Analysis of Traffic Accident Based on Knowledge Graph

Traffic accident data include multidimensional dynamic and static factors such as “people, vehicles, roads, environment” at the time of accident, which is one important sources for improving traffic safety environment. Based on case accidents construction idea knowledge graph, demand, modeling, extraction, storage are analyzed in detail. Finally, graph constructed. The visualization analysis carried out from four angles: portrait, classification, statistics, correlation path. visualized graphic network displayed by combines human cognition with machine cognition, improves human’s ability to understand massive complicated data. theoretical system constructing has certain reference significance follow-up research
