The invention discloses a traffic flow prediction system based on traffic big data. The system comprises a category identification module, a road gauge detection module, a feature extraction module and a traffic flow prediction module. The category identification module is used for detecting the category of a vehicle running on a road; the road regulation detection module is used for detecting the road driving regulation of the current vehicle location based on the traffic big data; the feature extraction module is used for extracting time sequence features influencing traffic flow prediction; and the traffic flow prediction module is used for predicting the traffic flow according to the type of the current vehicle, the road driving regulations of the location of the vehicle and the time sequence characteristics. According to the method, the relationship between the vehicle type and vehicle driving permission in different time periods is considered, so that the traffic flow of a subsequent lane can be predicted conveniently; according to the method, the traffic flow prediction model is constructed by combining the prediction model of the biphase long short-term memory BiLSTM influencing traffic flow prediction and the data of the current road condition, and the method has a good prediction effect on traffic flows in different time periods.
