![]() A discrete-event simulation model is developed to simulate a full day of commuter operations at the San Francisco Financial District's busiest vertiport. The study included in Chapter V focuses on analyzing factors impacting vertiport capacity. ![]() Therefore, operational efficiency is critical for capturing maximum UAM demand with limited vertiport size. However, vertiport size could be limited due to land availability and high infrastructure costs in CBDs. A heavy concentration of UAM demand is observed in specific areas such as Central Business Districts (CBD) during the spatial analysis of estimated UAM demand. UAM vertiport capacity may be a barrier to the scalability of UAM operations. The former study is published in the AIAA Aviation 2021 Conference proceeding, and the latter is published in ICNS 2021 Conference proceedings. ![]() Mode-choice conditional logit models are calibrated from the survey data, further used to estimate UAM demand. Both studies utilize the latest available originating passenger survey data to understand arriving passengers' mode-choice behavior at the airport. Chapter III and Chapter IV focus on developing the UAM Concept of Operations (ConOps) and demand estimation methodology for airport access trips to Dallas-Fort Worth International Airport (DFW)/Dallas Love Field Airport (DAL) and Los Angeles International Airport (LAX), respectively. In an effort to analyze the feasibility of UAM operations in different use cases, demand estimation frameworks are developed to estimate UAM demand in the airport access trips segment. This study was published in Transportation Research Part A: Policy and Practice journal. The feasibility of commuter UAM operations in Northern California is further analyzed through a series of sensitivity analyses. An integrated demand estimation framework is developed utilizing the calibrated mode-choice model to estimate UAM demand and place vertiports. A mode-choice model is calibrated from the commuter mode-choice behavior observed in the survey data. urban areas.Ĭhapter II presents a methodology to estimate commuter demand for UAM operations in the Northern California region. The studies presented in this dissertation primarily focus on analyzing urban travelers' current behavior using revealed preference data and estimating the potential UAM demand for different trip purposes in multiple U.S. The success of UAM depends on its operational efficiency and the relative utility it offers to current travelers. While the industry is preparing to introduce this revolutionary mode in urban areas, realizing the scope and understanding the factors affecting the attractiveness of this mode is essential. UAM is a concept aerial transportation mode designed for intracity transport of passengers and cargo utilizing autonomous (or piloted) electric vehicles capable of Vertical Take-Off and Landing (VTOL) from dense and congested areas. “Through this pilot project, we are bringing Volkswagen’s long tradition of precision engineering, design, and innovation to the next level, by developing a premium product that will serve the vertical mobility needs of our future tech savvy Chinese customers.” Stephan Wöllenstein, CEO of Volkswagen Group China.This dissertation comprises multiple studies surrounding demand estimation, feasibility and capacity analysis, and environmental impact of the Urban Air Mobility (UAM) or Advanced Air Mobility (AAM). Volkswagen said that as the project develops, the company will work with the relevant Chinese authorities to achieve certification. They have been supported by Chinese partners including Hunan Sunward Technology, a company specialized in aviation product development. To develop the vertical mobility project, Volkswagen formed a team of young local experts. In its final future iteration, the eVTOL could eventually carry four passengers plus luggage over a distance of up to 200km. The company will conduct several flight tests later this year to optimize the concept and an improved prototype will undergo further advanced test flights by late summer 2023. With a luxury x-wing configuration of 11.2m in length and a span width of 10.6m, the model features eight rotors for vertical lift and two propellers for horizontal flight. The vehicle, also known as the Flying Tiger, is the result of a project launched at its China facility in 2020 to explore new mobility solutions, including Urban Air Mobility (UAM). Volkswagen unveiled the V.M.O., the first eVTOL from the traditional German carmaker.
