Abstract
Abstract A system and method for providing an image-based traffic information are disclosed. A plurality of time-variant real entities are converted into time-variant image vector entities and the attribute-designating statement of the time-variant image vector entity is determined based on a traffic information. Also, a plurality of time-invariant real entities are converted into a plurality of time-invariant image vector entities which constitutes a basic map. A traffic information map including at least said traffic state map is transmitted to a user device via a communication network. At user device, a basic image in accordance with the basic map is displayed on a screen of the user device and a traffic state image in accordance with the traffic state map is cumulatively displayed on the basic image.
