1. 1 ADOT Road Safety Assessment Program Presented to NACOG Technical Subcommittee December 4, 2013

2. 2 What is an RSA ? A Road Safety Assessment is a formal examination of user safety of a future or existing roadway by an independent, multi- disciplinary team. Proactive Field observation - day, night, peak, off-peak Multimodal - peds, bikes, ADA, transit, trucks, etc. Identify causes of driving errors Consider influence of adjacent facilities Focused on substantive safety

3. 3 RSA Process Road owner(s) submits request - http://www.azdot.gov/business/engineering- and-construction/traffic/traffic-safety/road-safety-assessments http://www.azdot.gov/business/engineering- and-construction/traffic/traffic-safety/road-safety-assessments Team is assembled RSA is conducted Formal Findings Report sent to owner(s) Owner(s) submits written implementation plan

4. 4 RSA Application

5. 5 4E emphasis Mitigation measures address crash "triggers" Mitigation measures include: Engineering Education Enforcement Emergency Response Crash “Triggers”

6. 6 Haddon Matrix

7. 7 Substantive Safety

8. 8 Emergency Response

9. 9 Holistic approach RSA Findings : reflect consensus of review team consider confounding issues: Feasibility, economic efficiency, affordability, practicality, political/institutional acceptability, legal compatibility, consistency, etc. focus on road user interaction address Human Factors and Human Behavior issues address roadway environment factors address observed conflicts and crash patterns improve safety of all road users

14. 14 RSA Report Documents the results of the RSA Identifies and prioritizes safety issues Includes suggestions for improvements

15. 15 Response Letter Prepared by the road agency (with possible input from designer) for each safety issue, identifies what action will (or will not) be taken with a brief explanation Becomes part of the RSA record
