338. NPC yield to SUT evaluation scenario
In the npc_yield_to_sut evaluation scenario, the vehicle_actor gives the right of way to the Ego that comes from a different junction entry and then crosses the junction. The junction may have road markings or signs, but does not have traffic lights.

338.1 Actors
The actors associated with this scenario are as follows:
| Actor | Description | Type | Depiction |
|---|---|---|---|
ego |
Vehicle under test | vehicle |
![]() |
vehicle_actor |
Vehicle actor | vehicle |
![]() |
338.2 Scenario phases
The phase descriptions are as follows:
338.2.1 car1_stop_and_give_the_right_of_way
Ego: The Ego is within the junction, and the vehicle actor, located at the same junction and coming from a different junction entry, gives the right of way to the Ego.
vehicle_actor: The vehicle_actor stops near the same junction as the Ego, 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.
338.2.2 sut_finishes_crossing_junction
Ego: The Ego drives within the junction and by the end of the phase is positioned between min_offset_from_junction_end and max_offset_from_junction_end
from the junction end.
vehicle_actor: The vehicle_actor gives the right of way to the Ego, while remaining outside the range of
min_offset_from_junction_end and max_offset_from_junction_end from the junction end.
