{{Short description|Connected system of roads}} A '''street network''' is a system of interconnecting lines and points (called ''edges'' and ''nodes'' in network science) that represent a system of streets or roads for a given area. A street network provides the foundation for network analysis; for example, finding the best route or creating service areas.<ref>Wade, T. and Sommer, S. eds.

They greatly affect in-town movement and traffic. Street networks can become very complex in cities. Street networks are very often localized, because there is little non-highway transportation from town to town. The U.S. Highway System is like a street network, but it is national, and consists of highways instead of streets and roads.
