go get github.com/artonge/go-gtfs

Examples

Load one directory containing GTFS files:

path/to/gtfs_files
├── agency.txt
├── attributions.txt
├── calendar_dates.txt
├── calendar.txt
├── fare_attributes.txt
├── fare_rules.txt
├── feed_info.txt
├── frequencies.txt
├── levels.txt
├── pathways.txt
├── routes.txt
├── shapes.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
│   ├── attributions.txt
│   ├── calendar_dates.txt
│   ├── calendar.txt
│   ├── fare_attributes.txt
│   ├── fare_rules.txt
│   ├── feed_info.txt
│   ├── frequencies.txt
│   ├── levels.txt
│   ├── pathways.txt
│   ├── routes.txt
│   ├── shapes.txt
│   ├── stops.txt
│   ├── stop_times.txt
│   ├── transfers.txt
│   └── trips.txt
└── gtfs2
    ├── agency.txt
    ├── attributions.txt
    ├── calendar_dates.txt
    ├── calendar.txt
    ├── fare_attributes.txt
    ├── fare_rules.txt
    ├── feed_info.txt
    ├── frequencies.txt
    ├── levels.txt

    ├── routes.txt
    ├── shapes.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
	Agencies       []Agency
	Attributions   []Attribution
	Calendars      []Calendar
	CalendarDates  []CalendarDate
	FareAttributes []FareAttribute
	FareRules      []FareRule
	FeedInfos      []FeedInfo
	Frequencies    []Frequency
	Levels         []Level
	Routes         []Route
	Pathways       []Pathway
	Shapes         []Shape
	Stops          []Stop
	StopsTimes     []StopTime
	Trips          []Trip
	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"`
}
