Navigation system for providing real-time traffic information and traffic information processing method by the same
DCFirst Claim
1. A method for using real-time traffic information for calculating a travel route in a navigation system comprising the steps of:
- receiving acquired traffic information and creating real-time traffic information based on first map data using the acquired traffic information;
converting the created real-time traffic information into a second map data format different from a first map data format;
reflecting the converted real-time traffic information to second map data; and
calculating an optimal travel route based on the second map data in which the converted real-time traffic information is reflected.

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.

2. A navigation server system for providing navigation functions to users connected thereto through a communication network comprising:
-
a traffic information server for acquiring traffic information, producing real-time traffic information based on first map data using the acquired traffic information and converting the real-time traffic information into a second map data format different from a first map data format; and
a route calculation server for reflecting the converted real-time traffic information to second map data stored in a database of the route calculation server, calculating an optimal travel route based and the second map data, and providing the optimal travel route to a subscriber when the subscriber requests the travel route. - View Dependent Claims (3, 4, 5, 6, 7)
