模拟实现十字路口的交通灯管理系统逻辑，具体需求如下：



1、异步随机生成按照各个路线行驶的车辆。 例如：



由南向而来去往北向的车辆---- 直行车辆

由西向而来去往南向的车辆---- 右转车辆

由东向而来去往南向的车辆---- 左转车辆



。。。



2、 信号灯忽略黄灯，只考虑红灯和绿灯。



·3、应考虑左转车辆控制信号灯，右转车辆不受信号灯控制。



·4、具体信号灯控制逻辑与现实生活中普通交通灯控制逻辑相同，不考虑特殊情况下的控制逻辑。



注：南北向车辆与东西向车辆交替放行，同方向等待车辆应先放行直行车辆而后放行左转车辆。



·5、每辆车通过路口时间为1秒（提示：可通过线程Sleep的方式模拟）。



·6、随机生成车辆时间间隔以及红绿灯交换时间间隔自定，可以设置。



·7、不要求实现GUI，只考虑系统逻辑实现，可通过Log方式展现程序运行结果。-Simulation realize intersection traffic management system logic, specific requirements as follows:



1, asynchronous randomly generated according to each route traffic. For example:



From south to north and the vehicle- straight vehicles

And by the west to the southbound vehicles- turn right vehicles

From the east to and to the southbound vehicles-- to turn vehicles



...



2, semaphore yellow lights, considering only ignoring red lights and green.



· 3, should consider left vehicle control lights, turn right vehicle not controlled by the traffic.



· 4, specific light control logic and real life ordinary traffic control logic is same, not consider special situations of control logic.



Note: north-south and east-west vehicles, vehicle alternate release in waiting vehicles should first clears go straight vehicles and then release left vehicles.



· 5, every car through the intersection time for 1 second (hint: can Sleep through threads of simulated) way.



· 6, randomly ge
