SCHOOL BUS ROUTING MANAGEMENT SYSTEM
PROBLEM STATEMENT
1.1 INTRODUCTION
The Problem definition for the system is to develop software for “School Bus Routing
Management System” for Hope Hall Foundation School, based on feature - GIS (Geographic
Information System) Technique, in which School buses can be tracked on the way and software
also maintains database of Staff and students. Guardian can login to software using student’s id
and password.
1.2 WHAT WILL THE SOFTWARE DO?
School Bus Routing for School will ease the problem of scheduling and Routing School buses
that deals with the significant question of how to transport students to and from School.
Software keeps the real time record of each bus on the route.
User will be provided with the details of STUDENT(Student name, Father’s/Guardian’s name,
Residential address, Pick-up location and time, drop-off location and time, Student id, class, Bus
no.) ; DRIVER’S INFORMATION (Driver’s Name, Driver’s id, Residential address, Contact no.,
Bus no.), : CONDUCTOR INFORMATION(Conductor’s Name, Conductor’s ID, Residential
address, Contact number, Bus no.)TEACHER INFORMATION (Teacher’s Name, Class,
Teacher’s ID, Contact no., Bus no.). The Software allows Student to register to acquire facility
of School bus and Parents’ Login feature is also provided.
It should be designed to provide functionalities as follows:
• REGISTRATION:
Registration to the system will be provided by the software to the students. In this
step, Students have to register with their First name, Last name, Username,
Student ID, class, Parents’ name, contact no., Security question, Residential
address and password.
• LOGIN
Login Screen is the second Screen which will be shown to the user after creating
their profile. In this step, user (Admin/student’s parents) have to login with their
username and password to access the offline information or to track the bus. For
security reasons, students should have unique user id and password. In case of
student/Guardian forgetting their password, he/she can choose the “Forgot
Password” option. In this, user has to answer the security question in order to
change the password.
8

• TRACK
Software provides a feature called “TRACK” with the aid of GIS system. ‘Track’
will maintain the real time details like Traffic status, route followed by school
buses, distance covered, location and time.
Parents and school staff can access the location of student which helps the school officials to
maintain safety guidelines.
Transportation is one of the prime applications of GIS. GIS can be very helpful in making
school routes and in other school transportation services. “The greatest use of software
packages with an element, or component, of GIS technology is at an operational level e.g.
routing, scheduling, tracking, tracing or navigation.”[Forster 2000]
1.3 ADVANTAGES:
The existing fleet of buses and mini buses are currently managed manually. To improve the
existing fleet management system as well as decrease the maintenance costs, the software is
build supported by a GIS system.
a) Real time track of school bus.
b) Traffic status known beforehand.
c) Information of road construction and thus provides alternate route of
the destination.
d) Enables the pre-estimation of transportation time.
e) Economical and reliable.
In addition school transport management system may improve the transportation security as
guardian of student as well as school staff can track the school buses.

2: SOFTWARE PROCESS MODEL
WATERFALL MODEL:
School Bus Routing relies upon the WATERFALL MODEL and on the needs and requirements
of the user which were taken from initial module. The Waterfall Model will describe and
explain all the components which will assemble the Software.
The Model is applied because:
• Requirements are well-defined, clear and fixed.
• The phase’s proceeds in a systematic and sequential approach that begins at the
system level and proceed through analysis, design, coding, testing and support.
• Each phase has a review process.
• Each phase has well understood milestones.
• A working version of the software will not be available until late in the project
time-span which matches the needs of the client.
Once the Waterfall Model is designed and GIS data is gathered, the software is ready to
develop. Design focuses on a representation of those aspects of the software that will be visible
10

to end User. At the end of each phase, a review takes place to determine if the project is on the
right path and whether or not to continue or discard the project.

1.3.1 DEFINITIONS:
• GIS - Geographic Information System
Geographic Information System (GIS) is a computer system for capturing, storing, checking
and displaying data related to positions on Earth’s surface. It can show many different kinds of
data on one map. It also enables to easily see, analyze, and understand patterns and
relationships.
• GPS - Global Positioning System
GPS, which stands for Global Positioning System, is a radio navigation system that allows land,
sea, and airborne users to determine their exact location, velocity, and time 24 hours a day, in all
weather conditions, anywhere in the world.

8. PROJECT METRICS
A software metric is a standard of measure of a degree to which a software system or process
possesses some property. Product metrics provide with a systematic way to assess quality based
on a set of clearly defined rules. They provide on-the-spot, rather than after-the-fact, insight.
This enables to discover and correct potential problems before they become catastrophic
defects.
FUNCTION ORIENTED METRICS
The function point (FP) metric can be used effectively as a mean for measuring the
functionality delivered by a system. Function points are derived using an empirical relationship
based on countable (direct) measures of software’s information domain and qualitative
assessments of software complexity.
To compute function points (FP), the following relationship is used:
Evaluating function points (FP) value of a project with following information domain
characteristics:
 Number of User Inputs : 20
 Number of Output : 14
 Number of User Inquiry : 1
 Number of Logical Files : 9
 Number of External Interface : 1
Assuming the measurement parameters are equally divided among simple, average and
complex.

The Fi (i=1 to 14) are value adjustment factors (VAF) based on responses to the following
questions:
QUESTIONS VAF
1. Does the system require reliable backup and recovery? 3
2. Are specialized data communications required to transfer information to or
from the application?
3
3. Are there distributed processing functions? 3
4. Is performance critical? 3
5. Will the system run in an existing, heavily utilized operational environment? 3
6. Does the system require online data entry? 3
7. Does the online data entry require the input transaction to be built over multiple
screens or operations?
3
8. Are the ILFs updated online? 3
9. Are the inputs, outputs, files, or inquiries complex? 3
10. Is the internal processing complex? 3

12. Are conversion and installation included in the design? 3
13. Is the system designed for multiple installations in different organizations? 3
14. Is the application designed to facilitate change and ease of use by the user? 3
We evaluate, ∑ (Fi) = 42 (a moderately average product).
Therefore,
FP = 269 x [0.65 + (0.01 x 42)] = 287.83
Since, function point has been calculated it can be used to normalize measures for software
quality, productivity and other attributes such as:
 They can be used to size software applications accurately.
 Errors per FP
 Defects per FP
 Function Points can be used to determine whether a tool, a language, an environment, is
more productive when compared with others.

9. EFFORT ESTIMATION USING COCOMO MODEL
The COCOMO Model allows us estimate the cost, effort and scheduling when planning new
software development.
It consists of three sub models, each one offering increased integrity, further a long one is in the
project planning and design process. Listed increasing fidelity, these sub models are called the:
• Application Composition Model
• Early Design Model
• Post-Architecture Model
Since Our Software is based on Application Composition Model, We use COCOMO II
Software Model which includes the same (for early prototyping efforts) and the more detailed
Early Design and Post-Architecture models (for subsequent portions of the life cycle).
The COCOMO II Software model which is applicable uses object points
Object point is used to calculate indirect count measure that is obtained with number of
Screens, Reports, and 3GL components.
74
OBJECT TYPE
COMPLEXITY WEIGHT
SIMPLE MEDIUM COMPLEX
SCREENS
REPORTS
3GL COMPONENTS
2 7 4
1

Each Object instance is classified into three categories- Simple, Medium and Complex.
And the object count is obtained by the product of total number of object instances
obtained by weighing factor.
None of the components are being re-used in our Project and hence the %re-use here is zero.
As a Next step, we calculate New Object Point (NOP) by the following formula:
NOP = (Object Points)*[(100%-reuse)/100]
"Productivity Rate" is computed using the following formula to derive an estimate of effort
PRATE = NOP / person-month
And Estimated Effort = NOP / PRATE
COCOMO ESTIMATION FOR OUR PROJECT
Number of Screens = 13
Number of reports = 1
Object Points for Simple:
= [(13*2) + (1*0)] = 26
75
DEVELOPER’S EXPERIENCE/CAPABILITY

NOP = (Object Points)*[(100%-reuse)/100]
= 26 * [(100-0)/100]
= 26 * 1
= 26
Person Per month assumed = 3
Therefore, PRATE = 26/3
= 8.67
Estimated Effort = 26/8.6
= 2.99

10. PROJECT SCHEDULING
The project scheduling is the tool that communicates what work needs to be performed,
resources required and timeframes in which that work needs to be performed. The project
schedule is reflecting all the work associated with delivering the project on time.
