Conflict Model of Evacuees and Vehicles on Pedestrian Crossing in the Aftermath of Disaster
Simulation which focuses on conflict between pedestrians and vehicles is important to assess evacuation safety of the pedestrians and drivers of the vehicles at a disaster. Although there were many researches in regular traffic conditions, conflict in the aftermath of disaster has not been discussed enough. Griffiths et al. developed a microscopic simulation model of pedestrians and vehicles on an unsignalized zebra crossing. In this contribution, we attempted to modify the conflict model of Griffiths et al. and applied it to a zebra crossing and an event of a tsunami evacuation drill. In the model proposed, we made assumptions that pedestrians are more reckless to cross a street in an emergency. As a result, it was found that the conflict model which takes into account the hypothesis about psychological state of pedestrians reproduced well the results of a field survey.
