TRAVEL CONTROL APPARATUS, VEHICLE, TRAVEL CONTROL METHOD, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM

There is provided a travel control apparatus. A control unit controls a position of the self-vehicle in a width direction so as to ensure a first predetermined interval between the self-vehicle and the other vehicle and to ensure a second predetermined interval between the self-vehicle and the boundary of the first lane. In a case in which both the first predetermined interval and the second predetermined interval cannot be ensured, the control unit controls the position of the self-vehicle in the width direction to preferentially ensure the first predetermined interval when the other vehicle has crossed a first boundary between the first lane and the second lane and to preferentially ensure the second predetermined interval when the other vehicle has not crossed the first boundary.
