Project Meeting 2016.08.12 - ActivitySim/activitysim GitHub Wiki

#Task 4 Accessibilities

  • accessibilities implemented, tested, and documented
  • includes tracing
  • still need to trace temporary variables
  • exhausted accessibilities budget so simplified destination choice logsums will need to be done later if budget permits (see below)

#Task 7 Nested Logit

  • implemented for tour mode choice
  • initial implementation committed
  • only implemented for simple simulate, not interaction simulate (such as destination choice)
  • see activitysim.py/nested_simulate() and example/configs/tour_mode_choice.yaml to get started
  • rename mnl.py to nl.py since does nesting as well?
  • Ben to review and update documentation
  • Need to note which already implemented models should be nested logit instead of MNL as well

#Task 1 Project Admin

  • Bill issued verbal NTP for Task 10 on 08/11/16 so we'll get started on this
  • Task 10 starts with correctly removing NA alternatives and then re-running full model and tracing results for failed HHs
  • exhausted accessibilities budget so simplified destination choice logsums will need to be done under Task 8 if budget permits
  • we have spent about $100k of the $185k project budget
  • after Task 10, we'll start on Task 8
