physical hardware engineering object that is a run-time computational resource and generally has at least memory and processing capability

NOTE 1 to entry Run-time software engineering objects reside on nodes; node has some well-understood, possibly rapidly moving, location [a node may be composed of two or more (sub) nodes].

zero-dimensional element that is a topological junction of two or more edges, or an end point of an edge

NOTE A node is created for topologically significant points, such as simple intersections of roads or other linear features including boundaries but also for locations such as electric beacons, kilometre-posts or sensors detecting traffic flows, being significant points specified in a map.

<road network> component of a road model representing a point location of the road network graph

NOTE 1 to entry The point location typically represents a point along the road which can be used to designate the location of a junction, public transport stop, jurisdictional boundary, termination point, etc.
