Project Meeting 2021.03.11 - ActivitySim/activitysim GitHub Wiki

Task 1 Project Management (milestone)

  • Bench contract coming soon, thanks everyone for reviewing the task orders
  • Merging develop2 to develop is currently held up by the Travis tests not passing related to some file handling / setting file inheritance for the multiple tests
    • Jeff looking in to it and then I'll pull
    • Then Newman can merge in estimation updates too
  • SANDAG ran 3 zone example with a 100% sample and their land use and skims successfully
    • Run times are 30 hours, with 10 hours for accessibility
    • Wu update the multi-region timing worksheet for discussion next time about where we can look for additional optimizations
    • Asim is good code but needs to run faster. The current model runs in 12 hours.
    • Will test representative logsums improvement
    • PSRC accessibility model runs in 20 minutes but doesn't have TVPB

Task 2 Complete Estimation Mode (milestone)

  • Fixed mandatory tour scheduling issue so Newman can proceed
  • Newman continuing to work through implementations of examples

Task 3 Telecommute Model in Cooperation with SEMCOG (milestone)

  • Design page updated
  • Need to revise some more - merge in the additional considerations, add the sandag model design info from the pdf, add a discussion about the semcog specific implementation issues, and create an issue for discussing the What If feature

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

  • Design page updated
  • Need to revise some more - merge in the additional considerations, add a discussion about the semcog specific implementation issues, and create an issue for discussing the fare subsidy design issue
  • Can each person get a fare attribute? How does that relate to the skimmed fare? There's a lot of heterogeneity in how fares work throughout the country
  • Joel to review data shared by MTC

Task 5 Performance Enhancements (milestone)

  • Representative logsums implemented and tested with MTC and SEMCOG
  • I need to validate rep logsums results
  • PSRC testing pre-sampling improvements

Task 6 Prototype multiple models test system (milestone)

  • Plan updated, need to make a couple more updates and then please review
  • SANDAG to add example once they get the kinks worked out and we have formal directions for doing so

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

  • Let's soon start and discuss/pick some specific todos

Task 8 Maintenance and Support (milestone)
