MEASUREMENT SAMPLE

How Brookline Hills to Science Park/West End was measured

The Brookline Hills to Science Park/West End estimate uses 3,226 completed direct-trip stop-timestamp pairs matched to the schedule active for each observed train.

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.
