BOX 2-A
Highway
Functional Classification System
The
Federal Highway Administration classifies roads according to the type of
service provided and the type of area (urban or rural). There are three main
types of roads: 1) arterials that provide the highest level of mobility for
longer, uninterrupted trips; 2) collectors that collect and distribute traffic
from the arterial network and connect with local roads; and 3) local roads that
provide direct access to residences and businesses.
