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
