SIRI-VM 2.0

Realtime vehicle position data is delivered through a vehicleMonitoringDeliveryStructure containing one or more VehicleActivity elements.

VehicleActivity

The vehicle position for one vehicle is contained in a VehicleActivity element. The following fields are supported by Samtrafiken. Any fields or attributes not on the list are ignored.

Field	Required	Notes

Field	Required	Notes
RecordedAtTime	Required
ValidUntilTime	Required	Ignored by Samtrafiken
MonitoredVehicleJourney > LineRef	Required	Reference to `Line` in the static data, for example `SE:022:Line:1234`
MonitoredVehicleJourney > VehicleRef	Required	A unique id for the physical vehicle. If the static data contains this vehicle, then the id should match the static data. The value should be a positive number.
MonitoredVehicleJourney > FramedVehicleJourneyRef > DatedVehicleJourneyRef	Required	Reference to `ServiceJourney` in the static data, for example `SE:022:ServiceJourney:1234567-12345`
MonitoredVehicleJourney > FramedVehicleJourneyRef > DataFrameRef	Required	Trip start date in YYYY-MM-DD format. Used to match with static data
MonitoredVehicleJourney > VehicleLocation > Latitude	Required	Northing coordinate, WGS84
MonitoredVehicleJourney > VehicleLocation > Longitude	Required	Easting coordinate, WGS84
MonitoredVehicleJourney > VehicleLocation[SrsName]	Optional	WGS84 when unspecified. WGS84 is recommended since this avoids possible loss of resolution during conversion. Valid values: WGS84 4326 SWEREF99TM RT90
MonitoredVehicleJourney > Bearing	Optional	Compass bearing in degrees (0-359.99), rounded down to the nearest integer by Samtrafiken.
MonitoredVehicleJourney > Velocity	Optional	Speed, in kilometers per hour, rounded down to the nearest integer by Samtrafiken..
MonitoredVehicleJourney > Occupancy	Optional	Realtime occupancy. One of `full` `standingAvailable` `seatsAvailable`
MonitoredVehicleJourney > Delay	Required	Ignored by Samtrafiken, Samtrafiken reads delays from SIRI-ET streams. Required in order to adhere to the Nordic SIRI profile. Duration which can be negative if the vehicle is early. `PT0S` when there are no delays.
