This system which sets PLC as the core of intellectual traffic controller is easy, flexible to program and is highly reliable. Applications and practices have proved that with this system, the fuzzy controller could effectively decrease the average vehicle delay in isolated intersection, therefore, has proposed a novel method to realize the intellectual control of traffic systems. Key Words: PLC; fuzzy control,;average vehicle delay 1銆佸紩瑷€ 銆€銆€鍩庡競浜ら€氱郴绲�(t菕ng)鏄竴鍊嬪叿鏈夐毃姗�(j墨)鎬�銆佹ā绯婃€у拰涓嶇⒑瀹氭€х殑寰�(f霉)闆滅郴绲�(t菕ng)锛屽鏋滈€氶亷寤虹珛涓€鍊嬫暩(sh霉)瀛�(xu茅)妯″瀷渚嗗弽鏄犲闅涘柈璺彛浜ら€氱媭娉佹槸闈炲父鍥伴洠鐨勩€傝€岄噰鐢ㄦā绯婃帶鍒舵柟娉曡ō(sh猫)瑷堜氦閫氱噲鎺у埗绯荤当(t菕ng)锛屽彲浠ュ缓绔嬬簿纰虹殑鏁�(sh霉)瀛�(xu茅)妯″瀷锛屾笡灏戣矾鍙ｅ欢瑾ゆ檪闁撳拰鍋滆粖娆℃暩(sh霉)锛屾洿鍔犵簿纰哄湴鎺у埗闈炵窔鎬х殑銆侀毃姗�(j墨)鐨勫崄瀛楄矾鍙ｈ粖娴侀噺锛屾サ澶ф彁楂樿矾鍙ｇ殑閫氳鑳藉姏銆傛湰鏂囧皣宸ユキ(y猫)涓婃噳(y墨ng)鐢ㄦ瘮杓冩垚鐔熺殑鍙法绋嬫帶鍒跺櫒锛圥LC锛夌敤浜庡皪鍠矾鍙ｄ氦閫氫俊铏熺噲瀵︾従(xi脿n)杌婅紱绛夊緟闀峰害鐨勬ā绯婃帶鍒舵柟娉�銆� 瑭虫儏璜嬮粸鎿婏細鍩轰簬PLC鐨勪氦鍙夊彛浜ら€氱噲鐨勬ā绯婃帶鍒�
