“…Since the vertiport describes a significant bottleneck especially for near-term UAM applications, a vertiport's performance, operational capability and resilience are of great interest. In HorizonUAM, the vertiport is being examined in terms of regulatory and operational state of the art [60], exemplary layout designs and corresponding concept of operations for both low-and high-density throughput scenarios [61], performance-based rating of a vertiport's airside operation [62] and a vertiport's placement inside airport environment [57]. Furthermore, a vertiport network in an urban environment was developed and compared to ground-based traffic networks [37] and the development and validation of real vertiport prototypes and their operation inside a scaled urban environment suitable for flight testing [63] is envisaged.…”

Urban air mobility is a rapidly growing field of research. While drones or unmanned aerial vehicles have been operated mainly in the private and military sector in the past, an increasing range of opportunities is opening up for commercial applications. A new multitude of passenger-carrying drone or air taxi concepts promises to fulfill the dream of flying above congested urban areas. While early research has been focusing on vehicle development, solutions for urban air traffic management are lagging behind. This paper collects and reviews the main findings of past urban-air-mobility-related research projects at the German Aerospace Center (DLR) to serve as a basis for ongoing research from an air traffic management perspective.

“…In this paper, we build on the initial performance evaluation presented in [14] and add potential operational uncertainties to the vertidrome operation. In this context, we evaluate how demand/capacity ratio variations, short-term disruptions of pad and gate availability, stochastic deviations of service times, and VALoS performance target variations impact the performance of the airside traffic flow and the achieved VALoS.…”

“…The developed Vertidrome Airside Level of Service (VALoS) concept, its origin, and introductory application were first presented in [14] at the 2021 AIAA Aviation Forum. The following two Sections 2.1.1 and 2.1.2 present a revised summary of [14] to support the overall understanding of this paper and the results presented in Section 3.

“…Contributing to a performance-based vertidrome design approach, the Vertidrome Airside Level of Service (VALoS) concept, the basis of the VALoS framework first published in [14], targets the performance evaluation of future vertidrome airside operations from a capacity and efficiency perspective. For our analysis, we specifically focus on the airside system boundary of an individual vertidrome since it describes a fundamental part by linking airspace and landside performance.…”

This paper presents the Vertidrome Airside Level of Service (VALoS) framework, a novel performance metric designed to evaluate airside traffic flow operations at vertidromes in the context of Urban Air Mobility (UAM). As the UAM industry rapidly evolves, the need for a comprehensive evaluation framework becomes increasingly important. The VALoS framework provides a performance-based approach to evaluating vertidrome traffic flow performance, considering metrics like average passenger delay, air taxi in-flight delay, and vertidrome punctuality. Unlike existing Level of Service approaches, the VALoS framework unifies the requirements of various stakeholders, the passenger, the air taxi operator, and the vertidrome operator each with their own performance metric and target. It provides a multi-faceted approach covering airside air and ground traffic flows, arrivals and departures, and performance changes during strategic planning and tactical execution phases. The VALoS is evaluated at 15-min intervals while considering changing stakeholder performance targets and operational uncertainties. For the reference use case, the study demonstrates the significant impact of short-term disruptions, while stochastic deviations can be neglected. Higher traffic volumes due to changing demand/capacity ratios result in higher VALoS variability. The VALoS framework, together with a fast-time simulation, provides a versatile method for exploring future vertidrome traffic flows and supporting strategic vertidrome airside planning and integration. This integrated approach is essential for the evolving UAM vertidrome industry; aligning the interests of different stakeholders and promoting sustainable and efficient vertidrome planning and operation.

“…A performance-based evaluation of a vertiport's airside traffic flow was conducted by [156]. For that purpose, a UAM tailored vertidrome airside level of service VALoS concept was developed in order to identify how well a specific vertiport setup can process a particular demand distribution based on a distinct vertiport layout, airside operational concept and emerging airside traffic flow.…”

Novel electric aircraft designs coupled with intense efforts from academia, government and industry led to a paradigm shift in urban transportation by introducing UAM. While UAM promises to introduce a new mode of transport, it depends on ground infrastructure to operate safely and efficiently in a highly constrained urban environment. Due to its novelty, the research of UAM ground infrastructure is widely scattered. Therefore, this paper selects, categorizes and summarizes existing literature in a systematic fashion and strives to support the harmonization process of contributions made by industry, research and regulatory authorities. Through a document term matrix approach, we identified 49 Scopus-listed scientific publications (2016–2021) addressing the topic of UAM ground infrastructure with respect to airspace operation followed by design, location and network, throughput and capacity, ground operations, cost, safety, regulation, weather and lastly noise and security. Last listed topics from cost onwards appear to be substantially under-represented, but will be influencing current developments and challenges. This manuscript further presents regulatory considerations (Europe, U.S., international) and introduces additional noteworthy scientific publications and industry contributions. Initial uncertainties in naming UAM ground infrastructure seem to be overcome; vertiport is now being predominantly used when speaking about vertical take-off and landing UAM operations.
