TRAFFIC ACCIDENT FACTOR ANALYSIS BYQUANTITATIVE PERCEPTION-ACTION MODELOF DRIVERS

摘要

This study considers a case where a traffic accident occurs with a probabilitywhen a current driving pattern continues without any avoidance action like deceleration.The accident probability, which is objective in nature, is assessed subjectively by thedriver. An avoidance action is likely to be taken when the subjective probability exceedsa maximum acceptable value, whereas the current driving pattern continues otherwise.Such a driver model based on a perception of hazards and execution of avoidance action isproposed. Traffic accident prevention measures are then classified according to the eventtree derived from driver model.
