gtfs_route_headway: Route headway

In gtfsrouter: Routing with 'GTFS' (General Transit Feed Specification) Data

Route headway

Description

Calculate a vector of headway values – that is, time intervals between consecutive services – for all routes between two specified stations.

Usage

gtfs_route_headway(
  gtfs,
  from,
  to,
  from_to_are_ids = FALSE,
  grep_fixed = TRUE,
  quiet = FALSE
)

Arguments

gtfs	A set of GTFS data returned from extract_gtfs or, for more efficient queries, pre-processed with gtfs_timetable.
from	Names, IDs, or approximate (lon, lat) coordinates of start stations (as stop_name or stop_id entry in the stops table, or a vector of two numeric values). See Note.
to	Corresponding Names, IDs, or coordinates of end station.
from_to_are_ids	Set to TRUE to enable from and to parameter to specify entries in stop_id rather than stop_name column of the stops table.
grep_fixed	If FALSE, match station names (when passed as character string) with grep(..., fixed = FALSE), to allow use of grep expressions. This is useful to refine matches in cases where desired stations may match multiple entries.
quiet	If TRUE, display a progress bar

Value

A single vector of integer values containing headways between all services across a single 24-hour period
