초록

The use of bus stop in the center lane has reduced the emissions of exhaust gas on the road due to theimprovement of the traffic speed but has caused a health problem for the citizens who are waiting for the bus in theplatform, and thus the air pollution control of bus stop in the center lane is emerging as a more important part. Thisstudy was conducted to investigate the air pollution degree for the center lane-bus stops in four regions usingmobile air measuring vehicle, and to evaluate the characteristics of air pollution by comparing with the datameasured at the urban air monitoring site close to the bus stops. In addition, the correlation analysis was performedto analyze the impact to neighboring region by vehicle exhaust gas. The regional mean concentration of nitrogendioxide in the center lane-bus stops ranged from 0.025 to 0.043 ppm which shows from 2.5 times to 5.3 timeshigher than the values of urban air monitoring site selected as a control group. The regional mean concentration ofozone in the center lane-bus stops ranged from 0.023 to 0.034 ppm which shows from 3% to 28% lower than thevalues of urban air monitoring site selected as a control group. The concentrations of nitrogen dioxide and ozonefor the sampling regions did not exceed one hour-air quality environmental standard (0.1 ppm).
The mean concentration of particulate matter for four center lane-bus stops was 28 μg/m3 which shows about27% higher than the values of urban air monitoring site selected as a control group, and that of particulate matterdid not exceed one day-air quality environmental standard (100 μg/m3). In the results of correlation analysisbetween data from center lane-bus stops and data from urban air monitoring sites, the correlation coefficient (r) ofnitrogen dioxide was relatively low as 0.316 to 0.416, and the correlation coefficient was high as the distance wasclose and vice versa. However, the correlation coefficient of ozone ranged from 0.167 to 0.658 and the correlationcoefficient was high as the distance was far and vice versa.
