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

351.1 Actors
The actors associated with this scenario are as follows:
| Actor | Description | Type | Depiction |
|---|---|---|---|
ego |
Vehicle under test | vehicle |
 |
vehicle_actor |
Oncoming vehicle | vehicle |

351.2 Scenario phases
The phase descriptions are as follows:
351.2.1 oncoming_phase
Ego: The Ego starts driving in the outgoing lane and veers into the oncoming lane with at least
veer_from_lane_threshold and enters the path of the vehicle_actor.
vehicle_actor: The vehicle_actor drives in the oncoming lane and stays at a
distance of at least max_distance_from_ego from the Ego. on_road_percentage of the vehicle_actor's bounding-box must be within the road's boundaries.
351.3 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_oncoming_phase_duration |
time | The minimal duration of the oncoming_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 Ego veers from its lane into the oncoming lane. Should be a float number from 0 to 1 representing the portion of the Ego that veers. A veer_threshold of 0.5 means that at least half of the vehicle's width must be outside the lane. | 0 |
on_road_percentage |
float | The minimal required percentage of the Ego's bounding-box to be within the road's boundaries. Should be between 0 and 1 | 0.6 |
