Road transportation is identified as the largest contributor to urban air pollution which accounts for about 3.7 million pre matured death from 2012 to 2024. This study aims at assessing the air quality around the major traffic hotspots in Ikot Ekpene Urban. Empirical research design was employed for the study, and the hotspots were geospatially identified. The air quality was measured using highly sensitive digital portable meters. From the result, mean value of Nitrogen Dioxide is at 0.1, Sulphur Dioxide (SO2) at 0.1, Hydrogen Sulphide (H2S) at 0.12, Carbon Monoxide (CO) at 2.9, Ammonia (NH3) at 2.6, Chlorine Gas (Cl2) at 0.16, Hydrogen Cyanide (HCN) at 1, Total Volatile Organic Compounds (TVOC) at 2.2, Formaldehyde (CH2O) at 14.7, and Particulate Matter (PM2.5, PM2.10) at 66.63 and 110.966 respectively. This reveals that the available Nitrogen Dioxide (0.1) in the atmosphere exceeded the limits set by Federal Ministry of Environment which is 0.6, while other parameters are within their limits. These findings provide baseline for proactive approach to public transportation planning. The urgency for transport plan, traffic management scheme, and the necessity of a shelterbelt to curtail the accumulation of air pollutants around the traffic hotspot.Keywords: air quality, traffic hotspots, road transportation, environmentalsustainability.
