一种高速公路交通流密度模型及其应用

An Expressway Traffic Flow Model and Its Application

根据等价速度描述所存在的问题 ,提出一种指数等价速度的模型。该模型考虑了整体车流的行为而不仅仅是单个车流的总合 ,使模型描述更为合理。仿真和实际计算表明 :使用该等价速度模型 ,可以大大降低车辆速度调节的冲击量 。

An exponential equivalent speed model is introduced by the authors,based on the existing problems in description of the equivalent speed Overall traffic flow behaviour is taken into consideration rather than combination of individual vehicel flow,making it more appropriate in description It is shown that the equivalent speed model is practical for use in vehicle speed regulation
