Electronic Toll Plaza using Wi-Fi

Automatic process of toll collection will save time, effort, and man power than the manual toll collection which is widespread in today's world. This project proposes a low cost and efficient technique called Electronic Toll Collection. Electronic toll collection requires several components in order to complete a transaction. The two most important components are vehicle recognition and account identification. This project uses RFID modules that automatically collects the toll from moving vehicles when they cross the toll plaza for recognition and account identification. If the balance in the owner’s account is low or if the vehicle is not equipped with an RF system, the toll gate remains close. In such a case vehicle owner will have to pay the toll tax in cash and collect the receipt. The owner receives an SMS message on his/she mobile about the details of the payment and there is no need for him to stop the vehicle. How many vehicles passing through the toll gate stored in a database. We can also find out a vehicle how many times passing through the toll gate in a day. This process of toll collection offers a minimum delay and increases the through put of the toll.
