The invention requests to protect a single-point intersection vehicle scheduling system and method based on adaptive signal lamps, and the method comprises the steps: predicting the traffic flow information of each lane based on a short-time traffic flow prediction algorithm, building a lane-level priority queue, verifying and determining the passing phase and phase sequence based on a combined mutual exclusion model, then, taking average delay and average parking times of a single intersection as a multi-objective function, adopting a particle swarm algorithm and a tabu search algorithm to carry out periodic signal timing optimization, distributing a corresponding green light time slice according to the traffic flow of each phase, and establishing a phase priority passing right fuzzy controller of the single-point intersection; and finally, further signal timing optimization is carried out according to the real-time traffic condition. According to the invention, all the modules supplement each other to form a perfect vehicle scheduling system and method of the self-adaptive signal lamp. The traffic efficiency of a single-point intersection and the comfort of a driver can be effectively improved.
