Traversable

Traversable refers to surfaces which may be traversed, or traveled across. This is most often used in the context of discussing raised or lowered islands located in the middle of a road or to a median separating two roadways. If an island is sufficiently above or below the surrounding road so that it is difficult for a vehicle to travel across the island, then it is considered to be non-traversable.
