Introduction
It is known that air pollution had adverse effects on the health of those exposed to it. There is a diverse mix of air pollutants and the most common pollutants in outdoor air include carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), ground level ozone and particulate matter (PM) (1). Outdoor air pollution is a mixture of gases and particulate matter (PM) of varying sizes and it is often difficult to isolate the source of the PM from all the possible sources of combustion (1). Traffic-related air pollution (TRAP) is a significant contributor to air pollution in urban areas and motor vehicles release a mix of combustion and non-combustion emissions, with fuel combustion producing carbon dioxide (CO2), CO, NOx, PM, and volatile organic compounds (VOCs) (1). PMs are particularly more dangerous due to their effect on the respiratory system and their ability to worsen overall health in those with already compromised health. PMs varying in size from between 2.5 μm and 10 μm in diameter are usually deposited in human nasopharynx, while finer PM of 2.5 μm and smaller in diameter are deposited in the bronchioles and in the alveoli of the human lungs (1). The fact that there is a positive correlation between poor air quality as a result of air pollution and ill health is well recognized and documented. Therefore any attempt to implement policy to reduce traffic is bound to yield a degree of improved air quality.
