城市高架道路下匝道车流插入机制的Markov链模型

A Markov chain model for traffic flow on off-ramp of city freeway

通过分析城市高架道路下匝道车流与地面车流相互影响的规律,引入随机动态系统,建立了时间齐次的M arkov链模型,能对各车道的车辆“顺畅驶入”、“以某概率驶入”、“减速停车等待”作实时预报,揭示了地面车流与下匝道车流相互影响的机制。

According to the characteristics of traffic flow on off-ramp of city freeway and on the land paths, a dynamic stochastic system is introduced in this paper. In addition, a Markov chain model is proposed. In this model, an approach is given for real-time prediction of the traffic flow on off-ramp of the city freeway.
