Abstract

In Jeju-Do, there is the 1100 Road, 516 Road, and Bijarimro, which are typical mountain sight-seeing roads in Jeju. These roads are local roads that have been the location for many traffic accidents. This study focused on these roads, categorized the type of traffic accident and analyzed the accident characteristics. The major accident factors were analyzed through trip AHP analysis, Comparative analysis of the velocity distribution and the factors affecting traffic accidents were analyzed. Tourists took many trips on these roads. The mixing rate of the rental cars was 36.70%~71.60% in 1100 road and Bijarimro. Currently, these local roads are regulated by a speed limit of 60km/h. However, it might be necessary to reduce the speed limit to 40km/h considering the geometric line form of the road and the climate in these areas. The speed limit of more than 40km/h is found 87.0% on 516 Roads, 88.57% on 1100 roads, and 93.1% on Bjarimro, In these roads, the speed ratio is higher as described above. Therefore, these roads have been found to have a higher risk of traffic accidents by overspeeding driving. The overspeed driving ratio of these roads was 87.0%~93.1%, The overspeed driving enforcement method at one spot has only the effect of reducing the speed at that enforcement place; the effect cannot be expected for the other places or sections. It is necessary to introduce a section overspeed driving enforcement system utilizing the average velocity in these areas to prevent traffic accidents.

본 제주도 산악관광도로를 대표하는 교통사고가 잦은 지방도 1100도로, 516도로, 비자림로를 중심으로 교통사고를 유형별로 구분하여 사고특성을 분석하고, 통행 AHP 분석을 통해 주요 사고요인을 분석하고 지점속도의 분포와 교통사고에 영향을 미치는 요인들을 비교 분석하였다. 도로특성상 관광객이 통행이 많고, 렌트카의 혼합율이 1100도로 및 비자림로는 36.70%~71.60%로 분석되었으며, 현재 조사대상 지방도는 60km/h의 제한속도로 규제하고 있으나, 도로선형 및 기후, 경관 등의 운전자 시거를 고려할 경우 제한속도를 40km/h로 규제할 필요성이 있으며, 조사대상 지방도의 40km/h이상 과속비율이 516도로는 87.0%, 1100도로는 88.57%, 비자림로는 93.1%로 분석되어 과속의 비율이 높은 것으로 분석되었으며, 과속에 따른 사고위험에 노출되어 있는 것으로 분석되었다. 516도로, 1100도로, 비자림로의 과속비율이 87.0%~93.1%로 무인과속단속시스템은 한 지점의 속도만으로 과속을 단속하는 시스템으로 단속지점에서만 속도를 줄이는 캥거루효과가 발생하고 있어 연속적인 속도감소 효과를 기대할 수 없다. 따라서 제주도의 도로특성상 연속적인 위험이 존재하는 도로구간에서는 교통사고 예방을 위해서는 위험구간의 평균속도로 과속차량을 단속하는 무인구간속도 위반단속시스템 도입이 필요하다.
