Description: 中南大学单片机交通灯课程设计，程序实现功能：
1.在一个十字路口的一条主干道和一条支干道上分别装上一套红、黄、绿3种信号灯，
用钮子开关模拟十字路口的车辆检测传感器信号。在一般情况下，主干道上的绿灯常亮，而支干道总是红灯。
2.当检测到支干道上来车时（用按键开关模拟），主干道的绿灯转为黄灯，持续4S后，又变为红灯，同时支干道由红灯变为绿灯。
3.支干道绿灯亮后，或者检测到主干道上来了3辆（用3个钮子开关模拟），或者虽未来3辆车，
但绿灯已经持续了25s，则支干道立即变为黄灯，4s后转为红灯，同时主干道由红灯变为绿灯。
4.当有紧急情况时，如有120救护车，119救火时等情况，所有车让路，主干道支干道变红灯。-Central South University microcontroller traffic lights curriculum design, program functions: a crossroads of a main road and a branch roads were fitted with a set of red, yellow, green, three kinds of signal lights, toggle switch analog crossroads vehicle detection sensor signal.

Description: Traffic light problems in verilog code.
Consider a controller for traffic at the intersection of a main highway and a country road
The traffic signal for the main highway gets highest priority because cars are continuously present on the main highway. Thus, the main highway signal remains green by default.
Occasionally, cars from the country road arrive at the traffic light signal. The traffic signal for the country road must turn green only long enough to let the cars on the country road go.
As soon as there are no cars on the country road, the country road traffic signal turns yellow and then red and the traffic signal on the main highway turns green again.
There is a sensor to detect cars waiting on the country road. The sensor sends a signal X as input to the controller. X=1 if there are cars on the country road otherwise, X=0.
There are delays on transitions of states (Delay of Red & Green lights is longer than Yellow light).-Traffic light problems in verilog code.
