add_access_tables: Add an access table to a GTFS feed

In triply-at/gtfsmulti: Creating, storing and analyzing multi-modal transportation networks

Description

Add an access table to a GTFS feed

Usage

add_access_tables(gtfs, ...)

Arguments

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 grid points and transit stops for that mode. Such a table can be created with create_transfer_table(), using grid points as origins and transit stop locations as destinations.

Details

The access 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 grid point in the reference grid to a transit stop location, using a certain transport mode. For each transport mode, corresponding travel times are stored in a separate column.

Value

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 access trips of a GTFS-Multi feed. See details.

Note

An access table already present in the input gtfs object will be overwritten.
