버스노선정보를 이용한 교통수요분석용 전국버스네트워크 구축

Abstract

Currently, the travel demand forecasting networks of roads and railroads in Korea were installed, but the bus network has not been established except the metropolitan area. It is very ironic that no bus network for travel demand forecasting has been established at the present time, when it is possible to grasp the bus operation status in real time using the smartphone in most regions of the country. This is also because bus route information data built by portal sites or transportation card settlement companies cannot be used directly for travel demand forecasting. In this study, the nearest node of the stop (trajectory) coordinate was searched using the existing bus route information data. By searching for the shortest route between the searched nearest nodes and constructing a link list, a nationwide bus network for travel demand prediction was established. Due to the difference in the location of the nearest node and the actual bus stop (trajectory), complete automatic search is difficult, but the initial bus network construction is expected to be possible. We compared the demand prediction results using KTDB's bus OD, which is currently distributed for travel demand prediction, and the volume of bus traffic using route information, and checked the difference.
