Adaptive Traffic Signals Control by Using Fuzzy Logic

In order to improve efficiency of control strategy about traffic signal timing in single intersection, in this paper, a reckoning model about traffic signal control strategy is proposed. This model is built according to the number of delayed vehicles in one unit time, and an improved FLC (fuzzy logic controller) is designed, this controller´s values of initial parameter are established according to historical traffic flows, who can adjusts the parameters of standardization according to the reckoning model, and produces an optimal control strategy. Experimental results demonstrate this method is effective.
