TransTools Model Data location

• Home of TransTools scenario data is configurable
  by user.
• Example C\TransToolsData
• ALL data which needs to be exchanged between
  models MUST be located here
• ALL data which users need to access SHOULD be
  located here
• Execution log files SHOULD be located here
• Programs MAY be located anywhere

TransTools Model Data directory structure 1

• Within Data location exist these primary
  directories for different categories of data
• \Matrices
• \Zones
• \Network
• \Logistics
• \Logs
• Within EACH of these directories exist one
  directory for EACH scenario. Examples
• \TestScenario
• \2000_00A
• \2020_00A
• \...
• We do not infer any meaning from names of
  scenarios
• Make sure to pick unique names for actual files
  within \logs\scenario\

TransTools Model Data directory structure 2

• Each scenario directory contains one or more MS
  Access databases. Example
• c\TransToolsData\Matrices\2000_00A\N2Matrices.mdb
  
• c\TransToolsData\Matrices\2000_00A\N3CostMatrices
  .mdb
• c\TransToolsData\Matrices\2000_00A\N3FreightRailC
  ostMatrix.mdb
• c\TransToolsData\Matrices\2000_00A\N3FreightRoadC
  ostMatrix.mdb
• c\TransToolsData\Matrices\2000_00A\N3Matrices.mdb
  
• This partitioning is done in order to stay within
  2GB limit of MS ACCESS
• Within each database are a number of tables. One
  for each dataset in the model. These tables have
  FIXED names
• Full Datamodel is available in html-documentation
  from Bo Grevy. Bo Grevy should be kept informed
  of any changes.

Use of ArcGIS and Model Builder in TransTools

• The execution of a TransTools model scenario in
  the proper order is carried out by an ArcGIS
  Model Builder model
• All such models (one for each scenario) are
  located within an ArcGIS toolbox file in the main
  Transtools data loaction, like
• C\TransToolsData\TransToolsScenarios.tbx

6
Creating a new scenario (subject to change)

• In EACH of the primary directories in the
  Transtools data location, copy an existing
  scenario and give it an appropriate name. Like
  this
• copy c\TT-data\matrices\2000_00A to
  c\TT-data\matrices\2020_00B
• Using ArcGIS Model Builder copy an existing
  model, rename it and set it to point to the new
  scenario-name
• Edit the data to implement changes in scenario
• Run the model
