Pedestrian-Vehicle Conflict Model and Its Application in Pedestrian Crossing Street Risk Control

Abstract:

Basing on the traffic conflict technique and videotaping 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 validation is conducted to ensure the modeling confidence lager than 95%. In addition validation is used to prove that the conflict rate contributes to negative binomial distribution. The conflict probability model is therefore built. Calculating the pedestrian vehicle conflict control benefit and cost in the developed area in China, decision support method on conflict control is advised.
