| 摘 要： | 城市快速路出口附加车道及其渠化长度的合理设置对于提高出口通行能力和减少出口对快速路交通流的影响具有重要的意义。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，建立城市快速路菱形立交出口仿真模型。通过仿真试验，对其结果分析得出城市快速路菱形立交出口附加车道长度及其渠化长度建议值。

| Abstract: | The rational length of auxiliary lane and channelization of urban expressway exit have an important role to increase the exit capacity and decrease the influence to expressway traffic flow from exit.The previous entrance and later exit style exit of diamond interchange have been surveyed,and the traffic flow data has been collected.VISSIM microcosmic simulation model is calibrated and validated through using survey data,and the exit of diamond interchange simulation model is built.Through using simulation trial,the author has analyzed the trial result and worked out the recommendation value of auxiliary lane and channelization length of urban expressway exit. |
