Add GTFS v1 fares (fare_attributes + fare_rules) from NeTEx

Source: R/netex_to_gtfs_fares.R

Builds the original-specification GTFS fare tables from parsed NeTEx fare files and attaches them to a GTFS object. A `zone_id` column is added to `stops` giving each stop its fare zone, and `fare_rules` maps each origin-zone / destination-zone pair on a route to a fare.

gtfs_add_fares_v1(gtfs, netex_list, payment_method = 0L)

Arguments

gtfs

a GTFS object (named list).

netex_list

list of parsed NeTEx fare objects (already filtered to the product(s) you want, see [netex_filter_fares()]).

payment_method

integer, GTFS `payment_method` (0 = paid on board, 1 = paid before boarding). Default 0, matching on-board bus ticket sales.

Value

the GTFS object with `fare_attributes`, `fare_rules` and a `stops$zone_id` column added.

Details

Because GTFS v1 stores a single `zone_id` per stop, this works cleanly for a single route; when several routes share a stop but place it in different fare zones only the first assignment is kept (with a warning).
