A large scale of field-test investigation was conducted in Beijing using Video Drive Recorder (VDR) which could record image front the vehicle. Fifty taxis equipped with VDR were used to collect data real traffic environments for a whole year and volume naturalistic driving including crashes near-crashes collected. This paper analyzed pre-event maneuvers drivers studied characteristics braking operations Conflict-prone drivers. Then an evaluation method proposed rate driver's accidents avoidance ability, evaluate relationships between brake behaviors accident rates. The results showed that most evasive within 2s before dangerous state. By comparing recorded by regarding Beijing, great similarities found type occurrence time them. According 100 rear-end near-crashes, if delayed 0.2s, 17% would have been crashes; forces decreased 0.1g, 33% crashes.
