Verification

  • We fixed all the verification table issues and re-traced a HH to confirm the fixes
  • TM1 style shadow pricing looking much better, see plots below
  • Daysim style shadow pricing needed some fixes as well (after reviewing the code and discussing with Mark), which we have just about completed, see #250. We also updated the expression file as a result.
  • Updated the example to use ctramp method and more efficient damping factor of 0.7
  • Size term by iteration for zone 1 work low income segment below

  • Implemented mode choice logsums for mandatory tour time-of-day choice as part of the verification/clean-up
  • Now working on a 10% sample run of the subsequent submodels, but ran into tour mode choice sampling and logsums not being implemented for escort tours. Should we go ahead and implement?
  • We plan to continue to trace calculations expression-by-expression to ctramp and to add expressions to force choices for the trace household to match TM1 so we can compare utilities

Project admin

  • We've spent about $145k of the $210k budget to date, ~$65k remaining
  • Our progress report is really starting to look complete
  • As we discussed at TRB, we prioritized verification over support for two zone system and assistance to ARC/SANDAG. These tasks were budgeted at $80k total so we're now into those budgets. Should we continue to reallocate the budget for verification?
  • The updated DBE GFE looked good to AMPO
