Claim 2:
3. The computer-implemented method of claim 1, further comprising classifying an interaction between the AV and the actor as a collision, wherein the classifying the interaction comprises:
performing an interaction classification to identify a time step associated with an instance of the collision, wherein the interaction classification identifies the time step in a time sequence of a collision time interval that a first polygon intersection is found,
wherein the first polygon intersection identifies the collision time interval based on a first longitudinal margin of a plurality of longitudinal margins that indicates the collision; and

otherwise, for a time interval, performing an interaction classification to identify a spatial longitudinal margin accounted to be a minimum spatial longitudinal margin in a location interval of a reference path when the actor is predicted to be at a minimum distance from the candidate trajectory of the AV, or alternatively, identifying the time interval over a longitudinal location interval of the actor when it is predicted to have a minimum lateral offset value from the candidate trajectory of the AV.
