Project Meeting 2020.10.08

5b/6a Task 1 Project Management (milestone)

• Technical calls going well for everyone
• We discussed getting started on the 6a scope
  • Task 1: Project Management
    • Started
  • Task 2: Complete Estimation Mode
    • Getting Jeff Newman under contract and will invite him to the technical calls
    • Ok for @Newman to start on cdap estimation data bundle (EDB) larch integration
    • Once done with TVPB, Doyle to start on trip model estimation mode
    • The other task item, larch examples for other submodels, needs more discussion before getting started
      • Before we create 25 larch estimation notebooks, let's discuss if there's a better way to do this
      • Maybe a larch example for each of the four types of models as opposed to one for each submodel?
      • Maybe more automation and less notebook (since notebooks are good for education but not so good for automation)?
      • We'll discuss at an upcoming technical call
    • SEMCOG team created an EDB to Alogit writer
    • Add @Joel to the discussion as well
  • Task 3: Telecommute Model in Cooperation with SEMCOG
    • SEMCOG interested in essential/non-essential workers segmentation
    • Will use 2015 survey and potentially upcoming panel survey
    • Design needs to consider three things:
      • Empirical data / today's observed patterns from the survey, etc.
      • What-if, asserted, scenario analysis for COVID and other scenarios where we might have a calibration/target for telecommuting in mind
      • A design that works well for SEMCOG and its data and is also useful/configurable for other potential agency users
    • @Joel draft plan and then share memo at an upcoming technical call
  • Task 4: Transit Pass Ownership Model in Cooperation with SEMCOG
    • Not started
  • Task 5: Performance Enhancements
    • Let's consider making some performance enhancements if needed to help the TVPB and other related needs
    • Scaled integer skim storage could help TVPB. I talked with Doyle about this and we think it's a promising improvement
    • Let's add to the next technical call
  • Task 6: Prototype multiple models test system
    • Not started
  • Task 7: Input checking and error handling and pipeline improvements
    • Not started
  • Task 8: Maintenance and support
    • Started, and targeted to agency support, such as helping Clint with ARC, etc.
    • Not so much for random grad student questions
    • In general, we need to discuss how best to support folks beyond the PMC
    • Have them create an issue
    • How about a tiered system?
      • PMC tier 1
      • Tier 2 support (which requires some amount of payment)
      • Let's discuss at the next technical meeting

5b Task 2 Strategic Planning (milestone)

• Any comments on the updated version of the plan?
• I still need to add the optional test system paragraph and development roadmap

5b Task 10 Support for Three Zone Systems and TVPB (milestone)

• Jeff adding filtering of unavailable path segments so the systems doesn't waste time evaluating complete utilities for paths that are not possible
  • no maz to tap pairs > max distance
  • no tap to tap pairs with IVT == 0
  • no further away taps if they don't serve new lines
• Moving specification of constants out of TVPB and into yaml to save creation of lots of columns (i.e. memory)
• Jeff has Marin example just about running
