Abstract

A short-range communication technology is currently applied in al- most all
electronic toll collection. An automated toll system is implemented and the amount of
transaction is sent to the driver’s mobiles through GSM modem. This technology is novel
aimed at easy toll collection systems especially in ex- pressways. The objective of this study
is to construct a model which can be used for automatic identification of the registration
number of the approaching vehicle along with time. If it is an authorized person’s vehicle
then the gate will open by itself and toll tax will be debited from the user’s account. In case
of entering without permission, then it will be recorded and warning signals will be given.
An RFIDtag containing the vehicle specific identification number will be present in all
vehicles. The amount will be debited and the remaining amount will be updated as the
vehicle passes through the toll gate. An update of negative balance will be provided in case
of inadequate amount in the prepaid account. All details are shared between the FASTag
holders and the authorized toll collection per- sonnel, so that there can be an effective toll
collection and simultaneously avoid- ing long queue of vehicles and chances for human
error. FASTag is a user- friendly, reloadable tag that helps in deducting toll charges
automatically. This system allows you to cross the toll booth without having a need to wait
for cash transaction. FASTag is connected to a prepaid account from which the certain toll
amount is deducted when the vehicle passes through the toll gate. The pro- posed system
makes use of Radio-Frequency Identification (RFID) tag, which is affixed on the
windscreen of the vehicle. FASTag is the right solution for a prob- lem-free trip on national
highways. However, in the existing system, when other users use the FASTag, it cannot be
identified whether it belongs to a particular person or not and the amount is also deduced.
In the proposed system the Image Processing technique Optical Character Recognition
(OCR) algorithm is used to sense the number plate of a vehicle and then it is matched with
a database to provide correct information, and the amount transaction is done consistently.
