“…The first is a "ground" taxiway where aircraft equipped with wheels are either self-propelled or tugged along a hardened surface. The second is a "hover" taxiway (also referred to 5 https://s3.amazonaws.com/uber-static/elevate/Summary+Mission+and+Requirements.pdf as an "air" taxiway) where a hover-capable aircraft may move above the surface with a recommended "wheel/skid height of 1 to 5 feet and at a ground speed of less than 20 knots" [18].…”

“…U 2 acceptance [4]. Georgia Tech developed an integer programming approach to determine optimal vertiport placement based on customer demand [5] and also identified substantial siting opportunities for STOL infrastructure with runways of 300 ft or less in the Miami metropolitan area [6]. MIT corroborated significant opportunity for UAM infrastructure on rooftop facilities if footprints of less than 300 ft could be achieved [7].…”

This study develops an Integer Programming (IP) approach to analytically estimate vertiport capacity envelopes. The approach is used to determine the sensitivity of vertiport capacity to the number and layout of touchdown and liftoff pads, taxiways, gates, and parking pads (i.e. the vertiport topology). The study also assesses the sensitivity of vertiport capacity to operational parameters including taxi time, turnaround time, pre-staged aircraft, and approach/departure procedure independence, among others. Findings indicate the importance of balancing the number of touchdown and liftoff pads with the number of gates to achieve maximum aircraft throughput per vertiport footprint. Furthermore, simultaneous paired arrivals or departures provide significant throughput gains without the need for fully independent approach and departure procedures. The methodology and findings introduced in this paper support the development of concepts of operation to maximize throughput for a given vertiport footprint and demand scenario. While throughput has been extensively researched for fixed-wing operations, little research has been dedicated to the operation of infrastructure for Vertical Takeoff and Landing (VTOL) aircraft. The emergence of new VTOL aircraft to conduct a potentially large number of urban air mobility operations creates a need to better understand the operation and throughput capacity of vertiports, especially in space constrained inner-city locations. This paper reviews numerous existing heliport designs to derive four topology classes of vertiport layouts. The IP formulation of vertiport operations is readily adapted to represent the infrastructure and operations of these layouts.

“…8 The first two are intra-city hops with short trip distances. Daskilewicz et al 21 analyzed the range requirement for daily commutes in San Francisco and Los Angeles areas and found that most trips are under 50 km and only a few trips exceed 100 km. Husemann et al 22 studied the UAM demands in the Upper Bavaria district, Germany, and found that most trips are between 10-25 km.…”

“…The input of the selection includes a set of candidate vertiports (usually generated by clustering algorithms [4], [5], [6]) and the budget of the total number of vertiports. The output of the selection is a set of selected vertiports that optimizes certain performance metric of the air transportation network supported by the selected vertiports, such as the savings in total travel time [7] and the package demand served by the aircraft [8].…”

Urban Air Mobility is a concept that promotes aerial modes of transport in urban areas. In these areas, the location and capacity of the vertiports-where the travelers embark and disembark the aircraft-not only affect the flight delays of the aircraft, but can also aggravate the congestion of ground vehicles by creating extra ground travel demands. We introduce a mathematical model for selecting the vertiports location and capacity that minimizes the traffic congestion in hybrid air-ground transportation networks. Our model is based on a mathematical program with bilinear equilibrium constraints. Furthermore, we show how to compute a global optimal solution of this mathematical program by solving a mixed integer linear program. We demonstrate our results via the Anaheim transportation network model, which contains more than 400 nodes and 900 links.
