Page 314 Roadway and area classification Most highways and street systems encompass several classes or types of roadway and walkways. At one extreme are high-speed, high-volume facilities carrying through traffic, with no attempt made to serve abutting property, pedestrians, or local trips. At the other extreme are local highways, streets, or roads that carry low volumes, at low speeds, with a primary function of land access rather than vehicular movement. A comprehensive lighting program requires that the roads and streets be classified on the basis of intended function. The following classifications are those recommended by the Illuminating Engineering Society

Classification definitions
 * 1) Freeway: This is a divided major roadway with full control of access and with no crossings at grade. This definition applies to toll as well as nontoll roads.
 * 2) Freeway A: This designated roadways with greater visual complexity and high traffic volumes. Usually this type of freeway will be found in metropolitan areas in or near the central core and will operate through much of the early evening hours of darkness at or near design capacity.
 * 3) Freeway B: This designates all other divided roadways with full control of access where lighting is needed.
 * 4) Expressway: A divided major roadway for through traffic with partial control of access and generally with interchanges at major crossroads
