LIGHT EMITTING DIODES FOR TRAFFIC SIGNAL DISPLAYS

This project examined the feasibility of using light emitting diodes (LEDs) for red traffic signals. The project involved a demonstration program of 27 LED signalized intersections in Philadelphia Pennsylvania. The project consisted of the following tasks: performance monitoring, laboratory performance, power consumption field measurements, driver observational study, and power calculation software development. At the conclusion of the project, results proved that red LED traffic signals provided superior performance and substantial energy cost savings when compared to standard incandescent signals.
