You are implementing a control system that is responding based on a situation and input. The parts of the situation are broken down as follows. $$ Two roads intersect perpendicularly. $$ One road is a highway road. $$ One road is a country road. $$ There is a traffic signal for each road. $$ Traffic only runs in one direction on each road. $$ There are no delays from external factors in this system, so it doesn$$t matter if the sun is visible. $$ There is a bridge further down the highway. $$ Each signal can be green or red. $($Yeah in reality there is yellow, but that makes this problem harder$)$ Both signals can not be green at the same time, but there are times when both should be red. $$ Cars and trucks use these roads. So do motorcycles. $$ It doesn$$t matter how many people are in the vehicle. $$ A vehicle is anything with wheels. $$ There is an overall enable that corresponds to the sensor counting the vehicles being on or off; if the sensor is off, then the country road will have a red light. $$ The vehicle counting sensor will always be functioning unless the system is not enabled. $$ If you follow the country road you will find a pumpkin farm. $$ There is a weather sensor that tells if it is snowing or not. $$ There are three vehicles parked on the side of the road $$ There is a counting sensor that tells how many vehicles pass through the intersection. $$ All vehicles are treated equally independent of how many wheels it has. $$ The counting sensor$,$ weather sensor$,$ and the sensor enable must be used as a factor to decide which color each signal is$.$ Each time you have to change the signal color, you must temporarily have both signals red to avoid collisions. $$ During the transition time for the signal, there will be no vehicles going through the light, so the counting sensor can be ignored. $($You can assume ideal behaviors of the drivers$)$ The area has lots of wild turkeys roaming around and the occasional goose. $$ Vehicles move at a constant speed. $$ All vehicles are controlled by humans
