Extracts the transit network from a network.dat file (built with setup_r5()) in sf format.

transit_network_to_sf(r5r_core)

Arguments

r5r_core

An object to connect with the R5 routing engine, created with setup_r5().

Value

A list with two components of a transit network in sf format: route shapes (LINESTRING) and transit stops (POINT). The same route_id/short_name might appear with different geometries. This occurs when the same route is associated to more than one shape_ids in the GTFS feed used to create the transit network. Some transit stops might be returned with geometry POINT EMPTY (i.e. missing spatial coordinates). This may occur when a transit stop is not snapped to the road network, possibly because the GTFS feed used to create the transit network covers an area larger than the .osm.pbf input data.
