1. A vehicle system for determining a recommended lane for an own vehicle in a case where the own vehicle travels on a road having a plurality of lanes on one lateral side thereof, the vehicle system comprising:
a controller configured to communicate with a map server that stores map information including road structure information and traffic information, the traffic information including current traffic state information on each lane and/or a statistic of a past traffic state of each lane; and
a vehicle position acquiring device configured to acquire own vehicle position information for determining the lane in which the own vehicle is traveling and transmit the own vehicle position information to the controller,
wherein the controller includes:
a vehicle position determining unit configured to determine the lane in which the own vehicle is traveling based on the own vehicle position information; and
a recommended lane determining unit configured to determine the recommended lane, and
the recommended lane determining unit is configured to
set a priority of each lane based on the map information, and
determine the lane having a highest priority as the recommended lane,
wherein when switching the recommended lane to a branching connection lane connected to a branching route so as to guide the own vehicle to the branching route, the recommended lane determining unit sets the switching point for switching the recommended lane to the branching connection lane more rearward in a vehicle travel direction in a case where determining based on the road structure information that the recommended lane curves as compared with a case where determining that the recommended lane is straight.
