The invention discloses an urban traffic signal control method based on accelerated iterative learning control, and the method is characterized in that the method comprises the following steps: 1), building a traffic flow model based on iterative learning control; step 2), creating a historical iteration information database for establishing and training a random forest regression model; 3) in the iteration process of the traffic flow model based on iterative learning control, performing online optimization on the learning gain of the iterative learning control by using a particle swarm algorithm; and step 4), storing the iteration data which meets the condition and is based on the iterative learning control traffic flow model into a historical iteration information data set, and continuing to perfect the historical iteration information data set. According to the method, the problems of low convergence speed and low historical data utilization rate of an iterative learning control algorithm applied to urban traffic signal control at present are solved.
