高速公路主线收费站缓堵管控技术研究

Study on the Technology of Ease Congestion Control in Main Line Toll Station of Highway

随着车辆数量的不断增加,交通拥堵频发,尤其是主线收费站,不仅造成大量的时间延误,而且频繁的车辆启动与制动使得油耗增大,尾气排放量急剧增加,对环境造成污染。为了提高道路的经济性,实现节能减排的目的,通过实地调研,以交通工程学、控制论等为基础,采用数理统计法分析高速公路收费站停车间距、服务时间等交通流特性,通过构建排队系统模型,建立了车流控制系统,并确定了车流控制系统参数,运用VISSIM仿真验证了控制系统效果良好,为道路拥堵的解决提出新的研究思路。

With the increasing number of vehicles, traffic congestion often occurs, especially in main line toll station. Traffic congestion caused a lot of delays and frequent starting and braking of the vehicle so that the fuel consumption increases,a sharp increase in exhaust emissions, causing environmental pollution. In order to improve the economy of the road and achieve the purpose of energy saving and emission reduction,the parking distance, service hours and other traffic flow characteristics in highway toll station were investigated, and analyze the data with mathematical statistics based on traffic engineering and cybernetics. Then a queuing system model is build to establish a traffic control system, and then determined the traffic control system parameters. At last, a VISSIM simulation is used to verify that the control system is effective and that research provide a new idea to solve road congestion.
