Evaluation of Connectivity Algorithms in Road Network Analysis of Oriire Local Government Area of Oyo State, Nigeria

Rural road network has been considered as the combinations of several routes into a more or less integrated structure permitting movements between many nodes. The study evaluated road network level of seven (7) villages in Oriire LGA of Oyo State. Oriire LGA is one of the agricultural producing areas of Oyo State this is because the major occupation is agriculture. Geographical information system was used to capture the road network pattern of the study area. Connectivity indices such as alpha (α), beta (β), gamma (γ) and cyclomatic number (μ) were adopted to evaluate the level of connectivity. The result revealed that, (α = 0.87), (β = 1.87), (γ = 0.78) and (μ = 7) which are significant as 0.5, 0.1, 0.5 and 1-10 respectively. These values indicated that, the selected villages have nodal connectivity of at least three (3) and that, the connectivity level is at medium. The study concluded that, the study area is connected by roads however, the connectivity do not tend to the most important village (Tewure) the rural commercial center. It is therefore suggested that, Onigba with the highest nodal connectivity be made a mini-rural market.
