GTAModel V4.0.2 Input Directory

Tip

In GTAModel V4.0.2 input data is organized into the Scenario folders with the following structure, Scenario-Directory/RunYear/ScenarioName. The scenario names are not required to be the same between the different scenario folders.

Activity Distributions

This directory contains the information on how to generate activity episodes. Between runs these files should not change unless it has been recalibrated.

Base Year Matrix

Files contained in this directory are used for estimation and validation purposes.

The folder AccessStationInitialCapacities contains a CSV vector for each time period with the ratio of the number of parking spots for each station that are occupied.

Estimation

This directory contains the parameters used to estimate the different models contained within GTAModel.

Estimation Result

This directory contains the results of the estimation process for GTAModel V4.
The mode choice algorithm's parameters are read in from this directory.
For re-calibration you can edit the mode choice's values, please contact TMG before doing this though for guidance.

Note

In GTAModel V4.0 the mode choice estimation results are used in order to setup the parameters for the run. Starting in GTAModel V4.1 the parameters are directly integrated into the model system.

Scenario-Employment

  • EmpOccRates: A folder containing a CSV file for each employment category rate of jobs belonging to the category.
  • ExternalRates: A folder containing a CSV file for each employment category with the rate of jobs belonging to external workers.
  • WaHRates: A folder containing a CSV file for each employment category with the rate of jobs belonging to workers who work from home.
  • TotalEmploymentByZone.csv: This file contains a CSV mapping each zone to the total employment contained within.
Note

All rates in the default GTAModel V4.0.2 are computed at the planning district level. Some versions of the model have changed this to work at the zonal level.

Scenario-Network

Each year contains a file called BaseNetwork.nwp containing the master network. Each scenario then contains a set of files that are used for generating the time period networks. More information can be found here describing their format.

Scenario-Population

  • HouseholdData:
    • Households.csv:
    • Persons.csv:
  • WorkerCategories: For each occupation and employment category a CSV file is exists containing with three columns: Zone, WorkerCategory, and the ratio of that worker category for the given zone.
  • ZonalResidence: For each occupation and employment category a CSV exists containing two columns: Zone, and the number of workers in that zone that work within the GTHA and the number of non-roaming workers of that category living in that zone.
  • ZoneData:
    • Zones.csv: Contains information related to each zone in the zone system. A detailed description of the format can be found here.
    • Zones.zfc: A binary cached version of the Zones.csv. Starting in XTMF1.5 this file is no longer created during the model run.
    • Regions.csv: A CSV file with two columns: (Zone, Region). Each zone can only belong to a single region. External zones should be absent or given a region number of 0.

Scenario-Stations

  • StationCapacity.csv: A CSV file with the columns in the order of Zone and Capacity for each station zone.

Scenario-Transit Fares

  • Fare Rules.xml: An XML file in the fare schema format describing the fare policies when initially boarding or transferring between transit agencies.
  • York_Region_Zone: A folder containing a shapefile that shows the different fare zones for York Region.

School

  • BaseYearStudentLinkages-Elementry.csv: A square CSV matrix of home zone to school zone linkages from TTS for the elementary school aged students.
  • BaseYearStudentLinkages-Highschool.csv: A square CSV matrix of home zone to school zone linkages from TTS for the highschool aged students.
  • BaseYearStudentLinkages-PostSecondary.csv: A square CSV matrix of home zone to school zone linkages from TTS for the post secondary aged students.
  • ElementaryStudentsByZone2011.csv: A CSV vector containing the number of students from TTS by home zone.
  • HighschoolStudentsByZone2011.csv: A CSV vector containing the number of students from TTS by home zone.
  • UniversityStudentsByZone2011.csv: A CSV vector containing the number of students from TTS by home zone.

Validation

  • RoadCounts
    • Screenline Mapping 2.csv: This file contains a mapping of screenline names to the station numbers within TMG's base year network. This file is used in the model system.
    • Screenline Mapping.csv: This file contains the same mapping of screenline names to the station numbers with the addition of local screenline names and local station ids.
