摘要
机动车、行人以及非机动车往往是构成现代道路交叉口的主要元素。随着城市路网建设的不断扩大,交通秩序失衡及交通冲突等问题也随之增加。本文在对机动车、非机动车及行人流的自身特点进行分析的基础上,以排队车辆、延误为优化目标,提出混合交叉口交通信号配时优化方法,并基于实测数据运用交通流仿真软件对优化方案进行校验。结果表明,优化后的Webster信号配时方案可为混合交通信号交叉口设计提供基础理论支撑,为城市道路交通控制提供有效的控制方法支持。
Motor vehicles,pedestrians and non-motor vehicles are often the main elements of modern road intersections.With the continuous expansion of urban road network construction,problems such as traffic order imbalance and traffic conflict also increase.Based on the analysis of the characteristics of motor vehicles,non-motor vehicles and pedestrian flow,taking queuing vehicles and delay as the optimization objective,the optimization method of mixed intersection traffic signal timing is proposed,and the optimization scheme is verified by traffic flow simulation software based on the measured data.The results show that the optimized Webster signal timing scheme can provide basic theoretical support for the design of mixed traffic signal intersection and effective control method support for urban road traffic control.
