NCHRP Synthesis 20-05/Topic 54-03 [New]

DOT Practices on Road Safety Audits
[ NCHRP 20-05 (Synthesis of Information Related to Highway Practices) ]

  Project Data
Funds: $55,000
Authorization to Begin Work: 4/29/2022 -- estimated
Staff Responsibility: Trey Joseph Wadsworth
Fiscal Year: 2023

Preliminary Scope

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.

 

Information to be gathered includes (but is not limited to):  

·       Frequency, quantity, and the purpose of DOT RSAs;

·       Contexts for where RSAs are conducted (rural, urban, corridors, intersections, and interchanges);
·       Growth, decline, or non-use of RSAs;
·       Changes in RSA processes, reporting, or focus (e.g., speed management/target speed and vulnerable road users);
·       Role of RSAs in DOT highway safety programs or other implementation mechanisms;
·       Supporting materials developed by DOTs such as manuals, checklists, or procedures;
·       Consideration of active transportation, micro-mobility, equity, and new technologies (e.g., LED lighting’s widespread adoption since 2003); and
·       Research gaps related to RSAs.
 
Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
