The invention discloses an airport departure layer lane traffic control decision method and system based on a fuzzy cellular automaton. The method comprises the following steps: constructing a fuzzy cellular automaton model suitable for an airport departure layer lane; collecting historical traffic flow data of an airport departure layer lane; performing time-phased prediction on future traffic flow based on historical traffic flow data of airport departure layer lanes by using a long-short-term memory neural network; based on the predicted traffic flow, the fuzzy cellular automaton model is used for carrying out safety index evaluation on an airport departure layer lane, and whether traffic signal control needs to be started or not is determined; and if traffic signal control is needed, determining optimal signal timing based on a traffic delay index obtained by simulation. The invention aims to optimize the passenger-vehicle mixed traffic flow of the airport departure layer lane and improve the traffic efficiency and safety.
