软件：Quartus

语言：VHDL

代码功能：

交通灯控制器

设计一个交通灯控制器，由一条主干道和一条支干道汇合成十字路口，在每个入口处设置红、绿、黄三色信号灯，红灯亮禁止通行，绿灯亮允许通行，黄灯亮则给行驶中的车辆有时间停在禁行线外。

1、红、绿、黄发光二极管作信号灯，用传感器或逻辑开关作检测车辆是否到来的信号；

2、主干道处于常允许通行的状态，支干道有车来时才允许通行。主干道亮绿灯时，支干道亮红灯；支干道亮绿灯时，主干道亮红灯；

3、主、支干道均有车时，两者交替允许通行，主干道每次放行45秒，支干道每次放行25秒，设立45秒、25秒计时、显示电路；

4、在每次由绿灯亮到红灯亮的转换过程中，要亮5秒黄灯作为过渡，使行驶中的车辆有时间停到禁行线外，设立5秒计时、显示电路。
