Since the publication of the first edition of the Highway Safety Manual (HSM) in 2010, many helpful resources have been developed to guide and support agencies with the implementation of HSM practices. A selection of these resources is provided below.
The Leading Practices in the Use of the HSM for Planning, Design, and Operations report, published in 2018, is intended to help state transportation agencies that have not yet begun to implement the HSM, are beginning to implement the HSM, or are looking to further enhance the implementation of the HSM within their agencies. Most of the recommended actions are also applicable to local transportation agencies and metropolitan planning organizations (MPOs) in similar situations regarding HSM implementation.
The report includes a selection of recommended actions and best practices for effective implementation and integration of the HSM, and covers seven areas of interest:
Additionally, as a part of the scan, a slide deck was created which summarizes the findings of the HSM domestic scan.
The Highway Safety Manual User Guide is a companion document to the HSM, developed under the Lead States Initiative (NCHRP 17-50) in 2014. The Guide was designed to support and provide examples and best practices for practitioners as they work to implement HSM practices. Designed and written primarily for analysts with basic knowledge of the HSM and basic to moderate knowledge of highway safety analysis procedures, it also contains insights that are useful to all practitioners.
The guide includes three major sections:
Additionally, as part of NCHRP 17-50, a series of Peer Exchange Reports, Technical Briefings, and a webinar on the implementation of the HSM were created. These documents can be accessed through the links below.
Peer Exchange Reports
The Integrating the HSM into the Highway Project Development Process guide, published in 2012, provides information for state and local practitioners on how to integrate the HSM into their project development process. Each section provides an overview of some of the implementation opportunities for the HSM during each stage of the project development process. The HSM, integrated into agency processes and considerations, will support regional, state, and national fatality reduction goals alongside the goals of mobility, the environment, and other competing needs.
The Implementation Guide for Managers, published in 2011, is intended for managers of DOTs charged with leading and managing agency programs impacting the project development process and safety programs. This guide is based on lessons learned from early adopters of the HSM, and outlines what the HSM is (and is not), how it relates to other core technical documents and policies, and the potential benefits of its use.
The guide includes three sections:
The Federal Highways Administration (FHWA) has developed brief case studies of effective applications of HSM practices by five different state departments of transportation.
Additional resources for implementation of the HSM are available from FHWA at the following locations.
