p “pick up only” – the bus will only stop to pick up passengers

s “set down only” – the bus will only stop to drop passengers off

Seen at stop is when the operator reported the bus at or near that stop, not its exact arrival time. Expected times are estimates. A dash means no time has been reported.

Planned, expected and observed values remain separate. Blank observations are never presented as on-time.
