低速混合型城市交通的流体力学模型

A FLUID DYNAMICS MODEL FOR THE LOW SPEED TRAFFIC SYSTEMS

  • 摘要: 本文提出了一种新的交通流数学模型,它比目前常用的交通流模型更具有一般性,尤其适用于我国城市现阶段低速混合交通为主的实际状况。讨论了模型的连续形式和离散形式,定解条件的提法,模型参数的测定方法,以及数值解的稳定范围。几个实际的、难度较大的算例,显示这种模型具有良好的数值模拟功能。

     

    Abstract: This paper presents a new mathematical model for traffic flow.The modelis more general than any one,which is widely used in traffic engineering,especially forthe city traffic cases in our country,in which vehicles run at low speed and together withbicvcles,We discussed both differential and difference formulations of the model.the initialand boundary conditions,model parameter identification method and the stabilities of thenumerical solutions.Several practical and difficult examples showed its good numeric...
