ABSTRACT:
The present invention relates to a traffic information providing system and method using a traffic information collecting digital map. A traffic information collecting terminal receives GPS data from at least one GPS satellite, and generates traffic information target location information with reference to traffic information established based on the GPS data. The traffic information target location information includes a coordinate and a time and can further include a type or an order on the traffic information target location information. The traffic information providing system matches traffic information target location information provided by the terminals on nodes and links for collecting traffic information of a traffic information collecting digital map, generates section communication information for a section, processes the section communication information, and provides it as traffic information. Therefore, accurate communication information is generated and more accurate traffic information is provided. For example, it is possible to generate accurate traffic information excluding a traveling time (or a traveling speed) error caused by a probe vehicle's entrance to a rest area from the link having an expressway rest area.
