An Optimal Traffic Dispatching Strategy with Uncertain Evacuees’ Behaviors under Emergency Evacuation Situation

An optimal traffic evacuation scheme is of practical importance to transport all the evacuees in potential minimized evacuation time under an emergency. In this paper, we develop a traffic dispatching control strategy under uncertain evacuees’ behaviors, which consists of three parts of buses in every round as gathering, waiting, and transporting times. From the time that the disaster occurs to the time when all evacuees transport to safe shelters, the buses will be dispatched to minimize the maximal time of a bus in evacuation. A new algorithm is designed to solve the two-stage optimization process, and the simulation results demonstrate the effectiveness of the proposed method.
