Accurate information about the airport's throughput is crucial for monitoring traffic flow, evaluating the development status of aviation industry. In this letter, we used the Suomi National ...Polar-orbiting Partnership-Visible Infrared Imaging Radiometer (NPP-VIIRS) and the Defense Meteorological Satellite Program's Operational Linescan System (DMSP-OLS) nighttime light (NTL) data as effective proxies for evaluating and monitoring the airport's throughput power in China mainland. The results show that there is a significant positive correlation between the NTL intensity and the airport's throughput (<inline-formula> <tex-math notation="LaTeX">R^{2} > 0.85 </tex-math></inline-formula>). The NPP-VIIRS NTL data have been proved to not only distinguish the airport area and nonairport area but also build airport's NTL feature space. This letter reveals that the NTL images provide powerful remote sensing data sources to model the spatiotemporal dynamics of airport's throughput of China mainland at a large spatial scale.
The article is focused on analysis of financial cost effectiveness and the utilization of business premises in the terminal building of Bratislava Airport. Our analysis is based on a comparison of ...sales, profitability, and number of customers of individual newsagents of the GGT a. s. company, which operates three such newsagent stands at the examined airport. Each of the newsagents are located in a different part of the airport terminal, namely Schengen, non-Schengen and check-in area. The examined shops will serve as a practical example of the usability of these areas, and our goal is to find out which of these parts of the Bratislava Airport terminal building is most used by passengers and airport visitors. The data was collected for the period from 1st January 2018 to 31st December 2018, covering one full calendar year, which is a sufficient period for our analysis.
The entire aviation industry was severely hit by the COVID-19 pandemic, leaving airplanes stranded and airports empty of the usual hustle. While the full consequences of this crisis are yet unknown, ...it only adds fuel to the ongoing debates about the future of the aviation sector, including airport capacity and environmental challenges facing many hub airports around Europe. While conventional aviation research describes the development of hub airports as a function of varying geo-economic variables, this research sheds light on the societal underpinnings of the makings of hub airports. From an airport governance perspective, a case study of four European hub airports, representing both expanding and struggling hubs, was conducted. Based on interviews with 31 airport stakeholders from four different countries (i.e. Belgium, Finland, the Netherlands and Switzerland) as well as a review of strategic and policy documents, the authors argue that the development of hub airports and their corresponding governance models is a non-linear process, informed to a great degree by societal and discursive factors. The authors conclude that developing and sustaining a well-functioning hub airport that supports regional development necessitates an active stance from local, regional and national authorities. A clear and strategic governance model is needed, one that is not limited to ownership and regulation questions, but one that guarantees a wide-ranging consensus among airport stakeholders. Finally, the paper provides a perspective on future potentials and challenges facing European hub airports.
Airports are at the forefront of technological innovation, mainly due to the fact that the number of air travel passengers is exponentially increasing every year. As a result, airports enhance their ...infrastructure intelligence and evolve as smart facilities to support growth, by offering an enjoyable travel experience. New challenges are coming up, which aviation has to deal with and adapt to, such as the integration of Industrial IoT (Internet of Things) in airport facilities and the increased use of smart devices from travelers and employees. Cybersecurity is becoming a key enabler for safety, which is paramount in the aviation context. Smart airports strive to provide optimal services in a reliable and sustainable manner, by working around the domains of growth, efficiency, safety and security. This article researches: (a) the implementation rate of cybersecurity measures in commercial airports; (b) malicious threats that evolve due to IoT and smart devices installed; (c) risk scenario analysis for IoT malicious attacks with threat mitigation actions. With the aim to enhance operational practices and develop robust cybersecurity governance in smart airports, we present a systematic and comprehensive analysis of malicious attacks in smart airports, to facilitate airport community comprehend risks and proactively act, by implementing cybersecurity best practices and resilience measures.
To conduct an accurate and reliable airport delay prediction will provide an important basis for the macro control of an airspace delay situation and the dynamic allocation of airspace system ...capacity balance. Accordingly, a method of delay prediction for target airports based on the spatio-temporal delay variables of adjacent airports is proposed in this paper. First, by combining the complex network theory, we first extract the topology of the airport network and create airport clusters with comparable network properties. Second, we develop the TS-BiLSTM-Attention mode to predict the delay per hour for airports in the cluster. As the spatio-temporal feature variables, the arrival delay of airport cluster-associated airports and the delay time series of landing airports are utilized to reach the conclusion. The experimental results indicate that the delay prediction predicated on clusters is superior to that based on data from a single airport. This demonstrates that the delay propagation law derived from cluster data based on spatio-temporal feature extraction can generalize the delay propagation characteristics of airports within clusters.
This paper proposes a methodology based on agent-based simulation to define the new optimum airport level-of-service (LOS) that guides cost-efficient terminal design while providing passengers with a ...reasonable LOS. It aims to allow at least 50% of passengers to experience the new optimum LOS range while cutting off LOS values during peak and off-peak periods. The simulation also helps to adopt the standard cut-off combination and test the applicability of the methodology. The test reveals that the proposed methodology is useful for establishing an alternative LOS standard that is more cost-efficient and flexible than the conventional IATA standard and could be applicable for other public transport terminals.
The Hong Kong International Airport (HKIA) was constructed on a platform mainly reclaimed from the sea. The platform has experienced some significant settlement since its operation in 1998 due mainly ...to consolidation of the materials used in the land reclamation. Although some studies have been carried out to measure the settlement with techniques such as Interferometric Synthetic Aperture Radar (InSAR), the past studies have each only covered some limited time periods. Therefore, a complete history of settlement since the operation of the Airport has never been available to aid the understanding of the spatiotemporal behavior of the land settlement. We attempt for the first time to make full use of most of the available SAR data from multiple SAR sensors (ERS-2, ENVISAT ASAR, COSMO-SkyMed (CSK), and Sentinel-1A) to generate a settlement time series of the HKIA over 1998–2018 with an improved multi-temporal InSAR technique. In order to fill the time gaps between the different SAR datasets, a settlement model is developed based on the InSAR measurements. The results reveal both the spatial and temporal variations of the land settlement. They also show for the first time that the accumulative settlement reaches up to 40 cm over the past two decades. The settlement is largely associated with the material types used in the landfill works and the underlying alluvial sediments as some earlier research has indicated, and the stages of the reclamation works. The results are validated through cross-validation between the datasets and with leveling and GPS measurements on the Airport platform.
•Two decades of land settlement history of HKIA is retrieved for the first time.•Land settlement correlates strongly to landfill materials and reclamation methods.•Research results inform future land reclamation practice.
We investigate how the intensity of competition among airports affects their technical efficiency by computing airports’ markets on the basis of a potential demand approach. We find that the ...intensity of competition has a negative impact on airports’ efficiency in Italy from 2005 to 2008. This implies that airports belonging to a local air transportation system where competition is strong exploit their inputs less intensively than do airports with local monopoly power. Further, we find that public airports are more efficient than private and mixed ones. Hence, policy makers should provide incentives to implement airports’ specialization in local systems where competition is strong and monitor the inputs’ utilization rate even when private investors are involved.
► We apply a stochastic distance function model with time-dependent efficiency scores. ► We compute airports’ markets on the basis of a potential demand approach. ► The intensity of competition has a negative impact on Italian airports’ efficiency. ► Public airports appear to be more efficient than private and mixed ones.
