Specialization AbnormalTraffic (Traffic Queue Formation)
The type AbnormalTraffic is derived from TrafficElement and is used to describe a traffic situation that is busier than normal, such as in the case of a traffic queue.
Within the Traffic Reports data service, this is the most common specialization. In addition to the basic elements of SituationRecord, additional information about the abnormal traffic situation is included in the extra elements. The structure is as follows (elements inherited from TrafficElement are shown in shortened form):
Elements
An overview of elements that occur in every specialization of a situationRecord can be found here.
In the case of the AbnormalTraffic specialization, these elements are supplemented with several additional elements of this specialization.
| Element | Type | Mandatory | Domain | Description |
|---|---|---|---|---|
| abnormalTrafficType | AbnormalTrafficTypeEnum | No | stationaryTraffic, queuingTraffic, slowTraffic, unspecifiedAbnormalTraffic | This element describes the severity of the traffic queue and is included if a traffic queue is being described. |
| queueLength | MetresAsNonNegativeInteger | No | >=0 | This element describes the length of the traffic queue (or abnormal traffic situation) and must be included if a traffic queue is being described and thus the element abnormalTrafficType is included. |
| relativeTrafficFlow | RelativeTrafficFlowEnum | No | trafficVeryMuchHeavierThanNormal, trafficHeavierThanNormal, trafficFlowNormal, trafficLighterThanNormal, trafficVeryMuchLighterThanNormal | Assessment of the traffic flow conditions compared to the normally expected conditions at this date/time. |
| trafficFlowCharacteristics | TrafficFlowCharacteristicsEnum | No | erraticFlow, smoothFlow, stopAndGo, trafficBlocked | The consistency (stability) of the traffic flow. |
| trafficTrendType | TrafficTrendTypeEnum | No | trafficBuildingUp, trafficEasing, trafficStable | Description of a trend in the change of the traffic situation. |
