gtfs_transfer_table — gtfs_transfer

Construct a transfer table for a GTFS feed.

gtfs_transfer_table(
  gtfs,
  d_limit = 200,
  min_transfer_time = 120,
  network = NULL,
  network_times = FALSE
)

Arguments

gtfs	A GTFS feed obtained from the extract_gtfs function.
d_limit	Upper straight-line distance limit in metres for transfers.
min_transfer_time	Minimum time in seconds for transfers; all values below this will be replaced with this value, particularly all those defining in-place transfers where stop longitudes and latitudes remain identical.
network	Optional Open Street Map representation of the street network encompassed by the GTFS feed (see Examples).
network_times	If `TRUE`, transfer times are calculated by routing throughout the underlying street network. If this is not provided as the `net` parameter, it will be automatically downloaded.

Value

Modified version of the gtfs input with additional transfers table.

Examples

# Use the following lines to extract a street network for a given GTFS feed.
# The result can then be passed as the `network` parameter.
if (FALSE) {
library (dodgr)
net <- dodgr_streetnet_sc (pts = gtfs$stops [, c ("stop_lon", "stop_lat")])
}
