We present a method that can detect a circular traffic signs and Light Emitting Diode (LED) traffic signs by combining fast radial symmetric transform and a proposed symmetric shape detection method. The proposed method can choose the appropriate size and sign type by computing the confidence of given image to each pre-defined signs, In a real road video that includes LED signs and circular traffic signs, our algorithm scored 94.3 % detection ratio and 0.33 false positive per frame; these results are acceptable in advanced driver assistance systems.
