ABSTRACT: This paper assesses the topological properties of Akure road network using graph theory. Three 1,609-square meters of different urban street sections were sampled from Akure road network map and developed into graphs using the primal approach. The resulting graphs were then described by their adjacency matrices. Investigation into the topological properties of the resulting graphs revealed that the three networks produced possessed small average clustering coefficients of 0.007, 0.016, and 0.026 and small average path lengths of 0.066, 0.088 and 0.062. The paths lengths obtained deviated from one obtained when it was assumed to be randomized. The degree distribution obtained over the networks could not be approximated using either binomial or Poisson distribution. Further investigation revealed Akure road network exhibited a power law degree distribution.
Keywords: Network, graph theory, topology, clustering coefficient, path length, degree distribution, scale free network.
