Project Meeting 2020.12.17 - ActivitySim/activitysim GitHub Wiki

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

  • Meet next Tuesday the 22nd but cancel the 24th and 31st
  • Still working on getting the multizone work released by end of year
  • BYU meeting went well
  • They also expressed interest in a simpler / more generic example model for typical MPOs
  • Using the new dynamic chunking feature should help their runtimes
  • Oregon DOT is a promising option to contribute the simpler / more generic example model to the consortium

5b Task 2 Strategic Planning (milestone)

  • Partners discussed and agreed its good for me to now review/address comments
  • The document will be a living doc, but we'll now wrap up this version as part of the contract deliverable
  • We need a better articulation of the "spines/products/templates" and the versions/releases, requirements for setup, etc.
  • And how this relates to help for developers as well as users/deployment
  • Which spine should I pick?
  • Let's better formalize the "spines" throughout the entire system

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

  • Debugged and corrected a few more expressions/configs related to drive transit so results looking better
  • Having the real full scale example is so helpful for verification of the code / example
  • There's certainly a balance between perfecting this example we're using for testing versus project resources
  • The code is working as expected
  • Would be good to version the validation results so its easier to see the changes with each iteration
  • Being able to debug/run just tour mode choice in 8 minutes and reload the cached TVPB utilities is super helpful

6a Task 2 Complete Estimation Mode (milestone)

  • stop_frequency updated and now working on trip_destination and trip_scheduling

6a Task 3 Telecommute Model in Cooperation with SEMCOG (milestone)

  • No update

6a Task 8 Maintenance and Support (milestone)

  • Providing a bit of support to Stefan as he works on getting the model running at PSRC
  • Working on some memory issues for his parcel/maz setup
  • We don't have a complete 40k maz TM2 activitysim test setup, but we are setting up the SANDAG cross border model, which uses 3 zones and TVPB and may require some improvements, which we will of course contribute
  • Stefan to keep working on it and RSG to support
  • Clint's efforts would be easier if we did a better job with backwards compatibility
  • We already updated the TM1 example to use the updated code that supports multi zone systems
  • Maybe we should think about versioning the expressions API?
  • Supporting multiple zone systems and estimation integration resulted in a lot of core code changes
  • Hopefully the code base will be more stable moving forward - i.e. post our push to version 1
  • Let's be more intentional about backwards compatibility
  • We'll hear more from Clint on Tuesday
