1. A map data output device comprising:
a map storage configured to store map data that represents lane network information that shows a model of a lane of a road by connecting a link that indicates a part of the lane;
a position determination portion configured to determine a current position of a vehicle;
a read processing portion configured to read, from the map storage, the map data of an area established based on the current position determined by the position determination portion;
a control map generation portion configured to generate control map data by adding information indicating lane shape information to the map data based on the map data read by the read processing portion; and
an output portion configured to output the control map data to a vehicle control device configured to control behavior of the vehicle, wherein:
the added information is the lane shape information and is defined as addition information;
the map data represents lane shape information that indicates a shape of a lane for each link and is different from the addition information; and
the control map generation portion is configured to generate the control map data obtained by adding the addition information to increase an information amount of the lane shape information in the read map data.
