The extent to which a nation’s landmass is covered by
road network is an index of the degree of mobility of
people, goods and services within the country, and the
quality of the network measures the ease and cost of
that mobility. Roads dominates the transport sector in
most developing countries carrying eighty to ninety
percent of passenger and freight. It plays a critical role
in the entire transportation chain in that it connects other
modes of transportation and permeates all aspects of
modern economic activities in the economy. Hence the
objectives of this study which examines spatial structure
of road infrastructure in Ekiti State Nigeria; options for
transformation are to determine the level of connectivity
of road networks in the study area and also to determine
the most accessible node from other significant nodes
in the study area. To get a topological characteristics of
the transportation network in the study area, a graph of
the road network of Ekiti State was abstracted from the
map sourced from the federal Road Maintenance Agency
FERMA (Ado Ekiti Office). The most commonly used
graph theoretic measurement of Karsky (1963) namely;
the Beta (ß) index, the Gamma (?) index and the Alpha
(a) index were used to determine the connectivity of
road networks in the State. Shimbel index and associated
number methods were also used to determine the most
accessible node from other notable nodes in the study
area. The results showed that the connectivity level is low
with Beta index 1.39, Gamma index 0.49 and Alpha index
0.24. Result from the accessibility analyses showed that
Ado-Ekiti is the most accessible node from other notable
nodes on the study area. The study recommends options
for the transformation of the road transport sub-sector in
the study area.
