169. Vehicle Cut Out Exposing Vehicle Scenario evaluation scenario

In the vehicle_cut_out_exposing_vehicle evaluation scenario, the vehicle_actor drives ahead of the Ego in the same lane, with the Ego following behind. The vehicle_actor then changes lanes, revealing the exposed_actor which is also driving in the Ego’s lane.

Scenario location: $FTX/logiq/scenario_library_post_match/vehicle_cut_out/vehicle_cut_out_exposing_vehicle

169.1 Actors

The actors associated with this scenario are as follows:

Actor Description Type Depiction
ego Vehicle under test vehicle
vehicle_actor Cut out vehicle vehicle
exposed_actor Exposed vehicle vehicle

169.2 Scenario phases

The phase descriptions are as follows:

169.2.1 initial_phase

Ego: The Ego is driving in the same lane as the vehicle_actor, following behind it.

vehicle_actor: The vehicle_actor drives ahead of the Ego in the same lane and remains close to the Ego at a distance between min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units.

exposed_actor: The exposed_actor drives in the same lane as the Ego and the vehicle_actor, ahead of the vehicle_actor.

169.2.2 cut_out_phase

Ego: The Ego continues driving in the same lane.

vehicle_actor: The vehicle_actor drives in a lane adjacent to the Ego, revealing the exposed_actor to the Ego.

169.2.3 post_cut_out_phase

Ego: The Ego drives behind the exposed_actor in the same lane.

exposed_actor: The vehicle_actor drives ahead of the Ego in the same lane and remains close to the Ego at a distance between min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units.

169.3 Parameters

Use these parameters to constrain the scenario. If you do not set a specific value, the default value will be used.

max_cut_out_phase_duration time Maximal time of the cut_out_phase 3sec
min_post_cut_out_phase_duration time Minimal time of the post_cut_out_phase 0sec
max_post_cut_out_phase_duration time Maximal time of the post_cut_out_phase 3sec
speed_gap_threshold speed The time threshold for the vehicle_actor to be considered as driving on the same road as the Ego 10sec

The input items inherited from the sut.logiq_base_lane_following_scenario scenario are as follows:
