323. Ego Stopped In Lane evaluation scenario
The ego_stopped_in_lane detects cases where the Ego comes to a stop in the lane, even though the lane is clear and free of other traffic or objects.

323.1 Scenario phases
The phase descriptions are as follows:
323.1.1 ego_drive
Ego: The Ego drives at a speed of at least max_standstill_speed.
323.1.2 ego_stop
Ego: The Ego comes to a stop in the lane at a speed of at most max_standstill_speed.
323.1.3 ego_stop_while_the_lane_is_clear
Ego: The Ego stops in the lane at a speed no greater than max_standstill_speed, while the lane ahead is
clear for at least minimal_distance_of_clear_lane. A fraction of at least on_road_percentage of the Ego
is inside the road's driving lane's boundaries. The Ego is not in a junction nor at a distance of at least
minimal_offset_from_junction away from one. The scenario should last at least min_phase_duration.
323.2 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 |
|---|---|---|---|
max_standstill_speed |
speed | Maximum speed of the Ego to be considered as stopped. | 1.5mps |
minimal_offset_from_junction |
length | Minimal offset from a junction where the scenario does not occur. Should be negative. | -20m |
minimal_distance_of_clear_lane |
length | Minimal distance of clear lane, should be positive | 20m |
max_drive_phase_duration |
time | Maximal duration of the ego_drive phase |
2sec |
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 |
min_phase_duration |
time | Minimal phase duration | 0.5s |
