Abstract
This paper examines the effects of ambient air pollution by ozone and particulate matter on traveling by mode of transport. We estimate the SUR model of travel time by different modes of transportation using individual level data of travel diaries. We find that, as air pollution levels rises, traveling by privately-owned vehicles increases but traveling by bus decreases. Our results also show that, when an air quality alert is issued, bus traveling increases in an effort to reduce pollution levels, but traveling by own car does not change and traveling by train declines. This suggests that alert programs may not be highly effective in reducing air pollution emissions from vehicles because voluntary switching to public transportation induced by air quality alerts is outweighed by individual effort of avoiding exposure to pollution.

본 논문은 오존과 미세먼지 수준이 도보, 자가용, 버스, 전철의 통행시간에 미치는 영향을 분석한다. 가구통행실태조사 자료와 SUR 모형을 이용하여 분석한 결과, 대기오염 농도가 높아질수록 자가용 통행시간이 증가하고, 버스의 통행시간이 감소하는 것으로 나타난다. 그러나 대기오염 경보가 발령되면 버스의 통행시간이 증가하는 공익적 행위가 일부 나타나지만, 자가용의 통행시간이 증가하거나 변화가 없고, 전철의 통행시간이 증가하지 않는 것으로 나타난다. 이는 경보의 발령으로 제공되는 정보가 배출 저감을 위한 통행행태 변화보다는 오염상황에의 노출을 줄이는 회피행동에 더 큰 영향을 미쳤음을 시사한다.
