The invention provides a variable lane control method based on adaptive time sequence segmentation, and relates to the technical field of traffic control. The method comprises the following steps: acquiring historical traffic flow data of intersections covering various date states; carrying out adaptive time sequence segmentation, delimiting a plurality of application time periods, and generating a corresponding initial static lane scheme; accessing real-time traffic flow data, performing time granularity analysis, and predicting predicted traffic flow data of the next time granularity; and performing state analysis, state switching and function change processing of the variable lane according to the current static lane scheme and the predicted traffic flow data. According to the method, time-varying characteristics of historical traffic flow data can be analyzed, a self-adaptive time sequence segmentation method is used, a plurality of application time periods are divided for working days, non-working days and holidays, and a static lane scheme is generated, so that the switching frequency of lane functions is effectively reduced while the high matching degree of the time-varying traffic flow is ensured, and the traffic flow switching efficiency is improved. And the stability of the traffic flow at the intersection is improved.
