Foreword

To further promote a safer transportation system, the Federal Highway Administration would like to share this new resource, "Integrating Road Safety into NEPA Analysis: A Primer for Safety and Environmental Professionals."

This primer presents an introduction to the topic of addressing safety as a part of the environmental analysis process, as directed by the National Environmental Policy Act (NEPA). 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 within a project scope. The primer highlights the opportunity and benefits of linking safety planning to the environmental analysis at every stage of the NEPA process.

To provide the reader a better understanding of what is discussed in this primer, several case studies have been included in the document. The case studies highlight noteworthy practices in integrating safety in to the NEPA process.

This primer will be of interest to the planners, environmental specialists, and transportation safety practitioners who are interested in learning more about how to incorporate scientific safety analysis into the environmental documents, in particular those in state departments of transportation, metropolitan planning organizations, and other organizations involved in the NEPA process.

Thank you for your efforts to integrate safety considerations into the comprehensive transportation planning and environmental process. Together we are saving lives and reducing injuries and crashes.

Sincerely yours,

Anthony T Furst
Acting Associate Administrator for Safety

16. Abstract

This primer presents an introduction to the topic of addressing safety as part of the environment analysis process, as directed by the National Environmental Policy Act (NEPA). 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 within a project scope. The primer highlights the opportunity and benefits of linking safety planning to the environmental analysis at every stage of the NEPA process. The primer contains the following sections:

  • Considering Safety Prior to the NEPA process;
  • 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 Mitigation.

Appendix A contains related resources, including links to on-line courses, tools, and research documents covering topics such as the basics of the NEPA process, road safety analysis, and safety countermeasure selection. Appendix B contains case studies illustrating best practices in incorporating safety into the NEPA process.
