The invention discloses a road abnormal event detection and early warning method and system based on unsupervised lifelong learning. The method comprises the following steps: acquiring traffic scene data by using various sensors along a road and at a vehicle end, and preprocessing the traffic scene data; performing unsupervised feature extraction on the image data by using an auto-encoder, and performing feature dimension reduction on non-image data by using a principal component analysis method to extract main features; an anomaly detection model is initialized, a K-Means clustering algorithm is adopted to divide the feature space into clusters, and a normal cluster set of an initial normal traffic mode is formed; receiving new traffic data, and continuously performing online learning and updating on the model by adopting an incremental learning method, a density-based clustering algorithm and an elastic weight integration method; newly collected data are input into the updated model for anomaly detection and road anomaly event alarm; according to the method, efficient and accurate detection and timely early warning of road abnormal events are realized through unsupervised feature extraction, model initialization, lifelong learning and a model updating mechanism.
