352. Narrow Oncoming NPC Lateral Incursion evaluation scenario
In the narrow_oncoming_npc_lateral_incursion evaluation scenario, the vehicle_actor and the Ego are approaching each other from opposite driving directions. The vehicle_actor veers into the Ego's path in the oncoming lane.

352.1 Actors
The actors associated with this scenario are as follows:
| Actor | Description | Type | Depiction |
|---|---|---|---|
ego |
Vehicle under test | vehicle |
![]() |
vehicle_actor |
Oncoming vehicle | vehicle |
![]() |
352.2 Scenario phases
The phase descriptions are as follows:
352.2.1 veering_phase
Ego: The Ego drives in the oncoming lane.
vehicle_actor: The vehicle_actor drives in the outgoing lane, to the left of the Ego, keeping a maximum distance of
max_distance_from_ego from the Ego and veers into the oncoming lane, with at least
veer_from_lane_threshold of the vehicle_actor entering the Ego's lane.
352.2.2 oncoming_phase
Ego: The Ego drives in the oncoming lane.
vehicle_actor: The vehicle_actor keeps driving in the outgoing lane, keeping a maximum distance of
max_distance_from_ego from the Ego.
352.3 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 |
|---|---|---|---|
min_distance_from_ego |
length | Minimal geometric distance from the Ego to the oncoming vehicle during the entire scenario | 0m |
max_distance_from_ego |
length | Maximal geometric distance from the Ego to the oncoming vehicle during the entire scenario | 80m |
min_veering_phase_duration |
time | The minimal duration of the veering_phase phase |
0.5s |
max_oncoming_phase_duration |
time | The maximal duration of the oncoming_phase phase |
8s |
veer_from_lane_threshold |
float | The threshold at which the vehicle veers from its lane into the oncoming lane. Should be a float number from 0 to 1 representing the portion of the vehicle that veers. A veer_threshold of 0.5 means that at least half of the vehicle's width must be outside the lane. | 0.1 |
