A large number of fatalities are caused by the vehicle-pedestrian accidents. It is a surrogate method in pedestrian protection and active safety improvement to analyze the traffic conflict between vehicles and pedestrians. Basic definitions of vehicle-pedestrian conflict have been introduced with the descriptions of the methodologies for behaviour measurement and field data collection. By video recording and image processing, the data series of road users’ trajectories on the urban crosswalk were studied in two conflict situations between drivers and redcrossing pedestrians. The conflict measurement (Time-to-Collision) and drivers’ deceleration choice were statistically analyzed. The driver speed performance in the evasive process related to the spatial variation has been investigated and the situational factors influencing drivers’ yielding behaviour has been determined by the model proposed based on the binary logit model which was validated to predict the driver decision accurately. The research results would hopefully lay the groundwork in the target of modeling driver behaviour under various conflict situations and be helpful for the design of driver assistance systems.
