Abstract

This study aims to propose a method for the estimation of operational delay cost using transportation card data in bus accidents. Average operational delay time from bus accidents was surveyed among 12 bus companies through an interview method. Then, the operational delay cost was estimated using actual traffic accident data and transportation card data. Results showed that average loss time per bus accident was found to be 45 minutes. In addition, total occupancy of 659 was estimated for the accidents investigated using transportation card data, resulting a total loss time of 494.25 hours. An estimated operational delay cost was 186.9 thousand won per accident, which was 6.37% of social agency cost. The magnitude of this number implied that operational delay cost may have a significant impact on traffic accident cost if included.

본 연구에서는 버스사고 발생 시 교통카드자료를 이용한 운행지연비용을 추정하는 방법을 제안하였다. 12개 버스회사를 대상으로 설문조사를 통하여 사고 시 평균 운행지연시간을 조사하였고, 실제 교통사고자료와 교통카드자료를 기반으로 운행지연비용을 추정하였다. 조사결과 버스사고시 운행지연으로 평균 45분의 손실시간이 발생하는 것으로 파악되었다. 교통카드자료 분석결과 사고가 발생한 노선의 재차인원의 총 합은 659명으로 추정되었고, 이에 따른 손실 시간은 총 494.25시간으로 계산되었다. 본 방법론으로 추정된 운행지연 비용은 약 186.9천원/건이며, 이는 사회적기관비용의 6.37%에 해당하는 값으로 나타나 운행지연비용이 도로교통사고 비용에 유의한 영항을 미치는 것으로 평가되었다.
