摘要
研究的主要内容包括:信号灯控制道路交叉口红灯周期形成的排队车辆,在放行后不同车型的启动时间和不同车型组成的混合机动车流车头时距的分布研究;混合交通状态下机动车启动通过交叉口时受到干扰后的延误时间研究;利用上述研究成果对混合交通状态下交叉口排队车辆的放行绿灯时间进行估算。课题以现实交通数据为基础,通过统计分析结果最终建立放行绿灯时间估算表,对混合交通状态下道路交叉口信号灯的配时起到指导意义。
The start-up time and headway of queuing motor vehicles in the intersection, start-up lost time of through vehicles with disturbance under mixed traffic condition, and estimate of green time for discharging motor vehicles in the queue based on above results were analyzed. Based on real traffic data under mixed traffic condition, statistic values of start-up lost time and headway classification according to vehicle type were obtained. Using these values, green times for discharging vehicles in the queue were calculated, which can be applied in intersection signal control strategies.
