gtfsio offers tools for the development of GTFS-related packages. It
establishes a standard for representing GTFS feeds using R data types
based on the GTFS Schedule
Reference. It
provides fast and flexible functions to read and write GTFS feeds while
sticking to this standard. It defines a basic gtfs class which is
meant to be extended by packages that depend on it. And it also offers
utility functions that support checking the structure of GTFS objects.
Installation
Stable version:
install.packages("gtfsio")
Development version:
install.packages("gtfsio", repos = "https://r-transit.r-universe.dev")
# or
# install.packages("remotes")
remotes::install_github("r-transit/gtfsio")
Usage
GTFS feeds are read using the
import_gtfs()
function:
library(gtfsio)
path <- system.file("extdata/ggl_gtfs.zip", package = "gtfsio")
gtfs <- import_gtfs(path)
names(gtfs)
#> [1] "calendar_dates" "fare_attributes" "fare_rules" "feed_info"
#> [5] "frequencies" "levels" "pathways" "routes"
#> [9] "shapes" "stop_times" "stops" "transfers"
#> [13] "translations" "trips" "agency" "attributions"
#> [17] "calendar"
import_gtfs() returns a gtfs object which is a list of a tables. The
gtfs class might be extended by other packages using the constructor,
validator and methods provided by gtfsio:
class(gtfs)
#> [1] "gtfs" "list"
Use
export_gtfs()
to write GTFS objects to disk:
tmpf <- tempfile(fileext = ".zip")
export_gtfs(gtfs, tmpf)
zip::zip_list(tmpf)$filename
#> [1] "calendar_dates.txt" "fare_attributes.txt" "fare_rules.txt"
#> [4] "feed_info.txt" "frequencies.txt" "levels.txt"
#> [7] "pathways.txt" "routes.txt" "shapes.txt"
#> [10] "stop_times.txt" "stops.txt" "transfers.txt"
#> [13] "translations.txt" "trips.txt" "agency.txt"
#> [16] "attributions.txt" "calendar.txt"
