The present invention relates to a vehicle, a route calculation device, and a route calculation method. If it is determined that, at a target exit (Etar) of a roundabout (300) that exists in a targetroute (Rtar), a travel restricting event (Plim) that restricts passing of a vehicle (10) through the target exit (Etar) has occurred on the basis of a peripheral travel environment detected by a peripheral environment detection unit, a route calculation device (80) of the vehicle (10) adds one circulation or a part of the circulation in the roundabout (300) to the target route (Rtar).
