摘　　要：武警部队“处突”时,如何在不给城市正常交通带来很大影响的条件下,选择最优路径,在最短的时间内安全到达指定地点的问题值得研究。在分析连通可靠度的基础上,建立了最优路径选择的路段阻断风险效用函数及算法,并基于MapInfo平台,利用VB编程实现了最优路径选择。此外,还对如何通过控制红绿灯来代替传统的交通管制进行了探讨。对提高应急交通保障水平有一定作用。How to choose the optimal path for the CAPF to cope with the contingency without much affecting the normal urban traffic is a problem worth studying. The paper, on the basis of analyzing the connecting reliability, finds the avail function for choosing the optimal path based on the platform MapInfo by means of VB and realizes the algorithm. In order to accomplish the task successfully and reduce the influence on the urban traffic, the article probes into the use of the control of traffic lights instead of the traditional control of traffic.
