Summary: The study aims to explore the distribution of benefits from urban air mobility (UAM) considering spatial dimension and differential impacts on low- and high-skilled households. It proposes a framework for assessing welfare impacts resulting from the introduction of novel transport modes and conducts analysis using an urban spatial computable general equilibrium model. Incorporating different skill levels of households allows for examining location choice and travel behavior, while simulations highlight the decisive impact of UAM features on modal choice and welfare effects.

Summary: Urban air mobility (UAM), a new transportation system expanding urban mobility from 2D to 3D, has gained worldwide attention. This study proposes a balanced branch queuing approach (BBQA) model based on the BQA model to improve operational efficiency in UAM and verifies its effectiveness through simulation. The BBQA model achieves identical airspace safety as the BQA model and outperforms the SBA model in on-time performance (OTP). The proposed vertiport airspace blueprint concept and approach control model are expected to contribute to future air traffic management research in UAM.

Summary: This paper systematically selects, categorizes, and summarizes existing literature on UAM ground infrastructure, aiming to support the harmonization of contributions from industry, research, and regulatory authorities. The study identifies various research topics related to UAM ground infrastructure, such as airspace operation, design, location and network, throughput and capacity, ground operations, cost, safety, regulation, weather, noise, and security. It also discusses regulatory considerations and highlights significant scientific publications and industry contributions. The paper concludes that there is a need for more research in certain areas, particularly cost, safety, regulation, weather, noise, and security. The paper notes that the naming of UAM ground infrastructure has become more standardized, with "vertiport" being predominantly used for vertical take-off and landing UAM operations.

Summary: Urban air mobility (UAM) is revolutionizing urban transportation through the development of electric vertical take-off and landing (eVTOL) vehicles. However, the success of UAM relies on market demand, which lacks systematic reviews on demand analysis. To address this gap, we conducted a comprehensive review of existing literature on demand analysis for UAM. Our review identified the demand for UAM in various applications and the factors influencing market demand. We also explored qualitative and quantitative methods for demand analysis and discussed the role of market demand in the UAM life cycle. Finally, we highlighted opportunities for future research related to demand analysis for UAM.
