The invention discloses a multi-fine-grained traffic flow prediction method and system for highway tunnel management and control. The method comprises the steps of collecting highway long tunnel traffic flow original data; constructing a prediction model according to the traffic flow original data; and the constructed prediction model is used to complete traffic flow prediction. According to the model, multi-source variables are sent to a multi-fine-granularity fusion prediction module for extracting multi-fine-granularity fusion features, and then the features are sent to a time-space relation feature extraction module for capturing time-space relation dependence of data samples. The method has good performance in time sequence prediction tasks, especially in multi-fine-granularity expressway long tunnel traffic flow prediction.
