Have you tried the Computer Vision System Toolbox?

Look at this site: http://www.visionbib.com/bibliography/contentsactive.html#Active%20Vision,%20Camera%20Calibration,%20Mobile%20Robots,%20Navigation,%20Road%20Following
particularly this section: "15.3.3.7 Road Signs, Traffic Signs, Objects along the Road, Inspections"
It should have some good algorithms that you can use to pick out your signs better.
