Measured, not promised.
TransitMeter pairs vehicle stop timestamps with the schedule active for each trip. We publish the median because one dramatic delay should not define an everyday journey, and the 90th percentile because riders still need to understand the bad end of normal.
We do not infer why a trip ran slowly. Construction, incidents, crowding and weather require separate evidence.
