create_gtfs: Create a GTFS Feed from Tables

In GTFSwizard: Creating, Exploring, and Manipulating GTFS Files

Create a GTFS Feed from Tables

Description

Creates and validates a GTFS Schedule feed from data frames. The required files and fields follow the current GTFS Schedule reference, including its conditional rules for route names, stop locations, and service calendars.

Usage

create_gtfs(
  agency,
  routes,
  trips,
  stop_times,
  stops,
  calendar = NULL,
  calendar_dates = NULL,
  shapes = NULL,
  frequencies = NULL,
  transfers = NULL,
  fare_attributes = NULL,
  fare_rules = NULL,
  build_shapes = TRUE,
  zipfile = NULL,
  ...
)

Arguments

agency, routes, trips, stop_times, stops	Required GTFS tables supplied as data frames. 'agency_id' may be omitted when the feed contains one agency.
calendar, calendar_dates	Service calendar tables. At least one must define every 'service_id' used by 'trips'.
shapes, frequencies, transfers, fare_attributes, fare_rules	Optional GTFS tables.
build_shapes	Logical. If 'TRUE', infer straight-line shapes when 'shapes' is not supplied.
zipfile	Optional output path ending in '.zip'.
...	Additional named GTFS tables, such as 'pathways', 'levels', 'feed_info', or GTFS Fares v2 tables.

Value

A validated 'wizardgtfs' object, invisibly written as well when 'zipfile' is supplied.
