Hello,
the travel time of public transport connections is taken directly from your
schedule input and includes the time to wait for the bus. Please recheck
the loaded schedule for the travel time from the origin stop to the
destination stop. See
https://sumo.dlr.de/docs/Simulation/Public_Transport.html#public_transport_schedules
For public transport stages, the edge list only holds the arrival edge
rather than the whole route of the public transport vehicle. This is for
technical reasons (the graph of connected public transport stations is used
instead of the graph of network edges during this part of the route search).
regards,
Jakob
