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

Description

Create a transfer table for a set of origins and destinations

Usage

create_transfer_table(
  origins,
  destinations,
  streetnet,
  d_limit = Inf,
  min_time = 120,
  ...
)

Arguments

origins	A data.table object containing the origin locations of the transfer trips. See details.
destinations	A data.table object containing the destination locations of the transfer trips. See details.
streetnet	The street network as an object of class sfnetworks, dodgr_streetnet or dodgr_streetnet_sc.
d_limit	Upper distance limit (as-the-crow-flies) in meters to consider a possible transfer between an origin and a destination.
min_time	Minimum travel time for any transfer trip in seconds, independent of the calculated travel time by the routing algorithm.
...	Additional parameters passed on to streetnet_traveltimes(). When parameter streetnet is of class sfnetworks, these include the time_column and weight_column parameters. See streetnet_traveltimes() for details.

Details

Both origins and destinations should be given in the format of a stops table of a GTFS feed.

The format of a transfer table can be used to model both true transit transfer trips as well as access, direct and egress trips:

• When modelling access trips, the origins will be grid points and the destinations transit stop locations.

• When modelling egress trips the origins will be transit stop locations and the destinations grid points.

• When modelling direct trips both origins and destinations will be grid points.

• When modelling true transit transfer trips, both origins and destinations will be transit stop locations.
