Everyday in a student’s life. . Works late in the night… MIT saferide Late night commute might be dangerous. . Provides a safe ride Shuttletrack

Looking around our campus • Campus safety issue • More demand for saferides New dorms coming near campus Shuttletrack

Shuttle. Track reliable MIT Students need a safe transit service Why? Inclement weather and traffic causes delay Solution: GPS tracking of Saferides Shuttletrack

Ideally, what people want is… Shuttletrack

The BIG picture Shuttletrack MIT COMMUNITY MIT SAFERIDE VANS Shuttletrack

Seems easy. Haven’t people already done it ? Google lists over 100 companies* doing GPS fleet tracking. Why not borrow their idea and install on our vans? Features: • CDPD/cellular service Too expensive • Need commercial GIS software Maintenance is difficult • Generic nation-wide product Not optimal for Saferide *http: //directory. google. com/Top/Business/Industries/Telecommunications/Wireless/Location_Based_Services/Vehicle_Tracking/ Shuttletrack

Our approach Advantages: • Low cost • Low maintenance • Building on existing infrastructure • Sustainable in the longer run • Can be promoted to other Universities • EFFICIENT Systemspecific solution Shuttletrack

TIMELINE • Develop and test hardware/software over Spring’ 02 and Summer ‘ 02 • GPS tracking of entire saferide fleet by end of 2002. Shuttletrack
