3. 1.ABSTRACT: Toll gate Automation and Vehicle Tracking is designed to automatically keep track of the vehicle's movement, record the time and the details like Owner's name, date of registration, vehicle model etc. This system is very useful for automatic vehicle tracking, time management and also for automation of Toll gate. This paper explains the implementation of Toll Gate Automation which is a step towards improving the Tracking & monitoring of vehicles, traveling in predetermined routes. This system automatically identifies an approaching vehicle and records the vehicle number & Time. If the vehicle belongs to the authorized person/group, it automatically opens the Toll Gate and a predetermined amount is automatically deducted from its account.

4. 2.OBJECTIVE: This main goal of this project is authentication of the vehicle and the remaining all procedures of the tollgate should be done remotely. If the vehicle is unauthorized then it should activates the buzzer to indicate that is a thefted vehicle.

6. 4.METHODOLOGY: This project is developed for tollgate automation. The main modules in this project are IR transmitter and receiver, PIC decoder, ARM controller unit and output. The IR transmitter will be there in a vehicle and the IR receiver and the remaining module will be there in tollgate. When the vehicle comes near to the tollgate, first it will checks whether it is authorized or unauthorized. After authentication, if it is authorized then the person who is there in the vehicle has to press the buttons in the IR transmitter, then the IR receiver receives that signal and then PIC decoder decodes that signal, then based on the signal received the ARM controller will activates the output. If it is authorized it will opens the gate or else it will activates the buzzer.

7. 5.ADVATAGES AND DISADVANTAGES: ADVANTAGES:  This application is very useful in any place or area.  Manpower can be saved.  More reliable than man.  Enables very specific detection of vehicles.  Automatic collection of toll tax  Free flow of traffic.  Time saving.  Record maintenance.  Problems with pursuing toll evaders can be avoided.

8. DISADVANTAGES:  Low frequency results in lower maximum data rate,  Although it is fast enough to allow multiple transmissions to increase reliability.  Tag usually requires power from vehicle (active tag).  Tag installation is not as convenient as that of a windshield-mounted tag.  Moderate difficulty in duplicating tags.

9. 7.CONCLUSION: As this project is based on micro-controller(ARM7LPC2148), RF transmitter and receiver, PIC decoder and output. This project involves authentication of the vehicle and remaining all procedures of the tollgate will be done remotely.
