IsolineSideOfStreetOptions

The [longitude, latitude] coordinates of the point that should be matched to a specific side of the street.

Controls whether side-of-street matching is applied to any street (AnyStreet) or only to divided roads (DividedStreetOnly). This is important when the exact side of the street matters - for example, if a building entrance is only accessible from one side of a divided highway, or if a parking lot can only be entered from northbound lanes. Without correct side-of-street matching, travel time estimates may be inaccurate because they don't account for necessary U-turns or detours to reach the correct side.
