The invention provides a latent congested road intersection prediction method and device, relating to the intelligent traffic field, and can conveniently, accurately, rapidly, reliably and stably predict road intersections having a higher possibility of congestion with low cost. The method comprises: generating SHP data of roads and intersections of an object area; based on the SHP data, using road segments as peaks, and topological nodes as connecting sides to form a road network topological dual graph representing the connection relation among road segments; based on the road network topological dual graph, performing community-based agglomeration on the road segments to obtain a plurality of communities; and assessing the entropy of intersections in a community greater than a filtering threshold, and determining latent congested road intersections based on assessed entropy. The latent congested road intersection prediction method and device are suitable for conveniently, accurately and rapidly predict congestion of road intersections.
