Automated Toll Collection System

Automated Toll Collection System

Automated toll based collection system has helped a lot in reducing heavy congestion which has caused in front of the bridges of busy cities of the world. It is also the easiest method to control heavy flow of traffic. Digitally it captures the radio frequency by means of RFID technology. In this method a RF tag along with a unique code will be attached to the vehicle which emits RF signals. Every owner has to have an account with RFID tag attached to their vehicle. Whenever the vehicle reaches nearer to the entrance toll gate the signals will be detected and passed to the controlling device. If the vehicle owners are found with sufficient amount of balance in their account, only then they will be allowed to pass [4]. Again digital toll based collection system has also been found in developed countries like Canada which is known as Canada 407 Express toll route (ETR). In this system they introduced optical camera with Optical Character Recognition (OCR) which captures images and recognizes license plates without any tag.

In Gujrat, a state of India there is electronic toll collection system using radio frequency and tag operates commercially on expressway where all needed equipment were supplied by Mitsubishi Heavy Industries [6]. Again India has got its first interoperable RFID based electronic toll system in Ahmadabad- Mumbai National Highway which enables automobiles having electronic tags operates at frequency of (850-950 MHz) with distance up to 90 feet where response time is 10 milliseconds [6]. This system can be considered as cost efficient but the driver has to get the receipt and pass through the gate.

Furthermore, an institution named Active wave Inc. has come up with a system which monitors active tagged vehicles [7]. These automobiles have active wave ranging 30 meters operating (916-917 MHz) for operation transmit and (433MHz) for receiving the link. Here, in form of blinking LEDS and beeping sounds the signals are observed. Moreover, the user interface has been designed using Microsoft .NET Framework.

The tag uses car battery for power and two modules through RF modem transfer signals among themselves over the ISM frequency range of about (902-928) MHz. Another proposed model of digital toll collection has been developed in Poland which has got a combination of GSM and satellite based global positioning system [4]. Here the system has got sensors and camera which captures and detects number plate. In addition, it captures the distance, evaluates the fees and rates transmitting them to the System Centre.

In our proposed model, we have built a suitable computerized Toll Collection System. The RFID implanted car number plate is allocated to the system. Our prototyped Digital Toll Plaza is made up with Arduino Mega, RFID reader, Display and servo motor for the Toll gate. We have used Arduino IDE programming language to run the system of our Toll plaza. CodeShoppy.com
