Executive Summary

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

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

local roadways. This includes large systemic applications (curve signing, sinusodial centerline rumble strips, 

median cable barrier) as well as for spot locations. The spot safety improvements have ranged from 

delineation, striping 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. MDT is 

currently in the process of upgrading their SIMS software to improve identification of potential sites and 

tracking of projects. 

Montana did see an increase in severe injury crashes in 2020. The COVID pandemic changed the way drivers 

utilized Montana's highways resulting in more fatal and serious injury crashes. This included higher speeds 

and riskier driving behaviors. This corresponds with results being seen in other western states for 2020.

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 Montana's HSIP 

available funding, are nominated as HSIP Funded Safety Projects.

Where is HSIP staff located within the State DOT? 

 Engineering

The HSIP Program and associated Staff are located in the Traffic & Safety Bureau within MDT's Engineering 

Division.

How are HSIP funds allocated in a State? 

• Central Office via Statewide Competitive Application Process

The Safety Engineering Section administers MDT's HSIP Program. MDT's program is a centrally administered 

program within MDT's Headquarters Office.

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 

Improvement Program. A nomination/application for HSIP projects is included on the MDT internet page at: 
2021 Montana Highway Safety Improvement Program

Page 6 of 48

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 local and Tribal roads. These tools are 

anticipated to be usable in late 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 was updated in 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.
2021 Montana Highway Safety Improvement Program

Page 7 of 48

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 a few local agencies. This web based system allows local enforcement agencies to input crash 

information via the internet, if they choose to participate. Law enforcement agencies are now working with 

other vendors to collect their local crash data. MDT and MHP are working with these agencies to develop ways 

for this crash data to be imported into MHP's crash database and become usable by MDT for it's HSIP 

Program. Approximately eight departments report about 80% of all local crashes.

In 2014, MDT implemented an upgrade to the safety database and analysis tools. This current system, referred 

to as the Safety Information Management System (SIMS) 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 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 current system also 

allows MDT to utilize MHP citation data. MDT is currently in the process of updating this system and is under 

contract with AASHTOware. This new crash database and analysis tool is anticipated to be in full production by 

late 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.

 HSIP funds are used to address which of the following systemic 

improvements? 

• Cable Median Barriers

• Horizontal curve signs

• Install/Improve Signing

• Rumble Strips

• Wrong way driving treatments

In State Fiscal Year (SFY) 2021, MDT obligated two (2) large centerline rumble strip projects in the Missoula 

District. These rumble strip projects accounted for over 35% of HSIP funds expended for SFY 21.

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

MDT uses available engineering resources to determine the most appropriate safety countermeasure for a 

given location. Any new FHWA guidance or academic research is utilized to help in this process.

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. MDT recently updated its Roadway 

Departure Montana Specific SPF's utilizing the same methodology.

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

elaborate.

Criteria for the HSIP Program's annual list is primarily focused on 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 identify potential countermeasures. Conceptual designs are 

developed with cost estimates.
2021 Montana Highway Safety Improvement Program

Page 12 of 48

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

upgrades, centerline rumble strips and interstate median barriers. These projects are being installed on a large 

district-wide scale. MDT will also be initiating additional large scale systemic projects including developing local 

road safety plans.

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

Safety (LOSS), and diagnostic norms. MDT is using the updated tools for continued evaluation of the HSIP as 

well as analysis for other agency projects.

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. The National 

Highway Traffic Safety Administration (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 (impairment, cellphone 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 2022 Targets *

Number of Fatalities:199.2

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

The 2020 CHSP update established the target setting methodology for the five federal performance measures 

for the five-year life of the plan. The methodology is based on historical trend data and considers potential 

impacts of COVID-19. Trend analysis identified ambitious yet achievable targets for each of the performance 

areas.

Based on this approach and with input from the safety stakeholders, the methodology that will be used to 

calculate and set annual targets for each performance measure were established. Performance measures are 

a five-year roiling average expressed as an annual number. 

This supports the state's SHSP (known as Montana's Comprehensive Highway Safety Plan (CHSP)) by 

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

from 952 in 2018 to 476 in 2030.

Performance Measures for fatalities is moderate. The target is for an annual reduction of 3 fatalities,

Performance Measures for non-motorized fatalities & serious injuries is low moderate. The target is for an 

annual reduction of 1 fatality or serious injury.

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 virtually in the spring of 2021 to establish the 

2022 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 2020 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 182.2 191.0

Number of Serious Injuries 860.4 755.0

MDT has made significant progress on 3 of the 5 safety targets for 2020. 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 2020 Montana saw a substantial increase from 184 to 213 annual fatalities. This is the 2nd year in a row for 

seeing fatalities increase. Nationwide, the year 2020 saw a significant increase in severe crashes after the 

COVID pandemic began. In Montana, behavioral choices were a major contributing factor to the increase. 

Overall, one of the major challenges for fatal and serious injury crashes is mitigating 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 fairly new to MDT. 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.

There are 2 challenges with this type of evaluation:

1. This form of program level evaluation is difficult 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.

2. Due to the severity of one fatal crash, the overall countermeasure results of a naïve before/after study can 

show a negative benefit cost ratio. The benefit cost ratio heavily weighs the fatal crash in the calculation and 

negates any other crash reduction being attained. Thus, the negative benefit cost ratio does not always 

accurately represent a safety improvement as a overall positive benefit.

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

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 sized 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.

Project Effectiveness

Provide the following information for previously implemented projects that the State evaluated this reporting period. 

Describe any other aspects of HSIP effectiveness on which the State would like to elaborate.

MDT has an annual process in place to evaluate safety projects. This evaluation process includes a simple before/after 5-year study. In addition, small projects with similar scope are grouped together for analysis.

MDT is looking to improve upon the evaluation process in the next few years. The current process does not provide for regression to the mean for low volume roads.
