The invention discloses a two-phase traffic signal timing method, and relates to the technical field of intelligent traffic, and the method comprises the steps: obtaining the input parameters of two-phase traffic signal timing; the input parameters comprise a coordination period, traffic flow, a minimum value of a distance to a previous intersection, a maximum value of a two-way traffic flow difference value and a minimum value of the two-way traffic flow difference value; a fuzzy control model is constructed, a green time ratio is determined based on the fuzzy control model, and the fuzzy control model takes the input parameters as input and takes the green time ratio as output; and obtaining two-phase traffic signal timing based on the green signal ratio output by the fuzzy control model. According to the invention, an input parameter is innovatively put forward, and the distance from the previous intersection is taken as a consideration factor, so that signal timing is more synergetic, and a given timing scheme is more effective.
