The entities included in the dataset represent the Belgian road transport network in the sense of the Inspire European directive. The dataset comprises several classes.

The RoadLink class represents, in a linear manner, all of the road links between each pair of dots for the network considered. The footpaths, cycle paths or carriageways that connect the pairs of dots correspond to as many entities in the class.

The RoadServiceArea class represents the sections of space devoted to auxiliary road transport functions, such as service stations or rest areas.

In addition to this are two classes without geometry. RoadWidth class describes in metres the width of each segment of the "road links" class. The "functional importance" class ranks the segments of the "road links" class by functional importance on the road transport network.
