In the vehicle_cut_out_behind_ego evaluation scenario, the vehicle_actor drives behind the Ego in the same lane and then cuts out to the adjacent lane.
Scenario location: $FTX/logiq/scenario_library_post_match/vehicle_cut_out/vehicle_cut_out_behind_ego
362.1 Actors
The actors associated with this scenario are as follows:
| Actor | Description | Type | Depiction |
|---|---|---|---|
ego |
Vehicle under test | vehicle |
![]() |
vehicle_actor |
Vehicle behind the Ego in the same lane, that moves into an adjacent lane | vehicle |
![]() |
362.2 Scenario phases
The phase descriptions are as follows:
362.2.1 cut_out_behind_ego_start
Ego: The Ego drives in the same lane as the vehicle_actor at the start and continues to drive in the same lane.
vehicle_actor: The vehicle_actor drives behind the Ego in the same lane while maintaining an initial distance between
min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units.
It then initiates a lane change and completes the maneuver at the end of the phase.
362.2.2 cut_out_behind_ego_end
Ego: The Ego continues driving in the same lane.
vehicle_actor: The vehicle_actor drives in a lane adjacent to the Ego.
