| 摘 要： | 以北京市快速环路系统为研究对象,以大量的实测交通数据为基础,分析了流量-密度-速度三者之间的关系,据此来研究北京市快速环路交通流的运行特征;并利用不同的流密度模型进行相应的拟合,从而对各模型的适用范围和使用程度进行了对比分析,为进一步进行北京市快速路交通流特性的深入研究以及进行交通控制优化提供了基础。

| Abstract: | Taking the Beijing expressway system as the study object,the paper analyses the relationship among volume,density and speed,with massive measured data.On this basis,the traffic flow characteristic of Beijing expressway is appointed by fitting the data under different q-v-k models.Besides,the application of these models are also contrasted in this paper to provide references for the further research of Beijing expressway flow and the optimization of traffic management in Beijing. |
