Abstract: A traffic sign identification method using a traffic sign identification system includes: operating a traffic sign image capture unit to capture a road condition image, operating a traffic sign image recognition unit to pick up a traffic sign image from the road condition image, and operating an arithmetic processing unit to convert the original RGB color space of the traffic sign image into a HIS color space, and then to extract one or multiple graphical features from the HIS color space subject to a predetermined graphic pattern, and then to execute a positioning procedure to allocate one traffic sign in the traffic sign image so as to further obtain a digital speed limit image using a matching arithmetic, and then to convert digital speed limit image into a digital speed limit skeleton diagram for identification of the speed limit value of the traffic sign image.
