摘　　要：为了寻求两相位交叉口最佳的过街方式,文章就交叉口人均延误和交叉口车道通行能力两个方面展开研究,基于三种非机动车过街方式下的延误模型、车道通行能力模型,以人均延误和通行能力为判别指标,对比三种非机动车过街方式的交叉口人均延误和交叉口车道通行能力,取延误最小者或车道通行能力最大者为最优非机动车过街方式。具体应用中,以南京市两相位交叉口的调查流量为基础,计算出不同时段下延误最小的非机动车过街方式和交叉口车道通行能力最大的非机动车过街方式。结果表明:停车线后移方式下的交叉口车道通行能力最大,交叉口延误需要根据时段流量来确定最小延误对应的非机动车过街方式。研究可为选择合适的非机动车交叉口过街方式提供参考借鉴。To find the best way for non-motor vehicles to cross the street at two-phase intersections,this paper studies the per capita delay and lane capacity of intersections with three kinds of non-motor vehicle crossing modes.Based on the delay model and lane capacity model under three non-motor vehicle crossing modes,this paper compares the per capita delay and lane capacity at intersections of three non-motor vehicle crossing modes.The optimal non-motor vehicle crossing mode is the one with the minimum delay or the maximum lane capacity.In the specific application,based on the investigation flow of two-phase intersections in Nanjing,the non-motor vehicle crossing mode with minimum delay and the non-motor vehicle crossing mode with maximum lane capacity at intersections were calculated in different time periods.The results show that the lane capacity at the intersection is the maximum when the lane moves back after the stop,and the non-motor vehicle crossing mode corresponding to the minimum delay at the intersection should be determined by the flow of the time period.The paper can provides reference for choosing the proper non-motor vehicle crossing way at intersections.
