6. Topology
The topological identification of arcs that
connect at a node. Within a linear network, the
from- and to-node numbers for each arc define
connectivity. So, arcs that share a common
node are connected.
Connectivity groups are used to model
multimodal transportation systems. For each
connectivity group, you select the network
sources that interconnect. In the subway and
street multimodal network example below,
metro lines and metro entrances are all
assigned to the same connectivity group.

8. CONNECTIVITY FUNCTIONS
Contiguity measures evaluate characteristics of
spatial units that are connected. These units share one
or more characteristics with adjacent units and form
a group. The term UNBROKEN is the key concept.
is a topological property relating to how
geographical features is attached to one another
functionally, spatially, or logically.
