Patent number: 12372373Abstract: A system is disclosed for generating a storage lane marking for a map database. The system, for example, generates a candidate storage lane marking for a first topology based on: the candidate storage lane marking being (i) to the left of a leftmost through-traffic lane marking of the first topology or to the right of a rightmost through-traffic lane marking of the first topology, and (ii) on either start or end of the first topology. The system further makes a determination of whether the candidate storage lane marking is valid based on one or more of following: (i) whether one or more vehicle path locations are located within a polygon defined by (a) the candidate storage lane marking and (b) a corresponding edge of the first topology, or (ii) whether the candidate storage lane marking is located within another topology different from the first topology.Type: GrantFiled: March 21, 2022Date of Patent: July 29, 2025Assignee: HERE GLOBAL B.V.Inventor: Zhenhua Zhang
