Fairfax County Transit SystemFairfax County Transit System
FAIRFAX CONNECTOR bus system. 54 static bus routes
xxx bus stops
Other bus systems also serve Fairfax County

Transit Pilot Project - ObjectivesTransit Pilot Project - Objectives
Demonstrate GIS potential in transit planning, operations, and marketing
Effectively model Fairfax Connector bus routes and bus stops using GIS.
Develop custom desktop applications for planners
Integrate existing the transit data sources with GIS database

Created in Arc/Info Used MAKEROUTE, SUBSELECT,
APPEND, REMEASURE, etc. Time consuming and difficult for routes with
loops. Errors difficult to fix without rebuilding route Results were excellent

•Westbound Stop (GPS)
•Eastbound Stop (GPS)
•Geocoded by Intersection, not the actual stop location. East and westbound stops in same spot.
•Stops not in intersections database, located with GPS

Benefits:Benefits:
Transit Pilot Project - MarketingTransit Pilot Project - Marketing
Reduce the number of phone calls to the information center
Efficient / accurate field data collection and maintenance
Reduce staff time for mapping applications

Transit Pilot Project - System Transit Pilot Project - System Implementation and Future PlansImplementation and Future Plans
Develop all bus routes using PATH command in Arc/Info
Collect bus stops using GPS Refine developed applications Identify new applications Transfer maintenance responsibility to
each section in DOT Develop Internet/Intranet Applications with
Arc/IMS
