Consider the following variation on the traffic light controller problem. A North-South road intersects

an East-West road. In addition to the Red/Yellow/Green traffic lights, the N-S road has green left-turn arrows. The arrows work as follows. With the traffic lights red in all direction, the N-S left turn arrows are illuminated Green. Then they turn yellow and finally they turn red. At this point, the N-S lights cycle Green/Yellow/Red. In the N-S direction, the Green Arrow time is 16 seconds and the Yellow Arrow time is 8 s. Overlapping with this is Red light time, which is 88 s. The Green light time is 24 s and the Yellow light time is 8 s. The Red Arrow time is what is left after the other arrows have been illuminated within the N-S cycle. The E-W lights are: Red 56 s, Green 56 s, and Yellow 8 s. -Consider the following variation on the traffic light controller problem. A North-South road intersects
