Everyday in a student’s life..
Works late in the night… Late night commute might be dangerous..
MIT saferide Provides a safe ride
Shuttletrack
Looking around our campus
New dorms coming near campus
•Campus safety issue
•More demand for saferides
Shuttletrack
ShuttleTrackShuttleTrack
MIT Students need a safe transit service
Why?Inclement weather and traffic causes delay
reliable
Solution:
GPS tracking of Saferides
Shuttletrack
Ideally, what people want is…

The BIG picture
Shuttletrack
Seems easy. Haven’t people already done it ?
http://directory.google.com/Top/Business/Industries/Telecommunications/Wireless/Location_Based_Services/Vehicle_Tracking/
Google lists over 100 companies* doing GPS fleet tracking. Why not borrow their idea and install on our vans?

Features:
• CDPD/cellular service
• Need commercial GIS software
• Generic nation-wide product
Too expensive
Maintenance is difficult
Not optimal for Saferide
Shuttletrack
Our approachAdvantages:
• Low cost
• Low maintenance
• Building on existing infrastructure
• EFFICIENT System-specific solution
• Sustainable in the longer run
• Can be promoted to other Universities
Shuttletrack
TIMELINE
• Develop and test hardware/software over Spring’02 and Summer ‘02
• GPS tracking of entire saferide fleet by end of 2002.
