Foreword

The Highway Safety Improvement Program (HSIP) Manual updates the 1981 HSIP User’s Manual (FHWA-TS-81-218) to reflect current law, regulations and new and emerging technologies and noteworthy practices regarding state and local highway safety improvement programs and related activities.  The HSIP consists of three main components that are essential to the success of the program:  planning, implementation and evaluation.

The process and procedures outlined in the Manual can be used by state agencies to administer the HSIP, as required by 23 CFR 924.  In addition, transportation planning organizations, as well as county and local government agencies can use the HSIP Manual to plan, implement, and evaluate highway safety improvement programs and projects that best meet their capabilities and needs.

For additional information, please contact the HSIP Team in the Office of Safety. We wish you continued success in implementing programs and projects to reduce the number of fatalities and serious injuries on our nation’s roadways.

Preface

The Safe, Accountable, Flexible, Efficient Transportation Equity Act – a Legacy for Users (SAFETEA-LU) established the Highway Safety Improvement Program (HSIP) as a core Federal-aid highway program.  SAFETEA-LU reinforced the need for strategic planning and data-driven decisions.  The Federal Highway Administration (FHWA) provided clarifying guidance to the States via updates to the Federal regulation that supports the HSIP (23 CFR 924).  However, these actions require additional guidance for state departments of transportation and local government agencies to implement programs that will achieve a significant reduction in traffic fatalities and serious injuries on public roads.

The Highway Safety Improvement Program (HSIP) Manual provides an overview of the HSIP and outlines procedures and tools to assist transportation professionals with the planning, implementation and evaluation phases of the HSIP.  The HSIP Manual was developed based on the latest research, as well as state and local practices, pertaining to roadway safety management processes.  Hyperlinks throughout the document connect the user to valuable resources to assist with their decision-making processes.  The HSIP Manual is a valuable tool and a comprehensive reference for state and local transportation safety practitioners working to advance the HSIP and other safety projects.

A technical oversight working group, consisting of Federal and state representatives, guided the development of the HSIP Manual.  The primary role of the working group was to review various aspects of the HSIP Manual for technical accuracy and recommend best practices and procedures to ensure the Manual meets practitioner needs.  Their gracious contributions and expertise will support the development of many life-saving programs resulting in fewer fatalities and serious injuries on our nation’s roadways.
