The invention provides a traffic flow data processing method and system based on a chaotic time sequence and chaos optimization. The method comprises the following steps: S1, constructing a chaotic time sequence by using a Lorenz system; s2, taking the chaotic time sequence as input data of an ACLSTM algorithm, and training the input data to obtain an ACLSTM model; s3, performing chaos optimization on the ACLSTM model by using a chaos optimization algorithm of Logistic mapping to obtain a trained ACLSTM model; and S4, processing the traffic flow data by using the trained ACLSTM model to obtain traffic flow data information. According to the method, the chaotic time sequence is constructed by using the Lorenz system, so that the ACLSTM model can capture the nonlinear trend of the data, the influence of an abnormal value on prediction is reduced, and the prediction performance of the ACLSTM model is improved.
