课程综合设计题目

4、模拟智能交通信号灯系统

    设计一个智能信号灯系统，在十字路口控制东西南北四个方向交通信号，当然是红灯停绿灯行了，一般情况是四个方向每次绿灯亮30秒，只不过在绿灯熄灭后亮3秒黄灯再转红灯。现要求系统能够根据各个方向路口来的车流情况动态分配信号灯在来车多的方向绿灯可以綖长30秒时间，为此在各个路口设有车流信号统计器，可以向系统动态发送车流信息。

 

 

看到题目我首先想到的是先写出红绿灯的程序先，因为红绿灯的变化是这个程序最基本的东西，

一开始我就写出了红绿灯秒数的变化，一开始是不会清屏，问同学就知道清屏是ststem("cls")

#include<iostream>
#include<windows.h>
using namespace std;

int main()
{while(1)
{int g;
	for(g=30;g>=0;g--)
	{
		cout<<" >>>>>>>> 绿灯<<<<<<<< 剩 "<<g<<" 秒"<<'\n';
	    Sleep (1000);
	    system ("cls");
	}
	int y=3;
	for(;y>=0;y--)
	{
		cout<<" >>>>>>>> 黄灯<<<<<<<< 剩 "<<y<<" 秒"<<'\n';
	    Sleep (1000);
	    system ("cls");
	}
	int r=33;
	for(;r>=0;r--)
	{
		cout<<" >>>>>>>> 红灯<<<<<<<< 剩 "<<r<<" 秒"<<'\n';
	    Sleep (1000);
	    system ("cls");
	}}
	
	

	
	
	return 0;


}

这个是一个方向的红绿灯计时的程序，运行出一个方向的红绿计时。

#include<iostream>  
#include<windows.h>
using namespace std;  
int main()  
{  
	int green=30,yellow=4,red[4]={1,34,67,100}; 
	int greena,greenb,greenc,greend;
	int yellowa,yellowb,yellowc,yellowd;
	int reda,redb,redc,redd;
	int i=0,j,k,l,a;
	while(1)
	{
		greena=30;
		greenb=30;greenc=greend=0;
		yellowa=yellowb=yellowc=yellowd=0;
		reda=red[0];
		redb=red[1];
		redc=red[2];
		redd=red[3];
		for(a=132;a>0;a--)
		{
		//	if(a%33==0&&a>=33)
			cout<<"\n------西路口-----\n";
			if(greena>0)
			{
				cout<<"   >>> 绿灯 <<< "<<greena<<" 秒\n";
				greena--;
				if(greena==0)
					yellowa=yellow;
			}

					yellowa--;
				}
				if(yellowa==0)
				{	
					
						i=3;
					reda=red[i];
				}
			}
			if(reda>0)
			{
				if(reda==red[i])
					reda--;
				else 
				{
					cout<<"   >>> 红灯 <<< "<<reda<<" 秒\n";
					reda--;
				}
				if(reda==0)
				{
					greena=green;
						i--;
				}
			}
                 /********************************************************************/

				{

					greenb--;
				
				}
				if(greenb==0)
					yellowb=4;
				
			}
			
			
			if(yellowb>0)
			{
				cout<<"   >>> 黄灯 <<< "<<yellowb<<" 秒\n";
				yellowb--;
				if(yellowa==0)
					redb=red[i+1];
			}
			
			/********************************************************************/

				greenc--;

			{
				cout<<"   >>> 黄灯 <<< "<<yellowc<<" 秒\n";
				yellowc--;
			}
			if(redc>0)
			{
				cout<<"   >>> 红灯 <<< "<<redc<<" 秒\n";
				redc--;
			}
			/********************************************************************/			
			cout<<"\n------北路口-----\n";

			}
			cout<<'\n';
			Sleep(100);

		}
		
	}
	
	return 0;  
}

暂时弄好了第一个方向的所有时间的计算，还有3个方向还没有弄好，其他方向的有时候不会显示出来时间，还有第二个方向红灯显示的时候连着黄灯会

一起跳动秒数。Sleep(100);是为了检验时间跳动的时候可以快一点。暂时做这么多，明天上实验课继续做。
