该控制器在设计上控制了一个繁忙的高速公路（高速路的红绿灯）

相交一岔路（SRD）等具有相对较轻的交通负荷。图1显示

在交通灯的位置。在十字路口传感器检测汽车的存在

在公路上和岔路。该图意味着，无论是公路和副作用

道路提供每个方向的交通单一车道。这两个普通的道路（红，

黄，绿）信号灯。交集装有一个传感器。-The controller to be designed controls the traffic lights of a busy highway (HWY) intersecting a side road (SRD) that has relatively lighter traffic load. Figure 1 shows the location of the traffic lights. Sensors at the intersection detect the presence of cars on the highway and side road. The Figure implies that both the highway and side roads offer single lanes for traffic in each direction. Both roads have ordinary (Red, Yellow, Green) signal lights. The intersection is fitted with a sensor.
