    ABSTRACT

    Electronic toll collection (ETC), an adaptation of military identification friend or foetechnology, aims to eliminate the delay on toll roads by collecting tolls electronically.

    ETC determines whether the cars passing are enrolled in the program, alerts enforcers forthose that are not, and electronically debits the accounts of registered car owners withoutrequiring them to stop.

    In 1959, Nobel Economics Prize winner William Vickrey was the first to propose a

    system of electronic tolling for the Washington Metropolitan Area. He proposed that each

    car would be equipped with a transponder. The transponders personalised signal wouldbe picked up when the car passed through an intersection, and then relayed to a central

    computer which would calculate the charge according to the intersection and the time of

    day and add it to the cars bill Electronic toll collection has facilitated the concession tothe private sector of the construction and operation of urban freeways, as well as made

    feasible the improvement and the practical implementation of road congestion pricingschemes in a limited number of urban areas to restrict auto travel in the most congested

    areas.

    In the 1960s and 1970s, free flow tolling was tested with fixed transponders at the

    undersides of the vehicles and readers, which were located under the surface of the

    highway.

    Norway has been the world's pioneer in the widespread implementation of thistechnology. ETC was first introduced in Bergen, in 1986, operating together with

    traditional tollbooths. In 1991, Trondheim introduced the world's first use of completely

    unaided full-speed electronic tolling. Norway now has 25 toll roads operating withelectronic fee collection (EFC), as the Norwegian technology is called (see AutoPASS).

    In 1995, Portugal became the first country to apply a single, universal system to all tolls

    in the country, the Via Verde, which can also be used in parking lots and gas stations.

    The United States is another country with widespread use of ETC in several states,though many U.S. toll roads maintain the option of manual collection.

    1: LITERATURE SURVEY

    1.1 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 queueof 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 sophisticatedservices 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 oftime. 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 andChile.

    CHAPTER 2

    INTRODUCTION

    AIM

    Electronic toll collection (ETC), an adaptation of military "identification friend or foe"

    technology, aims to eliminate the delay on toll roadsby collecting tolls electronically.

    ETC determines whether the cars passing are enrolled in the program, alerts enforcers for

    those that are not, and electronically debits the accounts of registered car owners without

    requiring them to stop.

    OBJECTIVE

    The main objective of this project is collecting toll and reduce traffic and improve

    service. The RFID card will be given to the user which contains the digital code, which

    have to the corresponding details stored in the centralized database system which can be

    accessed in the relevant office as and when required. Radio-frequency Identification

    (RFID) is an automatic identification method, relying/storing and remotely retrieving

    data using called RFID tags (Transporters). An RFID tag is an object that can imbibe into

    a product, animal, or person for the purpose of identification using radio waves. Some

    tags can be read from several meters and also can be used beyond the line of sight of the

    reader. The model developed uses an active RFID technology and wireless communicator

    as it helps to improve data transfer between the tag and the host database over a long

    distance. The main objective of this module development is to implement an automated

    check in and checkout in Electronic Toll collection system. Electronic toll collection

    system (ETC) is one of the means that have been adopted by all developed countries to

    solve jam problem by parking charge and improve service quality. However the system

    can also be used in car alarms, warehouse inventory, security access control, personnel

    access & tracking without the need to swipe each item individually.

    VISION

    Project vision encompasses enabling every rental vehicle residing within an electronic

    toll collection system with the ability to pay for tolls automatically, whether transponder

    or video toll based.

    CHAPTER 3:

    PROJECT/PROBLEM SELECTION

    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 thedestination, time wasting, and cash exchange.

    With the use ofElectronic Toll Collector (ETC) the throughput of the system can beincreased three times. For that reason, ETC systems might represent a more feasible

    alternative than building additional toll lanes. One of the key factors for all the ETC

    projects is to calculate the benefits that it might produce before the actual

    implementation. There is a dearth of research done in integrating all the benefits for ETC.Previous studies show that the benefits for ETC are evaluated on an individual basis. In

    addition, since most of these projects are relatively new, the benefit analysis has been

    done with less accuracy.

    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 sophisticatedservices 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 oftime. 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.

    By using Electronic toll system in toll booth we will get the following benefits-

    Increases patron convenience and safety with nonstop payment Improves traffic flow

    Reduces patron commute time

    Reduces traffic congestion Lowers patron fuel use

    Reduces emissions which are a major cause of pollution

    Reduces need for new roads Reduces operating costs for toll authorities

    Provides proven reliability and unparalleled accuracy

    CHAPTER 5

    SYSTEM STUDY

    5.1 EXISTING SYSTEM ALONG WITH LIMITATIONS/DEFICIENCIES

    Exiting system is limited to Undetected Incorrect Reads referring to the incorrectread of a tag that the registration hardware or software does not catch. This scenario

    constitutes either a free ride for the motorist, or an undeserved fine for failure to pay

    which can be a hefty price.

    Theft the tags are, in essence, electronic money and therefore there will be

    motivation to steal them. Specially-designed tags that are permanently affixed to thewindshield have been created to deter anyone from trying to remove it without damaging

    the tag.

    A customers account can be subjected to hackers.

    Job loss- attendants will be replaced with electronic tolls.

    5.2 PROPOSED SYSTEM ALONG WITH INTENDED OBJECTIVES

    User Friendly: We have tried to come up with the project which is as much user friendly

    as it can. The administrator will have no problem in running the project.

    Security: The Project determines whether the cars passing are enrolled in the program,alerts enforcers for those that are not, and electronically debits the accounts of registered

    car owners without requiring them to stop..

    Uniqueness: In this Project RFID tag will be a prepaid tag which will be affixed in theupper central portion of the vehicle's windscreen. It will work as a prepaid toll account

    and there will be automatic toll deduction when the vehicle crosses a toll plaza.

    The unique number of the Tag fitted on the windscreen of the vehicle would be read by

    the 'readers' fitted in the dedicated "ETC" lanes of these plazas, and sent to the CentralClearing House.The user will get an instant SMS alert as well as email update. The

    Clearing House pools the money collected electronically and later distributes among toll

    plaza managements as per usage by vehicles.

    5.3 FEASIBILITY STUDY

    The feasibility study is carried out to test if the proposed system worth beingimplemented. Given unlimited resources and infinite time, all projects are feasible. Hence

    it become booty necessary and prudent to evaluate the feasibility of the project at the

    earliest possible time in order to avoid unnecessary wasted of time, effort andprofessional embarrassment over an all - conceived system. Feasibility study is a test of

    8

  • 7/28/2019 electronic toll collector

    14/32

    system proposed regarding its workability, impact on the organization ability to meet us

    need and effective use of resources. It is usually carried out by the small group of peoplewho are familiar with the information system technique, understand the part of the

    business or organization that will be involved or affected by the project, and are skilled in

    the System Analysis and Design process. The purpose of feasibility study is not to solvethe problem but to determine if the problem is worth solving.

    Feasibility usually includes the following aspects:

    5.3.1OPERATIONALIt is operationally feasible in its nature also, because it is developed in Java and Ms

    Access of which Java provides user-friendly environment due to its features.

    The System will provide them automatic reporting and checks on entries while storing aswell as entering. So the front end has been made user friendly for Administrator.

    5.3.2 TECHNICAL

    The Technical issues usually raised during the feasibility stage of the investigation

    include these:-

    Does the necessary technology exist to do what is suggested?Does the proposed equipment have the technical capacity to hold the data required to use

    the new system?

    Can the system be expanded if developed?Are there technical guarantees of accuracy, reliability, ease of access and data security?

    Processor used in this project is Intel Core i3 CPU M370 @ 2.40GHz, 3.2GBRAM.

    System type- 64 bit operating system.

    Software like Java, Ms-Access, Text pad and operating system WINDOWS-7 HomeBasic were already installed on the existing computer system. So no additional hardware

    and software were required to purchase and it was technically feasible.

    The aspects of our study included the following factors.

    1. FRONT-END SELECTION:

    It must have servlet, swing and concepts of multithreading that

    assists employees that are not from IT background.

    Scalability and extensibility.

    Flexibility.

    Robustness.

    According to the organization requirement and the culture.

  • 7/28/2019 electronic toll collector

    15/32

    Must provide excellent reporting features with good printing

    support.

    9

    Platform independent.

    Easy to debug and maintain.

    Event driven programming facility.

    Front end must support some popular back end like SQL Server.

    According to the above stated features we selected JDK as the front-end for developing

    our project.

    2. BACK-END SELECTION:

    Ms-Access

    Multiple user support.

    Efficient data handling.

    Provide inherent features for security.

    Efficient data retrieval and maintenance.

    Stored procedures.

    Popularity.

    Operating System compatible.

    Easy to install.

    Various drivers must be available.

    Easy to implant with the Front-end.

  • 7/28/2019 electronic toll collector

    16/32

    According to above stated features we selected Ms-Access as the backend. The technical

    feasibility is frequently the most difficult area encountered at this stage. It is essential thatthe process of analysis and definition be conducted in parallel with an assessment to

    technical feasibility. It centers on the existing computer system (hardware, software etc.)

    and to what extent it can support the proposed system.The technical requirement for our proposed system is economic and it does not use any

    other additional Hardware and software.

    5.3.2 ECONOMIC

    Economic feasibility is the study of both whether or not the technology can be

    afforded and whether it is cost-effective, meaning the benefits out weight the costs.

    The proposed system is economically feasible because the cost involved inpurchasing the hardware and the software are within approachable. The personal

    cost like salaries of employees hired are also nominal, because working in this

    system need not required a highly qualified professional.. The less time involvedalso helped in its economical feasibility.

    Entity Relationship Diagram

    An entity-relationship (ER) diagram is a specialized graphic that illustrates the

    interrelationships between entities in a database. ER diagrams often use symbols torepresent three different types of information. Boxes are commonly used to represent

    entities. Diamonds are normally used to represent relationships and ovals are used to

    represent attributes.

    Entity Relationship (ER) diagram:

    This diagramming technique is used to visually present a database schema or data

    model and was original proposed by Chen in the 1970s. There are many different data

    modeling notations; some are very similar to UML class diagrams (with the exception ofoperations). However, the notation the used here is slightly different, as proposed by

    Elmasri, et al.

    The database schema for this system is shown in figure. The table object has been left out

    of the diagram because the table management feature set had been dropped from therequirements before this stage of the design process.

    Some important database design decisions are as follows:_ To store the total price of an order with the order rather than calculating it on the fly

    when looking at past orders. This is because the price of menu items could change at any

    time, so the total price at the time of ordering must be stored so that the total price is notincorrectly calculated in future.

    _ Similar to the previous point, the order receipt is stored as a hard-copy and notregenerated when reviewing past orders because things such as the restaurant name or

    VAT percentage are subject to change. Receipts stored need to be exactly the same as the

    customer copy in case of dispute.

    MODEL USED

    ITERATIVE MODEL

    An iterative life cycle model does not attempt to start with a full specification of

    requirements. Instead, development begins by specifying and implementing just part of

    the software, which can then be reviewed in order to identify further requirements. Thisprocess is then repeated, producing a new version of the software for each cycle of the

    model.

    For example:

    In the diagram above when we work iteratively we create rough product or product piecein one iteration, then review it and improve it in next iteration and so on until its

    finished.Diagram of Iterative model:

    Advantages of Iterative model: In iterative model we can only create a high-level design of the application before

    we actually begin to build the product and define the design solution for the entire

    product. Later on we can design and built a skeleton version of that, and then evolvedthe design based on what had been built.

    In iterative model we are building and improving the product step by step. Hence

    we can track the defects at early stages. This avoids the downward flow of thedefects.

    In iterative model we can get the reliable user feedback. When presenting

    sketches and blueprints of the product to users for their feedback, we are effectivelyasking them to imagine how the product will work.

    In iterative model less time is spent on documenting and more time is given for

    designing.

    Disadvantages of Iterative model:

    Each phase of an iteration is rigid with no overlaps.

    18

  • 7/28/2019 electronic toll collector

    25/32

    Costly system architecture or design issues may arise because not all requirements

    are gathered up front for the entire lifecycle.

    When to use iterative model:

    Requirements of the complete system are clearly defined and understood. When the project is big.

    Major requirements must be defined; however, some details can evolve with time.

    TESTING USED

    WHITE BOX TESTING

    White box testing is used to test areas that cannot be reached from a black box level.

    White box testing (a.k.a. clear box testing, glass box testing or structural testing) uses an

    internal perspective of the system to design test cases based on internal structure. Itrequires programming skills to identify all paths through the software. The tester chooses

    test case inputs to exercise paths through the code and determines the appropriate outputs.

    In electrical hardware testing, every node in a circuit may be probed and measured; anexample is in-circuit testing (ICT).

    Since the tests are based on the actual implementation, if the implementation changes, the

    tests probably will need to change too. For example ICT needs updates if component

    values change, and needs modified/new fixture if the circuit changes. This adds financialresistance to the change process, thus buggy products may stay buggy. Automated optical

    inspection (AOI) offers similar component level correctness checking without the cost of

    ICT fixtures; however changes still require test updates.

    While white box testing is applicable at the unit, integration and system levels of the

    software testing process, it is typically applied to the unit. While it normally tests paths

    within a unit, it can also test paths between units during integration, and betweensubsystems during a system level test. Though this method of test design can uncover an

    overwhelming number of test cases, it might not detect unimplemented parts of thespecification or missing requirements, but one can be sure that all paths through the test

    object are executed.
