Fairfax County Transit System
 FAIRFAX
CONNECTOR bus system.
 54 static bus routes
 xxx bus stops
 Other
bus systems also serve Fairfax
County
4
Transit Pilot Project



Three FAIRFAX CONNECTOR routes:
103, 105, and 108
Routes are complex
Have overlap
5
Transit 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
6
Transit Pilot Project - Data
Existing Data Sources:








Street Centerline Network
Stop Database (Paradox)
Boarding and Alighting
Data
Ridership Data
Census Block Groups
Planimetric Data
Public Facilities
Digital Ortho Photography
Pilot Data:




Created bus route layer
created using Dynamic
Segmentation
Geocoded Bus stops using
ArcView
Collected stop locations
using GPS.
Related stops to routes
using ADDROUTEMEASURE
7
Transit Pilot Project - Software
 ARC
INFO
Create bus routes using Dynamic Segmentation
 ARCVIEW
Develop desktop applications
 Map
Objects
Design Internet information query tools
8
Pilot Project - Bus Route Creation
 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

Transit Pilot Project - Applications
Planning
- Transit Shed
Marketing
- Mapping Bus
Operations
Routes
- Internet Data
Viewing
- Route Performance
- Internet Bus Trip
Comparison
- Optimal Bus Routes Planning
- Map Origins of “Park
& Ride”
Analysis
- Boarding and Alighting
Activity Analysis
- Determine Route
Miles
- Measure Distance
between Stops
10
Transit Pilot Project - Planning
Types of Applications:

Analyze land use and demographic features
within the service area
Compare route performance

Determine optimal bus routes


Transit Pilot Project - Planning
13
Transit Pilot Project - Planning
Benefits:
 User
friendly tools for planning tasks
 Scenario analysis for new service design,
routing adjustment, etc
Power
 Baseline
 Easily
study of the service area
applicable for traffic & planning studies
14
Transit Pilot Project - Marketing
Types of Applications:
 Mapping
bus routes
 Internet
data query
 Internet
bus trip planning
 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:
 Reduce
the number of phone calls to the
information center
 Efficient / accurate field data collection and
maintenance
 Reduce
staff time for mapping applications
17
Transit Pilot Project - System
Implementation 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
