Abstract: Traffic sign detection and recognition is an essential component of advanced driver assistance systems. It is mainly designed to increase driver safety through the fast acquisition and interpretation of traffic signs. However, still such systems are not able to recognize traffic signs accurately. In this article, firstly challenges and undesirable factors facing road traffic sign detection and recognition systems are addressed. The contributions of recent works to the various stages inherent in traffic sign detection: segmentation, feature extraction, and final sign detection are described in this paper.

Keywords: Active safety, object detection, recognition.
