  In this paper, we study the structural properties of the complex bus network
of Chennai. We formulate this extensive network structure by identifying each
bus stop as a node, and a bus which stops at any two adjacent bus stops as an
edge connecting the nodes. Rigorous statistical analysis of this data shows
that the Chennai bus network displays small-world properties and a scale-free
degree distribution with the power-law exponent, $\gamma > 3$.
