Tracking System
The tracking system consists of a GPS unit that tracks the location of the vehicle
using satellite signals. The information from the GPS unit shall be transmitted to
the computer via the USB port.
Processing Station
The processing unit is simply a laptop computer serving as a substitute
microprocessor due to financial limitations. The computer will receive data from
the sensing unit via the serial port and from the tracking unit via the USB port.
This information is then processed by the program written by the team. In the
event of an accident, this program will detect the high output from the
comparator, retrieve the vehicles location from the GPS unit, place a call to the
call center via the cell phone and relay the information to the call center. The
computer is owned by a team member and adds no extra cost to overall budget.
Communications Unit The communications unit shall be either a cell phone connected externally to the
lap top or the phone dialer program contained within the laptop. In either case,
the device simply places a call to the call center in the event of an accident. Both
the phone dialer and the cell phone are already owned by team members and
therefore add no extra cost to the team’s budget.

Section 4 – Estimated Resources and Schedules Within this section are the estimated resources and schedules.
4.1 Estimated resources In this section the resources necessary to complete the project are defined. 4.1.1 Personnel effort requirement The personnel effort is the estimated amount of time each team member will
spend on a specific task within the project. The progress of the project and the
amount of time each team member has spent to date will be documented in the
weekly email sent by the communications coordinator to the other team members
and the faculty advisors.
Problem definition
This task will analyze the proposed problem and create a concise and complete
definition of the problem statement. As the requirements, design, and technology
specifications change so may the original problem definition; therefore the
problem definition may need to be adjusted.
End-Product consideration
This task will define which end-product/design will be the best solution to the
problem defined in the project definition.
Technology consideration
Different technologies will be researched before implementing the end-
product/design.
21
End-Product Design
Thorough documentation that includes a design process, identifies requirements
and detailed schematics.
End-Product Implementation
This task will implement the end-product using the identified technology.
End-Product Testing
This task will test the end-product for proper operation, and ensure that testing
results are accurate.
End Product Documentation
This task will create documentation that includes all of the testing that occurred
on the system and documentation explaining the operation of the system.
End Product Demonstration
This task will demonstrate the project for the advisors and industrial review panel.
The industrial review panel demonstration is a deliverable for the project and
must be accomplished on time.
End Project Reporting
This task includes all reporting done during the life of the project. Weekly emails,

4.1.3 Estimated Financial Requirements
The financial requirements for testing and implementation are dependent upon
the technology considerations and the end product design that is chosen. These
resources will be included in the design documentation after the end product
decision has been made.

4.2 Project Schedules
This section contains the project schedule and the schedule of deliverables.
Both are represented by Gantt charts.
The project schedule begins with defining the problem and determining the
desired end product through research and comparison. Throughout this process,
available technologies will be considered and the appropriate technology shall be
selected for use in the design of the end product. This process will be followed
by the end-product design and implementation process. Testing will follow the
implementation, depending of the end-product design and the funding available.
End product documentation will be developed and the end product will be
demonstrated to the advising faculty, and again for industrial review panel. The
project will conclude with a final report stating the conclusions and outcome of
the project. Throughout this process weekly emails will be sent to all group
members and advisors to inform and track the progress of the project.
25
4.2.1 Project Schedule
The project schedule provides a timeline in which the project tasks and deliverables can be set to ensure the project is
completed on time. Comments on tasks that take time in both semesters are added to indicate that no work will be done
from May through August, for example, the weekly e-mails.

Section 5 – Closure Material
Contained within this section are the project team information and the conclusion.
5.1 Project Team Information
This section contains information about the client, faculty advisors, team
Because traffic accidents happen everyday it is important that a system be
developed to detect an accident and report it to a call center. The end product
will be able to decrease emergency vehicle response time and possibly save
someone's life.
