Box 11- 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.
