  dynamic traffic flow
Dynamic traffic flow modeling has captured the focus of many researchers in the transportation area.
      
The approach is very generic and can be applied to automatically calibrate different dynamic traffic flow models.
      


Usually The static model is often used when the traffic assignment problem is discussed. This paper studies a dynamical traffic assignment. Through its corresponding mathematical model the properties of the dynamical traffic flow in a traffic network are analysed when it approaches equilibrium solution, when different equilibrium solutions are transformed, the effect of the time is discussed.

人们以往在讨论交通分配问题时,往往使用静态模型。本文考察了动态交通分配过程,通过其相应数学模型,分析了动态交通流在接近均衡解时的特性以及不同均衡解之间转换时的时间效应。

This paper, on the base of basic dynamic model and through the modification of the speed equation presents an extended dynamic model of freeway traffic to describe a complex traffic flow such as that on inner urban freeways and improve the accuracy of traffic analysis and control system design. The author has accomplished modeling and simulating for a real freeway. The results show that in cases of inhomogeneous topologies with lane'droping or high on-and off-ramp volumes the basic model has significant deviations...

This paper, on the base of basic dynamic model and through the modification of the speed equation presents an extended dynamic model of freeway traffic to describe a complex traffic flow such as that on inner urban freeways and improve the accuracy of traffic analysis and control system design. The author has accomplished modeling and simulating for a real freeway. The results show that in cases of inhomogeneous topologies with lane'droping or high on-and off-ramp volumes the basic model has significant deviations whereas the extend- ed model has a satisfactory accuracy. Besides, this paper also discusses the modeling pro- cess, model validation and simplification.

本文在高速公路交通流基本动态模型基础上对平均速度模型加以修正,提出一种改进模型,以期更精确地描述某些复杂道路如城市高速公路的动态交通流,提高交通分析和最优控制设计的精度。作者对一条道路进行了动态交通建模及仿真研究。结果表明,当存在较大的匝道流量冲击或沿途车道数目有改变时,基本模型的误差较大,而改进模型的精度有明显提高。文中还讨论了建模方法、模型检验及模型简化等问题。

This artiele dcals with the model of frceway traffic flow. We set up in this article the nonlinear-dis-crete-dynamic traffic flow model and optimization analysis model of freeway traffic flow.We also created two kinds of optimization objeetive functions in dctail at rush hours and non-rush hours, and diseussed the teehnique of parametric inference in the models.At last,We calculated actually freeway states from Xian to Ling tong both at rush hours and non-rush hours.

本文对高速公路进行了两级分段,以车流密度ρ(k)和主流速度v(k)作状态变量,将人口匝道车流量ri(k)作控制变量,建立高速公路非线性离散动态交通流数学模型和交通流优化模型,提出了模型中参数辨识的优化算法,分别建立了高峰期和非高峰期两种情况优化目标函数,最后,实际计算了西(安)临(潼)高速公路高峰期和非高峰期的优化状态.
