TimeToCollisionCondition: General handling of relativeDistanceType=lateral
Describe the problem
For us, the general handling of the TimeToCollisionCondition using a lateral relative distance type is a bit unclear. Considering e.g. the case below (taken from Issue #304):
Considering the displayed case, I would like to ask how a TimeToCollisionCondition of entity A with relativeDistanceType=lateral and timeToCollisionConditionTarget=entityRef=B shall evaluate if entity A changes its lane to entity B's lane.
Describe your research
According to the discussion in issue #304 (closed) and the enumeration RelativeDistanceType from the OpenSCENARIO V1.2.0 Model Documentation, we know how to compute the lateral distance in such a case. However, the TimeToCollisionCondition does not mention how we should handle situations as depicted above, where no collision will happen at all; however, the lateral distance delta_t can be computed and gets smaller if A changes to the lane of B.
Ask your question
So my basic question is, how should those cases be handled in general? Should the TimeToCollisionCondition compute a time (and compare it to the specified time value until a collision) in the lateral case even though no collision will happen due to an appropriate longitudinal offset; or should the longitudinal position be also taken into account for the evaluation?
Thank you very much for your help in advance!
