信号灯控制下的交通流模型

Traffic Flow Model under the Control of Traffic Lamp

摘要: 首先引入交通流基本函数,推导出流量、密度、速度3者之间的关系,在此基础上对交通流连续运动建立方程,并引入特征线,从几何意义上分析求解结果。发现对于沿车流方向前面车流密度小、后面密度大的情形完全适合,但对于相反情形却不适用,从而引出了间断交通流方程。最后利用这两方程讨论了红绿灯相继出现时交通流的变化全过程。

Abstract: When traffic lamp is changed, traffic volume and density will vary. On the basis of traffic volume-density equation, the functions of continuous and separate traffic volume are presented. The traffic flow under the control of traffic lamp is discussed by using these functions.
