The invention discloses a traffic flow-based traffic signal lamp intelligent control system and a traffic flow-based traffic signal lamp intelligent control method. The method comprises the following steps: firstly, arranging traffic flow data at a plurality of preset time points into traffic flow time sequence input vectors, and then carrying out local time sequence feature analysis to obtain a sequence of traffic flow local time sequence feature vectors; carrying out traffic flow time sequence fluctuation semantic measurement on every two adjacent traffic flow local time sequence feature vectors to obtain a traffic flow time sequence fluctuation semantic feature vector, then cascading sequences of the traffic flow local time sequence feature vectors to obtain a traffic flow full time domain semantic feature vector, and finally obtaining a traffic flow full time domain semantic feature vector; and processing the traffic flow full-time domain semantic feature vector and the traffic flow time sequence fluctuation semantic feature vector by using a projection layer to obtain a traffic flow time sequence multi-dimensional semantic feature, and finally, based on the traffic flow time sequence multi-dimensional semantic feature, determining a recommended signal lamp duration. Therefore, the traffic efficiency and the safety can be improved.
