OUTLINE OF PRESENTATION Problems encountered and Our
focus Flow chart and Overview Real time tracking of tum-tums Central server User-access Comparison and Conclusion
PROBLEMS ENCOUNTERED From the contextual enquiries, we had
made the following observations Information about tum-tums not available
readily No idea when a tum-tum is going to come,
what route is it going to follow Can get info from the tum-tum office, but no
runtime information (i.e when a tum-tum is actually needed)
OUR FOCUS We plan on designing a centralized
information system System for real time tracking of tum-
tumsGPS; RF-ID
Centralized server to store informationExternal or Gymkhana server
User-end system to access informationSMS, Web, Mobile app
OUTLINE OF PRESENTATION Problems encountered and Our focus Basic design and Flow chart Real time tracking of tum-tums Central server User-access Comparison and Conclusion
BASIC DESIGN Tracking of tum-tums at bus stops. Information to be transmitted to server Server keeps track of all buses running
at a time User can query the server for tum-tums
nearby their locations Server optimizes results as per user’s
start and end destination.

REAL TIMETRACKING OF TUM-TUMS We plan to track tum-tums Naïve way:
Tum-tum timetable can be created Start time, Expected end time Start location, End location
Estimation of time taken from one stop to another During peak hours During normal hours Night hours
This information can be used to predict the approximate position of the tum-tums
REAL TIMETRACKING OF TUM-TUMS (2) Near Field communication:
A RFID tag to be placed in every tum-tum with a specific identifier.
RFID scanners to be placed at every bus stop
Any bus crossing the stop is detected at the stop and is recognised using the identifier
The data has to be transmit to the central server.
Can be achieved by sending an automated SMS via GSM Currently used in some Air conditioners
REAL TIMETRACKING OF TUM-TUMS (3) Global Positioning System:
A GPS tracking device can be placed in every tum-tum.
GPS determines the current location of a tum-tum using GPS satelites
The recorded location is transmitted to a central server using a cellular (GPRS or SMS), radio, or satellite modem embedded in the unit

CENTRAL SERVER Keeps track of all the buses.
GPSRFID information
Maintains information of the following:Bus routesBus stopsEstimated transit time between stops.Start time of bus when it leaves its
stationay place.
CENTRAL SERVER (2) Whenever a query of type ‘<stop1
stop2>’ is sent to itScans the database to determine buses
currently near location1 Selects those buses which will go towards
location 2 Calculates the approximate time required
for the next two tum-tums to arrive at location 1
Responds to the sender with the information <Bus route, ETA>; <Bus route, ETA>
CENTRAL SERVER (3) Suppose a query of type ‘<stop1>
buses’ is sentScans the database to find the tum-tums
about to cross the bus-stopResponds to the user with information about
next 2 tum-tums <Bus-route, ETA>; <Bus-route, ETA>
OUTLINE OF PRESENTATION Problems encountered and Our focus Flow chart and Overview Real time tracking of tum-tums Central server User-access Comparison and Conclusion
USER-ACCESS A user generally wants to know
Buses from one bus-stop to other Buses crossing a given bus-stop
A user can make use of the information via the following methods :
Short Messaging Service A user can send an SMS in either of these formats
between <stop1> <stop2> crossing <stop>
An additional parameter <time> can also be allowed to find tum-tums at a specified time
The server responds with info about the next 2 tum-tums corresponding to the query
USER-ACCESS (2) Web Interface
Provide a web based portal to access information about the tum-tums
Real Time tracking on a Map can also be implemented RailRadar
Mobile ApplicationDevelop an app which can support the web
based functions

COMPARISON
NFC Tracking GPS Tracking
Cheaper than GPS Reader is around
Rs.1500/- ; tags cost around Rs.45/- each*
Less reliable Vulnerable to rain Bare-bones,
communication to the server has to be implemented additionally
Expensive Approx Rs. 10,000 for
each device More reliable;
accurate positioning Placed inside the tum-
tum; rain issues minimal
Communication features are embedded with most tracking devices
