1. A route guidance apparatus comprising:
at least one memory storing computer-executable instructions; and
at least one processor configured to execute the computer-executable instructions to:
receive, from a communication device of a parking lot, reservation information comprising at least one of a parking-reserved space of the parking lot reserved by a user, a vehicle type, a vehicle number, or a parking time and transmit the reservation information to a communication terminal of the user;
recognize a vehicle number of a reserved vehicle by using a camera at an entrance of the parking lot and determine whether the reserved vehicle enters the parking lot or exits the parking lot;
divide each floor of the parking lot into a plurality of unit areas of a predetermined size;
determine real-time density of each of the plurality of unit areas based on a number of vehicles within the unit area;
generate an optimal parking route comprising a maximum number of a unit area whose density is determined to be low based on the calculated density;
generate an optimal exit route comprising a maximum number of a unit area whose density is determined to be low based on the calculated density;
provide the user with the optimal parking route when the reserved vehicle parks, and provide the user with the optimal exit route when the reserved vehicle exits; and
control a speed and a steering angle of the reserved vehicle based on the optimal parking route or the optimal exit route so that the reserved vehicle moves to the parking-reserved space or exits up to the entrance of the parking lot when the reserved vehicle is an autonomous vehicle.
