Meeting Notes

Project Admin

  • Liaison with European ABM association
    • Inquiry stemmed from European Transport Conference (ETC) where they noted they don’t have many ABMs and was looking to connect with ActivitySim
    • Interest in ABMs in Europe, but they are very behind the US.
      • Climate change and energy consumption are driving motivations
      • A lot of individual operators have their own models
    • Joe, Alex, or an agency staff could present to this group to show the viable collaboration across agencies and industry.
  • Someone from Dubai asked MWCOG about their use of ActivitySim and MWCOG responded

Phase 9a Progress

  • Currently closing out BayDAG PRs
  • Working on various bug fixes
    • Automatically drop unneeded columns in choosers table
      • Not sure if it’s windows vs mac thing; CS could test on their windows server.
      • Sijia to see if she can duplicate her anomalous results.
      • If problem goes away, move forward with merging.
      • If problem does not go away, we’ll have more concrete information to evaluate and dig into it a little more.
  • Run BayDAG end-to-end, possibly without sharrow
    • CS working to run test-size BayDAG end-to-end without sharrow.
    • Small issues with getting components to work with sharrow.
      • The components that were written as extensions, and not as core components, don’t have all the same infrastructure to do things like skip sharrow. Jeff/CS went through all the core components to make a consistent set-up to skip sharrow in any of the core components. The extension models are out of sync of that, they will need to be updated in a similar way.
      • There are instances where there is re-indexing that sharrow isn’t able to handle, so moving those to preprocessors. CS is about halfway through the components.
      • In a few more days, hope to get through all the model components and show results.
  • School escorting optimization is close to being done and should be run on the MTC example next week.
  • Planning for a technical check-in on Tuesday
