Abstract
A road network is described using roads, intersections and sections as traffic information elements and a correspondence between these elements and a road topological network in a digital map is established, so that a universal traffic information describing model, which is compatible with language used in people's daily life, can be established. The traffic information element knowledge base is generated based on roads, intersections and sections, respective attributes and the relationship between them, to support inter-conversion between road topological network traffic information and text-based traffic information. With the universal traffic information describing model and the traffic information element knowledge base, fusion and conversion of traffic data from various sources and to support various forms of presentation and interaction for traffic information, such as presentation of traffic information on digital navigation map, textual description of traffic information, map presentation of traffic information for urban trunk roads, etc. can be supported.
