Abstract

In planning and design process for all aspect of road network, traffic flow parameters estimation is crucial as such travel time which is the reciprocal of speed and is an indicator or a measure of the condition and maintenance of the road surface was established in the study using moving car observer method. A 1.2km stretch of the road which is Michael Opera Street of two lane spanning from Herbert Macaulay way to olusegun obasanjo way wuse zone 2 was used as test section. Before the rehabilitation of the road, a visual assessment of the road was carried and it was observed that cracks dominated in the pavement distress with about 62% followed by potholes and patches about 20%. The travel time was 3.06mins from A to B and from B to A it was 3.47mins having a flow of 713veh/hr and 700veh/hr with LOS B .However after rehabilitation the travel time reduced to 1.49mins and 1.56mins respectively and a flow of 1177veh/hr and 1014veh/hr was recorded respectively with LOS of C. This paper concludes that there was 51.3% and 55.04% reduction in travel time on both ways and the transportation policy of banning the mini buses from entering the wuse district made them move to this arterial to drop passengers a via berger junction and also the newly rehabilitated road attracted more traffic and we observed an increase in the motorization level after 8months of data collection, hence adverse condition, pavement distress reduces travel time.
