The present invention relates to a method for calculating trip paths determined by a departure point and a target point by using traffic information in a terminal. The method includes the steps of: requesting traffic information related to a trip from a server; receiving the traffic information related to the trip from the server; and calculating the paths by using the received traffic information, wherein the received traffic information includes traffic events corresponding to information on disturbances in the traffic flow in an area or the path related to the trip, and performance parameters corresponding to information on traffic flow in a road segment within a constant radius from the departure point, and wherein the performance parameters can be received from the server in the case where there is congestion heavier than a predetermined level within a constant radius from the departure point.
