Executive Summary

The Montana Department of Transportation (MDT) continues to successfully implement the Highway Safety 

Improvement Program (HSIP) Funds throughout the State. The program continues to identify safety 

improvements on all public roads including state, county, city, tribal, BIA and local roads. This past year two 

large scale systemic projects were implemented across multiple Districts. This included centerline rumble strips 

on primarily two-lane routes and high tension median cable barrier on the interstate system. Spot safety 

improvements have ranged from roundabouts, curve reconstructions, shoulder widening to intersection signing 

upgrades and roadway lighting projects. 

MDT recently updated its Safety Management System to an AASHTOWare product called Numetrics.. Using 

this new system and Montana Specific Safety Performance Functions, the HSIP program is able to provide 

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

Montana did see severe injuries increase for another year in 2021. The COVID pandemic affected driver 

behavior on Montana's roadways resulting in more fatal and serious injury crashes. This included higher 

speeds and riskier driving behaviors. This increase was also the case in neighboring states.

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

How are HSIP funds allocated in a State? 

• Central Office via Statewide Competitive Application Process 

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. These governments may also work through MDT's District Offices to request a location 

be reviewed by MDT's Safety Program. 

A nomination/application for HSIP projects is included on the MDT internet page at 

https://mt.accessgov.com/mdt/Forms/Page/mdt-tp/a0f2b61b-96af-4527-9f99-0092c3c434dc/28f1e5ac-bbc9-

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 explored to assist with identifying potential projects on low volume local and Tribal roads

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 the 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: 

https://www.mdt.mt.gov/visionzero/plans/chsp.aspx

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 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.

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 was 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 late 2021 MDT was under contract with AASHTOWare to upgrade its safety database and analysis tools. 

This new system, AASHTOWare Numetrics will allow MDT to access the MMUCC compliant crash data being 

collected by the Montana Highway Patrol. The system also will have access to many roadway data elements 

including the Fundamental Data Elements identified by FHWA. Additionally, MDT will retain access to the MHP 

crash investigator’s reports, if additional detail on the particular crash is required. Lastly, the upgraded system 

will continue to allow access to MHP citation data for traffic and safety engineering purposes. 

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.

2022 Montana Highway Safety Improvement Program

Page 11 of 60

MDT identifies and funds systemic projects each year. The percentage of systemic projects varies by year. In 

State Fiscal Year (SFY) 2022, MDT obligated two (2) large median cable barrier projects along the interstate 

system. These two projects accounted for 26% of HSIP funds expended for SFY 22.

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(s) 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 

related 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.

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, centerline rumble strips and 

interstate median barriers. These projects are being installed on a large district-wide scale.

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.

Retaining/recruiting experienced design staff and acquiring right of way are two significant challenges for 

constructing HSIP safety improvements. Both of these impede obligating HSIP funds.

For retaining and recruiting experienced design staff, the agency has pursued multiple avenues to improve this 

situation. This has included identifying alternative design and delivery methods. However, this results in higher 

project costs and fewer HSIP projects being delivered.

On larger roadway departure and intersection safety improvements, the right of way acquisition has added 

significant delivery time and overall project cost. This has particularly been challenging with intersection 

projects in urban and urban-fringe areas. MDT is pursuing innovative intersection treatments to minimize 

impacts as well as alternative delivery methods.

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 2023 Targets *

Number of Fatalities:223.2

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 in the spring of 2022 to establish the 2023 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 2022 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.

Montana followed the national trend in 2021 with increased fatal and serious injury crashes. This trend began 

in 2020 with the onset of the COVID pandemic and continued throughout 2021. Behavioral choices played a 

significant role in this high severity crash increase. The major contributing factors included increased highway 

speeds and high risk behavior.

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: 

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

Slope flattening or elimination of roadside hazards; 

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

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 
2022 Montana Highway Safety Improvement Program

Page 52 of 60

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.

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 2-4 years. The current process does not provide for regression to the mean for low volume roads.
