The invention relates to a road element rapid identification method and device based on a mobile laser radar, and belongs to the technical field of road detection.The method comprises the steps that laser point cloud data are acquired, and non-ground point cloud data are determined according to the elevation difference between each point and a neighborhood point in the laser point cloud data; calculating a normal included angle between each point in the non-ground point cloud data and two points in a neighborhood, and performing feature clustering on the non-ground point cloud data according to the normal included angle to obtain a feature point sample set; carrying out processing and correlation analysis on the feature point sample set to obtain an average decline precision (MSE) value and a feature correlation coefficient of each feature point; and when the MSE value and the feature correlation coefficient meet a preset condition, classifying the feature point sample set to obtain an identification result o
