ABSTRACT
The research work examined the road network connectivity and traffic congestion in the CBD. Three objectives were formulated, firstly to examine the road network connectivity in the CBD of Benin City; secondly to examine the level of accessibility in the CBD; thirdly to make recommendations for traffic congestion problems. The graph theoretic technique was employed and the rate of road network connectivity was computed. The findings show that the road network in the CBD is well connected with 100% Alpha (α) value as over 50% of the roads in the CBD are tarred, while 0% Beta (β) value shows that the road network in the CBD is not complex, while the 0% Gamma (γ) value indicates a poor road network. Chi-square was also used to examine the level of accessibility and connectivity in the CBD and the test statistics showed a significant X2-value of 43.635 and 66.124. This indicates that the road network in the CBD is moderately connected and accessible. The implication of this is that, although the road network in the CBD of Benin City is moderately connected but it still experiences traffic congestion. This is largely because of the lack of parking space/garage for public transport and private car owners thereby reducing the traffic corridor. Also, congestion in the CBD of Benin City occurs as a result of on-street trading, presence of bad roads and lack of discipline on the part of drivers. The study is of the opinion that the government should fund traffic volumetric studies to enable them plan for traffic management and also to enable them know the trunk roads that need expansion and maintenance and also it will enable them to provide for parking demands and proper parking facilities.
