Segregation levels — classify_cycle_infrastructure • osmactive

This function classifies OSM ways in by cycle infrastructure type levels for a given dataset.

Usage

classify_cycle_infrastructure(
  osm,
  min_distance = 10,
  classification_type = "Scotland"
)

Arguments

osm: The input dataset for which segregation levels need to be calculated.
min_distance: The minimum distance to the road for a cycleway to be considered off-road.
classification_type: The classification type to be used. Currently only "Scotland" is supported.

Value

A an sf object with the new column cycle_segregation that contains the segregation levels.

Details

See wiki.openstreetmap.org/wiki/Key:cycleway and taginfo.openstreetmap.org/keys/cycleway#values for more information on cycleway values used to classify cycle infrastructure.

Currently, only the "Scotland" classification type is supported. See the Scottish Government's Cycling by Design for more information.
