Smart traffic signal using ultrasonic sensor

Traditional traffic signal system only gives instructions to stop and not to vehicle driver. But if someone is breaking the signal then this system is not able to catch them and there are chances of taking bribe. Therefore to increase the security of traffic signal and to reduce human efforts and to avoid the bribery we are introducing smart traffic signal system through this research paper. Smart traffic signal based on the microcontroller & ultrasonic sensor, in which ultrasonic sensors are placed at one side of road in such a way so as to cover particular necessary area of road from where the vehicles are restricted to pass. If the signal is red and any vehicle is breaks the signal then ultrasonic sensor detect it and microcontroller take immediately action to buzzer alarm along with camera capture the image of that vehicle. It also make record of when, where, which vehicle breaking signal by saving image in particular folder as name of current date and time.
