Abstract

Abstract: We analyzed the spatiotemporal characteristics of air pollutants, meteorology, and average road speed during a heavy haze pollution period; and explored the combined impacts of temporary traffic restrictions and meteorological conditions on air quality. The results showed that five pollution stages were identified with remarkable variation patterns based on the evolution of PM_2.5 concentration and weather conditions; and it also showed that the southern sites experienced heavier pollution than the northern sites. Stage P3 exhibited a combined effect of meteorology and traffic restrictions with delayed functions. A good AQI was more likely with higher temperature and lower humidity. Traffic restrictions played visible effects on traffic-related pollutants, like CO and NO₂, and delayed peak-clipping effect on PM_2.5.
