Synthesis of Information Related to Highway Practices. Topic 54-03. DOT Practices on Road Safety Audits

A Road Safety Audit (RSA) is a proactive and formal safety performance examination of an existing or future road or intersection by an independent, multidisciplinary team. It qualitatively estimates and reports on potential road safety issues and identifies opportunities for improvements in safety for all road users. RSAs were introduced in the United States in 1997 following a Federal Highway Administration (FHWA)-sponsored scanning tour of Australia and New Zealand investigating safety management systems in 1996. NCHRP completed Report 336: Road Safety Audits in 2004. The report found that seven state departments of transportation (DOTs) were using RSAs in their safety programs. Since then, DOTs have been developing their resources, procedures, and practices for RSAs; information is scattered, and new considerations have emerged for conducting RSAs. They may include but are not limited to active transportation and micro-mobility growth. The objective of this synthesis is to document state DOT current practices related to RSAs.
