Study on the Optimal Path of Resource Attemperment for Urban Transportation Emergency Events

Targeting urban traffic unconventional emergencies， under the condition that a“save point”， and“emergency point”have been given， this paper studies the problem of optimal path of emergency resource scheduling under the multi-objectives. It first describes the problem， and then constructs the optimization model for optimal path selection in emergency resource scheduling of the shortest settling time and minimum cost. Meanwhile， the optimal program is given by referring to an improved ant colony algorithm together with the improved TOPSIS method. At last， this paper proposes a simulation example.
