公路行驶时间与交通流量预测的时间传递模型

以高速公路行车时间和交通流量预测为研究对象,建立了行车时间预测和路段交通流量估计的时间传递模型,得到了车辆从任意时刻进入高速公路的行驶时间。并分析了增加传感器处交通流量观测值情况下公路的通行特性,重点讨论了对局部阻塞路段的运行时间和交通流量的影响,利用交通流量时间传递模型,给出了该路段车辆运行时间和交通流量的精确预测。

Time-Transmitted Model for Forecasting Highway TravellingTime and Traffic Volume

This article is intended to forecast highway travelling time and traffic volume.It sets up a time-transmitted model for the forecast of travelling time and estimate of a section of a highway traffic volume,and get the travelling time whenever the vehicle get into the highway.In this article we also discuss the highway's passing characteristic in the situation of increasing the traffic volume observing statistic in places.We give an emphasis on the discussion of the influence on the travelling time and traffic volume in the partial plugged condition,and give a precise estimation of the travelling time and traffic volume via this time-transmitted model.
