MEASUREMENT SAMPLE

How North Station to Stony Brook was measured

The North Station to Stony Brook estimate uses 2,922 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.
