초록
Field experiments were carried out to analyze the relation between the particulatematter and the vehicle traffic in the surrounding roads near a Institute of Health and Environment(IHE) located at Yuseong-gu, Daejeon. Also, major facts to generate the particulate matter wereanalyzed using the past measured data. As a result of the analysis, the contribution of the particulatematter from the vehicles in a road showed to take a large portion in 2015 and 2016. As a result ofconnection with traffic data in Daejeon, the concentrations of particulate matter increased duringrush hour and they showed the similar patterns near a IHE. The generation rates of the particulatematter from the vehicles presented a large portion in summer and winter that inflow from thesurrounding cities have been relatively small, and it always occurred for the conditionswithoutrainfall. It is anticipated that the concentration of PM10 generated by the road traffic would bereduced in the range of 10 μg·m-3~14 μg·m-3 through the control and detour of vehicles.
