摘要: 为了缓解日益严重的交通问题,寻求解决道路通行能力低下问题的有效方法,以提高道路利用率.本文通过采集英国3个路口和中国北京10个路口视频数据进行通行能力和饱和流量对比,分析中英差异和原因.在此基础上,定量分析非机动车对北京市交叉口绿灯损失时间的影响,以定量分析非机动车对信号交叉口通行能力和饱和流量的影响.对比结果表明:由于非机动车及行人干扰,中国城市道路交叉口道路利用率要比英国整体低10到20个百分点,这为解决中国城市道路利用率低的问题提供指导方向.最后,通过官园桥的实例,验证该研究成果的科学意义和应用意义.

Abstract: To ease the everworsening transportation problems, to find an effective way to solve the problem of low road capacity, and to raise the road utilization, the paper compares the traffic status of China and UK in terms of the traffic capacity and saturation flow. The video data of 3 intersections of UK and 10 of Beijing of China are collected and the difference and reasons are explored between China and UK. Based on that, the paper quantitatively analyzes the green time loss and the capacity and saturation flow of signalized intersections affected by nonmotor vehicles. Comparative results show that: road utilization of China’s urban road intersections is lower than that of the UK by 10% to 20% because of the interference from nonmotor vehicles and pedestrians. It provides references for solving the problem of low road utilization of China’s urban road intersections. Finally, the case study on Guanyuan Bridge of Beijing verifies the scientific and applied significance of this research.
