Fairfax County Transit System u FAIRFAX CONNECTOR bus system. 2 54 static bus routes 2 xxx bus stops u Other bus systems also serve Fairfax County 4
Transit Pilot Project u u u Three FAIRFAX CONNECTOR routes: 103, 105, and 108 Routes are complex Have overlap 5
Transit Pilot Project - Objectives u Demonstrate GIS potential in transit planning, operations, and marketing u Effectively model Fairfax Connector bus routes and bus stops using GIS. u Develop custom desktop applications for planners u Integrate existing the transit data sources with GIS database 6
Transit Pilot Project - Data Existing Data Sources: u u u u Street Centerline Network Stop Database (Paradox) Boarding and Alighting Data Ridership Data Census Block Groups Planimetric Data Public Facilities Digital Ortho Photography Pilot Data: u u Created bus route layer created using Dynamic Segmentation Geocoded Bus stops using Arc. View Collected stop locations using GPS. Related stops to routes using ADDROUTEMEASURE 7
Transit Pilot Project - Software u ARC INFO Create bus routes using Dynamic Segmentation u ARCVIEW Develop desktop applications u Map Objects Design Internet information query tools 8
Pilot Project - Bus Route Creation u Created in Arc/Info u Used MAKEROUTE, SUBSELECT, APPEND, REMEASURE, etc. u Time consuming and difficult for routes with loops. u Errors difficult to fix without rebuilding route u Results were excellent 9
Transit Pilot Project - Applications Planning - Transit Shed Marketing - Mapping Bus Routes - Internet Data Analysis Viewing - Route Performance - Internet Bus Trip Comparison - Optimal Bus Routes Planning - Map Origins of “Park & Ride” Operations - Boarding and Alighting Activity Analysis - Determine Route Miles - Measure Distance between Stops 10
Transit Pilot Project - Planning Types of Applications: u Analyze land use and demographic features within the service area u Compare route performance u Determine optimal bus routes 11
Transit Planning - Arc. View 12
Transit Pilot Project - Planning 13
Transit Pilot Project - Planning Benefits: u User friendly tools for planning tasks u Scenario analysis for new service design, routing adjustment, etc Power u Baseline u Easily study of the service area applicable for traffic & planning studies 14
Transit Pilot Project - Marketing Types of Applications: u Mapping bus routes u Internet data query u Internet bus trip planning u Efficiently collect & store bus stop information 15
• Geocoded by Intersection, not the actual stop location. East and westbound stops in same spot. • Westbound Stop (GPS) • Eastbound Stop (GPS) • Stops not in intersections database, located with GPS 16
Transit Pilot Project - Marketing Benefits: u Reduce the number of phone calls to the information center u Efficient / accurate field data collection and maintenance u Reduce staff time for mapping applications 17
Transit Pilot Project - System Implementation and Future Plans u Develop all bus routes using PATH command in Arc/Info u Collect bus stops using GPS u Refine developed applications u Identify new applications u Transfer maintenance responsibility to each section in DOT u Develop Internet/Intranet Applications with Arc/IMS 18
Speaker - Immediate Plans u. Be on the first tee of the USF golf course by 5: 30 pm today. 19
