With the continued development and economicgrowth, Bangladesh needs to be digitalized in every way possible. In this paper, RFID based Automated Toll Collection System is introduced as a solution of the traffic problems and also to maintain transparency in the toll collection system. The proposed system aims to make a digital toll collection system which can eliminate the delay on toll roads, toll bridges and toll tunnel without cash and without requiring cars to stop. This paper focuses on an electronic toll collection system which uses radio frequency identification (RFID) technology to identify a vehicle specifically for collecting toll.
The proposed RFID system uses tags that are mounted on the digital number plate of the vehicles, through which information embedded on the tags are read by RFID readers. It is possible to reduce the need for vehicle owners and toll collection authorities to distribute tickets and collect tolls manually in this system Information on the toll payment can also be easily exchanged between the vehicle owners and toll authorities. As a result, transparency in toll payment can be ensured with reduced manual labor and human errors. Thus, building smart transportation system will become easier.
In this century, people live a life which is solely dependent on technology. New innovations are made to make out life less demanding, calm and more agreeable. The primary goal of advancement has been to extend capability and diminishing effort. In the present scenario, the world is straightly moving towards automation. Automation is the use of various management systems for running instruments such as- machinery processes in factories, boilers, and heat treating ovens, change on telephone networks, steering and stabilization of ships, craft and different applications and vehicles with possibly reduced human interventions and better accuracy . Highways or Toll Roads are provided to enhance the traffic, improve the distribution of goods and services, and increase mobility and accessibility of people. The problem starts when there is long queue. This queue occurs because the arriving rate of vehicles to toll gates is much higher than the servicing rate . This congestion will lead to wasting time for wait, incendiary fuel combustion, and air pollution caused by vehicle exhaust . Utilization of automated toll collection gate will help to improve the toll service by saving time, saving fuel & reducing gas emission. Code Shoppy In the proposed system RFID reader will read the RFID tags that are mounted on vehicles and the system will automatically deduct a specific amount of toll from the scanned tag id with the help of the database. As there is no need for vehicles to stop or toll authorities to manually collect the tolls, this system eliminates the traffic jam and possible human errors that normally happen in a toll collecting system making it a more efficient process.
Arduino Mega R3 2560: Arduino Mega R3 2560 is the microcontroller used for the project. The Arduino Mega R3 2560 is a board based on the ATmega2560 microcontroller. It is the most important component of our system all processing takes place in these block . Different microprocessors and controllers are component of various models of Arduino. The board supplied has many pins that can be used to interact with various appliances and boards.
RFID Reader:A RFID reader is a tool used to gather data from an RFID tag to track individual items. This low-cost MFRC522-based RFID reader module is simple to use and can be used in a variety of applications.Performance of an RFID system depends on several factors such as the orientation of tag, the material of the item to which a tag is attached, and the environment in which the system operates .RFID tags contain a distinctive code that distinguishes the vehicle class that passes through the tariff port.The RFID tag is inserted in the vehicle.Every vehicle has a distinctive identity that can be readily identified by the RFID reader. On the other hand, the RFID reader reads all RFID tags to get their unique ID numbers, and the Arduino is programmed to recognize only some RFID tags, enabling only registered tag cars
Servo Motor: A servomotor is a rotary actuator or linear actuator enabling accurate angular or linear position, acceleration speed and control. It is an appropriate position feedback engine in combination with a sensor.Motor driver is an IC which is used to drive the motor .We also use it to pull up and down the toll square’s passing door. It is an engine with 3-pin energy, cable control and hardware mounting. It is rotating at 180 degrees.
LCD Display (16*2): An LCD is an electronic screen module that uses liquid crystal to create a visible picture. This 16×2 LCD display is a very fundamental module that is very frequently used in various systems and circuits.The job of LCD will be to display all the system generated messages coming from the controller . These modules in various sections are preferred over 7 sections and other LEDs. There are two registries in this LCD, Command and Data. The LCD command register primarily stores the instructions provided to the LCD while the information register allows the information to be displayed on the LCD.
