交通高峰期路段交通流动力学模型

摘要

The dynamical laws of traffic flow in rush hours are studied. In order to solve the problem of traffic jam,the traffic rules in rush hours are explored in this paper based on the conservation law of vehicle number. The traffic flow parameters are analyzed. The differential equations of motion of traffic flow are established. One-dimensional dynamical model of traffic flow of road section is obtained through theoretical derivation. The results of simulation show that the model can reflect the basic characteristics of traffic flow and provide theoretical basis for the department of transportation to regulate traffic flow in rush hours.%研究了交通高峰期交通流的动力学规律。为了解决交通高峰期交通堵塞的问题，从车辆数量守恒的思想出发，对交通高峰期的路段交通流规律进行了探讨，分析了交通流参数，建立了交通流运动微分方程，通过理论推导得出了路段的一维交通流动力学模型。通过仿真实验表明，此模型能反映交通流的基本特性，能够为交通部门在交通高峰期调节路网交通流提供理论依据。
