Phase 8 Interim Tasks

  • Discussion about how hours spent should be reported.
    • Include notes/descriptions about who was working on what and approximate level of effort.
    • Joel to work with Joe offline to provide recommended language in the scope of work.
  • Meeting cadence
    • Willing to continue canceling Tuesday meetings if there aren't meaningful technical presentations to be given.

Phase 7 Task Updates

  • Tasks 2-4
    • Substantial updates to sharrow documentation
    • All sharrow related PRs consolidated into one
    • Jeff’s work is complete, just waiting for Phase 8 interim funding for code review
    • ACTION ITEM: Joe to ask AMPO if they can provide an NTP
  • Task 5: School Pickup
    • Done
  • Task 6: Disaggregate Accessibility – PR by Monday Oct 3 (updated estimated completion date)
    • Component is fully functional, with implementation in 2 zone system, works with multiprocessing
    • It is generating 5000 prototype households, 2000 sampled zones
    • Initial PR will include core functionality, but there will still be more work to be completed (such as testing, before the final PR)
    • Code review to be done on Initial PR, to be designated later
    • Potential presentation next Thursday on
  • Task 7: Shadow Pricing - PR by Monday Oct 3 (updated estimated completion date)
    • Implemented for school location choice
    • Noticed inconsistency between size term and constraint which is total enrollment. Can be an issue with jobs but less likely to occur. Tends to be more of a small sample problem.
    • Potential solutions:
      • Not worry about re-simulating students if there are no better solutions
      • Make constraint mechanisms specific to segments (like grade and high school students)
    • Adjustments to account for in-commuting. There are a few ways to implement the reduction, would like to discuss with the group. See the issue on Github for more information. It would be helpful if people could review the issue before Thursdays meeting to be ready to discuss.
