Submitted by Anoop.K.S. Harikrishnan.M.A. Pattabiraman.R.
Scope of the Project: The project Vehicle Tracking & Ticketing System (VTTS) mainly deals with identification of vehicles and ticketing the passengers using these vehicles. The project is implemented with the help of Radio Frequency Identification (RFID) Technology. The major area of implementation o f our project is for ticketing bus passengers in college bus electronically and obtain identification of buses. The project on implementation will fetch added features like speed in transaction, cost efficiency, low frequency of errors etc. Another added f eature will be the accuracy in data recorded. Human errors will be rectified to the maximum thereby enhancing the efficiency of the system. The obsolete system of manual entry and calculation can be removed and this method could be adopted to bring into a ction a more efficient system. This VTTS application identifies a particular vehicle by the RFID tag fixed on them. In case of passenger boarding or getting down the bus is identified and ticketed on the basis of ID card they posses. The system could be more elaborately established for all vehicles and passengers and a complete digital network could be established with the least of its possible errors. The tags are cost efficient and the whole equipment once installed can work without any particular attent ion. The area of application of RFID is very wide and the technology has already proved its value. Thus the implementation and practice of such a digital system would always be worth.
Description of the Concept: VTTS is designed to work in an environment where vehicle identification is required. The prototype made is having all the features of the whole project. The current prototype made is to support the needs and requirements of our college. It could easily serve as a model of the whole working project. Moreover a complete functional database is ready to deliver. The technical details regarding the project are described. Radio Frequency Identification is a generic term for technologies that use radio waves to automatically identify people or objects. An RFID system consists of a tag, which is made up of a microchip with an antenna and an interrogator or reader with an antenna. The reader sends out electromagnetic waves. The tag antenna is tuned to receive these waves. A passive RFID tag draws power from field created by the reader and uses it to power the microchip's circuits. The chip then
modulates the waves that the tag sends back to the reader and the reader convert the new waves into digital data. For the purpose of Vehicle Identification, the tags ar e embedded into the Vehicle. The reader sends the electro magnetic waves to the tag. The tags draw the power from this wave and return back the vehicle information, which are stored in its memory to reader. The readers again demodulate this wave and conver t it as a digital data. For the purpose of Ticketing, the operational feature of the cards is the same but here the tags are attached to the Student ID cards and the reader collects the detail from them. Schematic representation of RFID technology used in VTTS is given below in figure 1. with a sequential indications to the various features used by the system. The antenna senses the tag and the information are fed into the reader. The reader then decodes these data and sends it to the host system through requires means.

Unique Features of the Proposed Project: The implementation of RFID for vehicle identification and ticketing was executed to overcome the various shortcomings in the existing system. Some of the added features in this system are listed below:
Generally, the BARCODE
technology uses the ‘line of sight’ technology. That is, a
scanner has to “see” the bar code to read it, which means people usually have to orie nt the bar code towards a scanner for it to be read. Radio frequency identification, by contrast, doesn’t require line of sight. RFID tags can be read as long as they are within range of a reader.
Actually, the RFID uses the low -end of the electromagnetic spectrum. Thus waves coming from readers are not dangerous and are similar to those waves coming from our car radio. Just as our radio tunes into different frequency to hear different channels, RFID tags and readers are tuned to the same frequency to commu nicate.
Radio waves travel through most non -metallic materials, so they can be embedded in packaging or encased in protective plastic for weatherproofing and greater durability.
Alternatives Thought of While Designing the Project: Manual Ticketing and vehicle identification was the obsolete method available but the frequency of getting errors and mismatch in entries was a serious problem. Human employment was always over ruled by computers. The factor of fatigue will also be overruled. An interesting area applicable in a similar situation was the BARCODES. But this had the major problem of line of sight that is the coded card had to be taken to the reader to validate an entry. Even though the method is bit less expensive the security that could be offered was very less. Another technique for implementing such a request is by using Biometric devices. But the comparative cost of implementation is very high and the system being dependent on physiological characteristics will not function effectively as expect ed if there is an unexpected change in the physiological characters of the client.
Cost/Benefit Expected Consumers usually welcome price reduction. For that to be enduring, the supplier and retailer must reduce costs. RFID on buses, cards are achieving this in many ways but the tagging of individual items is revealing yet richer rewards, even though it is at a much earlier stage. Automation is the key, but it comes alongside crime reduction, reducing excess stocks and work in progress and reducing the ti me taken from raw materials to finished item on the retailer’s shelf
(“time to market”) and other benefits that directly impact costs. The estimated cost for the implementation of the project mentioned will figure out around INR 10,000 -15,000. It will have a considerable contribution towards saving the manual scanning, administrative errors, etc. It will increase the rate of efficiency by introduction of a common conduct of operation that will enable the administrators to fabricate a less crime -sensed system. The number of trespassers and other unidentified persons could easily be tracked using the system.
The various benefits expected could be summed up as
Speed of transaction
Increased safety
Cost reduction
Fewer queues
Easier evacuation
More reliable equipment
Less frustration.
Less violent crime.
Faster processing of passengers.
Reduces fraud.
Greater reliability of equipment.

Vehicle tracking and ticketing is just a low level application to imprint the wide level of application possible in this field. The implementation in college transport section would make it easy for the detailed study of various aspects of the project.

Approach to implementation: The vehicle ticketing and tracking system is applicable under normal environmental conditions. The users/clients are provided with a RFID tag enabled card having their details printed as usual. The RFID tag will b e saved with information regarding the user previously. This forms basically forms the input for the system. The passengers while boarding or getting down the bus are made to pass by a RFID reader fixed somewhere on the way. The readers read the cards with the passengers and the data is fed into the local terminal. The details of the client are matched with the database in the server and later the observations are recorded accordingly. A user/client who pays an initial amount is given a minimum permit to use the bus. This is accounted in terms of chances he uses the bus. He can use the account until he finishes his quota that has been allotted to him. A diagrammatic representation of the proposed system to be implemented is given in Figure2.The computer term inals shown in the Figure2 are optional and the prototype made is functional directly on the server.

Issues to be confronted: The server should always be in working condition and proper connectivity of server with computer terminals should be assured. Passengers should be checked to have proper cards that could be read by the tag while boarding or else provision should be given to issue cards for everyone. Selection of frequency of the tags and the reader is a major issue and it should be properly taken care of. The tags are having a proprietary technology and the tags may not be sensible inside some other readers. The range of the reader and tag plays an important role and hence the tags and reader should be confirmed of contact.
Tag collision or reader collision is ano ther important factor that causes malfunctioning of the whole system. Trespassers should be taken care of or else the system may not be that effective.
