공해차량제한지역 제도의 실효성 증진을 위한개선방안 마련 및 효과분석

Abstract

The main goal of this study is to analyze problems and propose measures of improving the Low Emission Zone (below LEZ) System regarding its effectiveness. The first problem is that the crackdown of vehicles in violation is not working properly. This is due to budgetary constraints, and a low cost intervention method is needed to solve this problem. Considering the budget situation, the measure intensifying proposal is to introduce an LEZ sticker, which can be differentiated by colors along with the ages of vehicles. This measure makes it possible to expand vehicles affected by LEZ, when air pollution becomes worse. The second problem is about the fairness of the scope of LEZ with its vehicles. Currently, only the Seoul metropolitan area is under LEZ to improve the air quality, even though some of the other areas are worse than this area. This means that other areas also need LEZ. According to the situation, LEZ is required to include the downtowns of other areas, and the measures can reduce PM by 406 tons from enhancing LEZ by 2,958 tons yearly in case of extending LEZ. Lastly, LEZ vehicles restricted to old diesel are in need of expanding gasoline and LPG vehicles. LEZ is set to reduce PM10 from diesel vehicles which affect health badly. However, PM2.5 is more dangerous to humans than PM10 and is produced more in the air with NOx from gasoline and LPG vehicles than emitted directly from their vehicles. Moreover, their vehicles, such as the ones that run on diesel, emit more air pollutants as they get older. Considering this situation, gasoline and LPG vehicles should be under LEZ as well.
