359.2 Scenario phases

The phase descriptions are as follows:

359.2.1 init_drive

Ego: The Ego drives in one lane, in the adjacent lane to the vehicle_actor.

vehicle_actor: The vehicle_actor drives at the adjacent lane, ahead of the Ego and remains in a range of min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units from the Ego during the entire phase.

359.2.2 change_lane

Ego: The Ego drives in one lane, behind the vehicle_actor.

vehicle_actor: The vehicle_actor changes lane to the Ego's lane, ahead of the Ego and remains in a range of min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units from the Ego during the entire phase.

359.2.3 post_phase

vehicle_actor: The vehicle_actor in the same lane during the entire phase.
