The Proposed System consists of developing a toll and speed detection system. The method used for speed detection and toll collection at most places is traditional. These traditional methods include manually collecting toll at the toll plazas and using laser guns to detect the speed of the vehicle. But manually collecting tolls can be very tedious and the speed detected by the laser guns is not always correct. Analyzing these traditional methods we have come up with a method – ‘RFID based Toll and Speed Detection’. In this method, RFID tags will be given to all the cars according to their classes and will also contain basic information about the car owner and information about the prepaid balance. RFID Reader will be placed at the toll plaza. Speed detection system will be used on highways. Here the RFID Reader will be placed on the highway and calculate the speed of the vehicle. If the vehicle is overspeeding, fine will be deducted directly from the balance. A real-time database will be created using Python which will keep informed of the car owner, their prepaid balance and also their updated balance. This RFID system at the toll plaza will avoid long queues and also save fuel which in turn is beneficial for the environment. On the highways, RFID system will help in avoiding accidents due to overspeeding vehicles.
