    Abstract: The present disclosure relates to a method and apparatus for performing multipath search. The method according to an embodiment of the present disclosure may calculate a distance between an origin point and a destination point in a group of destination points. In addition, the method may generate a travel path between the origin point and the destination point using a first path-finding method when the distance between the destination point and the origin point is less than a threshold value, and generate the travel path between the origin point and the destination point using a second path-finding method when the distance between the destination point and the origin point is greater than or equal to the threshold value.

    Abstract: Disclosed are a method of generating a circular traveling route of a vehicle, a device for generating a circular traveling route of a vehicle, and a recording medium in which a program for executing the method of generating a circular traveling route of a vehicle. The present disclosure is implemented through a process of receiving a request for generating a circular traveling route including information about a list of roads to be circulated, information about the number of repeated travels on the roads to be circulated, information about a preferred traveling direction at a road branch point, and information about a travelable time of the vehicle, grouping the list of roads to be circulated into a plurality of groups, determining a vehicle traveling sequence in the plurality of groups, and generating the circular traveling route of the vehicle on the basis of a vehicle traveling sequence in the determined plurality of groups, the information about the number of repeated travels on the roads to be circulated, and the information about the travelable time of the vehicle, by a route generation device. According to the present disclosure, an optimal circular traveling route for a vehicle, which needs to travel through the entire list of predetermined roads for a specific purpose, such as building a road map, obtaining image data, or performing road maintenance work, may be efficiently generated. In addition, according to the present disclosure, an optimal circular traveling route for a vehicle, which needs to repeatedly travel a list of predetermined roads a certain number of times depending on the purpose of vehicle travel, may be generated.

    Abstract: A method of generating traffic flow statistical data by using wiper motion information of a vehicle, a method of calculating an estimated time of arrival, by using the traffic flow statistical data generated using the wiper motion information of the vehicle, and a management server used therein are provided. The present disclosure is implemented as the management server receives, from a vehicle, vehicle driving information including location information of the vehicle which is driving on a road and wiper motion information of the vehicle, and generates traffic flow statistical data of the road on which the vehicle is driving, based on the vehicle driving information. According to the present disclosure, traffic flow statistical data including weather information in units of roads may be obtained by generating traffic flow statistical data by using vehicle driving information including wiper motion information of a vehicle driving on a road. In addition, according to the present disclosure, an estimated time of arrival may be calculated based on traffic flow statistical data including weather information in units of roads, and thus, the estimated time of arrival that is calculated with very high accuracy, by considering the weather conditions of a road may be provided to a driver.
