| 摘 要： | 将网络交通流模型、匝道控制模型、基于可变信息标志(variable message sign,VMS)的路径选择模型等整合为一体,建立了网络交通整合控制模型.与各种边界条件相结合,测试了匝道控制和路径诱导的控制效果.结果表明,无路径诱导有匝道控制策略的路网总时间消耗(total time spent,TTS)减少仅3%;有路径诱导无匝道控制策略的路网TTS减少20%,但入口匝道排队长度很不均衡,最大达300辆;有匝道控制有路径诱导策略的路网TTS减少20%,入口匝道排队长度比较均衡.

| Abstract: | Integrated network traffic flow model,ramp metering model and route choice model based on Variable Message Sign(VMS),and combined with various boundary conditions,this paper tested the effect of traffic control measures like ramp metering and route guidance on common bottlenecks.Test results show that in the strategy of ramp metering and no route guidance,the Total Time Spent(TTS) decrease only 3%;in the strategy of route guidance and no ramp metering,the TTS decrease 20%,but the queue length of ramp entran... |
