Executive Summary

Wyoming adopted a revised Strategic Highway Safety Plan (SHSP) in June of 2012 through its Safety

Management System committee (SMS).  The SMS committee adopted two additional Emphasis Areas

and reorganized the sections within the document.  The SHSP attempts to bring together the driver

behavior and engineering factors to provide a safer transportation system as a whole.   

The methodology for prioritizing projects is a combination of engineering judgment, the geometric

conditions and crash information for identified hazardous crash types and locations. The roadway safety

projects were selected and prioritized in the State Transportation Improvement Program with input

from the Highway Safety Office, Traffic Program and the five District Engineering Programs.  Crash

locations are typically not consistent year to year.  Wyoming uses systematic treatments to improve

safety on roadway segments and other locations that have similar characteristics that are a safety

concern.  Wyoming also uses stand‐alone safety projects to address safety issues at a specific spot, for

example at an intersection or along a roadway segment.  A third general project type that Wyoming

utilizes to improve the system is combined projects with other work such as pavement projects or

bridge projects.

The overall safety goal of WYDOT with respect to safety is to “Reduce the frequency and severity of

crashes on the state’s roadways with the resources available.”

That essentially translates to getting the most reduction in crashes possible from the dollars spent in the

name of safety.

The WYDOT Safety Management System is a collection of tools, business processes, cross‐program work

flows, and the policy on Highway Safety designed to facilitate the identification and correction of safety

concerns on the roadway network in Wyoming, and to achieve the overall safety goal.

The Safety Management System supports WYDOT business objectives by helping to accomplish the

following:  

 Optimize safety spending

o WYDOT will achieve a higher level of safety improvement (reduction in frequency

and/or severity of crashes) through the project work funded in the name of safety.

o WYDOT will be able to get the highest level of benefit of safety spending by being able

to identify and focus on the projects that will provide the greatest reduction for the

lowest cost.  

 Transparency  
2015 Wyoming     Highway Safety Improvement Program

2

o WYDOT will be able to provide solid, defensible rationale for decisions regarding safety

investments, and be able to communicate clearly to the public, the federal partners, and

state legislature with regards to safety efforts

o The prioritization of safety investments is in line with the WYDOT Balanced Score Card

measures for safety, as well as with other associated plans (WYDOT Strategic Plan, the

Strategic Highway Safety Plan, the Traffic Records Strategic Plan, etc...)  

o Focusing on fatal and incapacitating injury crashes (referred together as “critical

crashes”), while also considering counts of all crashes

 Facilitate Cross‐Program efforts

o Interactions between various parties will be streamlined with smoother flow of

information and actions between District management, Traffic Operations, Project

Development, Planning, and Highway Patrol in addition to Highway Safety with regards

to the development and deployment of safety remedies.

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.

The local county 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.

Briefly 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.

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

Fatal and Serious Injury crashes in Wyoming have increased over the last year, but the trend is

downward when looking at a five year period.  The efforts of WYDOT on focusing HSIP projects on Safety

Emphasis areas of the Strategic Highway Safety Plan are indicating progress on driving down fatal and

serious injury crashes.

Describe any other aspects of the overall Highway Safety Improvement Program effectiveness on

which you would like to elaborate.  

WYDOT is completing projects targeted at the predominate crash type of run off the road.  The systemic

improvement projects are difficult to analyze as a direct contributing factor to the downward trend in

fatal and serious injury crashes in the State.

  

These type of projects are helping drive down the fatal and serious injury crashes because many times

we do not know where drivers will be impaired, distracted or fatigued while travelling on the system.

Glossary

5 year rolling average means the average of five individual, consecutive annual points of data (e.g.

annual fatality rate).

Emphasis area means a highway safety priority in a State’s SHSP, identified through a data‐driven,

collaborative process.  

Highway safety improvement project means strategies, activities and projects on a public road that are

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.
