Abstract
Disclosed is a navigation system for providing real-time traffic information to users connected thereto through a communication network and a traffic information processing method by such a system. The processing method for using real-time traffic information for calculating a travel route in a navigation system according to the present invention includes the step of receiving acquired traffic information and creating traffic information based on first map data. The processing method also includes the steps of converting the created traffic information into a second map data format different from a first map data format, and causing the format-converted traffic information to be reflected in the second map data and thus enabling an optimal travel route, based on the second map data in which the acquired traffic information is reflected, to be calculated when the travel route is requested.
