Abstract :
The road network emergency evacuation means evacuating the traffic flow which is trapped to safer areas as immediately as possible, in order to bring the least impact and destruction by emergent catastrophe events. As the critical issue in emergency evacuation, aiming at the shortest evacuation time, we build a route selection model in emergency evacuation based on quasi-user optimum dynamic traffic assignment theory, and develop a constrained K-shortest paths algorithm within a dynamic restricted searching area. Efficiency and feasibility of the model and algorithm are proved by the simulation results.
