LITERATURE REVIEW

Jose E.Ortiz, Robert H.Klenke, Simple Traffic Light Controller: A Digital Systems Design Project.Electrical And Computer Engineering Department Virginia Commonwealth University

• This project required students to develop a state machine based controller for traffic signals at a four-way intersection. The intersection has two travel lanes in each direction; north, south, east and west. In addition, each direction has a dedicated left turn lane. Each lane contains a sensor to indicate if a car waiting at a red light. Travel lanes also contain additional sensors to indicate if cars are approaching the intersection.

• This project design of a low cost performance traffic light system. This type of traffic light is suitable for town and small city where sophisticated traffic light system is too costly. Written in verilog on Quartus II software and implemented on DE2 FPGA Board.
