METHOD FOR SUPPLYING TRAFFIC COLLECTION DATA OF TRAFFIC COLLECTION DATA SUPPLYING SYSTEM

摘要

The method for providing traffic collection data of a traffic collection data providing system including a data providing server and a metadata catalog system of the present invention includes the steps of collecting and storing the traffic collection data in the form of raw data in a storage device of a first server, the meta data catalog system comprising the steps of: Traffic collection data stored in the first server by a data catalog system to classify classes and objects into a hierarchical structure using a data classification system, and to define a relationship between the class and the objects or between the objects constructing a metadata graph database, querying, by the data providing server, the requested metadata to the metadata catalog system, when metadata for specific traffic data is requested through a web interface, and the metadata providing the traffic metadata graph database provided from a catalog system through the web interface as a data map visually schematic, wherein the classes include roads, intersections, vehicles, and public transport, and the objects are collected It is subdivided into RSE, CCTV, VDS, DTG, lidar/radar, and GPS according to equipment, and the traffic collection data includes speed, traffic volume, Intelligent Transport Systems (ITS)/Bus Information System (BIS) table, node-link information , road information, detector-link relationship, bus route information, and a base and master table including bus stop information, and a code table including road grade, road type, node type, and region.
