VERTICAL ORDER DETERMINATION FOR OVERLAPPING ROADWAYS

Systems, methods, and other embodiments described herein relate to determining a vertical order of overlapping road segments. In one embodiment, a method includes generating connections between centroids based on at least an elevation difference, proximity, and forming a non-self-overlapping polygon. The centroids are vehicle positions along one or more roads. The non-self-overlapping polygon has sides that match at least a portion of the one or more roads and do not overlap. The method includes determining a vertical order of the one or more roads based on at least the non-self-overlapping polygon and an indicator indicating an elevation of the non-self-overlapping polygon.
