DATEX II packages addressed by the RRP The types of data on infrastructure
Road network links and their physical attributes
Junctions
The reference profile defines the minimum required information to identify the location of a junction and its relationship to other elements of the road network.
While network nodes are often used for technical modeling purposes—such as introducing a new road link to reflect changes in physical characteristics (e.g. a change in road width or number of lanes)—junctions serve a distinct purpose. They represent decision or choice points where traffic may be directed onto alternative routes.
A junction’s relationship to the rest of the network can be expressed by indicating whether it functions as the start or end point of a given road link.
