Improving Urban Traffic Evacuation Capability in Emergency Response by Using Smart Phones
This article presents a social network based methodology for improving urban traffic evacuation capability in emergency response by using smart phones.Considering destructive and unexpected characteristics of natural hazards or man-made disasters,the effected people cannot evacuate efficiently when they face the unknown impacts of these events.Therefore,a smart phone application,called EMAPP,is developed to tackle this difficulty.An overall description including design architecture and system modules is provided.Optimal shelter choice strategy is given by using the modified Dijkstras algorithm.The Nagel-Schreckenberg model loaded by vehicle arrival rate is implemented to produce the spatio-temporal diagrams of the vehicles.Both traffic congestion and cascading failure during real-time emergency evacuation are analyzed.The main issues are devoted to link the affected people,geographic information and traffic conditions through the smartphone application.Therefore,in emergency evacuation,the affected people can receive mutual help and urban resilience can be enhanced.
