Transit Path-Builders

• Two types single-path multi-path
• Single-path
• Exclusively available in Tranplan, Minutp TP
• Dominant path-builder in Florida US
• Multi-path
• Available in TransCAD Cube-Voyager (PT)
• Becoming more prevalent

Multi-Path vs. Single-Path
Rail/Shuttle
Local Bus
O
D
Express Bus
Path Weighted Time Single-Path Skim Values Multi-Path Skim Values
Rail/Shuttle 55 min 100 45
Local Bus 90 min -- 20
Express Bus 65 min -- 35

Recommended Strategy

• Short-term (next 2-5 years)
• Using PT best-path
• Two levels of modeling guidelines
• General for everyday modeling (e.g., LRTPs)
• New/Small Starts for specialized studies (e.g.,
  FTA-related AAs)
• Long-term
• Migrate to PT multi-path model design
• Between short- long-term
• Coordinate with Citilabs FTA to test new
  versions of PT discuss New Starts issues

5
Status / Next Steps

• Developed framework documents to summarize key
  points
• Theoretical coordination of individual parts
• Application parameter settings, technical
  details
• Both available on www.fsutmsonline.net
• FDOT gathering feedback
• Will continue to finalize details procedures
• Need for more speed/delay studies and local
  transit on-board studies
• Transit model training workshop June 4-7, 2007

Guidelines Tiers
Tier Transit Service Data Availability Examples
A Local service only no park-and-rides System-wide boardings transfer rates Polk County, SunTran
B Local express service some park-and-rides System-wide boardings transfer rates May have recent on-board survey Votran, Spacecoast
C Local express service some park-and-rides Recent on-board survey system-wide boardings transfer rates Jacksonville, Orlando, Tampa
D Many different types of service extensive park-and-ride system potential major fixed-guideway system Recent on-board survey for all modes detailed boarding transfer rate information Southeast Florida

Transit Access
Type New Guideline
Zonal Use single ½ mile can/cannot walk buffer Compute percent walks in GIS, CUBE 4.2/5.0
Walk 2 types of connectors zone-stop, zone-station Use PT to develop connectors Use program to coordinate percent walks connectors
Drive Use revised AUTOCON to develop connectors
Sidewalk/ Transfer 3 types of connectors stop-rail platform, rail platform-stop, stop-stop in CBD areas Use PT to develop connectors
8
Network/System Coding

• New system data fare files
• Maintain all transit lines in single file
• Take advantage of advanced coding features
• Code these elements in transportation network
• Transit-only links
• Micro-code fixed-guideway stations
• PNR/Station data
• Use new mode definitions

9
Path-Building/Mode Choice (1 of 3)

• Tier A Areas
• Local service only
• No park-and-rides
• Limited data available
• Build walk-transit drive-transit paths per
  period
• Paths include all modes

10
Path-Building/Mode Choice (2 of 3)

• Tier B/C Areas
• Local express service
• At least some park-and-rides
• At least system-wide boardings, but on-board
  survey likely
• May be planning for New/Small Start project in
  near future
• Build 4 paths per period
• Walk-bus
• Walk-project/premium
• Auto-bus
• Auto-project/premium

11
Path-Building/Mode Choice (3 of 3)

• SERPM (Tier D Areas)
• Many types of service
• Extensive park-and-ride system
• Detailed boarding rider data available
• Can be planning for New/Small Start project in
  near future
• Build 8 paths per period
• Walk-bus
• Walk-project/premium
• Walk-MetroRail
• Walk-TriRail
• Auto-bus
• Auto-project/premium
• Auto-MetroRail
• Auto-TriRail

12
Mode Choice Calibration Transit Validation

• Mode choice calibration
• Use new coefficients
• Script mode choice model where sensible
• Transit validation steps
• Review trip distribution
• Calibrate bus travel times end-to-end
• Calibrate mode choice model
• Validate boardings by mode and/or operator
• 20 within each category

- New/Small Starts projects only
13
Highway Modeling Impacts

• Standard highway model practice has strong
  impacts on transit modeling
• SPDCAP table adjustments
• Distribution corrections (e.g., k-factors, etc.)
• 0-car household impedances
• New transit model stresses need for
• Refraining from strong SPDCAP table modifications
• Validating trip distribution
• Also
• Code transit-only links transit station data on
  highway network
• Stability of highway-assignment results

14
Outstanding Issues

• Updating auto-bus speed relationships
• Develop procedures/programs
• Walk- drive-access connector programs
• Transit assignment reporting program
• Path-building script templates
• Some issues will require coordination with
  Citilabs
