merge_gtfs: Merge Two GTFS Feeds

In GTFSwizard: Creating, Exploring, and Manipulating GTFS Files

Merge Two GTFS Feeds

Description

Combines two feeds table by table. By default, all identifiers and their foreign-key references receive feed-specific suffixes, preventing accidental collisions.

Usage

merge_gtfs(gtfs_x = NULL, gtfs_y = NULL, suffix = TRUE, ...)

Arguments

gtfs_x, gtfs_y	GTFS objects.
suffix	Logical. Append '.x' and '.y' to identifiers when 'TRUE'.
...	Supports the legacy arguments 'gtfs.x' and 'gtfs.y'.

Details

Standard references in routes, trips, stop times, shapes, calendars, frequencies, transfers, pathways, fare tables, networks, and booking rules are updated together. Non-standard tables are row-bound without identifier rewriting.

Value

A validated 'wizardgtfs' object.

merged <- merge_gtfs(for_rail_gtfs, for_rail_gtfs, suffix = TRUE)
