335. Ego traverse junction with NPC evaluation scenario

In the ego_traverse_junction_with_npc evaluation scenario, the Ego traverses a junction while there is an NPC in the same junction.

Scenario location: $FTX/logiq/scenario_library_post_match/junctions/ego_traverse_junction_with_npc

335.1 Actors

The actors associated with this scenario are as follows:

Actor Description Type Depiction
ego Vehicle under test vehicle
vehicle_actor Vehicle actor vehicle
Figure 1: Ego traverse junction with NPC

335.2 Scenario phases

The phase descriptions are as follows:

335.2.1 sut_and_npc_in_junction

Ego: The Ego is less than max_distance_from_junction away from a junction.

vehicle_actor: The vehicle_actor is inside the junction.

335.2.2 sut_crossing_within_junction

Ego: The Ego drives within the junction.

335.2.3 sut_finishes_crossing_junction

Ego: The Ego reaches the end of the junction.

335.3 Parameters

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

Parameter Type Description Default value
max_distance_from_junction length The distance from the Ego to the junction start 10m

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

Parameter Type Description Default value
min_offset_from_junction_start length The minimal offset from the junction start; negative values indicate positions behind the junction start -10m
min_offset_from_junction_end length The minimal offset from the junction end; negative values indicate positions behind the junction end -5m
max_offset_from_junction_end length The maximal offset from the junction end; positive values indicate positions after the junction end 5m

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

Parameter Type Description Default value
kinds list of evaluation_object_kind The possible kinds of vehicle_actor in the scenario No default value
