Part 1 - A Matter of Consistency!


If there is ever a doubt about people understanding traffic signals, wouldn't it help us in educating the public about them if there was some consistency in their application?

It is not the intention here to pick on any one city, county, region, or other group in particular. I think just about everyone has made some mistakes with regard to consistency within their jurisdiction. Also, there are many times we are stuck with legacy installations that there is no budget to remedy. Furthermore, standards vary from jurisdiction to jurisdiction.
