Abstract
Abstract A method is provided for managing map data for intersections having stop sign indicators. A request is initiated for turn-by-turn navigation instructions for a destination from a vehicle to an infrastructure. A turn-by-turn navigation maplet is transmitted from the infrastructure to the vehicle. A geographical region associated with the received turn-by-turn navigation maplet is identified. A determination is made whether stop sign locations already retained within a memory of the vehicle relate to the identified geographical region. The vehicle on-board device requests stop sign maplets for the identified geographical regions from the infrastructure if the stop sign locations retained within the memory of the vehicle do not relate to the identified geographical region. The stop sign maplets are transmitted for the identified geographical region from the infrastructure to the vehicle. The stop sign maplets relate to stop sign intersection data within the identified geographical region.
