### <a name="RoadSegmentReferenceId"></a>RoadSegmentReferenceId
* _region_ of type [**Identifier2B**](#Identifier2B) OPTIONAL<br>
the optional identifier of the entity that is responsible for the region in which the road segment is placed.
It is the duty of that entity to guarantee that the [**Id**](#Id) is unique within the region.
* _id_ of type [**Identifier2B**](#Identifier2B) <br>
**Categories:** GeoReference information

### <a name="SafeDistanceIndication"></a>SafeDistanceIndication
This DF provides the safe distance indication of a traffic participant with other traffic participant(s).
* _subjectStation_ of type [**StationId**](#StationId) OPTIONAL<br>
optionally indicates one "other" traffic participant identified by its ITS-S.
* _safeDistanceIndicator_ of type [**SafeDistanceIndicator**](#SafeDistanceIndicator) <br>
indicates whether the distance between the ego ITS-S and the traffic participant(s) is safe.
If subjectStation is present then it indicates whether the distance between the ego ITS-S and the traffic participant indicated in the component subjectStation is safe.
* _timeToCollision_ of type [**DeltaTimeTenthOfSecond**](#DeltaTimeTenthOfSecond) OPTIONAL<br>
optionally indicated the time-to-collision calculated as sqrt(LaDi<sup>2</sup> + LoDi<sup>2</sup> + VDi<sup>2</sup>/relative speed
and represented in the nearest 100 ms. This component may be present only if subjectStation is present.
