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
Installing the Transit Model Application • Import the transit model into the travel demand model • Review the modules with the transit model • Connect input and output files from the model to the files in the transit model • Modify the catalog keys, appropriate scripts and input files • For the base year, calibrate the auto and transit speeds (or travel times) and compare them against observed data • Calibrate the mode choice model for the base year • Validated the base year transit assignments by comparing them to observed counts • Test the transit model against at least one future alternative to assess its forecasting ability
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
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
Transit Prep Step • Default speeds set to auto speeds. Speed curves need to be defined and applied in these steps The default mode numbers used in the model are 21-27. If additional modes are defined, 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
Mode Choice Model Step Default ZDATA file variables are used in this step and may need to be changed By default, only one set of trip generation rates is used. If the model area consists of regions with different trip generation rates, they can be accommodated in this step to calculate auto ownership percentage by TAZ
