Abstract:

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.

Key words: engineering of communications and transportation system, intelligent transportation systems, emergency evacuation, quasiuser optimum dynamic traffic assignment, route selection, fast optimum algorithm for K-shortest paths
