In an effort to adapt cities to automobiles and trucks, traffic engineers introduced the notion of the functional analysis of streets.
Duplicated in many street design manuals, it takes the form of a graph analysing streets as having two functions: mobility or the movement of traffic through an area, and access to land uses along them. The more a street is dedicated to through traffic, the less it should allow access to adjacent land uses.
