156. SUT yield to NPC evaluation scenario

In the sut_yield_to_npc evaluation scenario, the Ego gives the right of way to the vehicle_actor that comes from a different road and then crosses the junction.

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

156.1 Actors

The actors associated with this scenario are as follows:

Actor	Description	Type	Depiction
`ego`	Vehicle under test	`vehicle`
`vehicle_actor`	Vehicle actor	`vehicle`

156.2 Scenario phases

The phase descriptions are as follows:

156.2.1 `sut_stop_and_give_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. 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, and gives the right of way to the vehicle_actor.

156.2.2 `other_car_finishes_crossing_junction`

Ego: The Ego gives the right of way to the vehicle_actor, while remaining outside the range of min_offset_from_junction_end and max_offset_from_junction_end from the junction end.

vehicle_actor: The vehicle_actor drives within the junction, and at the end of the phase is positioned between min_offset_from_junction_end and max_offset_from_junction_end from the junction end.

156.6 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).
