NOTE 1 to entry: Intersections can be associated with zero junctions, such as a motorway crossing a road without any connecting ramps, or can be associated with one or more junctions, such as a diamond interchange.

space where two or more roads meet or cross
NOTE 1 to entry: Intersections can be associated with zero junctions, such as a motorway crossing a road without any connecting ramps, or can be associated with one or more junctions, such as a diamond interchange.
NOTE 2 to entry: Complex intersections can be viewed as multiple intersections by providing separate designations for distinct road links. For example, one model could depict a complex intersection as being associated with multiple junctions; another model could depict the same physical infrastructure as being multiple intersections that are interconnected by different roads, each with its own designator (e.g. “ramp from northbound Road A to eastbound Road B”).

ITS on-board equipment; on-board equipment (OBE)

vehicle system that provides all ITS functionality on-board the vehicle
NOTE 1 to entry: ITS on-board equipment relates to any functionality.

When there is a need to distinguish between core functionality and that by a special vehicle, the term can be further refined by indicating the type of vehicle to which the on-board equipment relates. For example, emergency vehicle on-board equipment can provide specialized functionality.
NOTE 2 to entry: The on-board equipment may also perform other functions.
