Abstract

In this study, we calculated the driving duration of individual vehicles according to the availability of rest facility on highway, and suggested indicators indicating the potential risk of accidents caused by long-term driving with weights based on the number of vehicles by driving duration of individual links. Based on this, the methodology for estimating the appropriate location of the highway rest facility considering the driving duration of individual vehicles was presented. Using the DSRC individual vehicle data collected from the highways, the appropriate location of the rest facility was calculated by considering the driving duration by classifying weekdays and weekends for the Gyeongbu Expressway. The results showed that the weekly and weekend high risk indicators were different. In the case of weekdays, the risk indicators of Gimchun JC to Kumho JC for Busan were high, while for weekends, the risk indicators of Ansung JC to Dongtan JC for Seoul and Ansung IC to Bukchunan IC for Busan were high. This study has great significance in that it provides a framework for detailed analysis of link units by using non-aggregated data of individual vehicle units. In addition, it is significant that the reasonable driving duration reflecting the behavior of individual vehicles was calculated by analyzing the use of rest facilities.

본 연구에서는 휴게시설 이용여부에 따른 개별차량의 운전지속시간을 산정하였으며, 개별링크의 운전지속시간별 차량 수를 바탕으로 가중치를 적용한 장시간 운전에 따른 잠재적 사고위험도를 나타내는 지표를 제안하였다. 이를 바탕으로 개별차량의 운전지속시간을 고려한 고속도로 휴게시설의 적정위치를 산정하는 방법론을 제시하였다. 고속도로에서 수집된 DSRC 개별 차량자료를 활용하여 경부고속도로를 대상으로 주중과 주말을 구분하여 운전지속시간을 고려한 휴게시설 적정위치를 산정하였다. 분석결과 주중과 주말의 위험지표가 높은 구간이 상이한 것으로 나타났다. 주중의 경우 경부고속도로 부산방면 김천JC~금호JC 구간의 위험지표가 높게 나타났으며, 주말의 경우 서울방면 안성JC~동탄JC 구간과 부산방면 안성IC~북천안IC 구간의 위험지표가 높게 나타났다. 본 연구는 개별차량단위의 비집계자료를 활용하여 링크단위의 상세한 분석을 수행할 수 있는 틀을 제공하였다는 점에서 큰 의의를 가진다. 또한 휴게시설 이용여부 분석을 통하여 개별차량의 행태를 반영한 합리적인 운전지속시간을 산정하였다는 점에서 의의가 있다.
