用微分方程方法研究红绿灯控制下的交通流模型

红绿灯模型是交通流动力学模型研究中一个重要而困难的问题，首先给出交通流模型，然后给出红绿灯交通流模型与特征线的求解，根据红绿灯模型与特征线意义，对交通流的红绿灯转换周期的设置具有重要意义．

Using differential equation methods to study traffic flow models under the control of traffic lights

Traffic light model is an important and difficult problem in the research of the traffic flow dynamic model. This paper, firstly shows the traffic light models, then explains the solution to traffic lights models and various characteristics. Based on the meaning of traffic light models and various characteristic lines, the establishment of transferring cycle of traffic light in the traffic circulation is of great significance.
