In Summary…In Summary…
MITStudents need a safe transit service
Why?Inclement weather and traffic causes delay
reliable
Solution:
GPS tracking of Saferides
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
• System-specific solution
• Sustainable in the longer run
• Can be promoted to other Universities
TIMELINE
• One van by end of Spring 2002
• Entire saferide fleet by end of 2002.

Summary and status report
• Radio hardware is currently being assembled
• Web development is underway in collaboration with ENVIT
Shuttletrack
Step 1: Establish Modem Communication
• Configure modem – Determine communication protocol to use – Send and decode messages (e.g. “HELLO”, send
modem ID, packet number, check sum)

Step 2: Send GPS data
• Configure GPS – modem connection– Initialize settings for GPS box using Kantronics
box– Kantronics box parses NMEA string and saves in
memory– Kantronics box packetizes GPS data and sends it.
