A traffic engineering model for air taxi services

Transportation Research, Part E: Logistics and Transportation Review, 2008
Abstract We propose a single-provider model for on-demand air taxi services. Data from a discrete-event model support a “flow model,” which describes the aggregate flow of passengers and aircraft for an air taxi service provider without specifying event-level operation. Using a set of hypothetical scenarios for air taxi network operation, we evaluate

Noise prediction for urban air taxi operation

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2021
Solutions to escape crowded streets are increasingly taking up new forms of mobility. This also includes air taxis or VTOLs. In addition to passenger traffic, suggestions, such as parcel delivery by drones, are also regularly part of future visions. Air taxis pose additional safety requirements due to the transport of people and they also represent a ...

Urban Air Mobility: Projections for Air Taxis

International Journal of Innovation and Technology Management, 2021
The growing global demand for efficient and sustainable urban mobility in metropolitan areas has created innovative approaches to new modes of transportation and vehicles. Using the Delphi method, this study explored the prospective development of urban air mobility (UAM), specifically the emergence of air taxis or vertical take-off and landing (VTOLs)
