摘要
交叉口的信号控制方法已经成为城市管理与控制的热点问题及重要组成,如何提高交叉口时空资源的利用率,最大化的挖掘城市道路通行潜力,成为现阶段城市道路交通研究的重中之重。对流量较大的大型平面交叉口设置综合待行区可以较明显地提高其通行能力、降低延误从而改善交通运行状况。通过精细化信号控制,在综合待行区设置主信号和预信号的控制模式,车辆在预信号的引导下可以提前通过首次停车线进入待行区,不停车的通过待行区驶入交叉口由路口,从而消除传统控制模式下放行造成的损失时间,降低了减速停车再加速过程中的油耗损失、尾气污染和刹车噪音,改善了空气质量。文章通过综合待行区的设置对交叉口车流进行精细化控制,不仅可以提高交叉口的通行能力,还解决了能源浪费和环境污染等问题。
Signal control at intersections has become a hot problem and significant component of urban management and control.How to boost the utilization of the time and space resources at the intersection and maximize the passage capacity potential of urban roads has become the urgent priority of urban road traffic research on this stage.Setting up comprehensive waiting area for high traffic at large intersection can obviously improve its capacity and reduce delay so as to improve traffic condition.By fine signal control,the control mode of main signal and pre signal is seting up in the waiting area.Under the guidance of the pre signal,the car can access the waiting area ahead of time through the first stop line.No stopping through the waiting area to access the intersection.Thus eliminating the lossing time caused by release in traditional control mode,so the fuel consumption,tail gas pollution and brake noise are reduced,and the air quality is optimized.In this paper,the traffic flow at intersection is refined control by setting up the waiting area,it not only improves the capacity of the intersection,but also solves the problems of energy waste and environmental pollution.
