Spatial Knowledge Graph for Analyzing Traffic Accident Data

Abstract

Various attempts are being made to effectively manage and utilize the considerable amount of traffic accident data generated in real-time. A knowledge graph, which organically integrates different contexts based on their relations using graph structures, is a good alternative for managing accident data. This study proposes a traffic accident spatial knowledge graph (TA-SKG) that integrates road-level spatial context to manage detailed traffic accident information. Additionally, a test graph was constructed using emergency response activity data and road networks, and several use-cases for TA-SKG were presented.
