Data-driven future demand forecasting for UAM

As the public interest of UAM* is getting higher and the underlying technology for UAM becomes sophisticated, the need to forecast the future demand of UAM increases. As the data-driven demand forecasting method has become more accurate than the traditional modeling-based forecasting method, TRUE lab utilized Seoul taxi GPS data to forecast the potential demand for UAM. Our assumption is based on the idea that part of the long-range taxi trip will be replaced by the emerging mobility service - UAM. As our first step toward UAM demand forecasting, we considered the case of using existing helipads. We plan to expand our scope in future work to UAM routing, fleet rebalancing and scheduling.

Traffic Data Representation: Resolutions and Structures

Air Route Network as Complex Network

Air traffic carried by three major countries in Northeast Asia have significantly increased in the past decade. In contrast to the growing importance, there exist few regional studies on the characteristics of the Air Transport Network (ATN). ATNs have been researched over a couple of recent decades by modeling them as airport networks. Airport networks as virtual networks of directly connected airport pairs essentially model airline service network to exclude the airspace, where most of the operational resources are consumed. In this study, air route network robustness of the rapidly growing Northeast Asian region is assessed based on the node criticality.
