You might be better served with a database type search with this task, like character detection or eigenfaces. Create a database of traffic signs, then check if the above image has any of the signs you have in your database. Otherwise, the moment you change the lighting, your generalized identification method will likely break.

I would experiment with the colorThresholder app, in the HSV space. You could either threshold on red hues (the edges of the sign), or blue hue (the inside of the sign).
A quick play with the app gave me the following code:
roadimg = imread('1.jpg');
hsvimg = rgb2hsv(roadimg);
binaryimg = hsvimg(:, :, 1) >= .579 & hsvimg(:, :, 1) <= .705 & ... %filter on hue
hsvimg(:, :, 3) >= .310 & hsvimg(:, :, 3) <= .629; %filter on value

I don't think this is really a MATLAB question. There are lots of algorithms for finding road signs. You can find most of them listed here: http://www.visionbib.com/bibliography/active693.html#Road%20Signs,%20Traffic%20Signs,%20Objects%20along%20the%20Road,%20Inspections
Pick one, and code it up.

Sorry, I don't have the code for that paper. http://matlab.wikia.com/wiki/FAQ#Can_you_program_up_the_algorithm_in_this_article_for_me_and_explain_it_to_me.3F And writing it for you would take much more of my time that I'm willing to donate to you. I hope you understand. I suggest you ask the authors for code - they already have it, I don't.

Can someone send me the code for traffic signboard detection and recognition from a video?
