교량형 버티포트 계획 연구

Abstract

This study is to propose a Vertiport design using an overpass and a Han River bridge among unused spaces in the city. In modern cities, as the population and demand for private cars increase in limited spaces, traffic congestion costs by year increase, resulting in waste of transportation and time costs. Urban Air Mobility (UAM), a next-generation aviation mobility that can fly over the air with low noise, is recognized and in the spotlight as a way to solve traffic congestion. However, in the case of UAM, the development of Vertiport, an infrastructure structure for boarding, charging, and management, is also being discussed at the same time because it can only take off and land in a dedicated vertipad space. In addition, Vertiport needs to identify and plan various factors such as demand, transportation facility connection, and safety in selecting a location, so it is necessary to look at its location from a complex perspective. In this study, we analyzed the regulations and standards of vertiport established by each institution to design vertiport, and compared the cases of vertiport abroad, it was difficult to secure a large site as large as a vertiport space abroad, so it was considered an advantageous idea to develop vertiport through an unused space in the city. Considering the location selection factors such as demand, transportation facility connection, and safety among unused spaces in the city, existing vehicle users, buses, and water taxis can be used, and 'overpasses and Han River bridges' that can be less affected by noise problems and the surrounding environment are considered suitable. Among them, the overpasses and Han River bridges within a 1km radius of the K-UAM demonstration route were selected, and the previous location conditions were analyzed in detail to derive a target site that could actually be designed by vertiport. There is no superstructure among the target sites, and Hannam Bridge, which is advantageous in designing vertiport in terms of scale and traffic demand, was selected and a vertiport prototype was proposed. In order to increase the connection of transportation facilities, the existing water taxi deck and bus stop were relocated to be developed in combination, and rapid transportation transfer was possible through a vertical core. Through this design plan, the unused space of the overpass and Han River bridge will be reconsidered as a possible three-dimensional space as a vertiport location, and at the same time, it will be used as basic data necessary for future vertiport development.
