__Traffic congestion significantly impacts the transportation system in the country, particularly during emergencies at busy intersections.To address this issue, a congestion control system has been developed.This system activites when it detects a sign from an ambulance using radio freqency transmission and employs a microcontroller to revert to the normal traffic sequence after the emergency mode is initiated.By allowing other vehicles to clear the way for emergency responders, this system aims to alleviate the common problems faced at traffic light junctions.The project successfully implements wireless communication via RF trasmission within the traffic light control system for ambulances.Its primary goal is to automatically manage traffic signals in response to emergency situations.Future enhancements could focus on effectively managing real traffic congestion,thereby advancing existing traffic light technology.The current traffic control systems often have limitations due to their reliance on fixted timing methods.
