Status Update on School Drop-off/ Pick-up Model

  • Presentation by RSG: school_escorting_implementation_pt1.pptx

  • Choices made for each bundle

  • First Set of Choices: School escorting options by direction

    • Weighted utility for chauffeur selection
      • Person type has the highest weight; lower person types are workers and have a lower weight, higher person type for those that aren’t working and are more likely to be able to chauffeur and have a higher weight
      • Women twice as likely as men to be selected, all other things being equal
    • Utility spreadsheet and preprocessor files (and their terms and specs) were reviewed with the group
    • What are the biggest difficulties when translating from java to ActivitySim, any simplifications?
      • Translating from the object trees to ActivitySim’s tables
      • Alternatives are just an input file now
  • Next Choices: tour level attributes

    • Pure escort tours need to be created; rideshare tours are already created because of the primary purpose (mandatory) tour
    • Tour mode could be user configurable. For the SANDAG implementation, it is auto only.
  • Next Choices: trip level attributes

    • No intermediate stops between home and school, only direct drop-off
  • Current status:

    • Tours are created
    • Rethinking tour ID sequencing
    • Still need to do trip level choices/variables
    • Pull request has been created, if anyone wants to take a look
