Abstract

As part of measures to address the climate crisis, buses are also being converted to electric and hydrogen buses. Local authorities need to prioritize carbon emissions when allocating newly introduced and converted electric and hydrogen buses, and as a method, consider the introduction of Low Emission Bus Zones (LEBZ) to propose the reduction of pollution from specific links. To introduce LEBZ, it is necessary to compare the carbon emissions before and after its implementation, yet there is a shortage of studies that focus solely on buses or analyze the effects of introducing LEBZ to specific links. In this paper, we utilized bus information system data to calculate and compare the effects of introducing LEBZ to bus priority lanes in Jeju. We categorized scenarios into five groups, with scenarios 1 through 4 involving the introduction of LEBZ, and scenario 5 designating cases where LEBZ was not introduced. Comparative results confirmed that in scenarios with LEBZ introduction, the reduction per km reached a maximum of 0.097t per km, whereas in cases without LEBZ, it amounted to 0.022t per km, demonstrating higher efficiency. It underscores the significance of conducting carbon emission calculations and comparing the effects of LEBZ introduction using bus information system data, which can be directly applied by local authorities to make informed and rational decisions.

기후위기 대응을 위한 대책으로 버스도 전기, 수소 버스로 우선 전환되고 있다. 지자체는 신규 투입, 전환되는 전기, 수소 버스 배정의 우선순위를 탄소배출량에 따라 판단할 필요가 있으며 그 방법으로 특정 구간에 무공해버스 운행만 허용하는 LEBZ 도입을 고려할 수 있다. LEBZ를 도입하기 위해서는 도입 전후 탄소배출량 절감 효과를 비교할 필요가 있으나 LEBZ도입 방안과 도입 시 효과를 분석하는 연구는 부족한 상황이다. 본 논문에서는 버스정보시스템 데이터를 활용하여 제주특별자치도를 대상으로 버스우선차로에 LEBZ 도입 시 효과를 산출하고 비교하였다. 분석 시나리오를 총 5개로 구분하여 시나리오1부터 4까지는 LEBZ 도입, 시나리오5는 LEBZ를 지정하지 않고 일부 차량만 전기, 수소 버스로 전환하는 경우로 구성하였고, 버스정보시스템 자료를 이용하여 탄소배출량을 비교한 결과 LEBZ를 도입한 경우가 km당 감축량이 최대 0.097t, 그렇지 않은 경우가 0.022t으로 LEBZ 도입은 높은 효율을 보임을 확인하였다. 본 논문은 제안한 버스정보시스템 데이터를 활용한 탄소배출량 산출 및 LEBZ 도입에 따른 효과 비교를 통해 각 지자체에서도 전기, 수소 버스 투입 시 의사 결정을 보다 합리적으로 할수 있는 방법론 제시에 의의를 두었다.
