5. Shuttletrack Issues closer to our campus… Mattapan man shot near campus Apr 9 -------------------------- New dorms coming near campus --------------------------

6. Shuttletrack In Summary… MITStudents need a safe transit service Why? Inclement weather and traffic causes delay reliable Solution: GPS tracking of Saferides

7. Shuttletrack Ideally, what people want is…

8. Shuttletrack MIT SAFERIDE VANS MIT COMMUNITY The BIG picture

9. 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

10. Shuttletrack Our approach Advantages: 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.
