Need OP_SKIMS in trip destination model / error in ARC example model#545

There is a line in the spec for the example ARC model marked with the comment:

THIS IS WRONG ***** RIGHT HERE **** I CHANGED THE BELOW TO MAKE WORK MECHANICALLY

https://github.com/ActivitySim/activitysim/blob/master/activitysim/examples/example_arc/configs/trip_destination.csv#L16

It appears that whomever was building this file wanted to access three kinds of skim references:

  1. od_skims = fixed-origin to stop-location
  2. dp_skims = stop-location to fixed-primary-destination
  3. op_skims = fixed-origin to fixed-primary-destination (as if there was no stop)

The third type is not used in the canonical MTC model for trip destination, and it seems it was never coded into the trip destination component for ActivitySim. The current ARC example is just using the od_skims again as a placeholder for the missing op_skims to make it work "mechanically" (i.e. not crash) but it sure looks to me like the model spec file is wrong. The fix requires:

  • Make op_skims available in the trip destination component (and by extension, opt_skims; we can probably skip po_ and pot_)
  • Correct the trip destination spec file in prototype_arc
  • Verify outputs from prototype_arc model
  • Update tests

Note to developers: Do not close this issue until @guyrousseau (or his designee) can confirm that ARC gets the fix in their agency-maintained model as well, and not just in the consortium's example model. cc: @i-am-sijia

                          THIS IS WRONG ***** RIGHT HERE **** I CHANGED THE BELOW TO MAKE WORK MECHANICALLY
                          https://github.com/ActivitySim/activitysim/blob/master/activitysim/examples/example_arc/configs/trip_destination.csv#L16
                          It appears that whomever was building this file wanted to access three kinds of skim references:
                          1. od_skims = fixed-origin to stop-location
                          2. dp_skims = stop-location to fixed-primary-destination
                          3. op_skims = fixed-origin to fixed-primary-destination (as if there was no stop)
                          The third type is not used in the canonical MTC model for trip destination, and it seems it was never coded into the trip destination component for ActivitySim. The current ARC example is just using the od_skims again as a placeholder for the missing op_skims to make it work "mechanically" (i.e. not crash) but it sure looks to me like the model spec file is wrong. The fix requires:
                          •  Make op_skims available in the trip destination component (and by extension, opt_skims; we can probably skip po_ and pot_)
                          •  Correct the trip destination spec file in prototype_arc
                          •  Verify outputs from prototype_arc model
                          •  Update tests
                          Note to developers: Do not close this issue until @guyrousseau (or his designee) can confirm that ARC gets the fix in their agency-maintained model as well, and not just in the consortium's example model. cc: @i-am-sijia
