Description
We observed a case in which the vehicle detected outside of the lanes were associated with a lanelet that is completely irrelevant, resulting in a weird predicted path generated in front of the ego-vehicle. After some investigation, we figured out that the package finds

even for such vehicles inStep 2. Search opposite directional lanelets
part.After discussing with @takayuki5168, we propose to add the distance filtering to the
Step 2
as well asStep 1
.INTERNAL LINK: https://tier4.atlassian.net/browse/RT0-29313
Tests performed
Tested in pilot-auto.x2 and confirmed that the false positive prediction path is suppressed.
Effects on system behavior
Note that this modification may produce some false negatives for some vehicles that are passing the opposite lanes (e.g. during avoidance). But we assume that this increase in false negatives is limited since the distance threshold (3.0 m) is still fairly large. If we still encounter some false positives, we may also consider changing the distance threshold only for opposite lanes (e.g. making it larger).
