What is a Road Safety Audit?What is a Road Safety Audit?
A road safety audit is aformal safety performance examination
of an existing or future road or intersection by an independent multi-disciplined audit team.

What is a Road Safety Audit?What is a Road Safety Audit?
Formal: Procedures and documentation
Safety performance: Focus on safety
Independent: Auditors detached from project team
Audit team: General experience and specialists

A road safety audit also…A road safety audit also…
Considers the safety of all road users
Examines the interaction of project elements
Considers interactions at the borders or limits of the project
Proactively considers mitigation measures

A road safety audit is NOT….A road safety audit is NOT….
… a standards check, examining adherence to design guidelines.
… a backdoor to redesign the project.

What is a Road Safety Audit?What is a Road Safety Audit?
A road safety audit seeks to identify opportunities to improve safety

Field ReviewField Review
Observe road user characteristics
Observe surrounding land uses
Observe link points to the adjacent transportation network
Look for:– driveway issues– roadside hazards– sight distance
obstructions– Anything impacting safety

Field ReviewField Review
Consider all users
Consider driver behavior
Drive the site
Drive all approaches
Make all turns
Walk/bike the project area
Take notes
Take lots of photos

RSA Analysis: Conducting the RSARSA Analysis: Conducting the RSA
Workshop setting
Review background reports, crash data, and design criteria
Systematically review design drawings and/or other information
Identify, prioritize, and mitigate safety issues
![Page 18: December 5, 2011 Presented by: Sue DAgnese Region 1 Traffic Manager Overview of: ROAD SAFETY AUDIT (RSA) PROCESS & APPLICATIONS TV Highway at 185th Ave](https://reader036.vdocuments.us/reader036/viewer/2022062511/55157cee55034691418b54b1/html5/thumbnails/18.jpg)
Risk AnalysisRisk Analysis
For each issue:– What potential exists for crashes?– What is the likelihood of crashes?– How severe are the crashes likely to be?
Crash potential? – What exposure exists
Likelihood of a crash?– What probability exists
How severe? – What consequences?
Risk = f (Exposure, Probability, Consequences)

Benefits of an RSABenefits of an RSA
Consensus on the problems
Focus for project development teams
Looked at safety improvements that we might not have otherwise identified
Reality check on some design items
All alternatives and safety trade-offs are prioritized
Low cost improvements identified
Improved transportation safety for all users
