Project Meeting 2022.07.21

Agenda

• Status Update on Phase 7 tasks

Action Items

• Michelle to schedule an offline discussion about Phase 7 project delivery
• Jeff to schedule a side technical conversation about data types and making changes to the main (non-sharrow) version of ActivitySim to reduce run-time and memory usage.

Meeting Notes

• Task 2-4: Sharrow Parts 1-3
  • Part 1 is almost done – should be done within a week or two
    • Testing functionality is done
    • Rigorous performance against old code – old code just takes a long time, with chunking turned as required by scope
    • Concerns about not just run time but also memory usage – group wants Jeff to report on that during the next update. Jeff has been working on understanding both runtime and memory implications.
    • This effort lead to discussions about reviewing data types that can be revisited.
    • Joe proposes dealing with old data types, make a better version of the old version of the model, and then use this as the benchmark for comparison to sharrow, so that running the old version doesn’t become a barrier to completing work on time. Suggested that the consortium put together a task order for this and issue in the next two weeks.
    • Jeff notes that it’ll be faster for him to get things done moving forward with what he’s already doing, rather than wait for a new task to be executed and then completed.
    • Jeff TO DO: have a side technical conversation about this topic.
  • Part 2 is getting 2- and 3-zone systems
    • Moving along, more progress to share in 2-3 weeks
  • Part 3 is time windows
    • Smallest effort
    • To be done in the next few months
  • Task 5: Trying to find a time to present on the school drop-off and pick-up model
    • Tours and trips are created
  • Task 6: Disaggregate accessibilities
    • Presenting next Tuesday
    • Made synthetic population procedure for the disaggregate accessibilities
    • Currently sending through the destination choice model
• Task 7: Shadow pricing – have not made much progress
• Task 8: Kind of incorporated into Task 5
• Michelle TO DO: Find a time offline to discuss timeline for project delivery
  • Final deadlines
  • Interim checkpoints
