Project Meeting 2020.08.13

Task 1 Project Management (milestone)

• Additional estimation integration improvements in PR #328 based on feedback from SEMCOG, SFCTA, and Jeff Newman
• Estimation mode works with existing destination choice sampling features. Maybe we should improve our examples and/or add more functionality to our existing sampling routines?
• As we continue to work on estimation mode, make sure the integration with larch avoids duplication
  • Joe: Goal is that model specification coding occurs in one place only (ActivitySim) whether for application or to generate estimation files. We want to avoid any potential for inconsistency between estimation and application

Task 2 Strategic Planning (milestone)

• Working through comments on the draft strategic development and contribution plan
• Multiple regional models test system
  • I'm going to add some additional discussion about it being a framework (in addition to a stream of submodels) based on discussion Joe and I had related to just running TM2 tour mode choice example; for example, ideas around a data contract/registry for each submodel
  • Joe suggests we list out use cases for types of regional revisions - just changing coefficients, changing modes/alternatives, adding new submodels, revising the order/sequence of submodels - and how we might manage this
  • Alex is concerned that having each agency partner update/maintain their model is unsustainable and that we need to focus on version management by the partners
  • Stefan thinks the additional assurances for upgrading to new versions would be helpful
  • I think we need to separate explicit examples for each region from the need for more generic / modular examples to test all functionality
  • We need to over time increase submodel modularity
  • @Joe to setup a call next week to discuss in more detail since this is a complex topic to sort out in short meetings
  • @Partners to think about how much customization they need as we move forward
• We're planning to discuss August 20th

Task 10 Support for Three Zone Systems and TVPB (milestone)

• Revised TM2 test example
• @Lisa working on data prep; I'm working on expression revisions
• Jeff and I discussed more easily running just tour mode choice and potential improvements like exposing creation of tour and trip tables like initialize_households and initialize_landuse (e.g. initialize_tours and initialize_trips). Let's see what makes sense as we work on this example.
• @Jeff working on TVPB code
