Existing Major Transit Stop Half Mile Buffer (Caltrans Data)

Estimated High Quality Transit Areas as described in Public Resources Code 21155, 21064.3, 21060.2. High Quality Transit Corridors are buffered a half-mile from the linear General Transit Feed Specification (GTFS) shape, while Major Transit Stops are buffered a half-mile from the point locations of stops in General Transit Feed Specification (GTFS) data or, for planned major transit stops, MPO-provided Regional Transportation Plan data. See https://github.com/cal-itp/data-analyses/tree/main/high_quality_transit_areas for additional details. Use GTFS schedule trips, stop_times, shapes, and stops to estimate whether corridor segments have scheduled headways of 20 minutes or less.
