Executive Summary

Over the past five (5) years, MDT's Safety Program has made significant strides towards improving safety on 

Montana's Transportation Network. This has been a result of several factors:

• Increased HSIP Funding; 

• MDT’s Safety Information Management System (SIMS) to identify, analyze and track HSIP projects; 

• MDT’s Roadway Departure and Intersection Plans to identify locations for further analysis and potential 

safety improvements; 

• MDT’s systemic application of multiple safety countermeasures (centerline rumble strips, wrong-way 

interstate signing, horizontal curve signing, median cable barrier, reflective backplates, etc); 

• Identifying more substantial projects on non state-owned roadways; 

• Researching methodologies to determining how to apply HSIP Funding to low volume roads with 

minimal crash data availability, 

• Developing Median Cable Barrier Warrants 

• Educating the public on benefits of controversial/contentious safety improvements. This is done through 

MDT’s new Public Information Process on many projects, including HSIP projects; 

Over these past five years, Montana has seen a decrease in traffic fatalities. MDT will continue its efforts to cut 

fatal and serious injury crashes in half by 2030 by addressing crash clusters on all public roads.

One of MDT’s challenges is the inability to use HSIP Funding towards behavioral type campaigns. Behavior 

plays a recurring role in fatal/serious injury crashes and MDT is hampered by the inability to address this need.

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 HSIP Program is a centrally administered program through the Safety Engineering Section which is within 

MDT's Traffic and Safety Bureau. 

Each year, the Safety Engineering Section develops criteria to identify potential hot-spot crash locations for 

review. The Section also identifies potential systemic improvements for longer roadway segments and/or 

corridors. 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

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

within the Engineering Division.

How are HSIP funds allocated in a State? 

• Central Office via Statewide Competitive Application Process 

All crashes investigated by the Montana Highway Patrol (MHP), 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 .
2019 Montana Highway Safety Improvement Program

Page 6 of 46

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. Those tools are 

anticipated to be usable in late 2020. 

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

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. 

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-District Personnel

• 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 will be completed 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 
2019 Montana Highway Safety Improvement Program

Page 7 of 46

• 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.

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. 

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

taking the lead in the areas of roadway departure crashes and intersection crashes.

Program Methodology

Does the State have an HSIP manual or similar that clearly describes HSIP planning, 

implementation and evaluation processes?

No

Although MDT has an outdated Safety Manual, MDT has a clearly defined and documented HSIP process in 

place. The existing MDT Safety Manual is currently being re-written for use by the Traffic and Safety Bureau 

and is anticipated to be complete by early 2020. This Safety Manual will include formal documentation of the 

HSIP Process from project selection through implementation and project evaluation.

 HSIP funds are used to address which of the following systemic improvements? 

• Cable Median Barriers

• Horizontal curve signs

• Install/Improve Pavement Marking and/or Delineation

• Install/Improve Signing

• Other-Flashing Yellow Arrows

• Rumble Strips

Systemic projects may be stand-alone projects across a District (District curve signing or centerline rumble 

strips) or along a corridor (signing, striping, delineation, rumble strips, etc). The past several years MDT has 

been implementing these type of projects on an annual basis. These applications provide a pro-active 

approach to safety.

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 is currently completing a research project to determine an appropriate methodology for identifying and 

implementing Low Cost Safety Improvements on Low Volume Roads. During this process, MDT is coordinating 

with Montana's LTAP Office and other Stakeholders.

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 its Roadway Departure 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. The Intersection Safety Study was also developed based on similar methodology.

MDT's Road Design is also beginning to integrate the HSM methodologies into their design process. To assist 

in this endeavor, FHWA recently provided training to MDT Staff and Consultants through their Resource 

Center.
2019 Montana Highway Safety Improvement Program

Page 14 of 46

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

elaborate. 

To identify potential locations for the 2019 HSIP, criteria being used to screen the network are as follows: 1) 

Fatal and Serious Injury Roadway departure crashes; 2) Intersections identified by Bureau and/or District 

and/or Intersection Safety Plan; 3) Crashes involving non-motorized vulnerable users including bicyclists 

and/or pedestrians. 4) 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 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 in various levels of design and/or construction. MDT is also looking at other large scale systemic 

projects including interstate median barrier and developing local road safety plans.

MDT is currently updating its Roadway Departure Safety Performance Functions (SPFs), Levels of Service of

Safety (LOSS), and diagnostic norms. Once updated in 2020, MDT will replace the current tools for continued 

evaluation of the HSIP as well as analysis of other agency projects.

MDT has recently developed SPF's and diagnostic norms for intersections. These intersection tools are being 

used in the development of the 2019 HSIP List. They will also be utilized in analysis for other agency projects 

and future HSIP Lists.

In addition, MDT is working towards identifying more safety improvements on local and tribal roads, in 

particular low volume roads and high severity crash types. Due to minimal crash data available on low volume 

roads, MDT has started a 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" is in 

the early phases and completion is anticipated in late 2020.

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 recently completed its Median Cable Barrier Study. This study included developing MDT-specific median 

cable rail guidelines and warrants for installation. This study has been utilized in developing HSIP projects in 

the 2018 HSIP List and will continue to be used in future lists.

MDT recently completed its Intersection Safety Study. Phase I of this study included development of Safety 

Performance Functions (SPF’s), Level of Service of Safety (LOSS), and diagnostic norms for urban/rural - 3 or 

4 legged intersections. Phase II included network screening of Montana's intersections for potential for crash 

reduction. MDT is now utilizing the SPF's and results of Phase II to identify locations for further analysis in the 

HSIP Program.

MDT is currently finalizing a manual to (1) evaluate and document MDT’s current process for development of 

HSIP projects; (2) evaluate and document the current Fundamental Data Elements (FDE) contained in MDT’s 

Safety Information Management System (SIMS); (3) review and update, if necessary, MDT’s current process 

guidelines for completion of Road (Corridor) Safety Audits; (4) review, enhance, and consolidate current 

analytical processes, practices, and procedures for incorporation of safety enhancements into non-HSIP 

projects; (5) develop documentation and processes which combines documentation from the recently 

completed SIMS project, with the analytical tools developed as part of the Road Departure Study and the 

Intersection Study; and (6) prepare one chapter containing guidelines for inclusion of pedestrian safety 

countermeasures. The anticipated completion date for this manual is January 2020.

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 between MDT Engineering, the 3 MPO's 

and the State Highway Traffic Office. Representatives from each group met in the spring of 2019 to establish 

the 2020 Safety Performance Targets. For the final step, 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 2018 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. 

MDT has met or made significant progress for our safety targets in 2018. MDT was successful in meeting 3 of 

the 5 Montana 2018 Safety Performance Targets and were better than the baseline for all 5 target areas.

Although the fatalities and fatality rate were not met, fatal crash numbers in 2018 have continued on a 

downward trend.

Applicability of Special Rules

Does the HRRR special rule apply to the State for this reporting period? 

Yes

For the 2018 HSIP List, the Montana definition of High-Risk Rural Roads is: any roadway functionally classified 

as a rural major or minor collector or a local road with significant safety risks. Per §23 USC 148(d)(2), MDT’s 

definition of significant safety risk is “information gathered through means such as field reviews, safety 

assessments, road safety audits, and local knowledge and experience.” Using information from observations in 

the field can identify high-risk locations that may not be identified through data analysis or by identifying 

roadway characteristics.

Provide the number of older driver and pedestrian fatalities and serious injuries 65 

years of age and older for the past seven years.

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
2019 Montana Highway Safety Improvement Program

Page 38 of 46

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 2019 evaluation has not been completed and therefore it not referenced or included in this report. MDT's 2018 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.

Describe actions the State will take moving forward to meet the requirement to have complete access to the MIRE fundamental data elements on all public roads by September 30, 2026. 

MDT has collected the final data element using in-house roadway images, Google Street View and field observation efforts.

MDT will now QA/QC the collected data, format and load into our MIRE database by 12/31/2020.

Did the State conduct an HSIP program assessment during the reporting period? 

MDT's HSIP program assessment is currently underway. This assessment will result in the completion of a safety manual in early 2020.
