopted by the American 

Association of State Highway and Transportation Officials (AASHTO) in 2005.

Given national trends which indicated that AASHTO’s initial national fatality rate goal of 1.0 

could not be met in 2008, AASHTO revised its national fatality goal in 2007. The AASHTO goal is 

now to halve fatalities over the next two decades by reducing national fatalities by 1,000 per 

year. The AASHTO policy resolution establishing the new goal “recognizes that success in 

implementing an aggressive highway safety goal is based in large part upon wide acceptance 

and enthusiastic support by the general public, media, and public/private institutions of 

highway safety goals” and “the statement of a safety goal in terms of actual number of lives 

saved will resonate with the public and these institutions significantly more than the abstract 

notion of an exposure rate measure.” In short, AASHTO is advocating an aggressive but 

supportable goal based on actual fatalities, rather than rates.

Consistent with AASHTO’s approach to utilize actual numbers to define its national 

transportation safety goal and to halve fatalities over the next two decades, Montana has 

adopted a similar goal. However, given Montana’s lower overall fatality statistics and the 

tendency for these smaller numbers to fluctuate more substantially from year to year, 

Montana’s CHSP Amendment goal also takes serious injuries (i.e., incapacitating injuries) into 

account as a basis for establishing a more consistent trend. The CHSP goal cited above would 

not only result in a substantial reduction in the State’s highway fatalities and serious injuries, it 

also would support Montana’s proportional contribution to AASHTO’s national goal. Assuming a 

base year of 2007 in which Montana experienced 1,704 highway fatalities and serious injuries, 

halving the State’s severe injuries by 2030 would result in 852 fatalities and serious injuries by 

2030, or an average reduction of 42.6 fatalities and serious injuries per year.

The 2013 Annual Transportation Safety Meeting will be held on October 15-18. Participants 

represented will include a wide variety of organizations and agencies addressing the four E’s of 

transportation safety (Education, Enforcement, Engineering, and Emergency Response). This 

will be the seventh annual meeting since the implementation of the Comprehensive Highway 

Safety Plan (CHSP) began in 2006. It is also the first time the annual meeting will be held in the 

fall of the year. 

The overall goal of the CHSP is to reduce fatalities and incapacitating injuries in the State of 

Montana by half in two decades, from 1,704 in 2007 to 852 by 2030. The following is summary 

of the number of fatalities and serious injuries from 2006-2012:

Year

and

Serious 

Injuries 

2006 1,877

2007 1,704

2008 1,565

2009 1,322

2010 1,185

2011 1,162

2012 1,335

Additionally, in 2012 the number of fatalities decreased by 4 (-1.9%) from 209 in 2011 to 205 in 

2012; however, severe injuries increased by 174 (18.2%) from 956 in 2011 to 1,130 in 2012.

*Performance measure data is presented using a five-year rolling average.

The Montana Department of Transportation (MDT) queried the crash database for crashes in 

which the driver is 65 years of age and older for 2004-2012 time frame. A summary of the 

crash severity and number of persons injured (based on severity) in the crash were tabulated. 

For reporting purposes, the State of Montana only looked at the crashes that resulted in a fatal 

injury or serious (incapacitating) injury. The fatal injury crash data was obtained by querying the 

Fatality Analysis Reporting System (FARS) database. The criteria used for querying the FARS 

database was as follows: 

1) Select State: Montana

2) Number of Fatalities In Crash: All

3) Age: 65 years – 97 years older & 100 years

4) Person Type: Driver of a Motor Vehicle In-Transport and/or Pedestrian

The population data was obtained from Attachment 2 of the Older Driver and Pedestrian 

Special Rule Interim Guidance (February 13, 2013) provided by the FHWA. Because 2012 

population data is not provided in the interim guidance, calculation of corresponding rates for 

2012 was not completed.

MDT then used a 5-year rolling average for each year of reporting (i.e. 2009, 2010, and 2011).

A similar query was run for crashes involving a pedestrian(s) that were 65 years of age and 

older for the same time period and 5-year rolling average was calculated. 

To derive the fatality rate and serious injury rate for persons 65 years of age or older per 1,000 

total population that are age 65 or greater, the number of fatalities and serious injuries were 

added together for each year of study and divided by the proportion of Montana’s population 

that is 65 years of age and older for the corresponding year obtained from Attachment 2. As 
2013 Montana Highway Safety Improvement Program

61

mentioned above, once the yearly fatality rates and serious injury rates were calculated a 5-

year rolling average was used for 2008-2011 reporting years. 

An example calculation for the combined Fatal and Serious Injury Rate per capita for Drivers 

and Pedestrians 65 years of age and older for 2011 (2011, 2010, 2009, 2008, and 2007) is 

illustrated below:

(Fatal + Serious Injury 2011 Drivers and Pedestrians 65 years of age and older/2011 Population 

Figure)+ (Fatal + Serious Injury 2010 Drivers and Pedestrians 65 years of age and older/2011 

Population Figure)+ (Fatal + Serious Injury 2009 Drivers and Pedestrians 65 years of age and 

older/2011 Population Figure)+ (Fatal + Serious Injury 2008 Drivers and Pedestrians 65 years of 

age and older/2011 Population Figure)+ (Fatal + Serious Injury 2007 Drivers and Pedestrians 65 

years of age and older/2011 Population Figure)/5

The same methodology was used for calculating the Fatality Rate and/or Serious Injury Rate by 

excluding either the fatal or serious injury portion of the above equation.

The Montana Department of Transportation used the calculation methodology described in the 

Section 142-Older Drivers and Pedestrians Special Rule Interim Guidance Report dated February 

13, 2013.

The current version of the Montana Comprehensive Highway Safety Plan (CHSP) includes an 

emphasis area for older driver crashes. The performance measure established for this 

emphasis area by the CHSP stakeholders during the 2012 annual meeting was to reduce the 

five-year average number of fatalities and incapacitating injuries from crashes involving older 

drivers from 209 in 2010 to 162 by 2015. Additional detail on the Older Driver Emphasis Area 

and the strategies can be found on the MDT internet site at:

Since the establishment of the overall Comprehensive Highway Safety Plan goal in 2009 Montana has achieved a significant reduction in fatalities and 

incapacitating injuries from 1,704 in 2007 to 1,335 in 2012, nearly a 22% decrease. 

The Highway Safety Improvement Program (HSIP) is a component of the overall Comprehensive Highway Safety Plan and has contributed to this statewide

reduction in severe crashes. MDT’s site specific (hot-spot) program mitigates crashes at specific locations using proven engineering countermeasures. MDT has 

historically utilized all available HSIP funding to construct safety improvements on Montana’s highways.

The Montana Comprehensive Highway Safety Plan (CHSP) has several emphasis areas which include a significant engineering strategy and directly relate to the 

HSIP. These emphasis areas include: 1) Reducing Single-Vehicle-Run-Off-the- Road Crashes; and 2) Reducing Crashes in High Crash Corridors/High Crash 

Locations. The majority of fatalities in Montana, nearly 60 percent, continue to be the result of single vehicle run-off-the-road crashes (SVROR). Factors 

contributing to single-vehicle run-off-the-road crashes frequently involve behavior issues that are being addressed in other CHSP Emphasis Areas such as 

passenger restraint, impairment, and young drivers. 
2013 Montana Highway Safety Improvement Program

72

The SVROR Emphasis Area team is currently looking into experiences and strategies that have been tried in other states for applicability to Montana. The 

following performance measure target was established during the 2012 Annual Meeting: Reduce the five-year average number of fatalities and incapacitating 

injuries of single vehicle, run-off-the-road crashes from 817 in 2010 to 632 by 2015. 

The chart attached to this question presents the 5-year rolling average crash information for single vehicle run off the road fatalities and incapacitating injuries. As 

shown, the 5-year average number of fatalities and serious injuries has decreased steadily over time.

MDT has initiated district wide horizontal curve signing upgrade projects. These projects address the High Crash Corridor (HCC) 

Emphasis Area, Strategy HC-3 HCC Sign Evaluation in the CHSP. In addition, these projects will address single vehicle run off the road 

crashes and high crash corridors/high crash locations, both of which are identified emphasis areas in the CHSP. Long term, the intent 

of these projects is to evaluate all MDT roadways; however, evaluations will likely begin on the HCC’s identified in the CHSP. Projects 

are on-going in the Missoula District and will be starting shortly in the Great Falls, Butte and Billings Districts. With the adoption of 

the new MUTCD, MDT is required to update all horizontal curve signage by 2019. This proposed project furthers the goals of the 

CHSP as well as meets the deadlines established in the MUTCD. The projects are currently in the development phase and have not 

been constructed. Evaluations of the effectiveness of the projects can be completed once the projects are constructed and 

sufficient after period data is available. 
2013 Montana Highway Safety Improvement Program

85

MDT has also initiated system wide projects on the interstate system to upgrade all of the "wrong way" signing to MUTCD 

standards. The first project in the Missoula District is currently slated for construction in federal fiscal year 2014.

Several stand alone rumble strip projects (centerline and shoulder) were identified and advanced as part of this year's HSIP. These 

projects directly address the Single Vehicle Run Off the Road Emphasis area in the CHSP.

MDT has elected to evaluate the HSIP based on groups of similar projects on an annual basis. At this time, the evaluation process 

will focus on nominated projects having a construction and construction engineering (CN+CE) cost exceeding $100,000. Smaller, 

lower cost projects (CN + CE < $100,000) will not be included in the initial evaluations; however, as the evaluation process matures 

consideration will be given to evaluating these smaller improvements. Additional evaluations or site specific evaluations will be 

completed on a case-by-case basis. Typically, a minimum of 5-years of after data should be available for the treatment sites. For 

urban improvements, utilization of a 3-year before and after time period can be considered.
