A Smart Approach to Number Plate Recognition in Tollgate System using FPGA

This paper reveals about the design and development of smart card for automated toll collection through number plate recognition. Since it is simpler and faster than the traditional token based ticket system, it has all the potential to replace the existing system. Moreover, it saves users valuable time by reducing the queue length in front of the toll counter. It is used to pay the amount automatically and open & close the toll gate automatically. We aim to reduce the time consumed to pay the toll gate amount and also to help the police department to trace the vehicle, incase if it was stolen or used for any illegal activities. As well as we are going to increase the security features in the toll gate because now a day's toll gate are the entrance to the main cities. If the Vehicle passed before paying the money the buzzer will automatically ring & the alert will be given to the police also. If any vehicle carries suspicious gas means the buzzer will ring so improved security than the existing systems. The entire system is developed as hardware based system using SPARTAN3 FPGA kit and associated devices. The software for this system has been developed using VHDL language developed in the Xilinx tool.
