This document outlines the classifications of highways in both urban and rural areas. It describes the different functional classes including principal and minor arterials, collectors, and local roads. Principal arterials in urban and rural areas are designed for long distance travel and high speeds, while collectors and locals have shorter routes and focus on land access. Urban highways are further classified based on their role in carrying intra-city traffic and connecting to intercity routes. Freeways are fully limited access highways, while expressways have some access points but are also designed for high-speed travel.
