Standard RAPTOR search does not work with flex egress from a transfer stop

[hannesj]

Expected behavior

I would expect a flex egress to be found, even when it requires a walking transfer from the last transit stop to the stop where flex is boarded.

Observed behavior

Currently a flex vehicle can only be boarded from the same stop where the last alighting happens, or by walking to a flex area, where the vehicle can be boarded works. It also works, if the stop which flex is boarded from is served by scheduled traffic, so the only case that doesn't work, is when you want to board flex from a stop that is only served by flex, where no other of the stops on the flex route are scheduled stops.

This is due to EgressArrivalToPathAdapter#add only being called from EgressStopArrivalState#arriveByTransit via org.opentripplanner.transit.raptor.rangeraptor.standard.stoparrivals.Stops#transitToStop, not from org.opentripplanner.transit.raptor.rangeraptor.standard.stoparrivals.Stops#transferToStop

Strangely this works for us.

I must check our fork if we made the change you describe.

[hannesj]

This works with GTFS-Flex if the destination is another stop, as it will be routed to using the RAPTOR router. Can you test routing to a flex area rather than a stop

[leonardehrenfried]

The destination is an area. You're being dropped of at home:
