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 ├── pathways.txt ├── routes.txt ├── shapes.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 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_desc" URL string csv:"route_url" Color string csv:"route_color" TextColor string csv:"route_text_color" }
