157. SUT yield to NPC with crossing paths evaluation scenario

In the sut_yield_to_npc_with_crossing_paths evaluation scenario, the Ego yields to the NPC from a different junction entry, with a shared area between their paths inside the junction.

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

157.1 Actors

The actors associated with this scenario are as follows:

Actor Description Type Depiction
ego Vehicle under test vehicle
vehicle_actor Vehicle actor vehicle
Phase 1: Ego yield to NPC with crossing paths
Phase 2: Ego yield to NPC with crossing paths
Phase 3: Ego yield to NPC with crossing paths
Phase 4: Ego yield to NPC with crossing paths

157.2 Scenario phases

The phase descriptions are as follows:

157.2.1 sut_stops_and_gives_the_right_of_way

Ego: The Ego stops near the same junction as the vehicle_actor, positioned between min_offset_from_junction_start and max_offset_from_junction_start from the junction start and gives the right of way to the vehicle_actor. Its speed ranges from 0 kph up to stopping_car_speed_limit, and it is outside the no_traffic_light_ahead_distance from any traffic light.

vehicle_actor: The vehicle_actor is within the junction. The Ego has entered the same junction and comes from a different junction entry. The vehicle_actor has not yet entered the shared area where its path intersects with the Ego's path inside the junction.

157.2.2 npc_in_encroachment_area_and_sut_yields

Ego: The Ego has not yet entered the shared area where its path intersects with the vehicle_actor's path inside the junction.

vehicle_actor: The vehicle_actor is in the shared area where its path intersects with the Ego's path inside the junction.

157.2.3 encroachment_area_is_clear

Ego: The Ego has not yet entered the shared area where its path intersects with the vehicle_actor's path inside the junction.

vehicle_actor: The vehicle_actor has finished crossing the shared area where its path intersects with the Ego's path inside the junction.

157.2.4 sut_in_encroachment_area

Ego: The Ego is in the shared area where its path intersects with the vehicle_actor's path inside the junction.

157.3 Configuration parameters

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

Parameter Type Unit Description Default value
no_traffic_light_ahead_distance length m Forward distance within which no traffic lights should be detected ahead of the vehicle_actor 20m
[Click] The input items inherited from the sut.logiq_crossing_path_scenario scenario are as follows:
Parameter Type Unit Description Default value
encroachment_start_buffer float 5 Specify a part from the beginning of the encroachment area that will be excluded from it (i.e. in this area, the modifier will still return false). For example: start_buffer 0.25 means only the last 75% of the encroachment will be considered as part of the encroachment 0.25
encroachment_end_buffer float 5 Specify a part from the end of the the encroachment area that will be excluded from it(i.e. in this area, the modifier will still return false). For example: end_buffer 0.25 means only the first 75% of the encroachment will be considered as part of the encroachment 0.25
[Click] The input items inherited from the sut.logiq_yield_scenario scenario are as follows:
Parameter Type Unit Description Default value
max_offset_from_junction_start length m Maximum distance from an actor to the junction start 10m
ref_car_max_distance_from_junction length m Maximum distance (in length units) from the junction for the reference vehicle to be considered inside the junction 10m
stopping_car_speed_limit speed kph Maximum speed of an actor to be considered as stopped 2kph
[Click] The input items inherited from the sut.logiq_sut_and_npc_in_junction_scenario scenario are as follows:
Parameter Type Unit Description Default value
min_offset_from_junction_start length m Minimum offset from the junction start; negative values indicate positions behind the junction start -10m
min_offset_from_junction_end length m Minimum offset from the junction end; negative values indicate positions behind the junction end -5m
max_offset_from_junction_end length m Maximum offset from the junction end; positive values indicate positions after the junction end 5m

157.6 Usage

Import the post-match scenario top file and register the matcher in a match: block, overriding only the parameters you need. Any omitted parameters use the defaults listed in Configuration parameters.

The matcher is also available through the shared post-match import bundle:

  • $FTX/logiq/customers/base/osc/post_match_scenarios.osc
  • $FTX/evaluate/library/scenarios/scenario_library_post_match.osc (evaluation builds).
