Crosspath

Crosspath is a term that appears in several disciplines to denote a connection, route, or intersection that links two paths or corridors. There is no single, universally accepted definition, and its meaning is typically determined by the context in which it is used. In some cases, crosspath describes a crossing or junction that enables movement between otherwise separate routes, while in others it refers to a connecting segment that ties together different networks.

In mathematics and graph theory, crosspath can be used to describe a path that intersects another path within a graph, or more broadly to denote a crossing between routes in a network. It may be employed in discussions of planarity, routing efficiency, and problems involving how paths intersect or overlap.

In urban planning and transportation, crosspath commonly refers to a connector or crossing designed to improve multimodal connectivity. Examples include pedestrian crosspaths, bicycle crossings, or mid-block connectors that link disparate streets or transit corridors to streamline movement and enhance accessibility.

In computing and networking, the term can appear in discussions of multipath routing or flow tracing, where data or requests traverse multiple intersecting paths to increase redundancy, reliability, or observability of a system. Crosspath concepts may also arise in visualizations of data flows or in route-tracing analyses across service architectures.

As a proper noun, Crosspath may designate specific projects, organizations, or software products. Because usage varies by domain, a precise definition should be inferred from the particular context in which the term is used. See also cross path, crossing, pathway, and multipath.
