简介： 交通信号灯十字路口通行原理图。
前言
交通信号灯十字路口通行原理图。
实际上归类为四大类：
南北双向直行 东西双向直行 一对黑色粗线的左转 一对红色粗线的左转。
状态逻辑图如下图所示：
一、运行效果
点击开始：进入120s的整个循环中，第一部分南北直行绿灯在25s后变为黄灯持续5s，然后为红灯；第二部分南北左转灯对应变为绿灯并进行倒计时，然后黄灯，红灯；第三部分就是东西直行的绿灯黄灯红灯，第四部分是东西左转的绿黄红切换。
南北向、东西向行人在对应的时间切换绿灯和红灯。 停止按钮，停止计数器的计时。 思路：1秒的定时器计算时间，到了对应的时间阶段，触发界面的状态变化和倒计时。详情见代码。二、界面设计
控件和命名图片中标出了同系列的第一个，其余的根据方向类推命名。
三、代码：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using System.Threading; namespace TrafficLight { public partial class Form1 : Form { public Form1() { InitializeComponent(); } int time = 0;//计时器 const int MAX_LOOP_TIME = 120;//120s时间为一次循环 //以下时间段分别为：南北直行绿灯25，南北直行黄灯5,南北左转绿灯25,南北左转黄灯5,东西直行绿灯25,东西直行黄灯5,东西左转绿灯25,东西左转黄灯5 int[] PassTime={25, 30, 55, 60, 85, 90, 115, 120}; //事件委托的方式触发 public delegate void delegateTrafficLight(int tm); public event delegateTrafficLight EventTrafficLight; private void btnStart_Click(object sender, EventArgs e) { timer1.Start(); //Thread threadLightChg = new Thread(LightChange); //threadLightChg.Start(); } private void btnStop_Click(object sender, EventArgs e) { timer1.Stop(); } private void timer1_Tick(object sender, EventArgs e) { //计时开始，进入循环,120s为一次循环 if (time < MAX_LOOP_TIME - 1) //119秒后置为0秒 { time += 1;
