surface is a property of something man-made, i.e. it's in the human  
geography domain. It makes perfect sense for roads and traffic  
infrastructure. As a matter of lingual preference, I also prefer  
"surface" to describe something 2-dimensional, i.e. I do not like e.g.  
surface=building. Generally, surface is the property of something else.
