Project Meeting 2021.12.02

Agenda

• Update on the visualizer development
  • Model summaries are created in output folder and simwrapper reads the summaries to create plots
  • SimWrapper can be installed via pip
  • To create dashboard, add the "summarize" step at the end of the model list in settings.yaml
  • Summary csvs are created using python expressions in summarize.csv
    • These expressions have access to all of the data in an activitysim run including skims
  • Segmentations by demographic group, e.g. income, are under development
  • The local machine creating the dashboard acts as a file server is created to run the dashboard on the web as a background process.
    • Hosting on the cloud should be no problem
  • Request for "best practice" recommendations to handle creation and sharing (internally and externally) of dashboards
    • Berlin has a dedicated server that holds all model runs and acts as the dashboard server
  • Request to add more description text options for plots
  • Request for comparison between scenarios
  • Previous request for filtering / brushing is currently under development
  • Recent infrastructure bill mentions Travel Demand Data and Modeling, including web-based evaluation tools (section 11205)
  • Some more testing is still needed
  • Goal is to wrap up phase 1 development by the end of the year
• Vehicle type model development
  • Model has been added to mtc example
  • New model, vehicle_choice, was created and a new "canonical table" called vehicles was added
  • There is one single vehicle_choice.yaml, and to change between option 2 or option 4, the user would change the spec and coefficient csv options to the one they want in the vehicle_choice.yaml
  • Would like some automated code to create the spec file
  • Need to confirm that model specification has been finalized
  • Combinatorial effects are treated dynamically in the CDAP model, could we take that implementation to improve the vehicle type model?
  • Will consider alternative options to make specification more extensible before giving go-ahead for code review
  • Suggest using model option 4 for model calibration and validation
  • How will regional differences be implemented and are they important?
  • Propose renaming of model to vehicle_type_choice
• RFP has been released
