车道占用对城市实际交通能力的影响与分析

Lane Occupied Effects on City Actual Traffic Capacity and Analysis

针对车道占用对道路的实际通行能力的影响,结合各种经验公式并且综合考虑各种实际因素的影响,求出事故发生至撤离期间该路段的实际通行能力.综合运用分析对比方法和交通波理论等方法对问题进行分析,建立交通波模型,得出了问题的相关结论.最后根据车流波动理论对车辆排队现象进行分析,同时利用集结波与疏散波的相遇推出集结波波速与排队长度的关系.结合信号灯对车辆排队长度的影响得到当车辆排队长度达到上游路口时所需的时间.

Aiming at the problem of the effects of lane occupied on city road capacity,combined with the experience formula and considering the effect of various factors getting the actual capacity of the Accident section. Comparative analysis method and the traffic wave theory methods are used to analyze the problem,Building traffic wave model to obtain conclusions. Finally,according to the traffic flow wave theory to analyze the vehicles queuing phenomenon. meanwhile,finding the relationship between aggregation wave and the queue length. combined the effects of signal lamp to obtain the required time when the vehicle queue length to the upstream intersection.
