PedestrianVehicle Conflict Model and Its Application to Pedestrian Crossing Street Risk Control

Abstract:

Based on the traffic conflict technique and videotape of 5 uncontrolled pedestrian crosswalk for 61 timing sections, this paper establishes the pedestrianvehicle conflict model and severe conflict model with the variables of traffic volume, vehicle speed and pedestrian volume.T and F tests ensure the modeling confidence to be over 95%. In addition,χ2 validation is conducted and proves that the conflict rate subjects to negative binomial distribution.The conflict probability model is therefore built up.The pedestrian vehicle conflict control benefit and cost in the developed area in China are calculated,and the decision support method on conflict control is advised.

Key words:pedestrian safety; pedestrian vehicle conflict; conflict prediction model; conflict controll
