Abstract

A method and apparatus for representing a road network and a method and system for processing traffic information data using the method for representing a road network are provided. The method for processing traffic information data comprises: conversion step of converting traffic information data based on road networks of one or more types of road maps into traffic information data of intersections and sections, based on correspondence between the road networks of one or more types of road maps and the road network represented by the intersections and the sections, wherein the road network represented by the intersections and the sections is obtained by the method for representing a road network; and fusion step of fusing the converted traffic information data of intersections and sections to obtain unified traffic information data. The present invention proposes using a road network represented by intersections and sections as an intermediate model, which emphasizes the importance of intersections as hub nodes of the road network, and is compatible with various forms of map representations and universal. In this way, more accurate and comprehensive information can be obtained by fusing traffic information data from different data sources, which is advantageous for services such as traffic information prediction.
