APPARATUS AND METHOD FOR GUIDING ROUTE UISING OF REAL-TIME TRAFFICINFORMATION

摘要

PURPOSE: Path guidance device and method thereof using real time traffic information capable of providing an optimal driving path are provided to reach a destination within the shortest time by automatically researching a path having real time traffic information reflected at an intersection point. CONSTITUTION: An estimated time of arrival calculation unit (134) calculates an estimated time of arrival using a remaining distance to a destination and velocity of a vehicle. An intersection judgment unit (133) judges whether the vehicle enters the intersection or not. An estimated time of arrival comparison unit (135) updates a path with a new path when an estimated time of arrival of the new path is smaller than the estimated time of arrival of the initial path.
