Description

technical field [0001] The invention relates to the technical field of deep learning, in particular to a multi-dimensional analysis method of traffic congestion degree based on deep learning. Background technique [0002] In recent years, with the continuous advancement of urbanization and development, the number of automobiles has continued to increase, which brings convenience to transportation, but also makes traffic congestion, traffic accidents and other problems increasingly prominent. Among them, traffic congestion will not only affect people's travel efficiency, but will even lead to serious traffic accidents, endangering people's travel safety. Therefore, it is particularly important to accurately detect and analyze the degree of traffic congestion in real time. [0003] The most direct method of traffic congestion detection is to observe the road congestion on the surveillance video, but it is impossible to observe the situation of all road sections for 24 hours a...
