ELECTRONIC TOLL COLLECTOR:
Figure 1.1: Electronic toll
Electronic toll is an inter-operate-ability system allowing cashless payment at toll booths on national highways. It increases revenue, curbing leakages and ensuring smooth travel across the country.
The problem without Electronic toll system is that most people have to wait in the queue of slow moving vehicles of the toll booth. Other problems include delay in reaching the destination, time wasting, and cash exchange.
The main objective of E-toll project is to collect funds to finance the construction and maintenance of road network. In addition E-toll facilitates the delivery of sophisticated services based on information that the systems able to collect. The services include various things, from fleet management of private companies to directing traffic, avoiding traffic congestion or informing drivers about traffic jams and road accidents ahead of time. The E-toll system helps to avoid wasting of time. It will prove effective in tracking of stolen vehicles and cash exchange. It also avoids the delay in reaching the destination. Currently this technology is used in countries like U.S.A, Canada, Argentina, Mexico and Chile.
1.2 RFID:
Figure 1.2: RFID
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information modulating and demodulating (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal chip less RFID allows for discrete identification of tags without an integrated circuit, thereby allowing tags to be printed directly onto assets at a lower cost than traditional tags.
Electronic Toll Collection which is an automatic system does not require any personnel monitoring the operation. As RFID uses radio waves to communicate between the tag and the reader, the system is suitable for Electronic Toll Collection.
