San Francisco Bay Region High Quality Transit Stops

This feature set provides estimated stops along High Quality Transit Corridors, plus major transit stops for bus rapid transit, ferry, and rail modes as described in Public Resources Code 21155, 21064.3, and 21060.2. Existing stops are calculated from General Transit Feed Specification (GTFS) data. Planned major transit stops are from Metropolitan Planning Organization-provided Regional Transportation Plans. See https://github.com/cal-itp/data-analyses/tree/main/high_quality_transit_areas for additional details. Caltrans used GTFS schedule trips, stop_times, shapes, and stops to estimate whether corridor segments have scheduled headways of 20 minutes or less.
