Pedestrian Crossing Scenario Model Using Petri Nets

Pedestrian accident can be derived as a process of a combination from several elementary events. However, the understanding of the sequence of event in the pedestrian accident process is still less clear. It acquires the definition of event in the pedestrian crossing scenario at signalised intersections as an operational event that may lead to pedestrian accident. Thus, this paper gives an insight view of translating the sequence of event to model pedestrian crossing scenarios using Petri Nets approach. Qualitative data from site observation was extracted to draw the flow of events for the pedestrian crossing scenario. The developed model gives an understanding of the risky situation when pedestrian and vehicle are interacted at signalised intersections. Further analysis of this model is expected to give a potential risk value of pedestrian crossing. (C) 2014 The Authors. Published by Elsevier Ltd.
