Traffic problems nowadays are increasing because of the growing number of vehicles and the limited resources provided by current infrastructure. Also, road accidents are the major cause of deaths in India. This is some serious matter at hands and measures need to be taken to save the lives of the victim, by providing proper medical aid on time. We propose a system for controlling the traffic light by image processing and an accident detection and rescue process. This system will detect vehicles through images captured by a camera installed alongside the traffic light. These images are processed using Image processing techniques to obtain the density of vehicles in each lane and also detects the presence of an ambulance, this data is sent to the microcontroller. Based on this data, the microcontroller sets the LED's such that the lane with more density is allowed to the pass the traffic signal. If an ambulance is detected in any lane, then priority is given to that particular lane. Also, the spot is continuously monitored for accidents. If any accident occurs, the microcontroller detects this using the vibration sensor. Immediately the microcontroller sends a message containing the location of that spot, to the nearest health care center, thus initiating an immediate rescue process.
