The invention discloses a traffic control field knowledge graph construction method and device based on a unified road network. The method comprises the steps of obtaining data of multiple data sources in a traffic control field; acquiring data of multiple data sources, determining multiple categories of entities based on the data of the multiple data sources, constructing a unified road network based on basic data in the data of the multiple data sources, setting region classification and road network classification on the unified road network, filling the multiple categories of entities and index data and labels of the various entities into the unified road network, obtaining a mode layer of the knowledge graph of the traffic management field; and writing the data of the multiple data sources into a mode layer of the knowledge graph of the traffic management field to obtain the knowledge graph of the traffic management field. By analyzing the entities and relationships in the traffic control field, the hierarchical road network, the index data and the labels are fused, the knowledge graph in the traffic control field is automatically constructed, the construction efficiency of the knowledge graph can be improved, and the labor cost can be reduced.
