摘要： 在对干道车流运行特性进行深入研究的基础上，采用差分近似代替微分的方式对传统的交通流流体动力学理论进行了改进;并且用准冲击波分析方法对干道行程时间和干道行程车速进行了模拟和预测研究，以满足快速预浏的要求，为城市干道交通流的科学管理和控制提供了一种分析工具.

Abstract: This paper improves the traditional Traffic Flow Hydrodynamic Theory by means of alternating the difference by differential, on the basis of the research on the characteristic of the arterial traffic. And also the quasi shock waves analysis methods developed in this paper are applied
to simulate and forecast the arterial travel time and travel speed. In this way, a tool for the urban arterial road management and control is raised.

Key words: characteristic of traffic, quasi shock waves, Hydrodynamic Theory, arterial travel time
