Project Meeting 2021.03.18 - ActivitySim/activitysim GitHub Wiki

Task 1 Project Management (milestone)

  • Updated bench contract coming soon
  • Partners only chat after this call
  • Merged develop2 to develop and need to work on documentation/user guide
  • Continued SANDAG performance testing discussion
    • Its really good the 3 zone system code is working for a full population run at SANDAG
    • But runtimes are too slow
    • Now running 22 hours, including 16 hours for destination choice models
    • The destination choice models can be faster and this is good for everyone
    • Why are they slower than the existing model?
    • Its good for the project to keep populating the multiregion timing sheet by submodel to identify performance issues and then make improvements
    • RSG also added de-duplication for the TVPB to the accessibility calculator so this will help with SANDAG runtimes
    • SANDAG trip purpose and destination failure rate is low so that's not the issue
    • We can investigate and fix the slow trip destination performance with the MTC example too
    • SANDAG will engage RSG separately to help understand performance issues and so this may pull Jeff away for a bit, but that's ok since performance tuning is important to everyone
  • Each phase of work should have an administration TO, performance TO, and maintenance TO, plus whatever else is desired
  • We should think about designing a better accessibility calculator - i.e. the disaggregate accessibility calculator discussed during the last round of scoping

Task 2 Complete Estimation Mode (milestone)

  • Newman nearing completion of all examples and code updates

Task 3 Telecommute Model in Cooperation with SEMCOG (milestone)

  • Need to merge to develop and finish todos from last call

Task 4 Transit Pass Ownership Model in Cooperation with SEMCOG (milestone)

  • Need to finish todos from last call

Task 5 Performance Enhancements (milestone)

  • Code merged and validated; need to work on documentation

Task 6 Prototype multiple models test system (milestone)

  • Plan updated for discussion
  • SANDAG to add example for future testing like the others being built, see examples

Task 7 Input checking and error handling and pipeline improvements (milestone)

  • Let's now start and discuss/pick some specific todos, possible from the task scope
  • I'd also like to discuss pain points with users
  • We'll also review Jeff's change logs for the agency examples for ideas, see arc, psrc, semcog
  • I'll build a list of items for discussion next time
  • Let's agendize 30 minutes of a technical call for this brainstorming topic
  • Would be good to talk with Gregor at SANDAG and also work on the settings file inheritance stuff since it can be confusing

Task 8 Maintenance and Support (milestone)

  • Continuing to help PSRC and SANDAG with their testing and fitting in improvements as we can
