intersection
crossing and/or connection of two or more roads
NOTE In GDF, an intersection is a Level 2 representation of a junction which bounds a road or a ferry. It is a complex feature, composed of one or more Level 1 junctions, road elements and enclosed traffic areas. The definition is different from GDF because the location referencing system refers to real-world objects rather than a database definition as defined in GDF.
