然后，他们给每个交通信号灯装上传感器，用以了解特定时段的路面信息。
Then they gave each traffic signal a sensor that provides information about traffic at a given moment.
本文介绍了一种基于电子工作台(ewb)软件设计交通信号灯自动定时控制系统的方法，说明了计算机仿真软件在电子实验中的效用。它改变了传统的设计方法。
The paper presents a method of simulation on auto-timing system of traffic lights based on EWB, which has changed the traditional design method, and illustrates the method of design and simulation.
但现有的交通信号灯控制系统都是单一的固定时序控制，不能够根据实际交通状况进行调节控制。
But all the traffic light control systems are working in standing sequence, and are unable to make adjustment with different traffic flow.
