According to the reviewed literature, road users are constantly exposed to tricycle emissions and other environmental pollutants, which may be hazardous to health and cause climate change due to air pollution consequences, as described by a few academics. CO, N2O, SO2, CH4, H2S, PM, S2O, Pb, and VOCs were found to be above NAAQS and FMEnv, indicating that the ambient air around Nigerian towns and cities was polluted. The accumulation of pollutants in the air, on people (road users), and in the immediate environment creates major health and environmental dangers. If not carefully monitored, the occurrence of these contaminants in humans and the environment may tend to increase in the coming years, having a harmful influence on man and the ecosystem as a whole. As severe as it gets human and climatic changes have unavoidable health consequences. As a result, regular re-evaluation of tricycle emissions and their influence on human health and the environment is essential.

INTRODUCTION Rising income levels in many emerging nations have resulted in some changes in household living patterns [1], and these lifestyle changes have an impact on energy demand in various sectors of the economy [2]. One such area is transportation. Transportation is an
