【摘要】 文章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所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,以及利用上述研究成果提出的混合交通状态下提高道路交叉口通行能力的合理化措施及其仿真结果。目前基于混合交通状态下提高城市道路交叉口通行能力的相关研究与分析较少,缺乏针对可执行合理化措施的深入研究与分析。课题以现实交通数据为基础,通过排队车辆在放行后不同车头时距的统计分析结果研究提高城市道路交叉口通行能力的相关措施,并给出措施执行前后的仿真结果对比分析,具有较强的实际应用价值。更多还原

【Abstract】 The contents of this paper include 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, measures for enhancing capacity at signalized intersections based on above results and simulating results after adopted these measures. Previous research about passing capacity of urban intersections under mixed traffic condition did not obtain reasonable and effective plans for improving capability. In this paper, based on real traffic data under mixed traffic condition, statistic values of start-up lost time and headway classified according to vehicle type are obtained. Using these values, signalized intersection’s capacity can be analyzed deeply, some appropriate measures for increasing capacity can be discovered, and efficiency of these measures can be proved through simulations. Obtaining results and recommending methods in this paper are useful for traffic engineering.更多还原
