숲길 이용난이도 산출 연구 = A Study on Assessment of Difficulty Level of Forest Trail

다국어 초록 (Multilingual Abstract)

This study was conducted to present assessment criteria and application standards that classify difficulty levels of forest trail. Assessment criteria and application standards were derived from reviews of Korean and foreign references, and AHP analysis was performed to set the suitability and weight of the derived indicators(draft). The derived indicators(draft)were applied on 18 routes(49 sections)to produce improvement plans, and on 4 routes(9 sections) to assess suitability. As a result, five assessment criteria (grade, distance, tread condition, width, and sign) and application standards were created. Subsequently, 5 levels (from level 1 “very easy” to level 5 “expert”) were invented based on the total score (15 to 51) which was calculated by multiplying application standard for each criteria by weight. After applying those on the fields, the average was calculated to be 24.2±8.9 points (11∼43 points), while the sum of “very easy”, “easy”, and “intermediate” accounts for more than 90%. Since there was no level lower than expected from the field survey or “expert” section, the standard of the existing calculation formula was adjusted to be equally spread. Therefore, a new formula was created after suitability assessment. After re-applying the new formula on the assessment result of the field application, it was found that “intermediate” decreased by 9%, “advanced” increased by 9%, and “expert” increased by 3%. The results of this study are expected to be employed as basic data for assessing difficulty level of forest trail.

본 연구는 숲길 이용난이도 등급을 구분하는 평가항목 및 등급 구분기준을 제시하고자 수행되었다. 국내·외문헌조사를 통해 평가항목 및 적용기준을 도출하였으며, 도출된 지표(안)의 적합성과 가중치 설정을 위해 AHP 기법을 적용하였다. 도출된 지표(안)을 18개 노선(49개 구간)에 현장적용하여 개선안을 도출하였으며, 개선안을 4개노선(9개 구간)에 적용하여 적합성을 평가하고 확정하였다. 그 결과 구간경사도, 구간거리, 노면상태, 노면폭, 안내표지 유무 등 5개의 평가항목과 적용기준을 도출하였으며, 각 항목별 적용기준에 가중치를 곱한 값을 더한 총점(15 점~51점)을 분할하여 1등급(매우쉬움), 2등급(쉬움), 3등급(보통), 4등급(어려움), 5등급(매우어려움)으로 이용난이도 등급을 구분하였다. 현장적용 결과 평균 24.2±8.9점(11~43점)으로 도출되었으며, 매우쉬움, 쉬움, 보통의 합계가90% 이상으로 나타났다. 현장조사 의견보다 낮은 등급으로 도출되거나 매우어려움 구간이 부재함에 따라 기존식의 점수합계 기준을 균등분할로 조정하였고, 적합성을 평가하여 개선식을 도출하였다. 개선식을 현장적용 평가결과에 재적용한 결과 보통 약 9% 감소, 어려움 약 9% 증가, 매우어려움이 약 3% 증가하였다. 본 연구결과는 숲길 이용난이도 등급 산출 시 기초자료로 활용될 것으로 기대된다.
