approaches

Indicates from which side of the road to approach a waypoint. Accepts NavigationRoute.APPROACH_UNRESTRICTED (default) or NavigationRoute.APPROACH_CURB . If set to NavigationRoute.APPROACH_UNRESTRICTED, the route can approach waypoints from either side of the road. If set to NavigationRoute.APPROACH_CURB, the route will be returned so that on arrival, the waypoint will be found on the side that corresponds with the driving_side of the region in which the returned route is located. If provided, the list of approaches must be the same length as the list of waypoints.
