    The Transit Model Application

     “Ready to go” FSUTMS-Voyager application of the Transit
     Model that includes all of the model elements in the
     framework
      • Speeds *          Connectors      Pathbuilding
      • Mode Choice       Assignment     Reporting
      • Mode Choice Calibration *        Summit data files

     Avoids scripting framework elements, allowing the user to
     focus on localized attributes such as transit speeds and mode
     choice calibration

     Tier A, B and C areas (covers all areas except for SERPM)

     Released September 2008
              * - requires scripting/information from user
1
    Installing the Transit Model Application

    1.   Import the transit model into the travel demand model

    2.   Review the modules with the transit model

    3.   Connect input and output files from the model to the files in the transit model

    4.   Modify the catalog keys, appropriate scripts and input files

    5.   For the base year, calibrate the auto and transit speeds (or travel times) and
         compare them against observed data

    6.   Calibrate the mode choice model for the base year

    7.   Validated the base year transit assignments by comparing them to observed
         counts

    8.   Test the transit model against at least one future alternative to assess its
         forecasting ability




2
    Importing the Transit Model Application

     Download the model from FSUTMSOnline

     Open the transit model application in CUBE Voyager

     Create new directory and save it in the applications folder of the
     model




     Close the application

3
    Importing the Transit Model Application
    (Contd.)

     Open the model into which transit model application
     needs to be imported

     Insert the transit model application group




     Change the execution order of the transit model step so
     that it is run after the trip distribution step

    Default speeds set to auto     The default mode numbers
    speeds. Speed curves need      used in the model are 21-27. If
    to be defined and applied in   additional modes are defined,
    these steps                    transit travel times must be
                                   added for those modes in
                                   these steps

    Transit Paths Step
                         If additional modes are defined,
                         transit travel times for those
                         modes must be added for
                         pathbuilding and transit skim
                         calculations in these steps
