The key to the successful implementation of this transition lies in the development of efficient electric vehicle dispatching models that comprehensively consider the charge-discharge processes of electric vehicles. However, due to the nonlinear characteristics of charge-discharge processes, finding precise solutions poses a significant challenge. Previous researchers have often used traditional energy consumption models and constant charging rates to simplify calculations, but this has resulted in inaccurate estimates of the remaining battery charge level. Furthermore, the lack of diverse pacing and charging strategies for airport ground service vehicles necessitates more adaptable solutions to enhance operational efficiency. To address these challenges, this paper uses airport electric tractors as a case study, develops an accurate model that takes into account the start-stop process and a piecewise linear charging function, designs an improved genetic algorithm that incorporates a greedy algorithm and an adaptive strategy, and develops charge-discharge coupling strategies for different configuration scenarios at Nanjing Lukou Airport to meet current and future needs. The research results indicate that compared to traditional genetic algorithms, the proposed improved genetic algorithm significantly enhances solution accuracy and convergence speed. Additionally, with the increase in flight scale, airports can appropriately enhance their charging strategies; airports with dispersed aircraft stands should devise higher pacing strategies compared to those with dense aircraft stands.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"124 ","pages":"Article 102733"},"PeriodicalIF":3.9,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Air corridors are longish airspace volumes, where multiple self-separated aircraft fly sequentially without instructions from the Air Traffic Controllers (ATCOs). However, due to high traffic volume and limited inter-distance between aircraft, the trailing aircraft becomes more conflict sensitive to environment changes (for instance, a sudden deceleration in the preceding aircraft). Therefore, to realize high traffic throughput while maintaining operation safety, an enhanced multi-attribute decision making (MADM) framework is presented in this paper to address the need for appropriate maneuver determination in a close proximity situation. Specifically, we decompose the MADM scheme into two main steps. In the first step, four candidate maneuver options are generated under different self-separation methodologies. Each candidate option is then evaluated via multiple attributes, which represent various performance objectives of the aircraft. In the second step, the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used to determine the optimal maneuver that realizes an adequate tradeoff among the competing objectives. By simulating aircraft maneuvers in diverse emergency scenarios and with various corridor traffic settings, experimental results have successfully demonstrated the effectiveness of the proposed MADM-based self-separation mechanism.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"124 ","pages":"Article 102721"},"PeriodicalIF":3.9,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alleviating traffic congestion in metropolitan areas has been a persistent challenge for decades, leading to increased interest in aerial mobility solutions. Recent advancements in distributed electric propulsion, battery technology, and autonomous navigation have made electric vertical take-off and landing (eVTOL) aircraft a feasible option for intercity transport. For efficient UAM systems, we optimize the high-level planning of UAMs, i.e., determine the numbers of eVTOLs, vertiport spaces, and chargers, together with lower-level operations to control each eVTOL's operational state between in-service, charging, idling, and relocating. Accounting for spatio-temporal demand and cost heterogeneity, we formulate the UAM optimization framework as a mixed-integer programming problem. In our numerical study, we analyze a scenario involving three hypothetical vertiports in the Seoul Metropolitan Area, South Korea. The results reveal relationships between the optimal solution and several exogenous factors critical to eVTOL operations, including the targeted level of service for users and eVTOL charging speed.

We provided six scenarios composed of a combination of experimental attributes (travel time, travel cost, and transfer frequency) for five alternative transport modes (airport train, airport bus, taxi, passenger car, and UAM) to each respondent and asked them to choose one most preferred mode in each scenario. A mixed multinomial logit model was used to consider the underlying characteristics of the collected data.

People who have higher incomes, frequently use taxis, and want to arrive at airports quickly before boarding are more likely to take UAM for airport access. The findings imply that UAM may be able to become a kind of taxi service operating in the sky, but its expensive fares may discourage its popularization.
