Abstract

This paper presents an analysis of door design for the Ui LRT based on experiments to predict doorway flow-time and their analyses results. A similar railway vehicle (from Gimhae LRT) and operational conditions are utilized to assess the doorway flow-time through repetitive experiments. Design of the experiments consists of four scenarios, and the experiments are repeated 39 times in total. We use the results of the experiments to verify the design of doors of Ui LRT (e.g. the required number of doors and their width). Various statistical analyses are carried out for the flow-time with respect to the number of boarding/alighting passengers. We make three category levels of boarding/alighting passengers, and analyze the mean and variance for each category, and then carry out One-Way ANOVA to analyze how the number of boarding/alighting and onboard passengers impact flow-time. The results of this paper can be used for making decisions about doors of the LRT vehicle.

본 논문은 서울시 우이-신설 경전철의 출입문 사양 결정을 위한 승하차 시간 예측 모의실험 내용과 실험 데이터 분석결과를 제시한다. 우이-신설 경전철과 유사한 차량(김해 경전철 차량) 및 운영조건을 설정하여 승하차 시간을 측정하는 모의실험을 반복적으로 실시한다. 실험계획은 승하차 인원의 시나리오에 따라 4가지로 구성하였으며, 총 39회의 모의실험을 실시하였다. 이 실험결과를 활용하여 우이-신설 경전철의 출입문 폭과 수량에 대한 차량설계 방안의 적절성 검증이 가능하였다. 실험결과에 대한 통계적 분석으로 승하차 인원의 변화에 따른 승하차 시간 분석을 실시하였다. 실험계획에서 설정된 시나리오를 승하차 인원의 규모에 따라 다시 3가지 수준으로 분류하고, 수준별 승하차 시간의 평균과 분산을 조사하였다. 다음 승차, 하차 및 재차 인원의 구성에 따른 일원배치 분산분석(One-Way ANOVA)을 실시하여 각각의 구성이 승하차 시간에 미치는 영향을 분석하였다. 본 논문에서 제시된 실험결과 및 분석결과들은 장래 도시형 경전철 차량의 출입문 설계 관련 업무에 활용될 수 있을 것으로 판단된다.
