交通灯模拟管理系统 模拟实现十字路口的交通灯管理系统逻辑，具体需求如下：



? 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

。。。



? 信号灯忽略黄灯，只考虑红灯和绿灯。



? 应考虑左转车辆控制信号灯，右转车辆不受信号灯控制。



? 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。



? 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）。

-Simulation to achieve the traffic light intersection management system logic, the specific requirements are as follows: ? Asynchronous randomly generated according to various routes of the vehicles. For example: to go from south to north from the vehicle---- straight to the traffic from south to west to come to the right of vehicles---- Vehicles coming from the east to the south to the vehicle---- left turn vehicles. . . ? ignoring yellow lights, consider only the red and green. ? should consider vehicle control lights turn left, turn right at traffic lights are not controlled. ? ? randomly generated vehicle traffic light switching interval and the time interval from the set, you can set.
