1. A vehicle comprising:
a navigation device; and
a controller electrically connected to the navigation device,
wherein the controller is configured:
to determine a first speed of the vehicle based on a main line speed limit of a road on which the vehicle is traveling, wherein the main line speed limit is included in navigation information output by the navigation device,
to determine a second speed for decelerating the vehicle to a predetermined speed when the vehicle is positioned at a target point of a curved lane based on:
the predetermined speed and a predetermined allowable maximum deceleration amount in the curved lane in route information included in the navigation information; and
an arc length from a branching point of the road to the curved lane calculated based on the navigation information, and
to determine the first speed or the second speed as a control target speed of the vehicle at the branching point,
wherein, when the vehicle continues to travel on the main line of the road without entering the curved lane guided by the navigation device, the controller controls the vehicle to continue traveling at the first speed without decelerating a speed of the vehicle to the second speed.
