The invention belongs to the field of fuzzy control, and particularly relates to a single intersection traffic signal fuzzy controller which comprises a knowledge base (A*oR), a fuzzy inference engine (oR), quantification factors (Kx, Ky and Kt), a fuzzy input module (D/F) and a clearness output module (F/D), two-input signals are traffic flows x1 and y1 in an annular coil vehicle detector acquisition road network, a single-output single is real-time phase green light extension time u, the traffic flows x1 and y1 are converted into fuzzy input variables X and Y through the fuzzy input module (D/F), the fuzzy input variables X and Y are inputted to the fuzzy inference engine (oR) and ratiocinated and analyzed by the aid of the knowledge base (A*oR) to obtain a fuzzy control green light extension time output variable U, and the real-time phase green light extension time u can be acquired through the clearness output module (F/D). Current phase traffic flow information can be fuzzily controlled, a green light signal is delayed when the traffic flow is large, so that the traffic flow is evacuated, and smooth traffic is realized.
