add_egress_tables.RdAdd an egress table to a GTFS feed
add_egress_tables(gtfs, ...)An object of class gtfs.
One or more keyword arguments, with the key being the name of a
specific transport mode, and the value being a
data.table object containing the travel times
between transit stops and grid points for that mode. Such a table can be
created with create_transfer_table(), using transit stop
locations as origins and grid points as destinations.
An object of class gtfs. This is a
list of multiple data.table objects
corresponding to the different dataset files of a GTFS feed. In addition to
those, the returned object will contain a
data.table representing the egress trips of a
GTFS-Multi feed. See details.
The egress table of a GTFS-Multi feed always has the same structure as the transfer table in a regular GTFS feed. Each row contains the minimum travel time needed to travel from a transit stop location to a grid point in the reference grid, using a certain transport mode. For each transport mode, corresponding travel times are stored in a separate column.
An egress table already present in the input gtfs object will be overwritten.
