BACKGROUND INFORMATION FOR THE QUESTIONS:
Known facts:
•
East-West (EW) road has heavy traffic and needs to flow as well as
possible
•
North-South (NS) road has less traffic
•
NS road has car sensors to indicate when there is a vehicle waiting
•
SensorN for north
•
SensorS for south
•
Pedestrians have request buttons to indicate they wish to cross
•
The request buttons are one per road
•
RequestNS to cross NS road
•
RequestEW to cross EW road
• The lights are always on and operating
•
The lights are only based on demand, there is no schedule
Goals:
•
Safe flow of people and vehicles
•
Maximum throughput
•
Minimum cost to create
