应用于交通流中的欧拉微分方程

Euler Differential Equation Applied to the Traffic Flow

交通流的流量、速度、密度是表征交通流特性的三个基本参数,它们在交通流理论的不同模型中有着不同的描述。本文对有粘性助力项的交通流的欧拉方程进行了动态研究,并对三个参数之间的相对变化率进行了分析。

The flow,speed and density of the traffic flow are three basic parameters to characterize the traffic flow characteristics,and they have a different description to the different models of traffic flow theory.This paper studied the Euler equations of traffic flow with viscous help key,and analyzed the relative rate of change among the three parameters.
