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 RSA Process Road owner(s) submits request - and-construction/traffic/traffic-safety/road-safety-assessments 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 RSA Application
5 4E emphasis Mitigation measures address crash "triggers" Mitigation measures include: Engineering Education Enforcement Emergency Response Crash “Triggers”
6 Haddon Matrix
7 Substantive Safety
8 Emergency Response
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
