Executive Summary

WYDOT has an established an 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 systematic and 

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? 

 Operations

How are HSIP funds allocated in a State? 

• Formula via Districts/Regions 

• SHSP Emphasis Area Data 

• Other-Safety Management System 

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 Management Committee that 
2022 Wyoming Highway Safety Improvement Program

Page 6 of 41

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. 

• Design 

• Districts/Regions 

• Governors Highway Safety Office 

• Local Aid Programs Office/Division 

• Operations 

• Planning 

• Traffic Engineering/Safety 

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 disseminated 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. 

Identify which external partners are involved with HSIP planning. 

• FHWA 

• Governors Highway Safety Office 

• Law Enforcement Agency 

• Local Government Agency 

• Local Technical Assistance Program 

• Regional Planning Organizations (e.g. MPOs, RPOs, COGs) 

• Tribal Agency 

Describe coordination with external partners. 

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. 

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

elaborate. 

The Highway Safety Office has developed 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 driving the HSIP project selection 

process for WYDOT.
