SIRI-SX 2.0

SIRI-SX is used to model textual descriptions of disruptions, or deviations from the planned public transport information. The messages can be applied directly to stops, lines, vehicles etc. in the already existing public transport data by the use of ID references.

Structure

The root element situationExchangeDeliveryStructure includes a response timestamp (when the XML structure was rendered), subscriptionRef in case publish/subscribe is used for the data transfer, and exactly one Situations element.

The tables below list which fields are supported by Samtrafiken. Any fields or attributes not on the list are ignored.

AffectedLine

Element

Required

Notes

LineRef

Required

Should reference a line in the static data

Routes > AffectedRoute

https://samtrafiken.atlassian.net/wiki/spaces/SamtrafikenOpenData/pages/4400152638/SIRI-SX+2.0#AffectedRoute

Not set if all routes are affected

If set the situation only applies to the specified routes are marked as affected

AffectedRoute

AffectedRoutes belong to AffectedLines, any filters applied here, such as only specific stops being affected, are combined with the affected line information. Only “Stop A”, in combination with “Only line 1”, will result in “Applies at stop A for traffic on line 1”.
