Abstract

The exclusive bus lanes in the Yeongdong Expressway were implemented in the Singal to Yeoju section in 2017, but the capacity of both exclusive bus lanes and general-purpose lanes of the Yeongdong Expressway decreased and the travel time increased, reducing it to the Singal to Deokpyeong section. Therefore, it is necessary to increase the efficiency of exclusive bus lanes to revitalize public transportation and improve environmental problems. This study calculated the willingness to pay and the social benefits of permission for Green cars to drive on exclusive bus lanes in Yeongdong Expressway. A survey was conducted on two groups of Green car users and Expressway users, and the willingness to pay was estimated using the CVM method. As a result, the average WTP of Green car users were estimated to be 218.7(won/km·person), and that of Expressway users were estimated to be approximately 235.5(won/km·person). The direct benefits were estimated to be approximately 7.9 billion won for Green car users, and 8.5 billion won for Expressway users in 2019. Finally, the value of time saving was estimated to be approximately 8.0 billion won.

영동고속도로 버스전용차로는 2017년 '신갈분기점~여주분기점' 구간에서 시행되었으나 전체 차로의 용량이 감소하고, 통행시간이 증가하여 '신갈분기점~덕평나들목' 구간으로 축소되었다. 대중교통 활성화 및 환경문제 개선 차원에서 버스전용차로 운영 효율을 높이기 위해 본 연구에서는 영동고속도로 버스전용차로 내 친환경차 주행 허가에 대한 가치를 평가하고자 이용자의 지불의사액 및 사회적 편익을 산정하였다. 친환경차 이용자와 고속도로 이용 경험이 있는 운전자 두 그룹을 대상으로 설문조사를 수행하였으며, 조건부 가치측정법을 이용하여 지불의사액을 추정하였다. 분석 결과, 친환경차 이용자의 평균 WTP는 218.7(원/km·인) 고속도로 이용 경험이 있는 운전자는 235.5(원/km·인)로 추정되었다. 또한, 2019년 기준 직접 편익은 친환경차 운전자가 약 79억 원, 고속도로 이용 경험이 있는 운전자가 약 85억 원으로 추정되었다. 마지막으로 통행시간 절감 편익에서는 약 80억 원의 편익이 있는 것으로 나타났다.
