Presentation Overview
• What is crash typing?

Crash Typing• Traditional crash data provide where, when
and whom facts about ped and bike crashes

peds and bikes

typing ped and bike crashes– Update/refine the definitions of the 1970’s – Provide links between crash types and potential
countermeasures– Provide limited report capability
