Diagram illustrating the calculation of the a degree, b connectivity, and c access degree indicators on the same network sample. In this example: a degree is the number of ways that intersect the reference way wref, i.e., 4; in b, connectivity is the number of arcs intersecting wref, i.e., 5; and in c access degree is the number of ways crossing wref in an X-intersection, i.e., 1
