Agenda

  • Admin updates
    • Joe working on the AMPO conference presentation with RSG/SEMCOG and WSP/ARC
    • Joe working on scheduling next stage of scoping Phase 7
  • Progress on Airspeed velocity performance benchmarking improvements
    • System is working and we now have examples for mtc and sandag
    • Jeff wrote documentation for how to use as well
    • RSG or WSP to review once ready
    • 3 zone system uses caching so that speeds things up; maybe we can use for other purposes as well
    • Jeff will add multithreading benchmarking as well
    • It would be good to have our own benchmarking server for all testing for all parties involved to best control for differences
    • Can we just use an Amazon could instance instead? Depends on cost, use, etc.
    • Setup should integrate with the test system (like the DaySim test system with Azure Pipeline)
    • Setup allows for profiling as well, which is handy
    • PSRC example calls expensive adjacent_window_run_length expression twice, which is not needed
    • Next steps, Newman finish up and then RSG/WSP review
  • Discuss tour OD choice model contribution from SANDAG pull request
    • I shared the tour OD choice model slides
    • An additional purpose of the exercise was to build confidence for migrating the core resident model to ActivitySim, which it did
    • Additional reasons model developed was to test station choice and station mode choice policies
    • Next steps, address comments and further discuss if needed
