Executive Summary

The Montana Department of Transportation continues to successfully implement Highway Safety Improvement 

Program (HSIP) Funds throughout the State. This past year, funds were utilized on state, county, city and local 

roadways. This included large systemic applications (curve signing, centerline rumble strips, median cable 

barrier) as well as spot locations. The spot safety improvements ranged from delineation and signs to turn 

lanes, signals and roundabouts. 

MDT's Safety Information Management System (SIMS) and Montana Specific Safety Performance Functions 

continues to provide Montana with effective tools to identify, analyze and implement HSIP projects. 

Severe crash injury numbers continue to decline. Severe crash types are defined as fatalities and serious 

injuries. Although fatalities saw a slight increase of 2, serious injuries saw a decrease of nearly 10%. Over the 

past 3 years, fatalities have remained fairly consistent in the low to mid 180's, while the number of serious 

injuries is the lowest it's been in 9 years.

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 Reporting Guidance dated 

December 29, 2016 and consists of five sections: program structure, progress in implementing highway safety 

improvement projects, progress in achieving safety outcomes and performance targets, effectiveness of the 

improvements and compliance assessment. 

Program Structure

Program Administration 

Describe the general structure of the HSIP in the State. 

The Safety Engineering Section within the Traffic & Safety Bureau, administers MDT's HSIP Program. 

Each year, the Safety Engineering Section uses a data-driven approach to identify locations for potential safety 

improvements. This includes spot locations and also longer highway segments or entire corridors for systemic 

safety improvements. Sites are then reviewed through an established process which includes reviewing 

Montana Highway Patrol crash records, completing an office review and usually a field review. The last step is 

completing a benefit cost for a potential safety countermeasure that addresses the identified crash trend. The 

sites that meet the minimum benefit cost threshold established by FHWA and are within the HSIP available 

funding, are nominated as HSIP Funded Safety Projects. 

Where is HSIP staff located within the State DOT? 

 Engineering

As noted above in Question #3, the Safety Engineering Section administers MDT's HSIP Program. MDT's 

program is a centrally administered program within MDT's Headquarters Office. 

How are HSIP funds allocated in a State? 

• Central Office via Statewide Competitive Application Process 

MDT's HSIP Funds are administered through MDT Headquarters. However, significant coordination takes 

place with MDT's District Staff and other government entities to develop Montana's annual HSIP List of 

Projects. Other government entities include the Montana Highway Patrol and Local Government Staff. 

Describe how local and tribal roads are addressed as part of HSIP. 

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

enforcement agency, are available to MDT. MDT's database and program allows MDT staff the ability 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 
2020 Montana Highway Safety Improvement Program

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 . These governments may also work 

through MDT's District Offices to request a location be reviewed by MDT's Safety Program.

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. For future HSIP projects, other data-driven tools are 

being developed to assist with identifying potential projects on the local and Tribal roads. These tools are 

anticipated to be usable in late 2020/early 2021. 

Identify which internal partners (e.g., State departments of transportation (DOTs) 

Bureaus, Divisions) are involved with HSIP planning. 

• Design 

• Districts/Regions 

• Governors Highway Safety Office 

• Maintenance 

• Operations 

• Planning 

• Traffic Engineering/Safety 

• Other-Motor Carriers 

Describe coordination with internal partners. 

The MDT Planning Division administers the Comprehensive Highway Safety Plan (CHSP) and Highway Safety 

Plan while MDT's Engineering Division manages the HSIP Program. There is significant coordination between 

the two Divisions and their corresponding CHSP Emphasis Areas. In addition, both Divisions are represented 

on the Traffic Records Coordinating Committee (TRCC). MDT's CHSP is currently being updated and 

coordination for that Plan will continue to be required between the two Divisions. The CHSP's last update was 

completed in May 2015. This new update is anticipated to be completed in late 2020. The most current CHSP 

is available at: http://www.mdt.mt.gov/visionzero/docs/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. Coordination with MDT's District Staff, 

Environmental Staff, Maintenance and other engineering disciplines is on-going with the program. This takes 

place as sites are analyzed and as projects are identified, designed and constructed. 

Identify which external partners are involved with HSIP planning. 

• Local Government Agency 

• Regional Planning Organizations (e.g. MPOs, RPOs, COGs) 

• Other-Tribes 

• Other-Law Enforcement 

Describe coordination with external partners. 

MDT routinely receives requests for specific sites identified for review from law enforcement, local government 

entities and tribal governments. MDT coordinates with these governments during the field review process to 

gather additional input for addressing the crash trends. MDT coordinates with the MPO's in the same manner; 

however, the coordination is done through MDT's District and Planning Division Offices rather than the Traffic 

and Safety Bureau. 
2020 Montana Highway Safety Improvement Program

Page 7 of 60

Describe other aspects of HSIP Administration on which the State 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 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. MDT is currently in the process of updating this system. This is anticipated 

to be complete in early 2021. 

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

Safety continues to take the lead in the areas of roadway departure crashes and intersection crashes.

• Cable Median Barriers 

• Horizontal curve signs 
2020 Montana Highway Safety Improvement Program

Page 12 of 60

• Rumble Strips 

MDT recently completed a systemic application of curve warning signs across the 5 MDT Districts. MDT is also 

completing the final District centerline rumble strip installation. Future systemic applications include high 

tension median cable rail on the interstate system. 

What process is used to identify potential countermeasures? 

• Crash data analysis 

• Data-driven safety analysis tools (HSM, CMF Clearinghouse, SafetyAnalyst, usRAP) 

• Engineering Study 

• Road Safety Assessment 

• SHSP/Local road safety plan 

Does the State HSIP consider connected vehicles and ITS technologies? 

No

As these technologies continue to evolve, the HSIP program may consider appropriate applications to address 

safety on Montana's roadways. However, at this time, the HSIP Program doesn't consider these technologies. 

Does the State use the Highway Safety Manual to support HSIP efforts? 

Yes 

Please describe how the State uses the HSM to support HSIP efforts. 

MDT developed both its Roadway Departure Study and Intersection Safety Study using Montana specific 

Safety Performance Functions (SPF) and Levels of Service of Safety (LOSS). These SPF's and LOSS's were 

developed based on methodologies in the Highway Safety Manual. 

Describe other aspects of the HSIP methodology on which the State would like to 

elaborate. 

To identify potential locations for the 2020 HSIP, criteria is still being developed. Criteria will include roadway 

departure and/or intersection crashes which is in line with Montana's Comprehensive Highway Safety Plan. 

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 state-wide systemic projects including horizontal curve signing, interstate wrong-way 

signing upgrades and centerline rumble strips. These three projects are being installed on a large district-wide 

scale and are nearly installation completion. MDT is also looking at other large scale systemic projects 

including interstate median barrier and developing local road safety plans.

MDT recently updated their Roadway Departure Safety Performance Functions (SPFs), Levels of Service of 

Safety (LOSS), and diagnostic norms. MDT will begin using the updated tools for continued evaluation of the 

HSIP as well as analysis of other agency projects.

has a ongoing research project in conjunction with Montana's Local Technical Assistant Program (LTAP) Office 

and the Western Transportation Institute at Montana State University. The research project titled " Developing 

a Methodology for Implementing Safety Improvements on Low-Volume Roads in Montana" and completion is 

anticipated in late 2020.

0%

Discuss impediments to obligating HSIP funds and plans to overcome this challenge in 

the future.

The inability to utilize HSIP funding for non-infrastructure projects impedes MDT's HSIP Program. NHTSA has 

determined that 94% of crashes can be tied back to human error or bad decisions. By only focusing on 

infrastructure improvements, we are focusing on mitigating the result of the crash but not necessarily the 

contributing human factor cause to the crash (drinking, cell-phone usage, inattentiveness, distraction, occupant 

protection, etc). In order to move towards Vision Zero, drivers need continued awareness of their actions and 

how these actions are contributing to vehicular crashes.

In addition, MDT is required to participate in fall and spring media campaigns for occupant protection and seat 

belts. There is no additional funding available to provide media at other times of the year. However, Montana 

experiences its highest number of fatalities during the summer months and MDT has no active campaign 

during that time period. 

Describe any other aspects of the State’s progress in implementing HSIP projects on 

which the State would like to elaborate. 

Historically, MDT has been very successful in utilizing HSIP Funds and has strong support for the program 

from MDT Management. MDT is utilizing recently completed studies to identify locations for safety 

improvements. These studies include the Median Cable Barrier Study, the Intersection Safety Study and the 

Roadway Departure Study (2020 Update). These studies use data-driven tools, HSM methodologies and 

Montana specific data to assist MDT in implementing HSIP projects across the state.

Safety Performance Targets

Safety Performance Targets

Calendar Year 2021 Targets *

Number of Fatalities:182.7

Describe the basis for established target, including how it supports SHSP goals.

The 2021 Target is expressed as the 5-year rolling average using historical trends. The methodology was 

updated as part of the 2020 CHSP update process by the Advisory Committee. The target setting methodology 

is as follows: The methodology analyzed historical trend data and considered potential impacts of COVID-19 to 

determine ambitious, yet achievable targets for 2021-2025. Based on a 10-year trend, a moderate reduction of 

3 fatalities per year is the target. This supports the SHSP (known as the Comprehensive Highway Safety Plan 

(CHSP) in Montana) by working towards the overall Vision Zero Goal and an interim safety goal of halving 

fatalities and serious injuries from 1,705 in 2007 to 852 in 2030.

Number of Serious Injuries:652.5

Describe the basis for established target, including how it supports SHSP goals.

is as follows: The methodology analyzed historical trend data and considered potential impacts of COVID-19 to 

determine ambitious, yet achievable targets for 2021-2025. Based on a 10-year trend, a moderate reduction of 

41 suspected serious injuries per year is the target. This supports the SHSP (known as the Comprehensive 

Highway Safety Plan (CHSP) in Montana) by working towards the overall Vision Zero Goal and an interim 

safety goal of halving fatalities and serious injuries from 1,705 in 2007 to 852 in 2030.

Fatality Rate:1.367

Describe the basis for established target, including how it supports SHSP goals.

The 2021 Target is expressed as the 5-year rolling average using historical trends. The methodology was 

updated as part of the 2020 CHSP update process by the Advisory Committee. The target setting methodology 

is as follows: The methodology analyzed historical trend data and considered potential impacts of COVID-19 to 

determine ambitious, yet achievable targets for 2021-2025. Based on a 10-year trend with consideration of 

COVID-19, a conservative reduction of .041 per million vehicle miles traveled (MVMT) per year is the target. 

This supports the SHSP (known as the Comprehensive Highway Safety Plan (CHSP) in Montana) by working 

towards the overall Vision Zero Goal and an interim safety goal of halving fatalities and serious injuries from 

1,705 in 2007 to 852 in 2030.

Serious Injury Rate:5.450

Describe the basis for established target, including how it supports SHSP goals.

The 2021 Target is expressed as the 5-year rolling average using historical trends. The methodology was 

updated as part of the 2020 CHSP update process by the Advisory Committee. The target setting methodology 

is as follows: The methodology analyzed historical trend data and considered potential impacts of COVID-19 to 

determine ambitious, yet achievable targets for 2021-2025. Based on a 3-year trend with consideration of 

COVID-19, a conservative reduction of .114 per MVMT is the target. This supports the SHSP (known as the 

Comprehensive Highway Safety Plan (CHSP) in Montana) by working towards the overall Vision Zero Goal 

and an interim safety goal of halving fatalities and serious injuries from 1,705 in 2007 to 852 in 2030.

Total Number of Non-Motorized Fatalities and Serious Injuries:63.5

Describe the basis for established target, including how it supports SHSP goals.

The 2021 Target is expressed as the 5-year rolling average using historical trends. The methodology was 

updated as part of the 2020 CHSP update process by the Advisory Committee. The target setting methodology 

is as follows: The methodology analyzed historical trend data and considered potential impacts of COVID-19 to 

determine ambitious, yet achievable targets for 2021-2025. Based on 6-year trend, a low moderate reduction 

of 1 non-motorized fatality or suspected serious injury per year is the target. This supports the SHSP (known 

as the Comprehensive Highway Safety Plan (CHSP) in Montana) by working towards the overall Vision Zero 

Goal and an interim safety goal of halving fatalities and serious injuries from 1,705 in 2007 to 852 in 2030.

Describe efforts to coordinate with other stakeholders (e.g. MPOs, SHSO) to establish 

safety performance targets. 

Montana's Safety Performance Target Setting is a collaborative effort. Representatives from MDT Engineering, 

the State's 3 MPO's and the State Highway Traffic Office met in the spring of 2020 to establish the 2021 Safety 

Performance Targets. These targets were then advanced to the CHSP Advisory Committee to vote their 

concurrence.

Does the State want to report additional optional targets? 

No

Describe progress toward meeting the State’s 2019 Safety Performance Targets (based 

on data available at the time of reporting). For each target, include a discussion of any 

reasons for differences in the actual outcomes and targets.

PERFORMANCE MEASURES TARGETS ACTUALS

Number of Fatalities 187.4 193.2

Number of Serious Injuries 892.8 809.0

Fatality Rate 1.462 1.544

Serious Injury Rate 6.968 6.474

Non-Motorized Fatalities and 

Serious Injuries

73.2 68.6

MDT has made significant progress on 3 of the 5 safety targets for 2019. This includes # of serious injuries, 

serious injury rate and non-motorized fatalities and serious injures. 

However, Montana has not made significant progress during the same time period for fatalities and fatality rate. 

In 2019 Montana saw a small increase from 182 to 184 annual fatalities. After 4 years of declining fatalities, 

this was the first fatality increase . One of the challenges for fatal and serious injury crashes is the behavioral 

aspect. Currently HSIP funds are not eligible for non-infrastructure projects. Future flexibility of these funds 

would assist the agency in addressing both infrastructure and behavioral safety needs.

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

• Other-Observational before/after studies 

MDT utilizes observational before/after studies to evaluate the effectiveness of a particular safety improvement 

or groups of improvements. An observational before/after study requires crash data and volume data from both 

before and after the installation of a safety improvement. 

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

evaluation process focuses on nominated projects having a construction and construction engineering 

(CN+CE) cost exceeding $100,000. Additional evaluations or site specific evaluations are completed on a 

case-by-case basis. Typically, a minimum of 5-years of after data is used for the treatment sites. 

The following steps highlight the process for MDT’s annual evaluation of safety improvements. It is not meant 

to be all encompassing and is meant to be a living process. Modifications to the following process will be made 

as additional data sets and analysis tools are available. 

1. Identify completed projects with a construction plus construction engineering (CN+CE) cost of greater 

than $100,000 and which have sufficient crash data following completion of the project.

2. Group the projects completed in the identified year by improvement type. The following project groups 

are identified to guide the evaluation:

3. Geometric improvements at a specific location (curve realignment or shoulder widening as examples); 

4. Slope flattening or elimination of roadside hazards; 

5. Signing, striping and delineation including the installation of warning flashers; 

6. Installation of guardrail; 

Based on the measures of effectiveness selected previously, describe the results of 

the State's program level evaluations. 

This method of program level evaluation is new to MDT with only a few years actual results. With MDT's recent 

Roadway Departure Study and newly implemented Intersection Safety Study, the program level evaluation will 

continue to be improved upon each year. 

One challenge of this form of program level evaluation is for low volume roads. On these types of roads, 10 

years of data is needed to determine a crash trend and ultimately a project being constructed. In addition, 

MDT's evaluation is based on 5 years "before" and "after" data which may not correspond with the original 

trend identification due to the regression to the mean. Consequently, the naïve before/after study may not 

produce results that are consistent with the anticipated CMF that was used. 

What other indicators of success does the State use to demonstrate effectiveness and 

success of the Highway Safety Improvement Program? 

• HSIP Obligations 

• Increased awareness of safety and data-driven process 

• Increased focus on local road safety 
2020 Montana Highway Safety Improvement Program

Page 52 of 60

Another method MDT uses to indicate the HSIP Program's Success is the ability to identify and obligate HSIP 

Funds to address safety needs throughout the state on all public roads. MDT's HSIP Funding has grown over 

the last several years which has allowed MDT to identify and fund more significant size safety projects. This 

has included large infrastructure type projects, including several roundabouts on non-MDT routes (local road 

safety) and shoulder widening/slope flattening on secondary roadways which have limited funding sources.

The HSIP Program's success has also increased the awareness of safety within the agency as a whole. This 

has translated into more collaboration between bureaus as other projects are designed and implemented 

benefiting both the safety program and ultimately the traveling public.

MDT has a process to evaluate safety projects. At this time, the 2020 evaluation has not been completed and therefore it not referenced or included in this report. MDT's 2019 evaluation results are included. These are for a simple before 

/ after study using 5 years of before/after data. In addition, small projects with similar scope have been grouped together for analysis.

The challenge of completing a simple before/after study is that the 5-year before period may not be representative of the crashes that initiated the safety improvements or the data may be skewed due to the randomness of crashes on low 

volume roads. In addition, although the guardrail installations resulted in a significant reduction in crash severity and number of crashes, one severe crash resulted in an overall negative b/c. The simple before/after study method is heavily 

influenced by severe crashes.
