For transportation network mathematical graph theory, see Flow network.

For broader coverage of this topic, see Proximity analysis.

A **transport network**, or **transportation network**, is a network or graph in geographic space, describing an infrastructure that permits and constrains movement or flow.^{[1]}
Examples include but are not limited to road networks, railways, air routes, pipelines, aqueducts, and power lines. The digital representation of these networks, and the methods for their analysis, is a core part of spatial analysis, geographic information systems, public utilities, and transport engineering. Network analysis is an application of the theories and algorithms of graph theory and is a form of proximity analysis.
