Automated Toll Collection System

Abstract

Due to the expansion of the vehicle transportation system, Jam on toll collection booth is common nowadays & become a serious problem in recent years. Because of increase lots of vehicle and toll are collected by human, lots of time waste is occurring here, so it is essential to design & implement a modern system, which can monitor & collect toll from these vehicles automatically. A system that is able to sense the vehicle and collect toll from the vehicle automatically. So, human toll collector is not needed here and vehicle don’t need to waste time by waiting on toll booth because it will collect toll faster than human toll collector. In our project, we have showed it by interfacing stepper motor, sonar sensor and Arduino Uno microcontroller. When a vehicle arrives, if the car owner has registered RFID card and sufficient balance on his RFID card, he just need to punch it on RFID sensor, the other work will be done by our system automatically like deduct actual toll amount from RFID balance. Also, there will be two sonar sensor to sense the arriving and leaving of the car. So, it will bring automation on barrier which have made by stepper motor. When a car arrives to the toll booth, the first sonar sensor will sense that, car have arrived and sensor will wait for the car to punch RFID card on RFID sensor and start counting the time and if the car owner don’t punch RFID card on RFID sensor because of haven’t any registered RFID card or haven’t sufficient amount of balance on RFID card or any other reason, system have Buzzer that will make a loud sound of alarm to make the car owner alert to punch RFID card or go left for pay manually and a message will show on LCD display named Please Go Left and left sign for the better understand of the car owner, Then it have to go for manual pay and pay the amount of toll with some amount of fine. But, if the car owner has registered RFID card and sufficient amount of balance and punch on RFID sensor, the barrier will rise up by 90 degrees and wait for the car to go and the second sonar sensor will sense the leaving of the car and when it passes away the motor barrier will go down by 90 degrees. Actually, the rise and down of stepper motor barrier will also be automated. So, any human operator isn’t needed here to operate the stepper motor barrier as well as all the system will be automated and reduce time waste on toll booth
