Optimal Path Selection under Emergency Based on the Fuzzy Comprehensive Evaluation Method.

When emergency occurs, the city is vulnerable, city is the region of high concentration of population and economic activities, and the traffic system is the lifeline of urban disaster prevention and mitigation, it is material transportation channel, and it is the path of personnel evacuating, sending rescue personnel and engineering team, delivering relief supplies under emergency situations. The occurring of emergencies in addition to direct serious damage of transportation infrastructure, casualties and economic losses, it also make troubles for sending rescue workers, carrying relief supplies and disaster relief and emergency triggering of engineering team because of the stagnation of vehicles and interrupt of roads, it will trigger more indirect lose. In reaction to the phenomenon, this paper proposed an optimal route choice model under the emergency based on AHP-fuzzy comprehensive evaluation method, This article proposed algorithm based on fuzzy comprehensive evaluation algorithm, combining hierarchy analysis method (AHP), make the calculated conclusion more reliability and accuracy. By simulation show that the proposed algorithm based on AHP-fuzzy comprehensive evaluation method has higher accuracy compared with the general algorithm, it is more accord with people's demand for path under emergency conditions.
