Connectivity

Connectivity expresses the adjacency for linear networks. It links the constitutive segments of the network. When a distribution network of fluids (gas, water, electricity) or people is modeled, the connectivity is called to be oriented. In contrast, road networks are traversed in both directions, with exception of one-way streets. Connectivity is described by means of graphs and matrix, to indicate which elements are connected to each other. (Theriault 1994)
