Particulate matter negatively affects personal health and daily living; hence, it has become a popular topic in academia. Transportation-related variables have thus far not been extensively explored, even though various factors associated with particulate matter have been investigated. In particular, the amount of particulate matter emitted from vehicles depends on the speed of travel, which can be adversely affected by traffic congestion. Hence, we aim to examine the causal relationships between concentrations of particulate as well as ultrafine particulate matter and traffic congestion. To investigate the effects of traffic congestion on concentration of particulate matter, we used big data regarding various urban parameters, such as travel speed, air pollution, and climatological data, by employing fixed-effects panel data analysis models. We use the real-time congestion index (RCI) to calculate traffic congestion, in addition to precipitation, wind speed, wind direction, and temperature as the control variables. The main findings from the panel models are as follows: First, traffic congestion is directly related to the concentrations of particulate and ultrafine particulate matter. In particular, an increase in one unit of RCI increases the concentration of the particulate matter by 3.3 ㎍/㎥ and ultrafine particulate matter by 1.7 ㎍/㎥, after accounting for other factors. Second, the impact of traffic congestion is greater when the concentration of particulate matter is less than 30 ㎍/㎜ (also called the “good condition“ of PM<SUB>10</SUB>) and that of ultrafine particulate matter is above 35 ㎍/㎜. (called the “bad condition” of PM<SUB>2.5</SUB>). Third, the effects of traffic congestion on particulate matter are greater during non-rush hours than during rush hours. This is probably because of the greater number of vehicles on the roads during non-rush hours, such as older/obsolete vehicles, trucks, and diesel-powered vehicles, which are likely to emit more pollutants. Our results suggest that alleviating traffic congestion in addition to existing air pollution policies could improve air quality, even though such effects may not be substantial.
