分时段协调控制的交通信号灯控制系统的设计

The Design of a Traffic Light Control System Based on Time-sharing Coordinating Control

当今大部分城市的交通信号灯控制系统都采用单调的定时控制。这样的控制方式对于如今瞬息万变的交通车流量情况无法很好的适应。干线协调控制策略近些年来得到飞快发展,使得交通信号灯控制系统的优化工作也有了重要的依托,但是实践也证明这样的控制策略并不能完全符合要求,因此在本文中提出了分时段协调控制的策略并大致介绍了这样的控制系统具体实现方面的结构问题。

Currently, fixed-time control is applied to the control system of traffic light in most cities, but it fails to adapt to constant changes of traffic flow. To solve the problem, a main line coordinating control strategy is developed and applied as an important basis for the optimization of the traffic light control system. However, even such a control strategy has also been proved to be unable to meet the requirement. Therefore, another timesharing coordinating control strategy is proposed in the paper together with an introduction to structural problems which may occur in its actualization.
