Get total extension of GTFS feed routes

Usage

get_network_extension(
  gtfs,
  route_identifier = "route_id",
  direction_wise = TRUE,
  unified = FALSE,
  date = GTFShift::calendar_nextBusinessWednesday(),
  use_osm_routes = NA,
  overline = FALSE
)

Arguments

gtfs

tidygtfs. GTFS feed.

direction_wise

Boolean (Default TRUE). If TRUE, extension considers sum of both directions. Otherwise, only one direction is considered.

unified

Boolean (Default FALSE). If TRUE, overlapping route segments are only counted once in the total extension.

date

Date (Default GTFShift::calendar_nextBusinessWednesday()). Reference date to consider when analyzing the GTFS file.

use_osm_routes

osmdata::opq (Default NA). If overpass query for transit network is defined, analysis is performed considering OSM route geometry, using GTFShift::osm_shapes_to_routes.

route_identifier.

String. (Default "route_id"). routes.txt attribute that identifies routes. Accepted values: route_id, route_short_name, route_long_name.

Value

The routes extension, in meters.

Details

This method calculates the sum of the GTFS feed routes length, considering, for each, the shape of the variant with the highest frequency for the given date (using GTFShift::get_route_frequency_hourly()). For a detailed example, see the vignette("analyse").

Examples

if (FALSE) { # \dontrun{
gtfs = GTFShift::load_feed("gtfs.zip")
route_extension = GTFShift::get_network_extension(gtfs)
} # }
