oi_cycle_separation.Rd
Function to recategorise OSM data based on the type of cycle infrastructure.
oi_cycle_separation(osm_sf, remove=FALSE)
A sf
and data.frame
object containing OpenStreetMap
infrastructure data, obtained from the
osmextract
function.
Boolean, FALSE by default, if TRUE, removes ways that are not part of any dedicated cycling infrastructure.
The provided osm_sf
is returned with an additional column,
openinfra_cycle_infa
, which indicates the type of cycling infrastructure
mapped as being one of the following values:
c("[cycle crossing](https://tinyurl.com/cycle-crossing)", "[cycle lane](https://tinyurl.com/cycle-lane)", "Mixed traffic - 20 mph" (no cycling infrastructure, carriageway maxspeed is 20 mph), "Mixed traffic - NA maxspeed" (no cycling infrastructure, carriageway maxspeed value is NA), "Segregated - cycleway/track" ( infrastructure is segregated from carriageway by definition and is either a [cycleway](https://tinyurl.com/higway-cycleway) or a [cycle track](https://tinyurl.com/cycle-track)), "shared lane/busway" (there is a lane drawn for cyclists, but it is either shared with a [busway](https://tinyurl.com/sahre-bus) or a [shared lane](https://tinyurl.com/share-lane) with carriageway users)
This function recetegorises OSM data on cycling infrastructure to one of the protection categories defined within the LTN1/20 guidance (Mixed Traffic | Cycle Lanes | Protected Cycling Space).
Note: The osm_sf
must contain the following tags: c("cycleway",
"cycleway_left", "cycleway_right", "cycleway_both")
