Item Open Access Airport ground access and private car use: a segmentation analysis(Elsevier, 2014-04-30) Budd, Thomas; Ryley, Tim; Ison, StephenThe increasing scale of, and demand for, civil air transport world-wide has resulted in a greater volume of people travelling to and from airports. The vast majority of these journeys are made by private cars, which has led to traffic congestion and raised levels of air pollution in and around airports. Subsequently, airports are re-evaluating their approach to ground access mode choice and considering how to reduce the reliance on private cars. Based on a survey of passengers at Manchester Airport in the UK, attitude statements pertaining to psychological constructs from the Theory of Planned Behaviour and the Norm-Activation Theory, combined with key factors relating to the passenger’s trip, are used to identify eight behaviourally distinct groups of passengers with varying potential to reduce their private car use. Two of these groups, described as the Conflicted Greens and the Pessimistic Lift Seekers, are identified as having the greatest potential to reduce private car use to airports. Analysis reveals the need for decision makers to address the existing attitude–behaviour ‘gap’ that can prevent positive environmental attitudes being translated into the use of more sustainable modes, as well as tackling the perceived difficulty some passengers associate with using these modes.Item Open Access Airport surface access in the UK: A management perspective(Elsevier, 2011-05-24) Budd, Thomas; Ison, Stephen; Ryley, TimAir passenger traffic in the UK has increased significantly over the last 30 years, and is forecast to continue to grow for the foreseeable future. A key associated challenge for airports involves the management of airport surface access. Currently, airport surface access in the UK is heavily reliant on trips by private car, which has resulted in congestion on local road networks and raised levels of pollution from vehicle emissions. The paper offers an airport management perspective on airport surface access in the UK. Semi-structured interviews with key personnel responsible for surface access management at 14 UK airports revealed a wide variety of surface access issues and management policies. The need to reduce the share of journeys made by private car is identified as a key issue, with a particular focus on reducing ‘kiss-and-fly’ journeys for passengers. Whilst reducing private car journeys may yield environmental benefits, such strategies are largely at odds with substantial commercial pressures to maximise the revenue potential of airport parking.Item Open Access Assessing the fuel burn and CO2 impacts of the introduction of next generation aircraft: A study of a major European low-cost carrier(Elsevier, 2016-09-17) Budd, Thomas; Suau-Sanchez, Perehe introduction of more fuel-efficient ‘next generation’ aircraft has the potential to yield benefits for fuel burn and CO2 emissions over current generation aircraft. This has important implications in terms of airline fuel costs and competition, but also for compliance with future environmental legislation and market based incentive schemes. In Europe, major low-cost carriers such Ryanair, easyJet, and Norwegian Air Shuttle have been active in updating their fleet, and they now operate some of the youngest fleets in the industry. Subsequently, the paper assesses the possible fuel burn and CO2 impacts of the introduction of next generation aircraft by employing OAG data and EUROCONTROL's ‘Small Emitters Tool’ to determine the annual fuel burn and CO2 emissions for easyJet, a major European low-cost carrier. Estimations were then made regarding the potential impacts on fuel burn and CO2 emissions from the introduction of the airline's next generation of aircraft under three fleet plan scenarios. Analysis indicates that while new aircraft may allow airlines to increase the capacity in their network with only a marginal increase in overall fuel burn and CO2 emissions, this is unlikely to lead to substantial overall reductions in total fuel burn and emissions, at least in the short term.Item Open Access An assessment of air passenger confidence a year into the COVID-19 crisis: A segmentation analysis of passengers in Norway(Elsevier, 2021-09-28) Budd, Thomas; Suau-Sanchez, Pere; Halpern, Nigel; Mwesiumo, Deodat; Bråthen, SveinThe COVID-19 crisis has become the most intense and long-lasting in the history of aviation. There is already a significant literature on the immediate impact of the outbreak, as well as on speculation on the future evolution of the industry. This paper seeks to contribute to this discussion by assessing a year into the crisis the demand related aspects and passenger behavioural impacts of the pandemic. Specifically, the paper aims to identify discrete market segments of air passengers according to their shared attitudes and preferences about air travel in light of the COVID-19 crisis, as well as past behaviour and future travel intentions. To achieve this, we analyse data from a large (n = 2096) online questionnaire survey of air passengers in Norway. The cluster analysis identifies four distinct passenger segments, with each displaying varying attitudes, behaviours, and levels of concern about air travel. One of these groups, described as the ‘Apprehensive Elders’, were identified as having the highest level of concern about flying, and subsequently showed a sharp decline in their intention to travel in the future. Another group, termed the ‘Cautious Commuters’, showed similarly enhanced levels of concerns about flying, but maintained a high propensity to fly following the pandemic despite these concerns. Regarding possible interventions to increase confidence in flying in the future, across all segments the data shows a clear preference for more ‘traditional’ active interventions, including wearing of face masks and enforcement of physical distancing, over and above passive or technological interventions. Norway represents a valuable case as a possible signal for future policy and practice in relation to the recovery of air travel following the pandemic. The findings have important implications for air transport managers and decision makers in terms of managing the perceptions and expectations of different passenger groups as air travel begins to return.Item Open Access Conceptualising airport digital maturity and dimensions of technological and organisational transformation(Henry Stewart Publications, 2021-03-01) Halpern, Nigel; Budd, Thomas; Suau-Sanchez, Pere; Bråthen, Svein; Mwesiumo, DeodatAs airports undergo digital transformation, ie a paradigmatic shift in the way digital technologies are adopted and used, there is a need for actionable insights to ensure that airport digital maturity is achieved. Using an integrative review of literature, this paper develops an airport digital maturity model, focusing mainly on a passenger experience perspective. The paper then delineates two dimensions of digital transformation — technological and organisational. Subsequently, an airport digital transformation model is conceptualised to identify key factors that airports need to consider when transforming their business and interesting lines of enquiry for future research. Insights offered by the model are relevant to both practitioners and researchers interested in conducting future studies in this area.Item Open Access Environmentally sustainable practices at UK airports(ICE Publishing, 2015-04) Budd, Thomas; Budd, Lucy; Ison, StephenIn response to growing concerns about rising energy bills, long-term energy security and the environmental impacts of greenhouse gas emissions, airport operators worldwide are increasingly implementing new sustainable practices to help reduce costs, increase efficiency and reduce their environmental impacts. These initiatives include the installation of on-site wind turbines, biomass plants, and ‘smart' heating and lighting systems as well as other ‘green' initiatives including rainwater harvesting initiatives, improved recycling facilities and financial incentives to encourage staff to travel to work by modes other than the private car. Drawing on specific examples, this paper examines the ways in which UK airports have responded to the challenge of reducing the environmental impacts of operations for which they are directly responsible by implementing green and sustainable energy and working practices. The paper concludes by discussing the importance of sustainable airport practices in light of future growth in key emerging aviation markets.Item Open Access An exploratory and confirmatory composite analysis of a scale for measuring privacy concerns(Elsevier, 2021-07-23) Mwesiumo, Deodat; Halpern, Nigel; Budd, Thomas; Suau-Sanchez, Pere; Bråthen, SveinThis paper reports a confirmatory composite analysis of a scale for measuring privacy concerns, and the effect of privacy concerns on the willingness to provide personal data. The analysis is based on 468 survey responses, divided into two contexts: airport digital services and online retail services. Results from both contexts confirm that privacy concerns consist of a third-order construct comprising two-second order constructs (interaction management and information management) and a first-order construct (awareness). The effect of privacy concerns on the willingness to provide personal data is higher in the airport digital context than in the online retail context. Also, the relevance of the three dimensions varies by context. Thus, researchers must carefully consider their research context and include items for the most relevant dimensions of privacy concerns in measurement models. Likewise, managers must prioritise dimensions of privacy concerns according to their business context.Item Open Access Exploring the expectations of transport professionals concerning the future automobility system: visions, challenges, and transitions(Taylor and Francis, 2017-04-05) Morton, Craig; Budd, Thomas; Harrison, Gillian; Mattioli, GiulioA mixture of potentially significant changes in technology, commercial structures, and social practices is currently entering the automobility system. These changes have the potential to combine together and lead to a substantial shift in the manner in which society fuels, owns, and makes use of its cars. This paper reports a research project that made use of focus groups to examine the narratives of British transport professionals concerning forthcoming developments in the automobility system. Specific attention was given to what the expectations for future change in automobility are, if these changes will likely lead to a transition toward a more sustainable system and the manner in which a transition of this nature could be facilitated. The oral testimony offered during the focus groups has been assessed qualitatively using thematic analysis. The results suggest that there is a commonly held view that the automobility system is entering a stage of flux, which may lead to considerable changes in system configuration. However, the attainment of a sustainable transition for the system will likely be inhibited by a series of institutional, societal, and physical barriers, which may restrict system developments.Item Open Access The impact of climate hazards to airport systems: a synthesis of the implications and risk mitigation trends(Taylor and Francis, 2023-01-06) Voskaki, Asimina; Budd, Thomas; Mason, KeithClimate hazards have only fairly recently been acknowledged as key risk factors for airports. While there is a growing body of research examining specific climate change impacts, there is only limited work that combines this literature with overall climate risk. This paper seeks to address this gap in the literature by investigating and synthesising findings from studies relating to historical airport sensitivity to climate hazards and offering insights on the overall climate risk for the global airport system. With airports increasingly needing to become more “climate-resilient” due to projected changes in global climate, airport planners and decision-makers face challenges in terms of identifying key priority areas for resilience planning and investment. The findings of the paper provide insights into these challenges by examining best-applied practices and current levels of vulnerability. The paper supports the wider inclusion of climate risks as a key factor in airports’ planning and operational processes. This will require transforming current management cultures to enhance an airport's operational ability to respond to climate events efficiently and recover quickly in the event of a disruption.Item Open Access Improving the environmental performance of airport surface access in the UK: The role of public transport(Elsevier, 2016-10-11) Budd, Lucy; Ison, Stephen; Budd, ThomasSimultaneously increasing the proportion of airport surface access journeys that are made by public transport modes and reducing the environmental effects of airport access/egress trips while accommodating growing consumer demand for air and surface access travel are priority areas for the air transport industry and the UK Government. Given the urgent need to reconcile commitments to environmental sustainability with commercial and economic imperatives for growth, this paper analyses the surface access strategies of London's six busiest passenger airports to identify the current challenges of airport surface access provision, examine opportunities for improvement within existing and future infrastructure and offer recommendations as to how increased public transport provision and patronage could improve the environmental performance of UK airport surface access.Item Open Access Modelling the effect of electric aircraft on airport operations and infrastructure(Elsevier, 2022-02-09) Doctor, Faiyaz; Budd, Thomas; Williams, Paul D.; Prescott, Matt; Iqbal, RahatElectric aircraft offer the potential for emissions savings towards decarbonising air transport and reducing its contribution to climate change. However, the characteristics of these novel technologies pose questions about how they can be integrated with existing airport infrastructure. Key considerations relate to the time needed to recharge electric aircraft whilst on the ground without adversely affecting operational capacities, and the requirement for airport operators to install electric charging capabilities. The paper applies queuing theory and simulation modelling techniques to help identify potential battery charging regimes for electric aircraft based on potential forecasts of the future electric aircraft fleet. An initial prototype discrete event simulation model was developed to simulate impacts of short-haul electric aircraft on airport capacity to help determine future infrastructural requirements. Computational optimisation techniques were used to determine optimal configurations of single purpose and converted dual purpose aircraft parking stands under different scenarios and charging regimes. The model demonstrated that a future increase in electric aircraft equating to 25% of the global aircraft fleet required the conversion of only 13% of existing parking stands, while maintaining airside capacity and operational efficiency. The findings have important implications for air transport planners and decision makers in the transition to zero emissions and flight.Item Open Access Passenger choices and preferences for aircraft cabins in a culture-specific case: Japan.(Cranfield University, 2019-10) Uyan, Berkcan; Budd, Thomas; Miyoshi, Chikage; Pagliari, RomanoThis thesis aims to identify the key aspects in the cabin interior and services by focusing on passengers’ preferences and to estimate the willingness to pay for different services and attributes in a culture-specific setting. The scope of the study includes passengers in Japan across all airline business segments for short-haul and medium-haul flights, utilising 2,700 stated preference observations included within a passenger survey conducted in Japan in 2016. While the identification of culture-specific characteristics and trends in Japan are analysed with a qualitative study, choice models and willingness to pay estimates for cabin features and services are revealed with a quantitative study. A stated preference (SP) survey is designed for choice models developed with multinomial and mixed logit models to analyse the results. The study includes two main categories in cabin; cabin interior and cabin services. Key aspects in the cabin interior included in the study are the physical attributes of the cabin in terms of space and seats. For in-cabin services, different levels of technologies including inflight entertainment (IFE), internet connection, and power supply and meal service are considered. A significant difference between medium (3-6 hours) and short- haul (<3 hours) flights is found based on entertainment and seating space along with expected meal services provided (i.e. the willingness to pay for seat pitch is $2.82 for short-haul while it is $12.76 for medium-haul flights). While the overall expectations for in-cabin services are not relatively high in short-haul flights, the results indicate towards high expectations for some attributes in medium-haul flights. These outcomes along with the understanding of Japanese passengers can contribute to the knowledge for an optimal ancillary revenue system, and the cabin interior and configurations in a culture-specific setting. Eventually, they may act as important parameters for the aircraft investment appraisal as a result in a specific region. Through the analysis, the value of seat pitch along with internet connection which can be interpreted as a form of IFE are found to be significant for passengers in Japan. In addition, the difference in the preferences of passengers for short and medium-haul flights are revealed and forecasted for different flight durations to give an insight into the valuation of cabin attributes for longer flights. The results indicate valuable outcomes to be considered based on culture-specific preferences for cabin design and services.Item Open Access Perceived benefits as a driver and necessary condition for the willingness of air passengers to provide personal data for non-mandatory digital services at airports(Elsevier, 2023-03-28) Mwesiumo, Deodat; Halpern, Nigel; Bråthen, Svein; Budd, Thomas; Suau-Sanchez, PereThe willingness of individuals to provide personal data is of interest to policymakers and practitioners seeking to develop more intelligent transportation systems that create value for passengers using technologies, as well as to leverage the use of data more generally to accelerate digital transformation. This study examines the role of perceived benefits as a driver and necessary condition for the willingness of air passengers to provide personal data for non-mandatory digital services at airports. These are services that are not essential for the operation of the airport or for the safety and security of passengers but can enhance the passenger experience or generate additional revenue for the airport. Examples include receiving notifications to a mobile device about their journey and related products and services, accessing customer services online, joining and receiving electronic information from an airport loyalty programme, and making payments for products and services online or via a mobile application. The analysis is based on two samples of 235 and 218 respondents to an online survey where the second sample is used for the purpose of replication. Responses were analysed using a recently developed complementary approach that combines partial least squares structural equation modeling and necessary condition analysis. The findings confirm that perceived benefits are a significant driver and necessary condition for passengers’ willingness to provide personal data. More so, perceived benefits significantly attenuate the negative effect that privacy concerns have on passengers’ willingness to provide personal data. The findings offer theoretical and methodological contributions, as well as implications for policy and practice.Item Open Access Ready for digital transformation? The effect of organisational readiness, innovation, airport size and ownership on digital change at airports(Elsevier, 2020-10-06) Halpern, Nigel; Mwesiumo, Deodat; Suau-Sanchez, Pere; Budd, Thomas; Bråthen, SveinThis study investigates the effect of organisational readiness, innovation and airport size and ownership on digital change at airports. Data is collected from a survey of managers at 94 airports worldwide and analysed using partial least squares structural equation modelling. Organisational readiness is found to have a direct effect on digital change. Organisational readiness also has a direct effect on innovation, which subsequently affects digital change. Airport size has a direct effect on digital change while the effect of ownership is not significant. The findings show that successful development of organisational readiness can be used to speed up the rate of innovation needed for digital change at airports.Item Open Access Segmentation of passenger preferences for using digital technologies at airports in Norway(Elsevier, 2021-01-07) Halpern, Nigel; Mwesiumo, Deodat; Budd, Thomas; Suau-Sanchez, Pere; Bråthen, SveinAirports are increasingly focused on implementing digital technologies at key stages of the airport journey to enhance the passenger experience. However, passengers have different preferences. TwoStep Cluster Analysis is used to reveal the presence of distinct segments according to their preferences. The findings are based on a survey of 6082 passengers at airports in Norway. Three distinct segments are identified: those that prefer traditional manual processes, those that prefer automated technology-based processes, and those that prefer more personalised technology-based processes. Significant differences are revealed for each segment according to passenger and trip characteristics and opinions regarding how the use of digital technologies at airports impact on personal privacy and human dignity. The findings contribute to knowledge on passenger preferences at airports and can help to inform airport decision makingItem Open Access Tweeting Transit: An examination of social media strategies for transport information management during a large event(Elsevier, 2017-02-21) Cottrill, Caitlin; Gault, Paul; Yeboah, Godwin; Nelson, John D.; Anable, Jillian; Budd, ThomasSocial media platforms are seeing increasing adoption by public transport agencies, as they provide a cost-effective, reliable, and timely mechanism for sharing information with passengers and other travellers. In this paper, we use a case study of the @GamesTravel2014 Twitter account to evaluate how this social media platform was used over the course of the 2014 Commonwealth Games in Glasgow, Scotland to provide and share transport-related information and respond to information requests. The case study provides an exemplar for the public co-ordination of information from multiple partners in a complex environment during a time of transport disruption. We evaluate both the structure and intent of the @GamesTravel2014 social media strategy via interviews with involved parties and an analysis of Tweets related to the account. Findings indicate the potential for future applications of social media by transport operators and authorities in producing a more effective network of communication with passengers.
