2. Executive Summary

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

allotted Highway Safety Improvement Program (HSIP) funds on Montana's roadways. MDT actively 

utilized our new safety analysis software and database as well as the results of our Roadway Departure 

Study (RDS), including utilization of Safety Performance Functions (SPFs) and diagnostic norms for 

identification of potential locations for safety improvements. 

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 totals 

for fatalities and severe injuries in the state were up over 5% in 2015 as compared to 2014; however, 

overall fatalities and serious injuries are down over 28% since 2007. MDT continues efforts to conduct 

outreach to local government agencies on the availability of HSIP funds for completion of safety 

improvements on local roads.

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 MAP21 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.

Program Administration

3. How are Highway Safety Improvement Program funds administered in the State? 

Central

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

All crashes investigated by the Montana Highway Patrol, or submitted to the MHP by a local 

enforcement agency, are available to MDT. In 2014 MDT implemented a new crash database system.

This system allows MDT staff to query local road crash data by route and reference post as well as 

spatially via GIS tools. Fatal crash data is available for the Tribal reservations; however, other crashes 

investigated by the Tribal enforcement agencies or Bureau of Indian Affairs 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 included on the MDT internet page at: 

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

Potential HSIP projects on local and Tribal roads are currently evaluated using the same methodologies 

as are applied to potential projects on the state owned system.

6. Briefly describe coordination with internal partners. 

The MDT Planning Division coordinates the safety activities and administers the Comprehensive 

Highway Safety Plan (CHSP). The CHSP has recently undergone an update. The CHSP update was 

completed in May 2015. The updated CHSP is available at:

http://www.mdt.mt.gov/publications/docs/plans/chsp/current_chsp.pdf 

The Highway Safety Improvement Program is administered centrally by the MDT Traffic and Safety 

Bureau. Crash clusters are identified by roadway system and by various criteria. 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 CHSP. 

Appropriate entities within MDT are invited to participate in Corridor Safety Audits (CSA's). These 

entities include, but may not be limited to, the State Highway Traffic Safety Section, Planning Division, 

Motor Carrier Services, Road Design, Traffic Operations, Maintenance, and District personnel.

7. Identify which external partners are involved with Highway Safety Improvement Program planning. 

Metropolitan Planning Organizations

Local Government Association

Other-Tribes

Other-Law Enforcement

8. Identify any program administration practices used to implement the HSIP that have changed since 

the last reporting period.

Other-No changes in the reporting period.

9. 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 
2016 Montana Highway Safety Improvement Program

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 has 

been developed and is being used by several local agencies. This web based system allows 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.

In 2014, MDT implemented an upgrade to the safety database and analysis tools. This new software, 

referred to as the Safety Information Management System (SIMS), has been deployed and is now in 

production at MDT. This new system allows MDT to access the MMUCC compliant crash data being 

collected by the Montana Highway Patrol. The SIMS system also has access to many roadway data 

elements including many of the Fundamental Data Elements identified by FHWA. Additionally, MDT has 

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

The new system also allowed MDT to begin utilizing MHP citation data. 

The Traffic and Safety Bureau is actively involved in the implementation and update of the CHSP. Traffic 

and Safety is taking the lead in the areas of road departure crashes and intersection crashes.

14. Identify any program methodology practices used to implement the HSIP that have changed since 

the last reporting period.

Other-No Changes

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

you would like to elaborate. 

To identify potential location for development of the 2016 HSIP, MDT has elected to screen the network 

using the following initial criteria: 1) Tree crash patterns; 2) Domestic animal crash patterns; 3) Wet 

road plus injury crash patterns; 4) Overturn plus injury crash patterns; 5) Overturn crash patterns 

on secondary roads; 6) Road departure crashes occurring in dark conditions; 7) Requested Sites (By an 

Agency, District, Public Citizen, Safety Section). 

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 the preliminary office review, further 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. The benefits are the anticipated annualized cost 

reductions due to a lower number of crashes and lower crash severity. The projects with the highest 

benefit-cost ratios are nominated 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. MDT also completed a systemic wrong way signing upgrade to all interstate ramps. The intent 

of this project was to bring the signing for all off-ramps to a consistent standard. 

MDT has also completed development of a Roadway Departure Study. This study included development 

of Safety Performance Functions (SPFs), Level of Service of Safety (LOSS), and diagnostic norms for rural 

on-system routes. MDT is using these tools and methodologies for evaluation of the HSIP as well as 

analysis of other agency projects. As part of the Study, MDT has begun nominating centerline rumble 

strip projects as a proactive effort to address head-on, sideswipe opposite direction, and run off the 

road left crashes. MDT is also developing SPF's and diagnostic norms for intersections. Completion of 

this project is anticipated in 2016/2017.

None at this time.

22. 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. MDT is initiating the development of a 

Montana specific HSIP manual that will describe the overall processes for the planning, implementation, 

and evaluation of the HSIP components; as well as the processes MDT is using to evaluate and 

implement safety measures as part of overall project development. Initiation of this project is 

scheduled for summer/fall of 2016.

MDT has a process to perform CSA's on selected 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 CSA's recommend short, medium and long term 

improvements from a behavioral and engineering perspective. 

MDT has also completed development of a Roadway Departure Study. This study included development 

of Safety Performance Functions (SPFs), Level of Service of Safety (LOSS), and diagnostic norms for rural 

on-system routes. MDT is using these tools and methodologies for development of the HSIP as well as 

analysis of other agency projects. As part of the Study, MDT has begun nominating centerline rumble 

strip projects as a proactive effort to address head-on, sideswipe opposite direction, and run off the 

road left crashes. MDT is also developing SPF's and diagnostic norms for intersections. Completion of 

this project is anticipated in 2016/2017.

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

elaborate.

In the spring of 2014, Montana Department of Transportation Director Mike Tooley announced “Vision 

Zero,” a multi-pronged initiative with the ultimate goal of eliminating deaths and injuries on Montana 

highways. Montana Highway Safety Stakeholders completed an update of the Montana CHSP in the 

spring of 2015. The updated CHSP formalizes Montana's vision of zero deaths and serious injuries on 

Montana's roads. 

While the overall goal of the CHSP is zero fatalities and serious injuries, the CHSP update maintains an 

interim goal of halving fatalities and serious injuries from 1,705 in 2007 to 852 in 2030. The following is 

summary of the number of fatalities and serious injuries from 2006-2015: 

Year -- Fatalities and Serious Injuries 

2006 -- 1,877 

2007 -- 1,704 

2008 -- 1,565 

2009 -- 1,322 

2010 -- 1,185 

2011 -- 1,162 

2012 -- 1,335 

2013 -- 1,331 

2014 -- 1,158

2015 -- 1,224

In order to determine the per capita fatality and serious injury rates the Montana Department of 

Transportation (MDT) queried the MDT crash database for crashes in which the driver or pedestrian 

involved is 65 years of age and older for 2006-2014 time frame. 

A summary of the number of drivers or pedestrians 65 years of age or older who were injured (based on 

severity) in the crash were tabulated. For reporting purposes, the State of Montana only evaluated 

crashes that resulted in a fatal injury or serious (incapacitating) injury to the older driver or pedestrian.

Other occupants in the crash are not included in the calculation.

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) Injury Severity: Fatal Injury 

3) Age: 65 years or older 

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 

Final Guidance (May 19, 2016) provided by the FHWA. 

MDT then used a 5-year rolling average for each year of reporting. 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 mentioned above, once the yearly 

fatality rates and serious injury rates were calculated a 5-year rolling average was used for the various 

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)+

Glossary

5 year rolling average means the average of five individual, consecutive annual points of data (e.g. 

annual fatality rate).

Emphasis area means a highway safety priority in a State’s SHSP, identified through a data-driven, 

collaborative process. 

Highway safety improvement project means strategies, activities and projects on a public road that are 

consistent with a State strategic highway safety plan and corrects or improves a hazardous road location 

or feature or addresses a highway safety problem. 

HMVMT means hundred million vehicle miles traveled.

Non-infrastructure projects are projects that do not result in construction. Examples of noninfrastructure projects include road safety audits, transportation safety planning activities, 

improvements in the collection and analysis of data, education and outreach, and enforcement 

activities.

Older driver special rule applies if traffic fatalities and serious injuries per capita for drivers and 

pedestrians over the age of 65 in a State increases during the most recent 2-year period for which data 

are available, as defined in the Older Driver and Pedestrian Special Rule Interim Guidance dated 

February 13, 2013. 

Performance measure means indicators that enable decision-makers and other stakeholders to monitor 

changes in system condition and performance against established visions, goals, and objectives.

Programmed funds mean those funds that have been programmed in the Statewide Transportation 

Improvement Program (STIP) to be expended on highway safety improvement projects.

Roadway Functional Classification means the process by which streets and highways are grouped into
