Tract demographic layer

Data: MBTA Reliability (MassDOT ArcGIS) · MBTA GTFS · US Census ACS 5-year 2022 · TIGER 2022 cartographic boundaries. Reliability metric = Headway / Schedule Adherence on-time count ÷ scheduled count, aggregated Sep 1 – Nov 29 2025, weighted by trip volume. Tract-level OTP = ridership-weighted average across routes serving stops in the tract. This is a demo — methodology can be tightened.
