摘　　要：城市快速公路接入车辆对主线车辆有重要影响。由于缺乏对城市快速公路上接入口的管理,导致城市快速公路的运行速度减慢、运行效率远小于预期水平。对无控接入口与相邻大型信号路口的接入间距进行探讨,将整个车辆运行过程分为车辆汇入,识读标牌,车辆交织及车辆排队四个部分,根据不同过程中车辆的运行特征提出了相应的指标或计算方法,并将其汇总得出适宜的接入间距。Due to the lack of the management of the urban freeway,the travel speed become slower and the operational efficiency is far less than expected,which shows the importance of the access vehicles to the mainline.The distance between uncontrolled access and adjacent signal intersection was discussed. The whole process was divided into vehicle merging,understanding sign,weaving and vehicle queuing. Based on the vehicle＇s characteristics of different process,the relevant indexes and calculation methods were provided,then the proper access distance was summarized.
