Abstract

Urban air mobility (UAM) extends urban transportation to low-altitude airspace using electric vertical take-off and landing (eVTOL) vehicle to reduce traffic congestion. The vertical take-off and landing (VTOL) site connecting ground and air transport is the critical infrastructure of the UAM. Determining its locations is essential for the design and operation of the air route. This study focuses on the problem of the location of the VTOL site, using Shenzhen as the study area, and establishes an integer programming model with the objective of maximizing travel cost savings to identify the optimal locations of the VTOL sites. This study is different from existing ones in that it explicitly considers the three-dimensional spatial availability of VTOL sites. Geographic information system (GIS) tools are used to identify locations that satisfy two-dimensional (2D) planar availability, and an obstacle assessment model of the approach/departure and transitional surfaces of the VTOL site is built to further screen the locations. The selected potential sites are used as input to the integer programming model, ensuring that the locations identified to establish the VTOL site are optimal. The impact of the number of VTOL sites, the user's transfer time at the VTOL sites, and the eVTOL pricing on the model solution is also discussed. Although this study uses Shenzhen as a research object, the proposed methodology is generalized and applicable to any other city or region, providing recommendations and references for initial planning and related operations of the UAM in selected areas.

考虑到进场和离场时的障碍物清除情况,确定 VTOL 场址位置
城市空中交通(UAM)利用电动垂直起降(eVTOL)飞行器将城市交通扩展到低空空域,以减少交通拥堵。连接地面和空中运输的垂直起降(VTOL)场地是城市空中交通的关键基础设施。确定其位置对于空中航线的设计和运营至关重要。本研究以深圳为研究区域,重点关注垂直起降点的选址问题,并建立了一个整数编程模型,以最大限度地节约旅行成本为目标,确定垂直起降点的最佳位置。与现有研究不同的是,本研究明确考虑了 VTOL 场址的三维空间可用性。使用地理信息系统(GIS)工具来确定满足二维(2D)平面可用性的地点,并建立 VTOL 场址的进场/离场和过渡表面的障碍物评估模型,以进一步筛选地点。选定的潜在地点将作为整数编程模型的输入,确保确定的 VTOL 场址是最佳地点。此外,还讨论了 VTOL 站点数量、用户在 VTOL 站点的换乘时间以及 eVTOL 定价对模型解决方案的影响。虽然本研究以深圳为研究对象,但所提出的方法具有普适性,适用于其他任何城市或地区,为选定地区的无人机空中作业区的初步规划和相关运营提供建议和参考。
