Abstract

The "Low Emission Zone" (LEZ) system restricts entry of vehicles with high air pollutants into city centers. Implementation of the system improves air environment around the world. Since 2012, operating restrictions have been applied to all of Seoul's metropolitan areas and some other metropolitan areas in the state. Beginning in December 2019, entry of 5th class vehicles to the central green transport zone of Seoul has been restricted. In this study we examine the status of operational restrictions in this zone, and predict the amount of traffic reduction expected when numbers of target vehicles are expanded in the future, we use data for each vehicle's emission grade: by region and 'Origin-Destination Traffic Volume'. After estimating the amount of traffic entering Seoul's 25 autonomous districts, by emission class, we propose a target region that may have a significant effect if target areas for automobile operation restrictions expand in the future.

전 세계적으로 대기환경 개선을 위해 대기오염물질 배출이 많은 차량의 진입을 제한하는 "공해차량 운행제한지역(LEZ : Low Emission Zone)" 제도 시행이 확산되고 있다. 국내에서도 2012년부터 서울시 전 지역과 일부 수도권 지역을 대상으로 노후경유차 운행제한을 시행하고 있으며, 특히 2019년 12월부터는 서울 도심인 한양도성 녹색교통지역에 진입하는 자동차 배출가스 5등급 차량의 운행을 제한하고 있다. 이에 본 연구에서는 녹색교통지역 자동차 운행제한 운영현황을 살펴보고, 기·종점통행량(O/D) 자료와 지역별 자동차 배출가스 등급별 자료를 활용하여 추후 운행제한 대상차량 확대시 등급별 교통량을 추정해 보고자 한다. 또한 서울시 25개 자치구에 진입하는 배출가스 등급별 교통량을 추정하여, 추후 자동차 운행제한 대상지역 추가 확대시 효과가 클 것으로 예상되는 대상지역(안)을 제안해 보고자 한다.
