  3. Topics • Introducing the transit model template (TMT) • Installing the TMT • Walking through the TMT • Calibrating the TMT • There will be a brief Q/A Session between topics 3

  4. Introducing the TMT 4

  5. What is the Transit Model Template? • A package consisting of: • A Cube-Voyager “application” • Application Guide • Development Guide • Two versions of the template • One for cities with modest transit services • Another for cities with more substantial services • The guides are applicable to both versions • The package is available for download at http://www.fsutmsonline.net/index.php?/transit_modeling/comments/new_fsutms_transit_modeling_framework

  6. The TMT Includes… • All scripts, executables, applications and sample files needed to install and set up the transit model • Application and development documentation • A built-in routine for calibrating the mode choice model • Several reports for transit model calibration and validation purposes 6

  7. Why Develop the TMT? • To provide a “ready to install” template fully consistent with the new statewide transit modeling standards • No readily-available tool for end users since the development of new statewide standards • Benefits • Streamlined transit model development efforts • Reduced documentation development • Reduced model development costs 7

  8. Who Can Use the TMT? • Anyone! • Some likely candidates… • MPOs looking to add a transit model to their existing highway-only model • MPOs with an existing transit model in Tranplan • MPOs with an existing transit model not consistent with new statewide standards

  9. TMT Limitations • It is not calibrated and validated to any particular location; the template… • Is not intended to be “plug-and-run” software • Does not know anything about your modeling area • Does not automatically calibrate and validate to the travel behavior of the area • It does not replace the need… • To collect transit data • To calibrate the mode choice model • To validate the transit model • It does not “improve” the existing model 9

  10. Transit Model Application Guide • Chapter 1: Instructions for importing the transit model into a travel demand model • Chapter 2: Descriptions of the model procedure • Chapter 3: Descriptions of the catalog key, input files and output files of the transit model • Chapter 4: Descriptions of the scripts that must be modified by the user to customize the transit model application to fit the model at hand • This document can be used as a reference in the Technical Report 3 (Model Application Guidelines) prepared for FSUTMS models

  11. Transit Model Development Guide • Chapter 1: Describes the elements of the transit network, including the transit lines, modes, operators, fares, speeds, and access connectors • Chapter 2: Describes the transit paths • Chapter 3: Reviews at the mode choice model used and explains the structure and utility equations • Chapter 4: Summarizes the transit assignment process and the transit assignment reports • This document can be used as a reference in the Technical Report 1 (Data Development)

  14. New Transit Model Standards • Standards originally developed in 1980s for original FSUTMS system were updated in 2006 for FSUTMS-Voyager System • The following documents discusses the standards, guidelines, parameters and settings • FSUTMS-Cube Transit Model – Application Framework, FDOT, May 2007 • FSUTMS-Cube Transit Model – Theoretical Framework, FDOT, May 2007 • FSUTMS New Standards and Enhancements – A user oriented approach, FDOT, January 2006 • Transit Modeling FAQs, FSUTMS Online website All documents are available at www.fsutmsonline.net 14

  15. Transit Model Framework • The transit modeling guidance alters depending on the amount of the transit service: • Tier A guidance for areas with “modest” transit service and modeling needs • Tier B/C guidance for areas with “intermediate” transit service and modeling needs • Tier D guidance for area with “substantial” transit service and modeling needs • Information about the modeling framework is available on FSUTMS Online at: http://www.fsutmsonline.net/index.php?/transit_modeling/comments/new_fsutms_transit_modeling_framework/ 15

  16. Questions?

  17. Installing the TMT 17

  18. Steps to Install the TMT • Step 1: Create a copy of the TMT in the existing highway-only model • Step 2: Link all the output files from the highway model required as input by the transit model template (see next slide for screenshot) • Step 3: Make necessary changes to the script and catalog keys in the model in order to customize it for the modeling area • Step 4: Install the AUTOCON program (refer to readme.txt file in the model folder) Detailed step-by-step procedure is described in the Application Guide to the Transit Model Template 18

  19. Link TM’s Input and Output Files These files are outputs of the transit model and the are input to the final highway assignment These files are outputs of the highway model and they should be linked to the right input boxes Input Files to the Transit Model Output Files of the Transit Model 19

  20. Key Input Files • Highway networks (Unloaded and Preassigned networks) • Highway skims (free flow and congested skims) • Person trip table by purpose • Production trip rate file (GRATES) and dwelling unit weights file (DUWEIGHTS) • Zonal data file • Transit line file/system data file/fares file/percent walk file • Transit coefficients file/mode choice constant/mode choice targets 20

  21. Key Output Files • Highway vehicle trip table for the final highway assignment • Person trip tables • Transit assignment summary reports • Station activity report 21

  22. Required Changes to the Scripts • Default transit speeds are set to the auto speeds on the streets on which the buses run • User should apply necessary logic to define and calibrate the transit speeds • Any new transit mode other than already defined in the system data file will require changes to PT scripts where TRANTIME[xx] for xx mode are defined Please see the Application Guide to the Transit Model Template for details 22

  23. Customizing the Template for Your Area • Step 1: Review the default values of the catalog keys used in the model • Step 2: Review the input files and customize it for the modeling area • Step 3: Make necessary changes to the scripts so that it corresponds to the transit service in the modeling area • Step 4: Calibrate the auto and transit speeds • Step 5: Calibrate the mode choice model • Step 6: Validate the base year transit assignments • Step 7: Test the model for at least one future alternative to assess its forecasting ability 23

  40. Questions?

  41. Walking Through the TMT Files and Networks representing the transit system Transit access, transit paths and mode choice Transit assignment 41

  42. Important PT Input Files (1) • System Data File • “TSYSD.PTS” file in the parameters folder • Defines modes, operators and wait curves • Transit Fares File • “TFARES.FAR” in the parameters folder • Defines the fare structure of the transit system • Factors Files • These files are automatically generated within the model • Defines weights for various travel components (e.g. fares, wait times, transfer time, walk time etc.) All PT steps use these files 42

  43. Important PT Input Files (2) • Transit Line File • Should be coded in PT line format • Public time table is used for coding the individual routes of the transit system • Reflects the best possible representation of the route alignment, stop locations and the frequency • Peak and off-peak services are represented separately All PT steps use this file 43

  44. Transit Speeds • There are no predetermined ways of representing transit speeds in the transit model • MxxTIMEAM, MxxTIMEMD fields added to transportation network representing travel time on the links for each mode xx • Link time can be refined for individual routes using LINE keywords (e.g., TIMEFAC, DELAY, DWELL etc…) 44

  45. Transit Data in the Transportation Network • The following transit-related data should be included in the highway network • Transit-only links • Station and park-ride micro-coding • Station data information 45

  46. Walking Through the TMT Files and Networks representing the transit system Transit access, transit paths and mode choice Transit assignment 46

  47. Transit Access • Transit access is connecting the zones (or centroids) to the transit network and vice-versa • How is transit access represented? In two ways: • Connectors from centroids to transit stops • For walk-access, estimates of transit accessibility for each zone • The representation of transit access performs a function similar to that of centroid connectors in highway path-building and assignment 47

  48. Three Types of Access • Walk-access • Walking between the zone (centroid) and the transit network • Requires that a transit stop is nearby • Auto-access • Driving between the zone (centroid) and the transit network • Assumes some type of parking is available near the first boarded transit service • Transfer/sidewalks • A short walk between the one transit service to the subsequent transit service 48

  49. Transit Path-Building • Determines best transit option for each I-J pair based on the cost of the trip • The number of transit paths is controlled by the mode choice structure • Example: ‘walk-transit’ & ‘drive-transit’ for peak and off-peak periods 49

  50. Transit Skims • Transit skims are the actual/perceived values of some of the cost components of a transit path for each I-J pair • These skims are used in the mode choice to calculate the ‘utility’ of the transit options 50
