| Abstract: | To improve the efficiency of emergency rescue and evacuation,this paper introduces an emergency route planning algorithm based on dynamic traffic assignment.Different from existing static route planning algorithms,the algorithm takes the dynamic and systematic characteristics of the problem into consideration.First,a dynamic traffic assignment model through traffic simulation is given.Then,the steps of the algorithm are explained.Finally,the algorithm is tested by using Beijing road network data.The results prove the feasibility and effectiveness of the proposed algorithm. |
