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 also 

completed or has initiated 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 our safety analysis software and is developing a 

Roadway Departure Implementation Plan (RDIP). The RDIP included the development of Safety 

Performance Functions (SPFs) and diagnostic norms for all rural, on-system roads for both total crashes 

as well as road departure crashes. This report and the associated tools will likely be used in future years 

for identification of projects thru the HSIP.

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 decrease in 2013 as compared to 2012; 

however, overall fatalities and serious injuries are down over 21% since the establishment of the goal in 

2007. MDT continues efforts to conduct outreach to local government agencies on the availability of 

HSIP 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 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. 

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 attached to this report (HSIPAPPLICATION 2010.pdf) and is also included on the MDT internet page at: 

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

During the past year, MDT presented information on the HSIP at the annual meeting of the Montana 

Association of County Road Supervisors, the Joint Engineers Conference, and the League of Cities and 

Towns annual meeting. These meetings were attended by local representatives with an interest in local 

road safety.

Briefly describe coordination with internal partners. 

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

Highway Safety Plan (CHSP). The CHSP is currently undergoing an update which will be completed in 

2015.

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.

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 
2014 Montana Highway Safety Improvement Program

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.

During the reporting period MDT selected a vendor for an upgrade to the safety database and analysis 

tools. This new software, referred to as the Safety Information Management System (SIMS), has been 

deployed at MDT. MDT personnel are currently in the testing and final configuration phase of the 

project. This new system will allow 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 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. Additionally, in the past year MDT has worked with MHP to gain access to the 

MHP citation data. 

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

Safety is taking the lead in the areas of road departure crashes and in the rural high-crash severity 

corridors and high crash locations. MDT is conducting a minimum of two CSA's per year.

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 potential locations for the 2014 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 = 10 years (2003-2012), minimum 5 crashes.

State Primary routes = 10 years (2003-2012), minimum 5 crashes.(3.34)

State Secondary routes = 10 years (2003-2012), minimum 5 crashes. 

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

criteria: 

Interstate, NINHS, State Primary routes = 10 years (2003-2012), minimum 5 crashes. 

State Secondary routes = 10 years (2003-2012), minimum 5 crashes. 

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

criteria: 

Interstate, NINHS, State Primary routes = 10 years (2003-2012), minimum 5 crashes 

State Secondary routes = 10 years (2003-2012), minimum 5 crashes 
2014 Montana Highway Safety Improvement Program

11

Intersection (INTX) – Rural, In Intersection or Intersection Related only, Severity – all crashes

NINHS, State Primary, State Secondary = 10 years (2003-2012), minimum 5 crashes

Commercial Vehicles (CV) – Rural, Severity – all crashes meeting the following 

criteria: 

NINHS, State Primary, State Secondary = 10 years (2003-2012), minimum 5 crashes

Pedestrian Crashes (PED) – Severity – all crashes 

NINHS, State Primary, State Secondary = 10 years (2003-2012), minimum 3 crashes

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 CHSP.

MDT has finalized guidelines for conducting CSA's and has completed one CSA in the last year with 

another anticipated for completion by the end of 2014. 

MDT has also initiated development of a Roadway Departure Implementation Plan. This plan includes 

development of Safety Performance Functions (SPFs), Level of Service of Safety (LOSS), and diagnostic 

norms for rural on-system routes. MDT anticipates using this information for development of the HSIP 

in coming years. As part of the Plan, 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.
2014 Montana Highway Safety Improvement Program

MDT is also developing SPF's and diagnostic norms for intersections. Completion of this project is 

anticipated in 2015. 

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.

Severity Rate: Crash rate multiplied by the severity index.

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 CSA's. Completion of 

updated HSIP guidelines will be initiated once the new upgrade to the safety analysis system is 

complete.

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 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. Final completion of the plan 

is anticipated for the fall of 2014. 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.

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

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 -- 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

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. Currently, the Montana CHSP is being updated. Completion of the CHSP update is 

anticipated in 2015.

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

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 2005-2013 time frame.

A summary of the 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 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

Interim Guidance (February 13, 2013) provided by the FHWA. Because 2013 population data is not 

provided in the interim guidance and 2013 fatality information is not available in FARS, calculation of 

corresponding rates for 2013 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 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: 
2014 Montana Highway Safety Improvement Program

(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.

Since the establishment of the current overall CHSP goal in 2009 Montana has achieved a significant reduction in fatalities and incapacitating 

injuries from 1,704 in 2007 to 1,331 in 2013, nearly a 22% decrease. The HSIP is a component of the overall CHSP 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.

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 road departure 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. Data has been collected statewide. Projects are on-going in the 

Missoula and Butte 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 Missoula District project was let in 

the summer of 2014. Evaluations of the effectiveness of the projects can be completed once the projects are constructed and sufficient after 

period data is available.

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

projects are planned to be let for construction in federal fiscal year 2014. Several projects have been nominated to upgrade advanced warning 

signage/flashers in advance of traffic signals to ensure statewide consistency.
