摘要 建立山区双车道公路养护作业区Vissim仿真模型,通过信号灯控制通行时间,模拟在不同封闭段长度下车辆的运行状态,对行程延误、排队长度、停车次数和停驶车辆百分比等参数进行分析,得出山区双车道公路单车道封闭,短期养护作业封闭段长度不宜大于200 m,长期养护作业封闭段长度不宜大于2 500 m,这为山区双车道公路养护作业区设置和交通组织提供理论依据。 The simulation model of maintenance area for two-lane highway in mountain area was established based on Vissim. The model can simulate vehicles' running state with different lengths of blocked road section through signal lamp controlling time, and can analyze parameters such as trip delay, queuing length, number of stops and the percentage of suspended vehicles. The result shows that the blocked single-lane section length for short-term maintenance of two-lane highway in mountain area should be less than 200 m and that for long-term maintenance should be less than 2500 m. It provided a theoretical basis of setting maintenance area and transportation organizations for two-lane highway in mountain area.
