Automatic toll tax project is designed, using Philips P89V51RD2 microcontroller & discrete components. Both RFID and GSM Module are required in this project. RFID Module is used for tracking the details of vehicle and the GSM Module to keep the record of Payment of Toll Tax. I have designed this project as a simple implementation of the toll collection process automatically in a model form. This should not be considered as a real toll collection system which requires much more considerations, tests and huge amount of money, before they are actually put into use.

The source code for this project is written in assembly language using the software RIDE.

A TOLL TAX is basically TAX collected on toll road (also toll way, turnpike, toll highway, or express toll route) is a privately or publicly built road.GSM(Global system for mobile communication originally Groupe Spécial Mobile) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe protocols for second generation (2G) digital cellular networks used by phones. It became the global standard for mobile communications.GSM was designed with a moderate level of service security. The development introduced an optional  Subscriber Identity Module (SIM) that uses a longer authentication key to give greater security. RADIO FREQUENCY IDENTIFICATION (RFID) is a frequency based system that provides the details of the vehicle i.e. vehicle number and type of vehicle (if reqd.)TOLL TAX COLLECTION SYSTEM USING RFID & GSM” employs a SIM 300 GSM module and a 121/110/132RFID module. These devices are interfaced to the P89V51RD2 microcontroller to enable serial communication. We have not changed the existing procedure at toll tax collection booth we have advanced it to a certain level for fluency in flow of traffic.

Fig 1: General view of toll booth using GSM & RFID

Fig 1 shows how the RFID and GSM  works for toll tax collection by reducing manual work. A simple IR sensor is placed to sense the arrival of vehicle by which an alarm is raised inside the toll booth. As the vehicle comes in the range and receives the transmitted signal transmitted from toll booth. Due to this a transreciever circuit is generated and with the help of GSM module installed in vehicle sends the data i.e. vehicle number and available balance. As this action takes place the required amount is deducted from the main balance of the user’s GSM module and vehicle is passed. If there is no sufficient balance or vehicle does not have the advanced facilities the existing procedure is followed and vehicle is passed.


Conducting literature survey prior to begin a research project is vital in understanding a automatic toll collection system, as this will supply the researcher with much needed additional information on the methodologies and technologies available and used by other research counterparts around the world.

1. Automatic Toll Gate System Using Advanced RFID and GSM Technology [3]

According to S.Nandhini, P.Premkumar, most Electronic Toll Collection (ETC) systems around the world are implemented by DSRC (Dedicated Short Range Communication) technology. The concept proposed is of automatic toll tax payment system and the amount transaction information sends to the cell phone of the motorists through the GSM modem technology. It is an innovative technology for expressway network automatic toll collection solution. In this paper, the frame composing and working flow of the system is described and data information is also easily exchanged between the motorists and toll authorities, thereby enabling a more efficient toll collection by reducing traffic and eliminating possible human errors.

2. Automatic toll collection system using RFID [1] According to Aniruddha Kumawat and Kshithija

Chandramore ATCSR is an Automated Toll Collection System using RFID used for collecting tax automatically. In this we do the identification with the help of radio frequency. A vehicle will hold an RFID tag. This tag is nothing but unique identification number assigned. This will be assigned by RTO or traffic governing authority. In accordance with this number we will store, all basic information as well as the amount he has paid in advance for the TOLL Collection. Reader will be strategically placed at toll collection center Whenever the vehicle passes the toll booth, the tax amount will be deducted from his prepaid balance. New balance will be updated. Incase if one has insufficient balance, his updated balance will be negative one. To tackle this problem, we have camera on the way to capture the image of respective vehicle. As vehicles don’t have to stop in a queue, this translates to reduce. Traffic congestion at toll plazas and helps in lower fuel consumption. This is very important advantage of this system

3. Electronic toll collection system using passive   RFIDtechnology [2]

According to Khadijah Kamarulazizi and Widad Ismail,this paper focuses on an electronic toll collection (ETC)system using radio frequency identification (RFID)technology. Research on ETC has been around since 1992,during which RFID tags began to be widely used in vehicles to automate toll processes [1]. The proposedRFID system uses tags that are mounted on the windshields of vehicles, through which information embedded on the tags are read by RFID readers; The proposed system eliminates the need for motorists and toll authorities to manually perform ticket payments and toll fee collections, respectively. Data information are also easily exchanged between the motorists and toll authorities, thereby enabling a more efficient toll collection by reducing traffic and eliminating possible human errors. With reference to Journal of Theoretical and Applied Information Technology.


The basic block diagram of the Automatic Toll Tax Collection system (for both Transmitter and Receiver section) using RFID& GSM is shown in the below figure 2. The various blocks are listed and briefly discussed below.

 1. Transmitter section

Fig 4: Circuit diagram of transmitter section

The microcontroller is interfaced with motor, IR sensor, L293D (motor driven IC), MAX232, HT12E, RF transmitter. The RF transmitter is connected with HT12E for the encoding of signal received from the receiver circuit. The motor is connected with IC L293D, as this IC is necessary for driving a motor as it’s a current amplification IC.The communication port DB9cable is used for serial communication with the microcontroller by MAX232. Now when the circuit is ON the RF transmitter is always ON. The IR sensor near the booth detects the arrival of the vehicle and alerts the operator.

The gate of our circuit is always kept open. The gate is driven by a gearless motor with interfacing of L293D IC. The HT12E which is connected with RF transmitter encodes the data received from the receiver circuit. In this way the Transmitter circuitry operates.

 2. Receiver section

Fig 5: Circuit diagram of receiver section

The circuit consists of the components listed above and the microcontroller has the main role of action. The microcontroller is interfaced with MAX232, HT12D and RF receiver. When the receiver circuit is on supply is provided but   controller only works on 5v.This is done by LM7805 Ic.This IC gives 5v to the entire circuit. Now RF receiver will receive the data from RF transmitter and this data will applied to HT12D which is the decoding.

With the help of this IC complete data which is encoded from transmitter get decoded and then decoded data is applied to controller.IC MAX232 is another component interfaced with controller which provides stability between two stages.Then complete program is feed into controller through or help of this IC using RS232 which is connected to pc.Then  once the programing is completed in controller complete information i.e balance amount is displaced on LCD at receiver.


By practically implementing ‘Automatic Toll Gate System using RFID& GSM Technology’ we can provide a convenient transportation for the public i.e. we can avoid traffic congestion. It is the most efficient way of toll collection which can reduce the manual effort at toll plaza. We are avoiding the emergency vehicles such as ambulance, fire force etc. from the toll collection. In this busy world we give preference for time and efficiency, so for fulfilling this we can implement this kind of toll collection system. Our system minimizes the problems faced by existing system. It will reduce unwanted traffic on highway roads and people will not have to wait for long hours for their part of payment.It will reduce burden of tax on common people. As the technology we are using is more reliable and accurate.

The following image shows the exact implementation of this project as shown in fig 6.
