Road Links and Road Nodes forming the base network geometry of the OS MasterMap Highways Network – Roads
A Road Link is a line segment representing the general alignment of the road carriageway. It can represent single carriageways, dual carriageways, slip roads, roundabouts and indicative trajectories across traffic squares. It defines the geometry and connectivity of a road network between two points. Road Links hold information on the road name, classification, form, length and other attributes which are specified in the [OS MasterMap Highways Network – Roads Technical Specification](/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-roads/os-mastermap-highways-network-roads-technical-specification.md).
