说明：  设计一个交通信号灯类： （1）变量：位置、颜色（红、黄、绿）、显示时间（秒）。 （2）方法：切换信号灯。 创建并启动两个线程（东西向、南北向）同时运行。 3．实验要求 （1）设计线程。 （2）设计路口信号灯示意图界面。 （3）进一步将每个方向的信号灯分成3种车道灯：左转、直行和右转。 （4）根据车流量进行时间的模糊控制。(Design a traffic light class: (1) variables: location, color (red, yellow, green), display time (seconds). (2) Method: switch the signal lamp. Create and start two threads (east-west, north-south) running at the same time. 3. Experiment requirements (1) design thread. (2) Design schematic interface of intersection signal light. (3) Further, the signal lights in each direction are divided into three kinds of lane lights: left turn, straight ahead and right turn. (4) Fuzzy control of time according to traffic flow.)
