“…Due to the mobility revolution, urban transport faces issues like emission reduction, congestion, and noise pollution. While alternatives to road vehicles, such as metro systems [2,12] and shared bicycles [13,14], and optimization of the existing road vehicle operations through intelligent traffic signal systems [15,16] have been proposed, these ground-based solutions face constraints due to the saturation of urban surface and underground spaces [1,6]. Few studies fundamentally solve the limitations of ground transportation space.…”

“…Moreover, the capabilities of emergency services, such as medical rescue and fire-fighting, are also compromised by congested roads [1]. According to a report by the Texas A&M Transportation Institute, traffic congestion in the United States caused an estimated 8.8 billion hours of delay and 3.3 billion gallons of wasted fuel in 2019, resulting in a total cost of USD 179 billion [2].…”

Urban air mobility (UAM) enabled by electric vertical take-off and landing (eVTOL) aircraft presents an innovative transportation system for mega-cities. An analysis of the techno-economic feasibility of eVTOL air taxis can provide insights into the development and potential impacts of this emerging mobility solution. This study examines eVTOL configurations and proposes a conceptual model for eVTOL air taxi services. A generic cost–revenue model is developed to evaluate the economic feasibility using the rate of return-on-investment approach. Two critical parameters are identified—maximum voyage and price per kilometer. The modeling analysis shows that eVTOL air taxis can achieve a positive rate of return given realistic assumptions on the critical parameters. Reductions in operating costs and increases in maximum voyage range improve financial viability. With technological advancement, eVTOL air taxis are expected to transform urban transportation by increasing capacity and flexibility. The techno-economic analysis provides useful implications for urban planning and policy regarding this innovative mobility mode.
