Abstract

This Study estimates the actual night traffic using the smart card data used by most of the public transportation users, and compares it with the current night bus routes by KT Telecom based on the night time call volume. In order to compare the current night bus and night trips evaluated by smart card data, we presented indicators related to the degree of matching, and estimated the volume of service currently provided. The unique approach of the study is that we chose subway station instead of bus stop for the unit of the study. Bus stops has their complexity in a way that stops with same name could belong to different administrative area depending on its direction. For this reason, we decided to use subway station and defined its adjacent administrative district as the scope of influence. Since night bus is the primary means of transportation during the late night, it is anticipated that they will be able to provide better service by calculating the actual traffic and selecting the routes.

본 연구에서는 대중교통 이용객의 대부분이 사용하는 스마트카드 자료를 이용하여 실제 심야시간 통행량을 추정하고, 이를 현재 심야버스 노선과 비교하여 KT통신사에서 심야시간에 발생한 통화량을 기준으로 선정한 심야버스 노선과 실제 심야통행량을 비교하였다. 심야버스와 심야통행량을 비교하기 위해 일치도와 관련된 지표를 제시하고, 현재 얼마나 서비스가 제공되고 있는지 계산하였다. 연구의 특이한 점은 같은 정류장명을 가진 버스정류장이라도 어느 방향에 있느냐에 따라 속한 행정동이 다르기 때문에, 기준이 되는 영향권의 지표를 지하철역으로 잡고, 지하철역과 인접한 행정동을 지하철역의 영향권의 범위로 설정한 것이다. 심야버스가 심야시간 주요 교통수단으로 자리 잡은 만큼, 실제 교통량을 계산하여 노선을 선정한다면, 더 나은 서비스를 제공할 수 있을 것으로 기대된다.
