摘要:
A destination searching system and method is provided. The system includes: a controller; an interface; a POI (Point Of Interest) hierarchically ordering unit for extracting a trade name and a geographical name from each of a plurality of POIs, hierarchically ordering and classifying an industry type, providing a description of each category, suitable classification of each POI into a category, and storing the classified POI; a query analyzing unit for, when receiving a query for a destination search, recognizing the industry type, the geographical name, and other character strings from a character string included in the received query; and a POI selecting unit for extracting a POI candidate, and selecting a POI determined to be the closest to a destination queried by a user.
摘要:
The present invention relates to a system and a method of predicting traffic speed based on the speeds of neighboring links. A system for predicting traffic speed on a link basis, on a map based on a past traffic patterns, includes a prediction model establishment unit that establishes a neighboring link speed-based prediction model including the correlation between the speed of each link and the speeds of neighboring links based on real-time traffic information accumulated in a real-time traffic information database for a predetermined time, a prediction model database that stores the established neighboring link speed-based prediction model data, and a traffic speed prediction unit that inputs real-time neighboring link speed information for a specific object link to the neighboring link speed-based prediction model and predicts an output value according to the real-time neighboring link speed information as the traffic speed of the object link.
