Executive Summary

In the reporting period, the Montana Department of Transportation (MDT) successfully utilized our

allotted Highway Safety Improvement Program (HSIP) funds on Montana's roadways. MDT also

completed or has initiated Corridor Safety Audits (CSA) on two locations in the state. Recommendations

from these CSA's are being utilized to supplement our historical site specific identification of safety

improvements. MDT also completed an upgrade of our safety analysis software as well as a Roadway

Departure Study (RDS). The RDS included the development of Safety Performance Functions (SPFs) and

diagnostic norms for all rural, on‐system roads for both total crashes as well as road departure crashes.

This report and the associated tools are being used for identification of projects for the 2015 Highway

Safety Improvement Program (HSIP).  

MDT continues to evaluate our historical processes for identifying locations for safety improvements

and is discussing how to balance our site specific program with systemic improvements as well as

potentially completing behavioral projects using HSIP funds. Overall totals for fatalities and severe

injuries in the state were down nearly 13% in 2014 as compared to 2013.  Additionally, overall fatalities

and serious injuries are down over 32% since the establishment of the goal in 2007. MDT continues

efforts to conduct outreach to local government agencies on the availability of HSIP for completion of

safety improvements on local roads.

Introduction

The Highway Safety Improvement Program (HSIP) is a core Federal‐aid program

with the purpose of achieving a significant reduction in fatalities and serious

injuries on all public roads. As per 23 U.S.C. 148(h) and 23 CFR 924.15, States are

required to report annually on the progress being made to advance HSIP

implementation and evaluation efforts.    The format of this report is consistent

with the HSIP MAP‐21 Reporting Guidance dated February 13, 2013 and consists

of four sections: program structure, progress in implementing HSIP projects,

progress in achieving safety performance targets, and assessment of the

effectiveness of the improvements.

Describe how local roads are addressed as part of Highway Safety Improvement Program.

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

enforcement agency, are available to MDT.  In the past year, MDT has 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 attached to this report (HSIPAPPLICATION

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.

Briefly describe coordination with internal partners.  

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

Highway Safety Plan (CHSP).   The CHSP has recently undergone an update.  The CHSP update was

completed in May 2015.  The updated CHSP is available at:  

http://www.mdt.mt.gov/publications/docs/plans/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. Enforcement agencies

identify locations and request site reviews. Local and Tribal agencies can forward safety projects or

request MDT evaluate areas of interest. MDT District Offices also submit sites for investigation and

participate in the engineering study to determine crash trends and countermeasure selection. Project

selection is currently based on the benefit/cost ratio method. MDT has advanced some systemic

improvements (curve signing as an example) based on the strategies outlined in the CHSP.  

Appropriate entities within MDT are invited to participate in Corridor Safety Audits (CSA's). These

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.

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

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

deployed 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 Office of Court Administration (OCA) maintains a central court repository (CCR), which contains

electronic case records from all Courts of Limited Jurisdiction and District Courts. The CCR includes

records on all citations, as well as corresponding disposition information. The Department of Justice

(DOJ) receives any CCR information that must be applied to a driver’s record. Working with the OCA and

the DOJ, MDT receives the same driver information for use in traffic safety analysis. While the data is not

yet available for traffic safety users, a project to increase the scope of the data received and to develop

the reports and analysis needed is listed as a medium priority in the Montana Traffic Records Strategic

Plan Annual Element.  Additionally, in the past year MDT has worked with MHP to gain access to the

MHP citation data.  

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

and Safety is taking the lead in the areas of road departure crashes and intersection crashes. MDT is

conducting a minimum of two CSA's per year.

Other: Other‐During the reporting period, MDT implemented a new crash database that allows

completion of network screening for on‐system rural segments using Montana specific safety

performance functions.

Describe any other aspects of the Highway Safety Improvement Program methodology on which you

would like to elaborate.  

To identify potential location for development of the 2015 HSIP, MDT has elected to screen the

network using the following criteria:

1) Safety performance function developed for road departure crashes resulting in a fatality or

injury.

2) Sliding window using a 1 mile window length and a 0.1 mile step.

3) Crash data period is 2004‐2013 for initial screening.

4) Sites with a Level of Service of Safety IV and a minimum number of crashes.  The minimum

number of crashes varies by system.  For minor arterials and major collectors the number of

crashes was greater than or equal to 4.  For all other routes the minimum number of crashes was

5.   

5) Sites requested for review by another agency, MDT District personnel, citizens, as well as

other MDT staff, were also included in the initial list of locations.   

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
2015 Montana     Highway Safety Improvement Program

11

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 district wide horizontal curve signing upgrade projects. The intent of these

projects is to complete a proactive improvement to upgrade all the curve warning signs to a consistent

standard. MDT also completed a systemic wrong way signing upgrade to all interstate ramps.  The intent

of this project was to bring the signing for all off‐ramps to a consistent standard.     

MDT has also completed development of a Roadway Departure Study. This study included development

of Safety Performance Functions (SPFs), Level of Service of Safety (LOSS), and diagnostic norms for rural

on‐system routes. MDT is using these tools and methodologies for development of the HSIP as well as

analysis of other agency projects. As part of the Study, MDT has begun nominating centerline rumble

strip projects as a proactive effort to address head‐on, sideswipe opposite direction, and run off the

road left crashes. MDT is also developing SPF's and diagnostic norms for intersections. Completion of

this project is anticipated in 2015/2016.

Describe any other aspects of the general Highway Safety Improvement Program implementation

progress on which you would like to elaborate.

Historically, MDT has been very successful in utilizing HSIP funds. We are evaluating our current project

nomination guidelines in an effort to blend the historical focus on site specific projects with

proactive/systemic/systematic projects as well as improvements recommended in CSA's. Completion of

an updated MDT HSIP Manual is planned in the near future.  

MDT has a process to perform CSA's on selected corridors. The intent is to develop safety

recommendations as the engineering component of this process and pursue strategies such as

enforcement activities and public education, involving the disciplines of the participants in the

development of the strategic highway safety plan. The CSA's recommend short, medium and long term

improvements from a behavioral and engineering perspective.  

MDT has also completed development of a Roadway Departure Study. This study included development

of Safety Performance Functions (SPFs), Level of Service of Safety (LOSS), and diagnostic norms for rural

on‐system routes. MDT is using these tools and methodologies for development of the HSIP as well as

analysis of other agency projects. As part of the Study, MDT has begun nominating centerline rumble

strip projects as a proactive effort to address head‐on, sideswipe opposite direction, and run off the

road left crashes. MDT is also developing SPF's and diagnostic norms for intersections. Completion of

this project is anticipated in 2015/2016.  

MDT is also developing a non‐infrastructure HSIP project.  The goal of the project is the development of

a media campaign to educate drivers on road departure crashes.  The project was started in the spring

of 2015 with final completion anticipated for the summer/fall of 2016.

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

In the spring of 2014, Montana Department of Transportation Director Mike Tooley announced “Vision

Zero,” a multi‐pronged initiative with the ultimate goal of eliminating deaths and injuries on Montana

highways.  Montana Highway Safety Stakeholders completed an update of the Montana CHSP in the

spring of 2015.  The updated CHSP formalizes Montana's vision of zero deaths and injuries on Montana's

roads.    

While the overall goal of the CHSP is zero fatalities and injuries, the CHSP update maintains an interim

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

summary of the number of fatalities and serious injuries from 2006‐2014:  

Year ‐‐ Fatalities and Serious Injuries

In order to determine the per capita fatality and serious injury rates the Montana Department of

Transportation (MDT) queried the MDT crash database for crashes in which the driver or pedestrian

involved is 65 years of age and older for 2005‐2013 time frame.  

A summary of the number of drivers or pedestrians 65 years of age or older who were injured (based on

severity) in the crash were tabulated. For reporting purposes, the State of Montana only evaluated

crashes that resulted in a fatal injury or serious (incapacitating) injury to the older driver or pedestrian.  

Other occupants in the crash are not included in the calculation.

The fatal injury crash data was obtained by querying the Fatality Analysis Reporting System (FARS)

database.  

The criteria used for querying the FARS database was as follows:  

1) Select State: Montana  

2) Injury Severity: Fatal Injury  

3) Age: 65 years or older  

4) Person Type: Driver of a Motor Vehicle In‐Transport and/or Pedestrian  

The population data was obtained from Attachment 2 of the Older Driver and Pedestrian Special Rule

Interim Guidance (February 13, 2013) provided by the FHWA.  

MDT then used a 5‐year rolling average for each year of reporting. A similar query was run for crashes

involving a pedestrian(s) that were 65 years of age and older for the same time period and 5‐year rolling

average was calculated.  

To derive the fatality rate and serious injury rate for persons 65 years of age or older per 1,000 total

population that are age 65 or greater, the number of fatalities and serious injuries were added together

for each year of study and divided by the proportion of Montana’s population that is 65 years of age and

older for the corresponding year obtained from Attachment 2. As mentioned above, once the yearly

fatality rates and serious injury rates were calculated a 5‐year rolling average was used for the various

reporting years.  

An example calculation for the combined Fatal and Serious Injury Rate per capita for Drivers and

Pedestrians 65 years of age and older for 2011 (2011, 2010, 2009, 2008, and 2007) is illustrated below:  

(Fatal + Serious Injury 2011 Drivers and Pedestrians 65 years of age and older/2011 Population Figure)+

(Fatal + Serious Injury 2010 Drivers and Pedestrians 65 years of age and older/2010 Population Figure)+

(Fatal + Serious Injury 2009 Drivers and Pedestrians 65 years of age and older/2009 Population Figure)+

(Fatal + Serious Injury 2008 Drivers and Pedestrians 65 years of age and older/2008 Population Figure)+

(Fatal + Serious Injury 2007 Drivers and Pedestrians 65 years of age and older/2007 Population Figure)/5  

All rates were rounded to the nearest tenth as described in the Section 148‐Older Drivers and

Pedestrians Special Rule Interim Guidance Report dated February 13, 2013. The same methodology was

consistent with a State strategic highway safety plan and corrects or improves a hazardous road location

or feature or addresses a highway safety problem.  

HMVMT means hundred million vehicle miles traveled.

Non‐infrastructure projects are projects that do not result in construction. Examples of non‐

infrastructure projects include road safety audits, transportation safety planning activities,

improvements in the collection and analysis of data, education and outreach, and enforcement

activities.

Older driver special rule applies if traffic fatalities and serious injuries per capita for drivers and

pedestrians over the age of 65 in a State increases during the most recent 2‐year period for which data

are available, as defined in the Older Driver and Pedestrian Special Rule Interim Guidance dated

February 13, 2013.  

Performance measure means indicators that enable decision‐makers and other stakeholders to monitor

changes in system condition and performance against established visions, goals, and objectives.

Programmed funds mean those funds that have been programmed in the Statewide Transportation

Improvement Program (STIP) to be expended on highway safety improvement projects.

Roadway Functional Classification means the process by which streets and highways are grouped into

classes, or systems, according to the character of service they are intended to provide.

Strategic Highway Safety Plan (SHSP) means a comprehensive, multi‐disciplinary plan, based on safety

data developed by a State Department of Transportation in accordance with 23 U.S.C. 148.  

Systemic safety improvement means an improvement that is widely implemented based on high risk

roadway features that are correlated with specific severe crash types.  

Transfer means, in accordance with provisions of 23 U.S.C. 126, a State may transfer from an

apportionment under section 104(b) not to exceed 50 percent of the amount apportioned for the fiscal

year to any other apportionment of the State under that section.
