交叉口禁止变换车道线长度计算方法

摘要

traffic engineering; intersection; vehicle queuing; marking with lane changing prohibited; queuing theoryThe calculation procedure includes the collection of traffic data, conversion of traffic volume, calculation of the number of queuing vehicles and the average queuing length. A real example is then given to make a comparison with the existing method. The computational result shows that the method discussed in this paper is more reasonable and the resulted length accords with the practical requirements.%基于排队理论,提出一种以等候信号放行车辆排队的平均长度为依据来计算交叉口进口道禁止变换车道线长度的方法,包括交通数据的采集、交通量的换算、排队车辆数的计算以及平均排队长度的计算,并结合具体实例,与根据现有方法计算得到的结果进行比较.
