Adaptive control method and system for variable lane of traffic signal controller

The invention discloses an adaptive control method and system for a variable lane of a traffic signal controller, and the method comprises the following steps: S100, reading a variable lane switching configuration file set by a scheme configuration person, obtaining the configuration parameter information in the file, and obtaining a control scheme number of the variable lane which is being released; step S200, acquiring multiple pieces of queuing length data of different lanes in continuous time required in the judgment information table; s300, processing the data according to a judgment rule, and calculating to obtain multiple pieces of judgment information; s400, the judgment information is processed according to the output rule, and whether control scheme switching is carried out or not is judged; according to real-time road vehicle queuing length information, release of the intersection variable lane scheme can be controlled in real time, the problem of traffic jam is solved, the real-time performance is
