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.
