    Earlier FSUTMS/Tranplan Versions: 1 & 2
    TCRPM 3 – Highway-only model
    developed and calibrated completely in
    TransCAD … thought we were done!
    Model development switched to Cube
    Voyager after Model Task Force action in
    the fall of 2004.

  2000 Treasure Coast Regional
    Planning Model (TCRPM)
    Cube Voyager based model

    Covers three counties
        Indian River
        St. Lucie
        Martin
    Two Flavors
        Highway – Only
        With Transit

                     TCRPM
    Uses FSUTMS Facility and Area type
    coding
    Trip generation rates are county specific
    Mode choice model
     Splits auto and transit trips

     Further splits auto trips in occupancy levels


    Run time for the full model is 7 min. on a
    3.4 GHZ machine
    Traffic Analysis Zones = 731

                    FTA Reactions to PT
    Strongly recommended micro-coding fixed-guideway,
    park-and-ride & kiss-and-ride stations to better represent
    transfer time
        Existing FSUTMS standards utilize same node for rail & bus
         stations
    Confirmed that multi-path builder is not compatible with
    existing FSUTMS mode choice structure
    PT v4.0 can not provide the necessary information for
    New Starts quality control tests
    Trying to quantify impacts of multi-path systems on
    New/Small Starts; would prefer single-path but do not
    require it
    Helpful to have empirical evidence of typical New/Small
    Start situations in PT

  FDOT Central Office Research
    Citilabs added a best-path switch in PT
        Addresses FTA’s New Starts quality control tests
        Mimics single-path path-builders
    Developed and tested 3 prototype models
        (1)PT multi-path (2)PT best-path (3)PT-TRNBUILD
         hybrid
        Purposes:
              Provide empirical data to assist with FTA/Citilabs discussions
              Help determine best design for PT model that produces
              explainable results that are sufficient for New/Small Starts
              analysis
              Identify any issues as early as possible
        Developed modeling standards (“frameworks”) for
         multi-path system, adjusted slightly for other 2
         systems

                SERPM 6 - TRNBUILD
  Could not wait for PT “best path”
  Single-path builder from TP+ & available in Voyager
  Link-based, some similarities to Tranplan’s path-
  builder
  Well-known to FTA
      Reliable history that dates back to MINUTP
  Used nationwide
      Atlanta, Washington DC, Columbus OH, Northern NJ
  Can read Voyager highway networks directly
  Easy to convert PT network & connectors
  Only being used in Florida for SERPM6
  Future development not supported by Citilabs
