Executive Summary

WYDOT has an established HSIP program with processes in place for the collection of data, implementation of 

projects, and annual reporting. Each fiscal year, historically, Wyoming obligates a majority of their HSIP 

apportionments, these funds are obligated on projects, which are eligible under the requirements of the 

program. WYDOT effectively manages the HSIP and their Highway Safety Program manager is responsible for 

both the behavioral and engineering aspects of the program, reporting to both NHTSA and FHWA. This 

overarching management of the program provides for a consistent approach to addressing highway safety 

needs throughout the State.

The Highway Safety Program continues to be process driven and consistent when approaching HSIP projects 

and reporting requirements. WYDOT is currently inconsistent between the Highway Safety Program and other 

programs within the DOT. Safety elements are often included on projects that are funded through sources 

other than HSIP. WYDOT is working towards a standard process of coordination between programs to ensure 

that safety projects and safety project elements are being identified and prioritized before the funding is 

utilized. This ensures WYDOT efficiently and effectively utilizes the available funding on high value projects 

and project elements.

Progress is being made through the Safety Innovation Team that consists of the Highway Safety Program, 

Traffic Program, Planning Program and Highway Development Program. The Highway Safety Program has 

established a new position to oversee Safety Management.

WYDOT is also improving their process for the evaluation of safety benefits from projects and project elements 

that are implemented using HSIP funding. The Safety Management System provides a mechanism for 

quantifying the benefits of safety treatments which in turn allows for more effective utilization of HSIP funds on 

future HSIP projects and project elements.

WYDOT Highway Safety continues to implement the HSIP through strategies, activities, and/or projects on 

public roads that are consistent with their data driven Strategic Highway Safety Plan (SHSP) with the goal of 

reducing fatal and serious injury crashes.

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 is based upon the goals and areas identified in the SHSP. HSIP eligibility policies focus on 

addressing the greatest safety needs within the State. Rural road safety needs are addressed through the 

HRRR program (which is a subset of the HSIP) managed through an agreement with the UW LTAP Center. 

The greatest safety needs are identified through the Safety Management System (SMS) which establishes a 

mechanism for the prioritization of HSIP funding.

WYDOT considers crash, roadway and traffic data when identifying potential HSIP projects. The SMS allows 

for various programs and Districts to optimize the use of safety funds on the State's roadways. The SMS 

allows WYDOT decision makers to identify the locations that warrant attention and then select the most cost 

effective safety treatments to propose at each potential project location.

WYDOT implements both spot location treatments for high-crash/high-risk locations as well as systemic safety 

improvement projects. Due to the rural nature of Wyoming the majority of HSIP projects address rural road 

safety needs. Safety strategies proven to be effective on rural roads are applied using HSIP funds.

Where is HSIP staff located within the State DOT?

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

The local county roads and tribal roads are included in the HSIP by the Wyoming rural road safety program 

(WRRSP) administered by the UW LTAP center. The program reviews crash and roadway feature data to 

develop high risk road locations. The work done by the LTAP then includes assistance in putting projects 

together with the local jurisdictions to address the identified roadway safety needs.

There are two MPO's in Wyoming and they are represented on the Safety Mangagement Committee that 

identifies emphasis areas for the SHSP. Projects are proposed and developed by the MPO's with regard to 

their own identified needs and assistance is provided in data and information.

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

are involved with HSIP planning.

Describe coordination with internal partners.

Internal partners are asked to provide their expertise in the various areas that they represent. The coordination 

is required at many levels based upon the policies of WYDOT. Information is developed and disemminated by 

the Highway Safety Office. The information is used to make decisions regarding project programming and 

design by the other WYDOT programs responsible for that part of the project development and 

implementation.

WYDOT is structured with the WHP and Governors Rep for Highway Safety (NHTSA) within its organization. 

The Highway Safety Office chairs a Safety Management Committee that meets 3-4 times per year to discuss, 

investigate, plan and direct the numerous safety partners throughout the state on the SHSP and other higher 

level issues regarding Highway Safety.

Program areas and strategies are discussed to assist other safety partners in their efforts to reduce fatal and 

serious injury crashes in the State.

Have any program administration practices used to implement the HSIP changed since the last reporting 

period?

No

Are there any other aspects of HSIP Administration on which the State would like to elaborate?

Yes

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

The Highway Safety Office has been the lead in developing a Safety Management System (SMS) for WYDOT. 

The SMS is maturing rapidly and becoming the go to place for counter measures and projects that have higher

benefit/cost ratios. The SMS is based upon the principles contained in the Highway Safety Manual and is very 

dependent upon data. The SMS development has been a long process but it is now on the verge of driving the 

HSIP project selection process for WYDOT.

Program Methodology

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

and evaluation processes?

No

WYDOT has an operating policy regarding Highway Safety that needs updating as the Safety Management 

System becomes more widely used for Planning, Implementation and Evaluation of the HSIP. The operating 

policy is under review by WYDOT leadership.

With the large amount of federal lands in Wyoming with many paved and un-paved roadways it would be helpful in the Federal Government agencies would provide their roadway information to WYDOT so that it can be included.

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.

The State of Wyoming through the Department of Transportation Planning program will continue to pursue the necessary data collection to complete the MIRE fundamental data elements on all public roads. One glaring problem is the 

Federal Land agencies NOT providing this data to WYDOT.

Provide the suspected serious injury identifier, definition and attributes used by the State for both the crash report form and the crash database using the table below. Please also indicate whether or not these elements are 

compliant with the MMUCC 4th edition criteria for data element P5. Injury Status, suspected serious injury.

5 year rolling 

average 

means the average of five individuals, consecutive annual points of data (e.g. annual
