140.1 Scenario phases
The phase descriptions are as follows:
140.1.1 sut_laterally_encroach_in_lane
Ego: The Ego stays in the same lane at a maximum distance of max_lateral_distance from the vehicle_actor and drives at a lateral speed of at least min_lateral_speed.
vehicle_actor: The vehicle_actor drives in the same lane as the Ego, on the npc_relative_side_to_ego side of the Ego, with a longitudinal distance between a minimum of min_longitudinal_distance and a maximum of max_longitudinal_distance.
140.1.2 sut_near_npc_in_same_lane
Ego: The Ego stays in the same lane, keeping a maximum of max_lateral_distance from the vehicle_actor
vehicle_actor: The vehicle_actor drives in the same lane as the Ego, on the npc_relative_side_to_ego side
of the Ego, with a longitudinal distance between a minimum of min_longitudinal_distance and a maximum of max_longitudinal_distance.
140.2 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 |
|---|---|---|---|---|
npc_relative_side_to_ego |
av_side | — | Side of the NPC relative to the Ego during the scenario (left or right) | Required |
min_lateral_speed |
speed | mps | Minimum lateral speed of the Ego during the sut_laterally_encroach_in_lane phase |
0.15 mps |
max_lateral_distance |
length | m | Maximum lateral distance between the Ego and the NPC during the entire scenario | 5m |
min_longitudinal_distance |
length | m | Minimum longitudinal distance between the Ego and the NPC during the entire scenario | -5m |
max_longitudinal_distance |
length | m | Maximum longitudinal distance between the Ego and the NPC during the entire scenario | 5m |

140.5 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).
import "$FTX/logiq/scenario_library_post_match/adjacent_vehicles/ego_laterally_encroach_in_lane/ego_laterally_encroach_in_lane_top.osc"
# The following example imports the top file and overrides six parameters:
match:
ego_laterally_encroach_in_lane: sut.ego_laterally_encroach_in_lane(npc_relative_side_to_ego: left,
min_lateral_speed: 0.15mps,
max_lateral_distance: 5m,
min_longitudinal_distance: -5m,
max_longitudinal_distance: 5m,
kinds: [vehicle, cyclist, truck, emergency_vehicle, bus, motorcycle])
