174.2 Scenario phases
The phase descriptions are as follows:
174.2.1 off_road_phase
vehicle_actor: The vehicle_actor drives at least veer_from_lane_threshold off the road,
within a longitudinal distance between min_longitudinal_distance_from_ego and max_longitudinal_distance_from_ego ahead of the
Ego and a lateral distance between min_lateral_distance_from_ego and max_lateral_distance_from_ego to the right of the Ego.
Ego: The Ego is driving on the road.
174.2.2 merging_phase
vehicle_actor: The vehicle_actor is driving on the road, not in a junction, and located within a distance between
min_longitudinal_distance_from_ego and max_longitudinal_distance_from_ego ahead of the Ego.
174.2.3 merged_phase
vehicle_actor: The vehicle_actor is driving on the road, positioned laterally to the left of the Ego,
at a distance between min_lateral_distance_from_ego and max_lateral_distance_from_ego.
The angle difference between the vehicle_actor and the Ego is between min_angle_diff and max_angle_diff.
