However, the relationship between air cargo transportation and international trade has been neglected. This study contributes to the literature by focusing on the relationship between these variables in a large country sample group. The aim of this study is to examine the multidimensional relationship between air freight transportation and international trade. In the study, international trade (ME) and air cargo (AC) data for 127 countries are analysed for the period 2000–2021. In the study, cointegration tests and short and long run causality tests were used to identify the relationship between variables. Pedroni cointegration test results indicate that AC may have an impact on ME in the long run. In addition, according to the results of the study, the effect of ME on AC is significant in the short run. Dumitrescu and Hurlin (2012) panel Granger causality test results find evidence of homogeneous bidirectional causality from AC to ME and from ME to AC. In country-by-country analyses, there is causality from ME to AC in 7 countries from Africa, 7 from Asia, 2 from Europe, 2 from Europe, 9 from the Americas and 2 from the Middle East. Causality towards ME was statistically detected in 9 countries from Africa, 8 from Asia, 10 from Europe, 3 from America and 2 from the Middle East. Bidirectional causality is found in 3 countries from Africa, 2 from Asia, 2 from Europe, 2 from Europe, 3 from America and 1 from the Middle East.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"125 ","pages":"Article 102778"},"PeriodicalIF":3.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143592714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forecasting aircraft noise with high accuracy is of high importance for helping attempts regarding noise mitigation, which is an important concern for people living in the environment of the airports. In this study, the noise of commercial aircraft is predicted for lateral, flyover and approach points based on maximum take-off mass (MTOM), maximum landing mass (MLM) and engine take-off thrust. For this study, the data of more than 12000 is filtered to 3528 due to existing repeated data and the prediction is performed by employing two machine learning methods such as Random Forest (RF) and Long Short-Term Memory (LSTM). Moreover, the analysis of feature importance is carried out for three cases where the modeling is established. According to analysis results, noise is predicted with between about 0.96 and 0.97 of R² through three points by RF where mean absolute error (MAE) changes 0.043–0.049. On the other hand, LSTM achieves noise modeling with higher accuracy, which provides more than 0.99 of R². Namely, MAE is obtained to change between 0.0085 and 0.023 for all phases. Lastly, MTOM has the highest importance for prediction of noise with 82.58%–94.48% whereas it is followed by engine take-off thrust, which has 12.5% importance at flyover phase. This study shows that aircraft noise can be forecasted with relatively low model error using three known specifications of any aircraft-engine pairing. To predict aircraft noise with high accuracy helps the designers to observe the effects of changes in aircraft weight and power of the engine on aircraft noise due to the retrofitting of new technologies.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"125 ","pages":"Article 102779"},"PeriodicalIF":3.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143592712","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}

The results illustrate that the air transport network exhibits persistent small-world properties and increasingly cohesive core-periphery structure. After controlling for the impacts of network structure and other characteristics, the results illustrate that the network tie formation is most strongly driven by economic and population scales, followed by geographical centrality, and finally by economic and population growth rates. Although the effects of economic and population growth rates are relatively weak, they exhibit distinct strengthening trends over time. The results further provide evidence that these effects do not operate in isolation. While the effect of geographical centrality generally strengthens the economic and population effects, the effects of economic and population scales substitute each other, and the scale- and growth-rate-related effects strengthen each other. With a deepened understanding of the dynamic associations between air transport systems and socioeconomic contexts, the findings offer implications for more equitable and efficient socioeconomic development through strategic inter-city air transport network planning.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"125 ","pages":"Article 102764"},"PeriodicalIF":3.9,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143578872","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}

In the second step, a suitable spatial measurement model was determined using the Lagrange multiplier, likelihood ratio, Hausman, and Wald tests to evaluate direct and spillover effects of infrastructures of airports, economic activities of cities as well as spatial weight matrix between airports and cities on airport PT, providing an unambiguous basis for policy formulation and testing. The main findings prove that the urban economic and demographic growth directly influences PTs of the local airport and those in neighboring cities.

This is especially the case for the transportation of goods. Using UAM for cargo operations is likely through operating on Middle-Mile Delivery (MMD) missions to transport cargo between facilities or distribution centers in an operator’s network. The efficiency and practicality of such a network are largely affected by the selection of strategic positions for vertiports. As vertiport location optimization is underexplored in current scientific research this paper aims to fill this research gap by developing and analyzing a multi-objective optimization model for the placement of vertiports for a middle-mile package delivery system, considering capacity, available land space, safety and noise impact factors. We develop a novel Multi-Objective Multiple Allocation Capacitated p-Hub Coverage Problem framework for an MMD UAM network and test it using the South Holland region as a case study. Notably, the model can easily be converted to other cities. First, to reduce computational efforts, the K-means clustering algorithm is proposed. This is used to divide 6625 zones into a number of K clusters, with each cluster representing a vertiport candidate location. Furthermore, we present a multi-objective Tabu Search based heuristic optimization algorithm to solve the optimization problem. The impact of different factors such as number of clusters, number of vertiports, drone range, maximum safety distance, and turn around time The presented model provides decision-makers with the ability to assess the suitability of a region for the implementation of a UAM MMD system and aids in the identification of potential good locations to set up vertiports. We demonstrate that an increase in the number of vertiports leads to a higher attainable demand coverage, however, this results in a steep drop-off in terms of safety and noise nuisance performance. Furthermore, the results show that an increase in drone range, maximum safety distance or a decrease in turn around time allow for overall better performing vertiport networks.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"125 ","pages":"Article 102757"},"PeriodicalIF":3.9,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143487762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
