Project Meeting 2021.03.25 - ActivitySim/activitysim GitHub Wiki

Task 1 Project Management (milestone)

  • Informal RFPs drafted for internal review and planned to go out in a couple weeks
  • Update on SANDAG performance work, see multi-region timing
    • Including the tap lines file makes a big difference
    • SANDAG helper funds need to be spent by 4/15; Jeff working on it
    • Including tap lines is optional
    • What's the impact on the model results / quality? We've pretty much just always included it since it removes suboptimal options
    • TM2 development assigned the onboard survey and compared results to the TVPB, which is a good way to understand how the tap lines impacted results
    • Remember the code is much better too
    • Code should be about as fast as CT-RAMP (and if not then let's try to make it faster)
    • Having more RAM really helps, and the amount you need depend is tied to the number of CPUs
    • Would be good to add more documentation on how to explore/tune memory/processors/chunking
    • Would be good to test different configs on different AWS or Azure machines now to provide more guidance
    • ARC has 64 core 512GB RAM machine
    • We'll keep folks posted on progress

  • I'll then review and integrate as needed

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

  • Will be updating the user guide example materials to support multiple examples since we now have several

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

  • Discussed potential improvements list wiki page

  • We'll then work through the list, implementing what we can with the task budget
  • We'll link to the issues from the page

Task 8 Maintenance and Support (milestone)

  • Made some improvements to non-mandatory tour scheduling to speed it up
