The invention discloses a real-time adaptive signal control optimization method and system for a single-point intersection, and the method comprises the following steps: firstly, carrying out the layout of a vehicle-road cooperation environment, and collecting the leaving flow rate of vehicles at the upstream of the intersection; secondly, estimating vehicle arrival data of an entrance lane of the intersection by using a dynamic motorcade discrete model; then, according to an NEMA phase rule, constructing a global optimal signal timing GOST search algorithm in a prediction time interval; and finally, searching an optimal signal timing scheme in the predicted time interval by using a GOST optimization algorithm. According to the invention, self-adaptive signal control can be carried out on the single-point intersection in a vehicle-road cooperation environment, the queuing delay of vehicles at the intersection is reduced, and the passing efficiency of the intersection is improved.
