Abstract

A method of recognizing a intersecting point in a navigation system includes a first step of extracting road type information from a road DB if it is determined as a intersecting point in a map DB, a second step of extracting road width information and traffic lane information depending on the extracted road type from the road DB, a third step of extracting GPS error information and map error information from a memory, and a fourth step of calculating the size of the intersecting point based on the extracted GPS error information, map error information, road width information and traffic lane information and recognizing a intersecting point. Therefore, an intersecting point can be recognized as a section, but not a point. Accordingly, there is an advantage in that smooth rotation can be induced at an intersecting point when a vehicle is navigated. Furthermore, when section traffic information is collected employing navigation using GPS, there is an advantage that a transit time between intersecting points can be calculated.
