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.
