Integrating the HSM into the Highway Project Development Process

The Integrating the Highway Safety Manual (HSM) into the Highway Project Development Process guide 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.

Integrating Road Safety into NEPA Analysis

A new tool created by the Federal Highway Administration (FHWA) and the Transportation Safety Planning Working Group (TSPWG), Integrating Road Safety into NEPA Analysis: Practitioner's Primer, presents a brief introduction to the topic of addressing safety in the NEPA process. It presents practitioners with basic concepts for including meaningful, quantitative analysis of project safety issues and for taking advantage of the latest tools, research, and techniques for improving road safety. The primer is designed for NEPA practitioners who want to learn more about best practices for analyzing and addressing project safety issues during each stage of the NEPA process. It also is intended to help safety practitioners understand the basics of the NEPA process and where safety considerations can be incorporated.

The Primer is organized into easy-to-use sections that walk users through the steps to accomplish the integration. These steps include:

  • Considering Safety Prior to NEPA;
  • NEPA Overview and Levels of Documentation;
  • Public and Stakeholder Outreach;
  • Purpose and Need Statements;
  • Alternatives Analysis;
  • Defining the Affected Environment; and
  • Analysis of Environmental Impacts and Mitigations.

Further information is provided in the Appendices, including links to on-line courses, tools, and research documents, and several case studies describing best practice approaches used by several States.

FHWA and the TSPWG also developed a brochure that highlights the content in the Primer.
