The invention provides a road intersection identification method and device, equipment and a storage medium. The road intersection identification method comprises the following steps: rasterizing data of a plurality of track points to obtain raster data; wherein the grid data comprises a brightness value of each grid in a plurality of grids arranged in rows and columns; acquiring density change characteristics of track points in each grid according to the grid data; obtaining the steering angle change characteristics of the track points in each grid; and based on the density change characteristics and the steering angle change characteristics of the track points in the target grid in the plurality of grids, identifying whether the target grid belongs to the road intersection through the trained classifier. According to the embodiment of the invention, the extraction efficiency and the extraction accuracy of the intersection can be improved.
