| 摘 要： | 以高速道路为研究对象，概述了宏观交通模型的基本方程，提出了一种基于宏观交通模拟的路径行程时间预测方法．预测方法以宏观模型输出的速度为基础计算路径行程时间，能够考虑交通拥堵以确保行程时间预测结果更合理．预测方法包含一般计算方法、由路段行程时间合成的方法（近邻组合法）这两种计算方法，后者用以加快计算速度，确保预测能够适用于较大规模路网．算例分析说明了预测方法的有效性．

| Abstract: | Individual travel time is key paraeter for driver information systems and rerouting strategies.The paper presents a macroscopic traffic model based travel time prediction method for freeway networks.The method has three main features: travel time calculation is based on the time-dependent speed profile provided by macroscopic model,congestion(caused by bottlenecks or incidents) is properly considered in deriving related equations,the method includes two components,the general calculation approach and the ne... |
