Project Meeting 2022.08.16 - ActivitySim/activitysim GitHub Wiki

Meeting Notes

Review of school pickup/dropoff

  • Presentation: school_escorting_implementation_pt4.pptx
  • Pull request is out, and all tests are passing now
  • Added extra logging that includes reporting the maximum number of tours
  • Still getting a few errors related to scheduling that haven’t been figured out
  • Next steps is to go into the calibration part of the implementation
  • Preliminary results
    • Compared SANDAG results with MTC Extended
    • MTC Extended has a slightly higher overall escorting rate (20% of households, vs 14% in SANDAG)
    • In MTC extended example, 50% of escorting tours are created by school escorting model, essentially doubling escorting tours.
    • Kept calibration constants from SANDAG’s CT-RAMP implementation
  • Status
    • To do in the next few days:
      • Another pull request after fixing scheduling issues
      • Add/adjust calibration constants (potentially) in another pull request
      • Merge with new develop branch and pass tests
      • Document
  • Longer term
    • Implement in SANDAG

Follow-up on questions related to timing and versions from August 11 meeting:

  • What is the reason for introducing this model at this time to ActivitySim. Can we wait to roll out a version that includes this model until we can re-estimate? Will this be part of a new version?
  • Discussion has been postponed until Joe can provide his input
