A three way intersection is in need of a traffic signal control system and you have been assigned the
task to design and implement the system. Each direction has only one lane and one set of signal
control lights (green, yellow and red). Your design should only allow one go or green light at a
time. Further, all transitions from green to red should go through an intermediate 2-4 seconds
yellow light. Complete the following steps for this design:
1) Sketch of the intersection with variables identified and respective values defined. Clearly
describe any additional assumptions or rules you have added.
2) Document design with tools such as characteristic table, truth table, k-map, state diagram,
physical layout, schematic and other as appropriate.
3) Implement the intersection control signal using LED’s to represent the lights and switches
to represent arrival and departure of cars.
4) Demonstrate your final implementation to the lab instructor based on your test plan which
you have already used to validate the design implementation.
