Project Meeting 2022.05.26

Admin

• AMPO sent out the funding agreements with new/revised invoices yesterday. Everyone aligned with fiscal year (July 1 to June 30) but flexible with length of contract. To best avoid confusion, Joe to send AMPO an edited version with the correct dates and resend to the partners.
• CMAP is going to be a new partner.

Technical Updates

• Phase 6 vehicle type code review: Elizabeth and Sijia have reviewed and submitted comments. They are just waiting to hear to hear back from RSG.
  • For the vehicle type model moving forward, we may want to monitor this currently ongoing survey effort https://www.bts.gov/vius
• WSP forked ActivitySim for a new MTC model. Question about whether or not the changes they are making would want to be merged into the main ActivitySim code.
  • CDAP model changes – adding household level join for utility for the CDAP model component. Existing feature in TM2, also exists in SANDAG model – both models have this difference in CDAP component of the Java model.
  • Sijia and Wu San to present to the group on the changes proposed, so we can understand the implications.
  • Wu San, Sijia, Joel, etc. to gather separately to discuss when would be a good time to present an inventory of what they’ve changed.

Model Inventory and Evaluation

• Model Inventory update
  • Some folks have added to the Google Spreadsheet
  • Request to differentiate between status update versus what is completed and ready for being a donor model, if someone wanted to use it – new row added
  • This list is helpful for Activity release version: https://github.com/ActivitySim/activitysim/releases. New row added to allow updater to include the release utilized.
• Update on 2 vs 3 zone report
  • MTC is moving to the 2 zone system for TM2 – they will be sending the report to Joe soon. Dave Ory agreed to make a presentation, date TBD.
  • ARC is keeping a 1 zone system for now.
  • Wu San/SANDAG is unsure about their future zone system. He’s concerned about run time and memory implications.
• Many folks still need to add to the ActivitySim Model Evaluation doc, which includes things that are or are not working with ActivitySim.
