* @field rollAcceleration: optional Roll acceleration of object from the ITS-S's reference point at the time of measurement, in a pre-defined coordinate system.
* The angular acceleration is measured with positive values considering the object orientation turning counter-clockwise around the x-axis.
*
* @field @field pitchAcceleration: optional Pitch acceleration of object from the ITS-S's reference point at the time of measurement, in a
* @field pitchAcceleration: optional Pitch acceleration of object from the ITS-S's reference point at the time of measurement, in a
* pre-defined coordinate system. The angular acceleration is measured with positive values considering the object orientation turning counter-clockwise around the y-axis.
*
* @field yawAcceleration: optional Yaw acceleration of object from the ITS-S's reference point at the time of measurement, in a pre-defined coordinate system.
* @field subjectStation: optionally indicates one "other" traffic participant identified by its ITS-S.
*
* @field safeDistanceIndicator: indicates whether the distance between the ego ITS-S and the traffic participant(s) is safe.
* If subjectStation is present than it indicates whether the distance between the ego ITS-S and the traffic participant in @field subjectStation is safe.
* If subjectStation is present than it indicates whether the distance between the ego ITS-S and the traffic participant inidcated in the component subjectStation is safe.
*
* @field timeToCollision: 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.
