Shuttletrack 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 ShuttleTrack 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…

Shuttletrack MIT SAFERIDE VANS MIT COMMUNITY The BIG picture

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 Need commercial GIS software Generic nation-wide product Too expensive Maintenance is difficult Not optimal for Saferide

Shuttletrack Our approach Advantages: 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.
