get_corridor: Identify High-Frequency Transit Corridors

In GTFSwizard: Creating, Exploring, and Manipulating GTFS Files

Identify High-Frequency Transit Corridors

Description

Finds frequently served adjacent stop pairs, joins connected pairs into corridors, and measures them in a local metric CRS.

Usage

get_corridor(gtfs, i = 0.01, min_length = 1500, ...)

Arguments

gtfs	A GTFS object.
i	Proportion of the highest-frequency stop pairs to retain. Must be greater than 0 and no greater than 1.
min_length	Minimum corridor length in meters.
...	Supports the legacy argument 'min.length'.

Value

An 'sf' object with 'corridor', list-columns 'stop_id' and 'trip_id', numeric 'length' in meters, and WGS84 geometry. Segments are straight lines between stop coordinates, not shape geometry.
