초록

본 연구는 보행자도로의 서비스수준 산정방법을 개선하는 것으로 보행점유공간을 주 척도로 하고 기존의 방법에서 고려되지 않았던 양방향 보행류에 따른 상충개념을 도입하여 분석을 하였다. 분석 시 보행상충 공간을 산정하였으며, 방향별 보행자 수에 따른 상충공간과 평균보행시간을 산정하였다. 그리고 시간흐름에 따른 유효보도면적을 산정하여 시공간개념의 보행 점유공간을 통해 서비스수준을 재조정하였다. 산출된 보행점유공간은 0.68상태에서 용량상태를 보이며 이때의 보행교통류율은 80인/분/m로 산정되었고 추가적으로 보행점유공간을 크기순으로 나열하여 기울기가 변하는 지점을 기준으로 서비스수준을 분류하였다. 서비스 수준별 통계적 검증을 수행한 결과 유의수준 5%에서 모든 서비스수준 범주별 유의미한 차이가 있는 것으로 나타났다.

This study describes an improved model for estimating pedestrian LOS (Level of Service) by utilizing the space occupied by pedestrians. The method introduced the concept of conflict along the bi-directional pedestrian flow which enables calculating conflict area and average travel time in walking. Especially, the method incorporates the idea of generalized density concept which can consider effective walking area and pedestrian flow rates that might vary during the analysis period. After establishing methodology, adjustments of pedestrian LOS criteria in term of walking space occupied by pedestrians were performed. As a result, walking-occupied space at capacity level is 0.68 and corresponding pedestrian flow rate was calculated as 80 persons/min/m, while different pedestrian-occupied spaces were ordered to classify LOS at the points where the gradient changes. Furthermore, the statistical verification of service levels has shown that there is significant difference among all LOS categories at 5% significance level.
