THE STUDY OF THE FLOW OF TRAFFIC DUE TO HEAVY DUTY TRUCKS MOVEMENT ALONG THE ILARO-IBESE ROAD IN OGUN STATE
The number and quantity of vehicles on roads has increased due to technological and economic development in recent years. As a result of this increase, traffic has been one of the most important parts of our daily lives as people spend more time in traffic thereby forcing drivers and other road users to face a higher risk of traffic accident. Traffic congestion occurs as a result of interaction between vehicles on the road. The effect of that interaction is expressed in fundamental law of traffic, the speed flow curve (TRB, 2011). This was described by Goodwin, (1997), in his inaugural lecture at University College, London in 1997 as follows : the fundamental defining relationship of our field, the spend-flow curve shows that the more traffic uses a road, the slower it goes, the effect becoming more and more severe as the traffic flow approaches the maximum capacity of the network, until finally over load is so extreme that all vehicles are unable to move.
