Abstract

Detour behavior on the expressway means that the driver uses the local road by passing the part of the expressway which is stagnant at the time of the traffic demand such as holidays. Since the detour rate was estimated through the survey at toll gate in the past, there was a difficulty in estimating the actual detour rate due to the small sample of the survey. In this study, we use DSRC-based route travel data to conduct empirical studies on detour patterns such as the estimation of actual detour rate, the improvement of travel time using detour road, and the correlation between traffic conditions on the expressway and detour rate. On the day of Chuseok and the day before Chuseok, the analysis of Giheung-DongtanIC→OsanIC and Seopyeongtaek IC→Walgott JC showed that the use of detour roads increased gradually during the congestion of the main line and travel time reduced when using detour roads, However, when the traffic congestion of the main line is not severe, the travel time increases when using the detour roads. The correlation between the traffic condition of the expressway and the actual detour rate has a negative correlation, which is consistent with the congestion pattern of the main line. The results of this study can be used to overcome limitations of detour pattern research based on surveys in the past and to establish a detour strategy for expressway sections where traffic demand is concentrated.

고속도로 우회는 명절이나 연휴 등 교통수요가 집중되는 시점에 운전자들이 정체되는 고속도로 일부구간을 우회하여 국도 및 지방도를 이용하는 것을 의미한다. 기존에는 영업소 출구차량 우회 설문조사를 통해 우회행태를 분석하였으나 적은 설문조사 샘플로 인해 실 우회율 산정에는 어려움이 존재하였다. 이에 본 연구에서는 DSRC 기반 경로형 데이터를 활용해서 실 우회율 산정, 우회 시 통행시간 개선 효과, 그리고 고속도로 본선 소통상황과의 상관관계 등 '내-외내', '내-내' 우회행태에 대한 실증연구를 수행한다. 추석전날 및 당일 주요 우회도로인 기흥동탄IC→오산IC, 서평택IC→월곶JC에 대해 승용차, 버스 및 화물차를 포함한 3종 차량의 우회행태를 분석한 결과, 본선의 정체시간대에서 우회도로 이용률이 점차 증가하였다. 본선 정체가 극심한 경우에는 우회도로 이용 시 통행시간이 개선되었지만, 본선 정체가 극심하지 않는 시간대는 오히려 우회도로 이용 시 통행시간이 증가하였다. 또한 고속도로 본선 소통상황과 실 우회율의 상관관계는 음의 상관성을 가지며, 이는 본선의 정체 행태와 일치함을 확인할 수 있었다. 본 연구 결과는 기존의 설문조사에 기초했던 우회행태 연구의 한계를 극복할 수 있으며, 교통수요가 집중되는 고속도로 구간의 우회전략 수립 등에 활용되어질 수 있을 것으로 판단된다.
