AUTOMATIC TRAFFIC LIGHT FOR AMBULANCE USING PERIPHERAL INTERFACE CONTROLLER

Traffic lights play such important role in traffic management to control traffic on the road. Situation at traffic light area is getting worse especially the event of emergency cases. During traffic congestion, it is difficult emergency vehicle to cross the road which involves many junctions. Situation leads to unsafe conditions which may cause accident. An Automatic Traffic Light Controller for Emergency Vehicle is designed and developed help emergency vehicle crossing the road at traffic light junction d emergency situation. This project used Peripheral Interface Controller to program a priority-based traffic light controller for emergency vet During emergency cases, emergency vehicle like ambulance can traffic light signal to change from red to green in order to make clear its path automatically. Using Radio Frequency (RF) the traffic light opera will turn back to normal when the ambulance finishes crossing the road. Showed the design is capable to response within the range of 55 meter project was successfully designed, implemented and tested.
