PROBLEM TO BE SOLVED: To provide a traffic information providing system which can arbitrarily set a position resolution and a traffic representation resolution of traffic information and flexibly support a traffic information prediction service. SOLUTION: A traffic information providing apparatus quantizes the state quantity of traffic information changing along a road (b), converts the quantized state quantity to a value having statistical deviation (c), encodes the value (d), and provides the encoded value to a traffic information utilizing apparatus such as a car navigation system. The traffic information utilizing apparatus decodes the encoded state quantity to reproduce the traffic information on the road. COPYRIGHT: (C)2008,JPO&INPIT |
