Problem Statement
Problem Analysis:-
1. We don’t have system which could inform Passenger about their Bus Timing, Shedule
etc.
2. We only do have record of bus Timings on which bus should start on a route which is
also sometimes not followed by drivers.
3. There is no information provided to passenger about buses.
Method of Solution:-
1. The problem of bus timing and other problem could be solved by Schedule Monitoring
of Buses.
2. Real time Information should be provided to user about their bus this could be done
by using GPS in buses.

1 INTRODUCTION
1.1 Purpose
The GPS Based Bus Management System (GBMS) is used to keep Track of Buses by
Company. Also this facility can be used to give information to Passenger by web and a
Display on Bus Stop.
1.2 Scope
Many cities have found that using GPS tracking systems not only improve the efficiency of
city bus operations, but also encourage more commuters to take advantage of their city bus
systems.
Many city bus systems have discovered that GPS tracking systems which allow passengers to
monitor the location and estimated arrival time of their bus actually increases the number of
people using city buses for routine commuting. For example, if a rushed commuter can
1.3 Definitions
Our System also provides information about Buses to Passenger. Consider the possibility of
implementing GPS tracking systems which allow customers to monitor bus locations via
website, or cell phones. This will likely increase the satisfaction of customers. Also a display
is fixed on every Stop so passenger will know where their bus is and when will it arrive.
1.4 Overview
The purpose of this section is to obtain agreement regarding the objectives the system must
meet. Ultimately this segment defines the boundaries of the effort. The “GPS Based Bus
Management System” helps administrator honor their professional commitments by
following a tailored version of the organization’s standard process. This project aims to
provide helpful information about Bus in a given geographic area. Also it store Tracking
Information in Database. It also keep track of Bus’s speed if it is crossed the authority will
get the information.verify his or her bus is running on time via their cell phone or a website,
they are much more likely to ride the bus rather than take a cab or drive themselves.

FP (EST.) = 102 * 1.03
= 105.06
 Our average productivity is 8 FP/month.
 If labour rate is Rs.10000 per month.
 Cost per FP is Rs. 1250.
 Total Cost for Project is Rs. 130,000.

S.No RISK CATEGORY PROBABILIT
Y
IMPACT RMMM PLAN
1 Some team members
leave the project
development in-
between
Technical risk 30% 2  Use backup staffs
which knows what was
going on in the project.
2 Delivery deadline
tightened
Project risk 30% 1  Team may use extra
members to complete
the task on scheduled
time
3 Losing of all the project
data, this may be
caused by a hard disk
being wiped out by a
virus, hard disk failure,
etc.
Project risk 20% 2  Carry out necessary
backup of database
data, source code and
documentation
4 Team dissension/lack of
cohesion
Project risk 10% 3  We could set some
guide-lines and rules
regarding how we deal
with each other .

Input : ID, Password.
Process : Click on the login link. If administrator enters ID and password correct it goes to
the admin services otherwise displays the same page with an error message.
Output : Displays the admin services page.
2. Test case: Add/Delete new Bus
Input: Bus_Id.
Process: A new Bus can be added into the system and admin can update details.
Output: Changes will take place in Database
3. Test case: Add/Delete new Route
Input: Route_id
Process: A new Route can be added/deleted into the system and admin can update details.
Output: Changes will take place in Database
4. Test case: Track a Bus
Input: Bus_Id
Process: All GPS Message coming from this bus ID will be displayed through Map.
Output: Real Time tracking will be shown on Map.
