Lecture 26
Connectivity of Transport Network
Any network has three elements
The nodes
The routes or edges
Independent or unconnected part of the network
A useful first step in the analysis of network is to construct a connectivity
matrix. This shows which nodes have direct links with each other and which
do not have direct links. If each node are connected directly to every other
node then all cell in table would contain the symbol 1. Thus the more
frequently the symbol 1 appears in the matrix, the network is more
interconnected.
The final measure of network characteristics to be discussed here is the
β
index. This provides an alternative way of describing the complexity of the
network.
β
index
=
e/v
e
=
number of edges/routs
v
=
number of nodes or vertex/vertices
An index 1 describes a network with just one circuit and the figure increases,
as the structure of the network grows more complex, with an increasing
number of edges in relation to vertices or nodes.
