MAP GENERATION APPARATUS

A map generation apparatus including a microprocessor. The microprocessor is configured to perform recognizing another vehicle traveling on an opposite lane opposite to a current lane on which a subject vehicle travels, acquiring an information of an external situation around the other vehicle in a route matching section when the other vehicle is recognized, the information of the external situation being obtained by the other vehicle traveling on the opposite lane, the route matching section being a section in which a driving route of the subject vehicle and a driving route of the other vehicle match in a driving route including the current lane and the opposite lane, and generating a map for the opposite lane in the route matching section, based on the information of the external situation.
