【摘要】：为了均衡同一进口内直行和左转车流的饱和度,使单进口放行方式的通行效率和时空资源利用效率更高,阐述了基于效用理论与车流临界模型的直左合用车道的设计方法,根据对山东济南无影山中路-黄岗路交叉口的实地调查,运用Webster延误模型分别来求单进口放行方式下设置直左合用车道和没有设置直左合用车道情形下的总延误。结果表明:单进口放行方式下设置了直左合用车道放行效果更好。
[Abstract]:In order to balance the saturation of the straight and left turn flow in the same inlet and make the single inlet release mode more efficient in traffic and the utilization of space-time resources, the design method of the direct left combined lane based on the utility theory and the critical model of the vehicle flow is described. Based on the field investigation of the intersection of Wuyingshan Middle Road and Huanggang Road in Jinan, Shandong Province, the Webster delay model is used to calculate the total delay in setting up the direct left combined lane under the single inlet release mode and in the case of no direct left combined lane. The results show that it is better to set the straight and left combined lane under the single inlet release mode.
