1. A route guiding device comprising:
a communication circuit; and
a processor,
wherein the processor is configured to:
identify a first lane where a moving body is located from among lanes of a first road where the moving body is located, wherein the first road is included in roads at an intersection adjacent to the moving body,
identify a second road, included in the roads at the intersection, extended from the first road based on information on a destination of the moving body,
identify an angle between a direction of the first road and a direction of the second road identified for the moving body,
display information for notifying that a lane of the moving body is changed from the first lane to a second lane from among the lanes, in case that the angle is within a first range based on a position where the first road and the second road are connected, and
display information for notifying that the lane of the moving body is changed from the first lane to a third lane from among the lanes, in case that the angle is within a second range different from the first range based on the position where the first road and the second road are connected,
wherein a movable direction of the moving body in the second lane of the first road is different from a movable direction of the moving body in the third lane of the first road.
