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 article presents a dynamic prediction system for an interurban mo-torway network.The system forcasts traffic conditions on the network in real-time,and provides information to a motorway traffic control centre. The models re-ceive traffic data such as traffic flow, average speed and detector occupancy in real-time from a motorway monitoring system,Additionally,a databank of historic traf-fic information will be used. The system contains several submodels:a statistical state space model for fil-tering noisy data,and for very short prediction(prediction horizon:5~15min);a dynamic traffic assignment model for short term prediction(15~60min );a real-time O/D matrix prediction model to provide the input flows to the statistical and assignment models. Predictions from the two models are merged where their re-spective time horizons overlap.

本文介绍一城市间高速公路网的动态交通预测模式系统。该系统实时预测网络的交通状况并把信息及时传送给交通控制中心。模式实时接受来自交通监测中心的交通流、平均速度及传感器占有率等交通数据。此外,模式也使用已有交通信息的数据库。模式系统主要由三个子系统组成:统计空间模式、动态加载模式和实时预测模式。子系统一用于过滤不稳定的交通数据并作出极短时间内的交通预测(5~15分钟);子系统二用于短时间内的预测(15~60分钟);子系统三则给前两个子系统输入流量。主系统综合各子系统的结果并作出交通预测。
