| 摘 要： | 减少辅路车流对快速路出口产生的影响有利于提高出口通行能力和保证快速路主路交通流的正常运行，对菱形立交先入后出式出口进行数据收集，利用该数据标定和验证VISSIM微观仿真模型。利用该仿真模型，通过仿真试验，分析了辅路车流运行状态对快速路出口交通流特性的影响。其结果可以为辅路车流的交通管理提供参考。

| Abstract: | Decreasing the impact on the urban expressway exit from the supporting road has an important role to increase the exit capacity and insure the normal operation of expressway An exit of diamond interchange with previous entrance and later exit is surveyed, and the traffic flow data is collected. VISSIM microcosmic simulation model is calibrated and validated through using the survey data. By means of using the simulation model and trials,the authors analyzed the impact on the traffic flow of urban expressway exit from the supporting road. The result may be the reference to manage the supporting road flow. |
