Detection of Traffic Signal Violation Using Ultrasonic Sensors

Traffic Signal violation is a day to day occurrence in todays world. Though the traffic police are able to book a few trespassers they are not able to completely stop each and every violation. In this paper we introduce the concept of ultrasonic sensors which helps to identify the violator and at the same time do an image capture of the vehicle number plate from the ANPR CCTV cameras (automatic number plate recognition camera). This helps to identify the vehicle and give information to the traffic police even after the vehicle has fled the scene. At the same time, traffic jam and accidents can be avoided. Signal jumping drivers can also be booked and fine amount sent to the residential address of the violator. This is implemented by placing two ultrasonic sensors on each side of the traffic signal path. When vehicle jumps the signal, the ultrasonic sensor detects the object and triggers the camera. It helps to capture the vehicle number plate at the right time and identify the owner of the vehicle from the registration database available. The information of violator can be tracked immediately with the help of GUI.
