Project Meeting 2021.03.04 - ActivitySim/activitysim GitHub Wiki

Task 1 Project Management (milestone)

  • Some revisions to the bench contract will be shared with the consultants
  • Partners please review the phase 6b scope Joe shared
  • AMPO and Joe discussed the various technical resources needed and will discuss some more soon
  • SEMCOG university model
    • How transferrable is the model to other regions/universities?
    • Could be useful to GATech and UW
    • Like a micro ABM within a regional ABM
    • Would probably be of value to other places
    • Size terms using building capacity instead of enrollment and where students live in the synpop is critical
    • Should look at the ASU survey as well
  • ARC presentation
    • Does the use of np.log versus np.log1p have a material difference in the system? Do we need to make and revisions to the software as a result?
  • PSRC/SANDAG add runtimes to multi-region timing runtimes by submodel
    • Let's have folks add to it over time
    • SANDAG runtimes without presampling....and will get faster with representative logsums
    • ActivitySim should always continue to work on performance. Something great about ActivitySim is that it is worth investing in (...worth making faster)
  • PopulationSim multiprocessing PR getting close to pullable (is that a word?)
  • FYI, PSRC using latest PopSim and results are better, see conversation here

Task 2 Complete Estimation Mode (milestone)

  • Nothing new to report

Task 3 Telecommute Model in Cooperation with SEMCOG (milestone)

  • I need to work on the design page some more

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

  • I need to work on the design page some more

Task 5 Performance Enhancements (milestone)

  • Jeff started on representative logsums
  • PSRC testing presampling
  • I'm going to merge develop2 to develop

Task 6 Prototype multiple models test system (milestone)

  • Reviewed ODOT's input checker (including the list of checks here)
  • The ODOT checker reminds me of the task 7 work below
  • I need to work on the plan some more
  • Like the new agency examples, added a simple regression test to check overall results to our core example example_mtc

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

  • No updates

Task 8 Maintenance and Support (milestone)

  • Continued to help PSRC get their example working, which it now does
  • Due to example_mtc regression test above, found and fixed a bug in multiprocessing repeatability related to zone sequencing
