Disclosed is a control method of self-adaptive smart city intelligent traffic signals. The method comprises the following steps: 1, a road sensor processing acquired vehicle traffic flow information and generating a corresponding traffic state set and a decision set; 2, arranging a punishment and award function, a learning rate and a discount factor; 3, sending the processed traffic flow information to a Q learning device for generating a traffic decision; 4, a traffic decision sequence acting on a traffic crossing through a traffic signal controller; 5, feeding back punishment and award function values and evaluating whether the decision is good or bad; and 6, continuously sensing a next state of an environment. The control method of the self-adaptive smart city intelligent traffic signals, provided by the invention, is good in control effect, quite small in influence of a control algorithm on the environment and good in stability.
