-In the second step, we calculate the lanelets followed by the ego trajectory.
-We select all lanelets crossed by the trajectory linestring (sequence of trajectory points), as well as their preceding lanelets.
+In the second step, we calculate the lanelets where collisions should be avoided.

+Next, for each trajectory point, we create the corresponding out of lane areas by intersection the other lanelets (from step 2) with the trajectory point footprint (from step 1).
 Each area is associated with the lanelets overlapped by the area and with the corresponding ego trajectory point.
