Electronic Toll Collection System using RFID and IOT

Project Cost: 9,400

Project Code: 5181

Description of the project:

With the significant development in Roadways, there is an increase in the number of toll plazas. These toll plazas have long queues and the time consumed in paying cash and returning change causes all the more delay. We have designed an Electronic Toll Collection System using RFID and IOT in which a person can use an RFID to pay the Toll charge. When the RFID is swiped, the system would check if it has sufficient balance and then deduct the toll charge and update the balance through IOT.

The Internet of Things (IoT) is basically the network of ‘things’ by which physical things can exchange data with the help of sensors, electronics, software, and connectivity. These systems do not require any human interaction. IoT Technology is found in many industries like healthcare, Energy, Transportation, etc. In this project, the data of the RFID card is sent to the website, through IOT.

A detailed description of Electronic Toll Collection System using RFID and IOT:

IOT Based Toll Booth manager system helps the toll booths to collect the toll by just swiping a card. The project consists of four keys by which the user can select the mode of toll collection. Once the RFID mode is selected, the LCD displays the message to show the RFID card. The card has to be then swiped on the Card Reader. After the card is swiped, the Arduino will check if the card is valid or not. If the card is valid then the micro-controller will check if the card has sufficient balance.

The card balance is displayed on the LCD display. Once the microcontroller detects sufficient balance, the toll gate is opened and the vehicle is allowed to pass through. We have used an IR-sensor i.e. Infrared Sensor to indicate that the vehicle has crossed the toll gate and the gate will be closed.

If the cardholder needs to recharge the card, the recharge mode is selected. The LCD displays that the Recharge mode is selected and instructs to show the card. The card has to be then swiped on the card reader. The LCD then shows the message to enter the recharge amount. The user has to enter the amount and then press Ok button.

Data sent over the cloud using IOT:

When a successful transaction has happened using an RFID, the following data is sent over IOT and the card details are updated.

• Toll booth Number
• RFID card number
• Balance in card
• Mode (RFID mode / Recharge mode)
• Date time stamp

In case an invalid RFID card is swiped OR any valid card with an insufficient balance is swiped, the micro-controller will detect it and the buzzer will be turned ON. If the commuter opts to pay the toll by cash, then the manual mode has to be selected. Once the manual mode is selected, the user needs to press the OK button and the toll gate will open.

The Prerequisite for this project is that the Wi-Fi module should be connected to a Wi-Fi zone or a hotspot. ESP8266, a highly integrated Wi-Fi solution is used for connecting micro-controllers to the Wi-Fi network and make TCP/IP connections. This project can also be implemented without the IOT module.

Technical Specifications:

The components that are used in the IOT based Toll booth Manager System project are:

1. RFID card reader – Used to read the unique RFID card number and send it to the Microcontroller
2. LCD – This will display informative messages like card balance, and if the card is valid or invalid
3. Microcontroller – Arduino reads the RFID card number from the RFID reader. It sends data to the LCD and performs operations based on the mode selected. Then it sends data to a motor if the card is valid OR to the Buzzer if the card is invalid or has insufficient balance.
4. Infrared Sensor- used to detect that vehicle has crossed the toll plaza
5. Transmitter: Infra-Red transmitters used are IR LEDs. IR rays from transmitters are reflected from the vehicle and are received by the receiver.
6. DC motor and Motor Driver: To open the gate and a motor driver IC is used to drive the motor.

Applications and Advantages of Electronic Toll Collection System using RFID and IOT:

1. IOT based Toll Booth Manager System can be used at all the Toll Plazas on the Highways.
2. Using this project would help the vehicles to pass the Toll Plaza without stopping which in turn would help people save a lot of their time.
3. This project can also be used at Octroi Collection booths

Future Development of the project:

1. The project can be extended to send an SMS to the cardholder whenever the card is swiped at any toll plaza along with balance details.
2. Voice System can be added to this project to indicate if the card is invalid or has insufficient balance

Question and answers about this project:

Question: How can the card user check the balance of the card?

Answer : According to the current implementation, the card balance can only be checked at the Toll Booths.

Question: If the recharge mode is not working for some reason at a toll Plaza, can the card still be used and maintain a negative balance?

Answer : Currently, we have not programmed the microcontroller for this. But this can definitely be done with some extra programming.
