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 Vissim simulation model of mountainous two-lane highway maintenance work area was established. The running time of the vehicles under different closed section lengths was simulated by traffic light control passage time. The parameters of delay, queue length, parking times and percentage of parked vehicles were analyzed. The closed double-lane highway lanes in mountainous areas should not be closed more than 200 m in the short-term curing operation and less than 2 500 m in the long-term maintenance operation. This provides a theoretical basis for the setting of two-lane highway maintenance operation area and traffic organization.
