With GIS:ran more than 40 computer scenarios in just 3 days
analyzed benefits of building a new station versus moving an existing one
determined best solution: relocate two existing stations

Results:reduced the time required to reach all locations in the city from 7 minutes to 4 minutes
over 5 years, the city saved an estimated $2M in building costs, equipment, salaries, etc.

Results:
in the 1994-95 school year:- more than 500 fewer buses were needed
statewide than originally estimated- 15,000,000 fewer miles were driven than
originally estimated
between 1990 & 1996:- the state saved over 2,000,000 gallons of fuel
