Memphis MPO Functional Classification System Guidelines

interstate highway

Functional classification is the process by which streets and highways are grouped into classes, or systems, according to the role it plays in the overall system of the local, state and nation’s street and highway network. It determines how travel is “directed” within the roadway system by defining the part that each road or street plays in serving the flow of traffic through a highway network. It is a hierarchal system of classification that helps to ensure a comprehensive roadway system that provides logical connectivity and continuity across the entire network.
