摘　　要：针对高速公路应急资源调度方案缺乏考虑瓶颈路段交通流特性,导致调度用时较长的问题,研究一种考虑瓶颈路段交通流特性的高速公路应急资源双目标调度方法。利用尖点突变理论模型分析瓶颈路段交通流特性,以路径最短和时间最少为目标设置双目标函数;利用混合蛙跳算法求解目标函数,输出高速公路应急资源调度方案。测试结果表明,所研究方法在保证所用总时间最少的前提下,求解的调度方案路径总长度相对较短,具有较好的实际应用效果。The highway emergency resource scheduling plan lacks of considering the traffic flow characteristics of bottleneck sections,which leads to longer scheduling time,hence,a bi-objective scheduling method for highway emergency resources which considers the traffic flow characteristics of bottleneck sections is studied.Using the cusp mutation theoretical model,this paper analyzes the traffic flow characteristics of the bottleneck section,sets the bi-objective function with the shortest path and the least time as the objectives,and uses the hybrid leapfrog algorithm to solve the objective function and output the highway emergency resource scheduling plan.The test results show that the path of the scheduling plan solved by the studied method is relatively short under the premise of guaranteeing the total time used is the minimum,and the total length of the path is relatively short,which has better practical application effect.
