Types

type StopTimePair

type StopTimePair struct {
	// contains filtered or unexported fields
}

StopTimePair contains the to and from gtfs.StopTimeInstance for a stop transition on a gtfs.TripInstance

type VehicleStopStatus

type VehicleStopStatus int

VehicleStopStatus defines the possible relationship a vehicle has to a stop in GTFS

const (
	Unknown VehicleStopStatus = -1
	// IncomingAt indicates vehicle is just about to arrive at the stop (on a stop
	// display, the vehicle symbol typically flashes).
	IncomingAt VehicleStopStatus = 0
	// StoppedAt indicates vehicle is at the stop.
	StoppedAt VehicleStopStatus = 1
	// InTransitTo indicates vehicle has departed a previous stop and is in transit to the next stop.
	InTransitTo VehicleStopStatus = 2
)
