摘　　要：基于VISSIM仿真,通过经典优化方法,使成本函数最小,对城市道路养护施工作业区长度优化进行了研究。通过对养护作业区长度优化理论的阐述,分析了多车道高速公路养护作业区长度优化方法,按照作业区长度优化理论,采用VISSIM仿真方法,对双向四车道情况进行工作区长度优化的推导计算,在非高峰交通量下,当Q1=1 005辆/h时,养护工作区长度为1. 46 km时,最小综合费用为81 661元/km。在养护施工放向交通流Q1=2 005辆/h时,养护工作区最佳长度为0. 35 km,最小综合费用为621 124元/km。In this paper,based on VISSIM simulation,the cost function is minimized by the classical optimization method,and the optimization of the length of urban road maintenance operation area is studied.Through the elaboration of the length optimization theory of maintenance operation area,the length optimization method of multi Lane expressway maintenance operation area is analyzed.According to the length optimization theory of operation area length,the VISSIM simulation method is adopted to calculate the length optimization of the working area of the two-way four lane.Under the non peak traffic volume,the large Q 1 is 1 005 vehicle/h.When the length of the maintenance workspace is 1.46 km,the minimum comprehensive cost is 81 661 yuan/km.The best length of the maintenance work area is 0.35 km and the minimum comprehensive cost is 621 124 yuan/km when the Q 1=2 005 vehicle/h is transported to the traffic flow.
