Abstract
Method and arrangement for providing map information to an operator of a vehicle includes forming a map database to reside on the vehicle, e.g., after installation on the vehicle, and which includes for example, data about lanes that the vehicle can travel on locations of a boundary or edges of the travel lanes, data about traffic control devices in the database, data about guard rails along travel lanes and/or data about inanimate objects such as poles and trees alongside the travel lanes. The database is managed to ensure that it has current information about a travel lane on which the vehicle is currently situated. This may entail establishing wireless communications to the vehicle to enable data to be provided to the database, e.g., from other vehicles and/or from infrastructure.
