The document proposes an Android application designed to improve public transportation in Pune by providing comprehensive bus information, including real-time tracking and route mapping. It aims to address the limitations of existing applications like 'Pune Bus Guide' that lack essential features, such as live location updates and accurate bus schedules. The system aims to enhance user experience and increase ridership through GPS tracking and a user-friendly interface.

CHAPTER 1
INTRODUCTION
There are buses made available for passengers travelling distances, but not many passengers
have complete information about these buses. Complete information namely the number of
buses that go to the required destination, bus numbers, bus timings, the routes through which
the bus would pass, time taken for the bus to reach, maps that would guide the passenger
with his/her route and most importantly, track the current location of the bus and give the
correct time for the bus to reach its bus stop. The proposed system deals with overcoming
the problems stated above. The system is an Android application that gives necessary
information about all the buses travelling in Pune. This information overcomes the problems
faced in the previously built application “Pune Bus Guide”. The platform chosen for this
kind of system is android, reason being Android Operating System has come up on a very
large scale and is owned by almost every second person. Also, Android is a user friendly
platform, thereby enabling ease of access for all the users. A number of applications made
for the Android Operating System is increasing on a large scale ever since its advent.
Android is an open source mobile software environment.
Brought up by Google, the operating system has been made Linux based and uses Java
programming language. It has a virtual machine that is used to optimize memory usage as
well as resources. This application has been developed using IDE (Android Studio 1.6) with
ADT (Android Development Tools) and Android SDK (Software Development Kit). There
are a number of constraints that need to be satisfied.

2. 2
1.1 Purpose
The main goal of the proposed work is to improve the Bus system by adding the necessary
additional features into the application, like accurate bus timings, correct bus numbers and
moreover adding a GPS tracker into it. This study accepts input in the form of selection of
the source and destination and selection of the bus travelling the distance to display the entire
details about the routes and also track the location of the respective bus and give the map for
the same.
The last two decades have seen growing interest in the development of Android based
platform. Our review of this area shows that there have been only few approaches that
provide automated tools for the functioning of the application:
1. An application has been implemented in Pune, named “Pune Bus Guide”. This application
gives the way to the destination correctly, but the number of drawbacks that it has is greater
than the number of advantages. It does not show the passengers current location even if
he/she is connected to the GPS. Also, this application has been proven useless as it does not
display the bus numbers, so the passengers find it very hard to know the number and time of
arrival of the respective buses. It does not have a real time bus tracking service or does not
even generate maps for the users ease. This application has never been updated ever since
its development. Moreover, this application has bugs which makes it all the more difficult
for the user to use it.
2. Another application that was implemented in Mumbai, named “M-Indicator – Mumbai”
has drawbacks like: It displays matter which is the same as what is online. Its latest updates
have given issues on every Android mobile supporting even the most recent device version.
The “A to B” module of buses has given problems. Whenever an option for the source to
destination is selected, the field still remains blank, i.e. no bus routes are displayed.
3. The application built in Delhi named “Delhi Bus Navigator” has drawbacks like: The
application works smoothly when offline, but works very badly when connected to the
Internet. The application gives information about direct routes only. It does not give
information about the alternate routes. This application has bugs due to which it lags all the
time. Most of the time the application crashes when requested for specific bus routes.

3. 3
4. The application developed in Bengaluru named “Bangalore BMTC Info” has drawbacks
like: The application is never in an updated condition. The application has fed in wrong
routes on several buses and given no updates to fix them. After the minimization and
restoration of the application, it cannot search anything. This application crashes almost
always. The application is not user friendly with a complicated User Interface (UI).
5. The application developed in Chennai named “Chennai Bus Route” has the following
drawbacks: The application works fine, but the bus timings have not been mentioned. Not
all bus stops are updated. The application does not display maps.
1.2 Scope
Many cities have found that GPS tracking system not only improve the efficiency of city bus
operation, but also encourage commuters to take the advantage of city bus system.
Many city bus system have discovered that GPS tracking system which allows to monitor
the location and arrival time of their bus actually increase the number of people using city
buses for routine communing.
The application is a user friendly one that anyone can access for free of cost. The basic idea
for this project was to guide the bus travelers with the routes, all the possible stops that come
on their way to the destination and moreover, display maps and track their locations and
show the estimate remaining time required to reach. The aim is to overcome all the
drawbacks faced in all the previous applications and generate fast and accurate results. The
proposed system has been divided into two modules as follows. Module 1 gives information
about all the routes from the source to the destination and give maps for the same. Module
2 give information about all the buses along with the bus numbers that go through the
selected stops, track the location of the selected bus and send this information to the
passenger giving him/her the estimate time required for the bus to reach. This is done using
the Client-Server technology.

4. 4
1.3 Software Development Life Cycle
The System Development Life Cycle framework provides system designers and developers
to follow a sequence of activities. It consists of a set of steps or phases in which each phase
of the SDLC uses the results of the previous one.
A Systems Development Life Cycle (SDLC) adheres to important phases that are essential
for developers, such as planning, analysis, designs and implementation and are explained in
the section below. A number of system development life cycle (SDLC) models have been
created: waterfall, fountain and spiral build and fix, rapid prototyping, incremental, and
synchronize and stabilize. The oldest of these, and the best known, is the waterfall model: a
sequence of stages in which the output of each stage becomes the input for the next. These
stages can be characterized and divided up in different ways, including the following:
 Project planning, feasibility study: Establishes a high-level view of the intended
project and determines its goals.
 Systems analysis, requirements definition: Refines project goals into defined
functions and operation of the intended application. Analyzes end-user information
needs.
 Systems design: Describes desired features and operations in detail, including screen
layouts, business rules, process diagrams, pseudo code and other documentation.
 Implementation: The real code is written here.
 Integration and testing: Brings all the pieces together into a special testing
environment, then checks for errors, bugs and interoperability.
 Acceptance, installation, deployment: The final stage of initial development, where
the software is put into production and runs actual business.
 Maintenance: What happens during the rest of the software's life: changes,
correction, additions and moves to a different computing platform and more? This,
the least glamorous and perhaps most important step of all, goes on seemingly
forever.

1.4 Feasibility Study
A feasibility analysis usually involves a thorough assessment of the operational (need),
financial and technical aspects of a proposal. Feasibility study is the test of the system
proposal made to identify whether the user needs may be satisfied using the current software
and hardware technologies, whether the system will be cost effective from a business point
of view and whether it can be developed with the given budgetary constraints. A feasibility
study should be relatively cheap and done at the earliest possible time. Depending on the
study, the decision is made whether to go ahead with a more detailed analysis. When a new
project is proposed, it normally goes through feasibility assessment. Feasibility study is
carried out to determine whether the proposed system is possible to develop with available
resources and what should be the cost consideration. Facts considered in the feasibility
analysis were-
 Technical Feasibility
 Economic Feasibility
 Behavioral Feasibility

6. 6
1.4.1 Technical Feasibility
Technical feasibility includes whether the technology is available in the market for
development and its availability. The assessment of technical feasibility must be based on
an outline design of system requirements in terms of input, output, files, programs and
procedures.
This can be qualified in terms of volumes of data, trends, frequency of updating, cycles of
activity etc., in order to give an introduction of technical system.
1.4.2 Economic Feasibility
This feasibility study present tangible and intangible benefits from the project by comparing
the development and operational cost. The technique of cost benefit analysis is often used as
a basis for assessing economic feasibility. This system needs some more initial investment
than the existing system, but it can be justifiable that it will improve quality of service.
Thus feasibility study should center along the following points:
 Improvement resulting over the existing method in terms of accuracy, timeliness.
 Cost comparison
 Estimate on the life expectancy of the hardware.
1.4.3 Behavioral/Operational Feasibility
This analysis involves how it will work when it is installed and the assessment of political
and managerial environment in which it is implemented. People are inherently resistant to
change and computers have been known to facilitate change. The new proposed system is
very much useful to the users and therefore it will accept broad audience from around the
world.

CHAPTER-2
SYSTEM ANALYSIS
To design and build a GPS tracking system for fleet based vehicles that will provide two-
way communications to the drivers. It uses following environment and tools for the
development of the project application. All the information is provided below.
In this chapter we will discuss about the Android architected in the form of a software stack
comprising applications, an operating system, run-time environment, middleware, services
and libraries. This architecture can, perhaps, best be represented visually. Each layer of the
stack, and the corresponding elements within each layer, are tightly integrated and carefully
tuned to provide the optimal application development and execution environment for mobile
devices.
2.1 Android
Android is a mobile operating system (OS) currently developed by Google, based on
the Linux kernel and designed primarily for touchscreen mobile devices such
as smartphones and tablets. Android's user interface is mainly based on direct manipulation,
using touch gestures that loosely correspond to real-world actions, such as swiping, tapping
and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input.
In addition to touchscreen devices, Google has further developed Android TV for
televisions, Android Auto for cars, and Android Wear for wrist watches, each with a
specialized user interface. Variants of Android are also used on notebooks, game
consoles, digital cameras, and other electronics. Now we have phones which can even access
GPS, GPRS, Wi-Fi, NFC and lot of other cool and advanced features which you cannot even
imagine. So in this Mobile world of this complication. Android is one of those operating
system platforms which made it easy for manufacturers to design top class phones.
Stored and copied to a stream where the actual data is transferred. Due to its native
characteristic, it runs in the background and waits for a possible transfer operation. They are
called right after the related button is pressed. Services retrieve values from static class called

8. 8
FinalValues.java through intent's extended data. They mainly include Final Values
.EXTRAS_GROUP_OWNER_ADDRESS and Android OS.
As it is widely known, android is a Linux-based operating system led by Google. It is mostly
developed for mobile devices to bring simplicity, functionality and efficiency to the market.
Android is an open source project and it has a large number of developers writing
applications. Developers write applications primarily in Java (Stephen Shankland, 2007) and
applications can be downloaded mostly through official online store called Google Play.
Currently there is 600,000 applications available on Google Play and so far 20 billion
applications downloaded from this store (engadget, 2012).
2.1.1 Overview
Android runs on Linux with libraries and libraries written in C. Dan Morrill, Android
Engineer in Google, explained that Android is not a specification, or a distribution in the
traditional Linux sense. It's not a collection of replaceable components. Android is a chunk
of software that you port to a device. (Dan Morrill, 2010)
Android uses the Dalvik Virtual Machine to run Dalvik Executable code translated from
Java bytecode. All standard APIs are defined in terms of classes, interfaces, methods and
objects. In terms of hardware platform, ARM architecture is main platform for Android.
However, there is also support for x86 architecture.
2.1.2 Architecture
Android runs on Linux under Dalvik VM. Dalvik has a just-in-time compiler where the byte
code stored in memory is compiled to a machine code. Byte code can be defined as
‘intermediate level'. JIT compiler reads the bytecode in many sections and compiles
dynamically in order to run the program faster. Java performs checks on dependent portions
of the code and thus the code is compiled only before it is executed. When it is compiled
once, it is cached and set to be ready for later uses.

Fig 2.1 Android Architecture

10. 10
2.2 Android Studio and Android SDK
Android Studio is the official IDE for Android app development, based on IntelliJ IDEA.
On top of IntelliJ's powerful code editor and developer tools, Android Studio offers even
more features that enhance your productivity when building Android apps, such as:
 A flexible Gradle-based build system
 Build variants and multiple APK file generation
 Code templates to help you build common app features
 A rich layout editor with support for drag and drop theme editing
 Lint tools to catch performance, usability, version compatibility, and other problems
 Code shrinking with ProGuard and resource shrinking with Gradle
 Built-in support for Google Cloud Platform, making it easy to integrate Google
Cloud Messaging and App Engine
Android provides a custom plug-in for Android development called Android Development
Tool (ADT). It is designed to build Android applications. It lets the developer to establish
new Android projects, build and debug applications, and export APKs.
2.3 SQLite Database
SQLite is a relational database management system contained in a C programming library.
In contrast to many other database management systems, SQLite is not a client–
server database engine. Rather, it is embedded into the end program.
SQLite is ACID-compliant and implements most of the SQL standard, using a dynamically
and weakly typed SQL syntax that does not guarantee the domain integrity.
SQLite is a popular choice as embedded database software for local/client storage
in application software such as web browsers. It is arguably the most widely
deployed database engine, as it is used today by several widespread browsers, operating

11. 11
systems, and embedded systems, among others. SQLite has bindings to many programming
languages.
2.4 GPS Tracking Unit
A GPS tracking unit is a device, normally carried by a moving vehicle or person, that uses
the Global Positioning System to determine and track its precise location, and hence that of
its carrier, at intervals. The recorded location data can be stored within the tracking unit, or
it may be transmitted to a central location data base, or Internet-connected computer, using
a cellular (GPRS or SMS), radio, or satellite modem embedded in the unit. This allows the
asset's location to be displayed against a map backdrop either in real time or when analyzing
the track later, using GPS tracking software. Data tracking software is available
for smartphones with GPS capability.
2.5 GPS Tracking Unit Architecture
A GPS tracker essentially contains a GPS module to receive the GPS signal and calculate
the coordinates. For data loggers it contains large memory to store the coordinates, data
pushers additionally contains the GSM/GPRS modem to transmit this information to a
central computer either via SMS or via GPRS in form of IP packets.
2.5.1 Fundamentals
The GPS concept is based on time and the known position of specialized satellites. The
satellites carry very stable atomic clocks that are synchronized to each other and to ground
clocks. Any drift from true time maintained on the ground is corrected daily. Likewise, the
satellite locations are known with great precision. GPS receivers have clocks as well;
however, they are not synchronized with true time, and are less stable. GPS satellites
continuously transmit their current time and position. A GPS receiver monitors multiple
satellites and solves equations to determine the precise position of the receiver and its
deviation from true time. At a minimum, four satellites must be in view of the receiver for it
to compute four unknown quantities (three position coordinates and clock deviation from
satellite time).

12. 12
2.5.2 Mobile Phones with GPS Capability
Due in part to regulations encouraging mobile phone tracking, including E911, the majority
of GPS receivers are built into mobile telephones, with varying degrees of coverage and user
accessibility. Commercial navigation software is available for most 21st-
century smartphones as well as some Java-enabled phones that allow them to use an internal
or external GPS receiver (in the latter case, connecting via serial or Bluetooth). Some phones
using assisted GPS (A-GPS) function poorly when out of range of their carrier's cell towers.
Others can navigate worldwide with satellite GPS signals as well as a dedicated portable
GPS receiver does, upgrading their operation to A-GPS mode when in range. Still others
have a hybrid positioning system that can use other signals when GPS signals are
inadequate.
2.5.3 Mobile Messaging
Mobile messaging plays an essential role in LBS. Messaging, especially SMS, has been used
in combination with various LBS applications, such as location-based mobile
advertising. SMS is still the main technology carrying mobile advertising / marketing
campaigns to mobile phones. A classic example of LBS applications using SMS is the
delivery of mobile coupons or discounts to mobile subscribers who are near to advertising
restaurants, cafes, movie theatres. The Singaporean mobile operator Mobile One carried out
such an initiative in 2007 that involved many local marketers, what was reported to be a
huge success in terms of subscriber acceptance.
Companies offering location-based messaging (sometimes referred to as "geo-messaging")
include The Coupons App (US), Central (International), Zhiing (international), BluePont
(US), Dodgeball (US) and Beamster (Austria).

CHAPTER 3
System Requirement Specification
A System Requirements Specification (abbreviated SRS when need to be distinct from
a Software Requirements Specification SRS) is a structured collection of information that
embodies the requirements of a system.
A business analyst, sometimes titled system analyst, is responsible for analyzing the
business needs of their clients and stakeholders to help identify business problems and
propose solutions. Within the systems development life cycle domain, the BA typically
performs a liaison function between the business side of an enterprise and the information
technology department or external service providers.
Software requirements specification establishes the basis for an agreement between
customers and contractors or suppliers (in market-driven projects, these roles may be played
by the marketing and development divisions) on what the software product is to do as well
as what it is not expected to do. Software requirements specification permits a rigorous
assessment of requirements before design can begin and reduces later redesign. It should
also provide a realistic basis for estimating product costs, risks, and schedules.
The software requirements specification document enlists enough and necessary
requirements that are required for the project development. To derive the requirements we
need to have clear and thorough understanding of the products to be developed or being
developed. This is achieved and refined with detailed and continuous communications with
the project team and customer till the completion of the software.

3.4 Device Permission Requirement
Map API requires some permissions in order to establish a connection. These must have
mention in Android manifest le. These permissions are:
 Internet
This permission is required for to access the internet using the application.
 ACCESS_COURSE_LOCATION
This permission is required for getting current location of user and bus using gsm
network
 ACCESS_FINE_LOCATION
This permission is required for getting current location of user and bus using gsm
network

CHAPTER 4
System Design
This chapter describes features, fragments, classes, architecture and the application itself by
providing necessary information of major components. First, an overall information is given
along with project's components and classes. Subsequently, the architecture details of the
application is discussed. Section 3.3 describes classes and methods under this sections.
4.1 Overview
Application starts with instantiating Location Manager. This is needed to track user location.
Detailed description regarding Location Manager is provided in this section. Next, UI and
user interaction handling sets up all necessary selections.
4.2 Components
In order to provide a detailed view concerning system mechanism, project can be
grouped in three segments. These are Location Manager, Fragments and AsyncTask &
Services.
The process in activity class and broadcast receiver intent, core fragments takes place where
they manage all handling and methods both in listing peers and establishing connection.
Core operations of the entire system is carried out with these two classes, namely as
MainActivity.java and GPSTracker.java
4.2.1 Location Manger
This class provides access to the system location services. These services allow applications
to obtain periodic updates of the device's geographical location, or to fire an application
specified Intent when the device enters the proximity of a given geographical location.
You do not instantiate this class directly; instead, retrieve it
through Context.getSystemService (Context.LOCATION_SERVICE).

17. 17
Unless noted, all Location API methods require
the ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permissions. If
your application only has the coarse permission then it will not have access to the GPS or
passive location providers. Other providers will still return location results, but the update
rate will be throttled and the exact location will be obfuscated to a coarse level of accuracy.
4.2.2 Fragments
Fragments handle core operations in this project such as Tracking, establishing connection,
opening sockets, showing details of buses. They are briefly responsible for managing all
session and configuring operations. Fragments also include asynchronous methods with
respect to file & text transfer as well as socket connection.
A Fragment is a piece of an application's user interface or behavior that can be placed in
an Activity and it represents a particular operation or interface that is running within a larger
Activity. A Fragment is closely tied to the Activity it is in, and cannot be used apart from
one. Though Fragment defines its own life cycle, that life cycle is dependent on its activity:
if the activity is stopped, no fragments inside of it can be started; when the activity is
destroyed, all fragments will be destroyed (Android, 2012).
Certainly, views can also be used in this regard. However, it is considerably reasonable
here to use fragments for some reasons. First of all, fragments are effective on creating
applications for various devices such as tablets and phones. If a developer desires to split
up views on different devices with different orientations and show them in two activities;
or show all the content as one on other devices, using fragment gives high edibility. In other
words, fragments can act as a small activity where it can essentially have multiple of them
on one screen.
Moreover, these multiple activities can cooperate and co-work in terms of communicating
with each other while they are visible. Thanks to its back stack management, pressing the
back button removes dynamically added fragments before the activity itself is eventually
finished. Lastly, it can have all sorts of services, operations such as AsyncTask, listeners,
and database access.

18. 18
4.2.3 AsyncTask & Services
Connection and data transfer operations are made by DeviceFragment.java class through
methods,
class SendPostReqAsyncTask extends AsyncTask<String, Void, String> {……}
AsyncTask process provides a simple way to maintain a background process with-out
working on other details such as threads and message loops. Its callback meth-ods help user
with scheduling tasks and updating UI. When a task executed, it goes through 4 steps.
However, in order to use AsyncTask class, at least one method, doInBackground(), must
be overridden. Methods are,
i. doInBackground() - This part runs in a seperate thread from the UI and con-
sists all the code which the application performs. It is called after onPreExecute
() and before onPostExecute().
ii. onPreExecute() - Called before thread starts running. It is used to setup a task
that is needed to be done in advance.
iii. onProgressUpdate() - Lets doInBackground() method pass data to UI thread.
iv. onPostExecute() - Runs after the background thread. It takes results from
doInBackground() method.
In this project, AsyncTasks are invoked on server side –
public void insertToDatabase(){…..} method in Server.java class - once a bus is assigned.
All tasks then go into a background process where the longitude and latitude of bus inserted
to server coming from services.

19. 19
Services are built for opening, binding a client socket and establishing connection between
server sides. When a connection is established, files and audio data is Final Values.
EXTRAS_GROUP_OWNER_PORT. Port numbers are determined as 8989 and 8988 for
audio data transfer and le transfer respectively.
Services and AsyncTasks are used in this study for particular reason. By definition, service
is used if there is a need for executing any long process in the back-ground. File sharing and
audio data transfer are maintained using service in order not to block any foreground process
and guarantee that the operation will not be interrupted. Services are best practice when there
are services for critical operation like sharing le or transferring data. On the other hand,
AsyncTasks provide a suit-able way to maintain background processing without handling
low-level details such threads, message loops. Its callback methods help to schedule tasks
and update interface when it is required. Since le sharing and audio data transfer are done
that are essentially isolated related to UI, using AsyncTask is best practice.
4.3 Block Diagram
Fig 4.1 System Block Diagram
Client has to enter in the application. To search for a bus, client has to enter the bus number
in the search bar. Then map is displayed which shows the current location of the bus. He can
also receive an alert notification when the bus came to the nearest stop. When the application
is launched, the home Activity fetches the routes from the server and binds it to the spinner

20. 20
for the client to select it. When the client selects a route, corresponding stops are fetched
from the server and binded to the spinner for the client to select. If the client selects “Track
Bus” then the location details of the bus for that route is fetched. If the client selects “Show
Map” then the location of the bus on the map will be displayed.

4.5 Data Flow Diagram
The DFD was first developed by Larry Constiane as a way of expressing system in a
graphical form. A DFD, also known as Bubble Chart, has a purpose of clarifying system
requirement and identifying major transformation that will become the programs in the
system design.
DFD SYMBOLS
1. A SQUARE defines a source or destination of system data
2. An ARROW identifies data flow or data in motion. It is a pipeline through which
information flow.
3. A CIRCLE or a BUBBLE (Some people use an over bubble) represents a process
transforms in coming data flow into outgoing data flow.
4. An OPEN RECTANGLE is a data store or data at rest or a temporary rest repository of
data.

We can express the overall logical structure of a database graphically with an ER diagram.
Its components are:
1 .Rectangles representing entity sets.
2. Ellipses representing attributes.
3. Diamonds representing relationship sets.
4. Lines linking attribute to entity sets and entity sets to relationship sets

CHAPTER 5
Implementation
Project is designed in four parts where each part is responsible for different aspects.
Essentially, main activity handles instantiate methods and pre-configuration process for
Location Manager class such as manage the previous location, current location, distance
between two location and status check whether GPS is on or off. It also consists standard
Android life cycle methods e.g. onPause(), onResume() and onDestroy(). Particularly,
onDestroy() and onKeyDown() functions manage post-configuration process in or-der to
set the device for regular use. Killing services and setting speaker o again can be named as
these processes.
5.1 Overview
Location based bus tracking system server should be auto start on installation or boot up.
Then it can find current latitude and longitude value with previous latitude and longitude
value, and store it to server database. Database manager use to manage the database of the
application, then user will check for the bus and gets information from database for that
particular location then application will behave according to user interface application will
simply allow user to add, delete, and update the database.

Fig 5.1 Working of a LBS Component
Using this application,
 The passengers can easily select bus route number and their stop from the list of bus
route numbers and know where the bus is and how long will it take to reach their
stop.
 They can also know the exact location of the bus on the Google Map which gives
them a better idea on the whereabouts of the bus.
 The list of bus routes and their corresponding stops can be managed using the website
which gives the admin a better hold on the application.
 This application helps the students and staff to track their buses and also college
authorities to manage efficiently.

5.2 Activity Diagram
Activity diagram is basically a flow chart to represent the flow form one activity to
another activity. The activity can be described as an operation of the system. So the control
flow is drawn from one operation to another. This flow can be sequential, branched or
concurrent.

5.3 Use-Case Diagram
A use case diagram at its simplest is a representation of a user's interaction with the system
that shows the relationship between the user and the different use cases in which the user is
involved. A use case diagram can identify the different types of users of a system and the
different use cases and will often be accompanied by other types of diagrams as well.

CHAPTER 6
TESTING
Testing is a process, which reveals errors in the program. It is the major quality measure
employed during software development. During software development. During testing, the
program is executed with a set of test cases and the output of the program for the test cases
is evaluated to determine if the program is performing as it is expected to perform.
6.1 TESTING STRATEGIES
In order to make sure that the system does not have errors, the different levels of
testing strategies that are applied at differing phases of software development are:
6.1.1 Unit Testing:
Unit Testing is done on individual modules as they are completed and become executable.
It is confined only to the designer's requirements.
Each module can be tested using the following two Strategies:
Black Box Testing:
In this strategy some test cases are generated as input conditions that fully execute all
functional requirements for the program. This testing has been uses to find errors in the
following categories:
 Incorrect or missing functions
 Interface errors
 Errors in data structure or external database access
 Performance errors
 Initialization and termination errors.

33. 33
In this testing only the output is checked for correctness. The logical flow of the data is not
checked.
White Box testing:
In this the test cases are generated on the logic of each module by drawing flow graphs of
that module and logical decisions are tested on all the cases. It has been uses to generate the
test cases in the following cases:
 Guarantee that all independent paths have been executed.
 Execute all logical decisions on their true and false Sides.
 Execute all loops at their boundaries and within their operational bounds
 Execute internal data structures to ensure their validity
6.1.2 Integrating Testing:
Integration testing ensures that software and subsystems work together a whole. It tests the
interface of all the modules to make sure that the modules behave properly when integrated
together.
6.1.3 System Testing:
Involves in-house testing of the entire system before delivery to the user. Its aim is to satisfy
the user the system meets all requirements of the client's specifications.
6.1.4 Acceptance Testing:
It is a pre-delivery testing in which entire system is tested at client's site on real world data
to find errors.

6.2 Test Approach
Testing can be done in two ways:
6.2.1 Bottom up Approach:
Testing can be performed starting from smallest and lowest level modules and proceeding
one at a time. For each module in bottom up testing a short program executes the module
and provides the needed data so that the module is asked to perform the way it will when
embedded within the larger system. When bottom level modules are tested attention turns to
those on the next level that use the lower level ones they are tested individually and then
linked with the previously examined lower level modules.
6.2.2 Top down approach:
This type of testing starts from upper level modules. Since the detailed activities usually
performed in the lower level routines are not provided stubs are written. A stub is a module
shell called by upper level module and that when reached properly will return a message to
the calling module indicating that proper interaction occurred. No attempt is made to verify
the correctness of the lower level module.
6.3 Validation and Verification:
The system has been tested and implemented successfully and thus ensured that all the
requirements as listed in the software requirements specification are completely fulfilled. In
case of erroneous input corresponding error messages are displayed.
In software project management, software testing, and software engineering, verification and
validation (V&V) is the process of checking that a software system meets specifications and
that it fulfills its intended purpose. It may also be referred to as software quality control. It
is normally the responsibility of software testers as part of the software development
lifecycle.

Validation checks that the product design satisfies or fits the intended use (high-level
checking), i.e., the software meets the user requirements. This is done through dynamic
testing and other forms of review.
Verification and validation are not the same thing, although they are often confused. Boehm
succinctly expressed the difference between
Verification: Are we building the product right?
Validation: Are we building the right product?
According to the Capability Maturity Model (CMMI-SW v1.1),
Software Verification: The process of evaluating software to determine whether the products
of a given development phase satisfy the conditions imposed at the start of that phase[IEEE-
STD-610].
Software Validation: The process of evaluating software during or at the end of the
development process to determine whether it satisfies specified requirements[IEEE-STD-
610].
In other words, software verification is ensuring that the product has been built according to
the requirements and design specifications, while software validation ensures that the
product actually meets the user's needs, and that the specifications were correct in the first
place. Software verification ensures that "you built it right" Software validation ensures that
"you built the right thing". Software validation confirms that the product, as provided, will
fulfill its intended use.
From testing perspective:
Fault – wrong or missing function in the code.
Failure – the manifestation of a fault during execution.
Malfunction – according to its specification the system does not meet its specified
functionality.

FUTURE SCOPE
 This project will be put up on the cloud platform, so that it will be accessible by every
Android user.
 The application will prove beneficial for every bus traveler, or even tourists. Not just
buses, but this application will be useful for every person travelling by any means of
transport.
 The Location Tracker will give the exact location of the bus which will make it easy
for the passengers to travel.

CHAPTER 9
CONCLUSION
The conclusions of this study suggest that knowledge of specific domain improves the
results. This Project has been implemented on Android platform. Also, different attributes
have been added to the project which will prove to be advantageous to the system. The
requirements and specifications have been listed above. This project is implemented using
Android and the SQL domain. Using the GPS system, the application will automatically
display the maps and routes to the different locations and also track the bus location using
client-server technology and forward it to the client device. It uses basic measurements of
distance between two locations and provides necessary details of each and every route for
people to easily pick up buses or any other conveyance possible on the specified route.
Specific location details are provided to the user along with bus no. so that the person can
identify the bus correctly. It uses remote server as its database. Due to this the records can
be easily manipulated on the device itself and the server burden gets reduced.
