Abstract

Purpose: Traffic isolation on highways caused by heavy snowfall results in significant damages and losses. To prevent this, traffic volume must be controlled in advance. This study aims to establish criteria for traffic volume control. Method: This study analyzed the critical thresholds for traffic isolation by examining data recorded over the past 10 years during heavy snowfall events in the Yeongdong region where cumulative snowfall exceeded 30cm under heavy snow warnings. The data included zone-specific snowfall intensity, traffic volume, and travel speed recorded by the VDS(Vehicle Detection System) on highways. Result: The analysis revealed that traffic congestion occurred when hourly snowfall exceeded 10cm or traffic volume exceeded 1,500 vehicles per hour. Furthermore, traffic isolation was observed when hourly traffic volume reached approximately 2,200 vehicles. Conclusion: When a heavy snow warning is issued, continuous monitoring of traffic volume through the VDS system is essential. If traffic volume exceeds 1,500 vehicles per hour and an increase is anticipated, proactive traffic volume control measures can effectively prevent traffic isolation.

연구목적: 폭설 시 고속도로에서 발생하는 교통의 고립은 많은 피해 및 손실을 야기한다. 이에 대한 대응전략으로 국내·외에서는 신호제어, 램프미터링 기법을 활용하여 교통량을 통제하는 전략을 검토하고 있다. 이 전략을 시행하기 위해서는 교통량 통제의 기준이 먼저 정립되어야 한다. 따라서 본 연구는 폭설에 취약한 국내 영동지역 고속도로 노선에 대하여 교통량 통제의 기준을 도출하고자 한다. 연구방법: 최근 10년간 강설량, 교통량, 통행속도 데이터를 분석하여 폭설 시 교통 정체 및 고립이 발생하는 강설 및 교통량의 임계점을 도출하였다. 연구결과: 연구결과 폭설 시 시간당 강설량이 10cm 이상이 되거나 교통량이 1,500대 이상 일 때 교통 정체가 발생하였으며 교통량이 2,200대 이상 시 교통 고립이 발생하였다. 결론: 대설경보가 발효되면 VDS를 통해 교통량을 지속적으로 모니터링하여 교통량이 1,500대가 이상 일 시 교통량의 증가가 예상된다면 선제적으로 교통량을 통제한다면 교통의 고립을 예방할 수 있다고 판단된다.
