| description | The primary aim of the research is to quantify and analyze the traffic noise emissions along Oba-Adesida –Oyemekun
Road. Measurements of noise were recorded in decibel (dBA) using digital sound level meters (IEC651 Type 2). While,
the traffic volume and spot speed were obtained using cine –camera at six selected locations namely Alagbaka(L1),
Biological Garden(L2), Adegbola(L3), Ondo Bye Pass(L4), Ilesha Garage(L5) and FUTA junction(L6) along ObaAdesida-
Oyemekun road during the peak period(7:30am -8:30 am & 4:00pm-5:00pm) and off peak period(11:30pm-
12:30pm), repeated 3-5 times to account for time-fluctuation of these variables. All measurements were taken on a
weighting frequency network, at a height of about 1.5m from the ground level. The vehicles were divided into five
categories namely Cars, buses, motorcycles,2-axle load, and 3-axle loads; and were converted into “Passenger Car Units”
(PCU) by multiplying with recommended factors in accordance with Nigerian Federal Highway Capacity Manual
2006.The average L10(dBA) are 72.8, 73.8, 73.4, 74.4, 73.9, and 75.0dBA ; while average combine sound pressure
level(SPL) in dBA are 76, 77, 78, 78, 77, and 78dBA for L1, L2, L3, L4, L5,and L6 respectively. Findings indicated that
traffic generated noise pollution is at or above, the standard outdoor limits in most locations and area can adversely affect
the welfare activities.
The present study revealed that the study area is getting noisier due to high traffic density and lack of traffic
management, practical action to limit and control the exposure to environmental noise are essential. However, road traffic
noise by treatments at source (such as to reduce engine noise, exhaust pipe noise etc.) is to be encouraged as the principal
method of control. The techniques include road design, the management of traffic flow and the use of screens and barriers. |
