Red traffic light detection using fast radial symmetry transform

Traffic light is one of the important signs for drivers that help managing the car flow and reducing accident on the road. As of today technology, there exists a traffic light detection system that warns the driver to reduce the accident significantly. In this paper, we are concerned with only the red and yellow traffic light to reduce false positive and time consumption. The fast radial symmetry transform is a fast variation of the circular Hough transform. The CIELab color model is used because it is less dependent on lighting conditions. The precision and the recall of the proposed method are increased from previous work.
