兀型路口信号灯时间设置优化问题
The Time Setting Optimization Problem of Signal Lights of π Type Intersection
摘要: 本文依据“车流平均流量”、“安全过马路需要的最低限度时间”等因素,通过数据收集和数学分析,建立合理的兀型路口数学模型。通过数学模型,对兀型路口红绿灯时间设置进行分析,从而计算出信号灯的最优时间设置,提出改善方案,以此在最大程度上减少车辆等待时间,从而缓解车辆拥堵状况。
Abstract:
Based on the “average flow of traffic”, “minimum time required for safe crossing the road” and other factors, through data collection and mathematical analysis, we establish a reasonable mathematical model of the π type intersection. Through the mathematical model, the time setting of the traffic lights of the π type intersection is analyzed to calculate the optimal time setting of the signal lights and to propose the improvement plan, so as to reduce the vehicle and pedestrian waiting time to the maximum extent, and then, alleviate the congestion situation of the vehicle.
