Load GTFS files in golang

Install

go get github.com/artonge/go-gtfs

Examples

Load one directory containing GTFS files:

path/to/gtfs_files
├── agency.txt
├── calendar_dates.txt
├── calendar.txt
├── routes.txt
├── stops.txt
├── stop_times.txt
├── transfers.txt
└── trips.txt

g, err := gtfs.Load("path/to/gtfs_files", nil)

Load a directory containing sub directories containing GTFS files:

path/to/gtfs_directories
├── gtfs1
│   ├── agency.txt
│   ├── calendar_dates.txt
│   ├── routes.txt
│   ├── stops.txt
│   ├── stop_times.txt
│   ├── transfers.txt
│   └── trips.txt
└── gtfs2
    ├── agency.txt
    ├── calendar_dates.txt
    ├── calendar.txt
    ├── routes.txt
    ├── stops.txt
    ├── stop_times.txt
    ├── transfers.txt
    └── trips.txt

gs, err := gtfs.LoadSplitted("path/to/gtfs_directories", nil)

You can then access the data through the GTFS structure. That structure contains arrays of approriate structures for each files.

type GTFS struct {
	Path       string // The path to the containing directory
	Agency     Agency
	Routes     []Route
	Stops      []Stop
	StopsTimes []Stop
	Trips      []Trip
	Calendars  []Calendar
	Transfers  []Transfer
}

type Route struct {
	ID        string `csv:"route_id"`
	AgencyID  string `csv:"agency_id"`
	ShortName string `csv:"route_short_name"`
	LongName  string `csv:"route_long_name"`
	Type      int    `csv:"route_type"`
	Desc      string `csv:"route_url"`
	URL       string `csv:"route_desc"`
	Color     string `csv:"route_color"`
	TextColor string `csv:"route_text_color"`
}
