Do the regional growth effects of air transport differ among airports?

This paper empirically studies the contribution of air transport to regional economic development in Germany. We find that the scale and direction of output effects of air services and airport infrastructure differ among airports. These differences are driven by ‘opportunity costs’ of airport capital and by positive output effects from air transport connectivity. We argue that the latter impacts potentially depend on traffic characteristics.     

Perspectives and images of cycling as a barrier or facilitator of cycling

The public images of cycling can act as barriers or facilitators of cycling. This qualitative study explored images and perceptions of cycling, their potential influence on cycling and whether these views differed between regular, occasional and non-riders.Seventy participants (24 males and 46 females) were recruited. Of these, 22 were classified as non-riders, 23 were occasional riders and 25 were regular riders. Twelve focus groups were held in inner Sydney during October and November 2005. Data were audio taped, transcribed and thematically analysed.Themes linked to images of cycling included: ‘clean and green’; ‘healthy and fun’; ‘dangerous’ and ‘serious business’. Themes linked to images of cyclists included: ‘risk takers and law breakers’ and ‘status and sub-cultures’. Discussion centred on the low social status of riding over other transport modes, the relative acceptability of different riding sub-cultures, the ‘green’ image of cycling transport and the status associated with the riders clothing and bicycle choice, especially lycra and its ‘serious and sporty’ connotation.While ‘cycling’ was generally viewed as a positive, environmentally friendly activity, the actions of some ‘cyclists’ were disliked, which influenced views about cycling, particularly among non-riders. A cycling acceptability hierarchy emerged; with recreational riding at the top, followed by cycling for sport and exercise, with transport/commuter cycling towards the bottom. Bicycle couriers were viewed least favourably. A common perception among non-riders was the latter two groups were rule breakers and risk takers, while regular riders felt unfairly judged by this stereotype.While there was greater acceptance of recreational riding, riding for transport was not viewed as a mainstream activity. There is a need to improve the public acceptability of cycling and change public norms so it is seen as an everyday activity that can be undertaken by almost anyone, without the need for special clothing, expensive equipment or limited to purpose built facilities.     

Housing mobility and travel behaviour: A process-oriented approach to spatial mobility: Evidence from a new research field in Germany

During recent years, some effort has been made to understand the location changes in the life course underlying travel demand in Germany. Such studies have presented travel behaviour and long-term housing mobility as intertwined decision flows within the life course. This perspective calls for new methods, for example comparisons of travel behaviour before and after relocation, or comparisons between different ‘relocation types’. A number of studies have taken on this new perspective. Although there are certain methodological problems arising, notable progress has already been achieved towards a more precise understanding of travel demand. This includes the investigation of the use of transport modes as well as travelled distances and activity spaces. This contribution provides an overview on these studies. Theoretical groundwork, empirically validated aspects, and deficits and blind spots of research are being discussed.     

Funding for local authority transport and land-use schemes in the UK

This paper focuses on the research activities, findings and planned products of one of the UK EPSRC-funded DISTILLATE (Design and Implementation Support Tools for Integrated Local Land use, Transport and the Environment) projects on the funding of transport and land-use schemes. Research activities have included a literature review, dialogue with local authority case studies and a funding workshop. The research identified and explored a range of barriers to funding, including lack of revenue funding, difficulties in obtaining funding for ‘soft’ schemes, the formation of partnerships and timing-related issues. The research also revealed that the funding system is failing to meet the needs of the current transport policy focus on managing travel demand, rather than being a supply-led process. The key project outputs are described, which include a ‘funding toolkit’ for local authorities, and guidance for funding bodies regarding the barriers faced.     

Constraints affecting mode choices by morning car commuters

In New Zealand as elsewhere, there is an increasing interest in alleviating congestion on the road transport network to improve economic productivity, reduce pollution, and to use the transport network more effectively. Governments enact various policies to encourage car drivers to change their behaviour, but often find that the full impact is not reached. We propose that car drivers have constraints influencing their mode choice for the morning peak period trip (e.g. needing to transport children, needing a car for work during the day). A stated preference experiment conducted in the three largest New Zealand urban areas not only quantifies the likely impact of a wide range of policy tools (both ‘sticks’ discouraging car use, and ‘carrots’ encouraging alternative modes) for each area, but also identifies many significant constraints.     

The development of an option generation tool to identify potential transport policy packages

While techniques for identifying urban transport problems, predicting the effects of possible solutions and appraising their performance are well developed, there is a significant gap in the decision-making chain relating to the generation of those possible solutions. A literature review has identified a number of option generation methods in other sectors, which are of potential application to transport. It categorises them into ‘inside the box’ methods, which are principally quantitative and draw on a pre-existing list of solutions, and ‘outside the box’ methods, which are more qualitative but potentially better able to generate wholly novel solutions. It also distinguishes between applications at the levels of formulation of an overall strategy and of detailed design of a particular scheme. An ‘inside the box’ method for strategy option generation has been developed building on the capabilities of an existing web-based knowledgebase, KonSULT. The design principles are described and potential further developments outlined.     

Urban transport justice

Many cities in the world seek to establish more sustainable urban transport systems with a view to reduce accidents, congestion, air and noise pollution, and to improve social interactions, liveability and amenity values. Against this background, this paper frames urban transportation as an issue of justice: contemporary transport systems are characterized by injustice, as they tend to favour and prioritize motorized transport, accepting that considerable environmental and social burdens are put on more sustainable forms of transportation, other traffic participants and society as a whole. To conceptualize ‘urban transport justice’, the paper discusses three dimensions where injustices are apparent: Exposure to traffic risks and pollutants; distribution of space; and valuation of transport time. It is argued that public and political recognition of urban transport injustices provides significant argument for changes in urban planning, transport infrastructure development and traffic management.     

Exploring public transport as an element of older persons' mobility: A Capability Approach perspective

This study employs Amartya Sen's Capability Approach as a guiding conceptual framework in the exploration of public transport as an element of mobility among the young-old living in Stockholm, Sweden. The aim is to shed light on the variation in mobility resources of those who perceive they can use public transport as their primary mode of transport and of those who perceive they cannot (‘mobility capability element’), as well as that of those using public transport and of those not using it (‘mobility functioning element’). Increasing residential density, being female and having a higher functional capacity were among the mobility resources which produced a positive increase in the likelihood of considering it possible to use, and the use of, public transport. The higher the ratio of cars to household member, the lower the likelihood of including public transport as a mobility capability element or as a mobility functioning element. Most of those who included public transport use as both a mobility capability element and a mobility functioning element were also users of the private car. There was also a tendency towards car use rather than towards no travel if the individual was not a user of public transport. Through the application of the Capability Approach, this paper facilitates further insight into the variation in mobility resources, corresponding mobility capability and mobility functioning elements of this group, with respect to public transport. It also opens up questions for the future employment of this conceptual framework within transport research.     

From Mobike to no bike in Greater Manchester: Using the capabilities approach to explore Europe's first wave of dockless bike share

Globally, bike share schemes are an element of a rapidly changing urban transport landscape. Whilst many docked schemes are now embedded in cities around the world, the recent explosion of dockless systems provides an opportunity to evaluate claims that this form of shared mobility has the potential to alleviate common barriers to cycling, relieve congestion, boost low carbon travel, get people active, and reduce social exclusion. Drawing on a mixed methods study of 2270 online survey respondents and 27 interviews, all living in, working in or visiting Greater Manchester during a trial of dockless bike share, we explore the ways in which the technological, spatial and practical configuration of bike share schemes relate to a city's infrastructure and existing cycling practices. We question assertions that bike share provision necessarily results in increased rates of cycling and enhanced social inclusion.By using a capabilities approach and utlilising the concept of ‘conversion factors’ to describe the differing capacities or opportunities that people have to convert resources at their disposal into ‘capabilities’ or ‘functionings’, we show how the practice of bike sharing can influence a population's propensity to cycle, as well as how bike share interacts with established barriers to cycling. We find that many established barriers to cycling remain relevant, especially environmental factors, and that bike share creates its own additional challenges.We conclude that bike share operators must recognise the role of personal and social conversion factors more explicitly and be sensitive to the social and physical geography of cities, rather than assuming that a ‘one size fits all’ approach is adequate. To do this they should engage more closely with existing bodies, including transport authorities and local authorities, in co-creating bike share systems. Using the capabilities approach enables us to identify ways in which it could be made relevant and accessible to a more diverse population.     

Inside the black box: EU policy officers' perspectives on transport and climate change mitigation

Transport is a significant and growing contributor to climate change. To stay within ‘safe’ global warming guardrails requires substantial cuts in greenhouse gas emissions. This represents a global political consensus, but there is evidence that current legislation in the transport sector is not significant enough to achieve medium- and longer-term reduction goals. In focusing on the European Union, this paper investigates the perspectives of twelve policy officers in three Directorates-General (MOVE, CLIMA, ENV) of the European Commission with regard to their understanding of mitigation goals and timelines, responsibilities for policy development and implementation, and perceived efficiencies of these policies to achieve climate objectives in the transport sector. Results indicate diverging and common views on climate policy goals and political responsibilities, as well as barriers to policy-making, including lack of political leadership on climate change mitigation, resistance from member states, the favoring of economic growth over cuts in greenhouse gas emissions, pressure from industry and lobby groups, preferential treatment of aero- and automobility over more sustainable transport modes, policy implementation delays, insufficient forecasting and monitoring tools, and an overreliance on technologies to contribute to emission reductions. In offering a view inside the ‘black box’ of transport policy-making, the paper reveals fundamental institutional (structural) and individual (agency-based) barriers that will have to be overcome if significant emission cuts in the transport sector are to be achieved.     

Crowding and public transport: A review of willingness to pay evidence and its relevance in project appraisal

This paper reviews public transport crowding valuation research, using a number of primary studies conducted in the UK, USA, Australia and Israel. We identify three measures used to value crowding (a time multiplier, a monetary value per time unit and a monetary value per trip), and associated ways of representing crowding in stated preference experiments. Although a number of different types of crowding in terms of location are identified, namely in-vehicle, access-way, entrance and platform/station, the majority of reviewed studies investigate only in-vehicle crowding. Despite the different characteristics of the reviewed studies, they all report that crowding would increase the value of travel time savings, which can be viewed as an additional component of generalised time. This paper also comments on the role that the WTP for crowding reduction can play in project appraisal, and suggests some important avenues for future public transport crowding valuation research.     

Managing public transport in developing countries: Stakeholder perspectives in Dar es Salaam and Faisalabad

Most developing country governments face the dilemma of how to promote affordable public transport for the urban poor. In developing countries, the trend of turning to the private sector for the provision of public transport services has resulted in a large number of individual operators whose main aim is (not surprisingly) to maximise profits. The drive for profitability can be achieved by increasing efficiency and cutting bloated costs, but may also lead to unfavourable behaviour that can adversely affect passenger safety and comfort and could also damage the urban environment. The challenge is to find a way to regulate and control this multiplicity of small businesses in such a way as to retain the cost minimisation pressures of the profit-seeking private sector without sacrificing safety, health or quality of service.This paper presents a comparison of stakeholder attitudes to the regulation and control public transport in Dar es Salaam (Tanzania) and Faisalabad (Pakistan). The views of stakeholders were established as part of a wider DFID-sponsored study of ‘Partnerships to improve access and quality of urban public transport for the urban poor’ and were collected using content analysis, literature reviews, historical analysis, case studies, focus group discussions, forums and workshops. The stakeholders involved included users, particularly passengers from low-income households, providers and operators of services (drivers and conductors), and regulatory agencies. The example of the Faisalabad Urban Transport Society (FUTS), effectively a public–private partnership, is described to provide a useful model of regulation and control of private sector operators as well as for reconciling the interests of multiple stakeholders.     

Environmental costs in European aviation

This paper presents estimates of environmental costs in a set of 36 European airline markets. Cost are calculated for noise, air pollution and accident risk using data on aircraft emissions, exposure-response parameters and economic valuation of environmental goods. The ‘medium value’ cost estimate is 0.0201ECU per passenger-km. This result suggests that environmental costs represent only a small fraction (2.5%) of the internal cost of aviation as measured by the average ticket price. Noise costs are the dominant environmental cost at some 75% of the cost total. The medium estimates are sensitive to changes in the various assumptions in the pathways: a low and high estimate are three times lower and five times higher, respectively, than the medium estimate. The study further suggests that there are environmental economies of scale in air transport and that Chapter 2 aircraft are about a factor four more environmentally costly than Chapter 3 aircraft.     

Transport and climate change: Simulating the options for carbon reduction in London

Transport is a major user of carbon-based fuels, and it is increasingly being highlighted as the sector which contributes least to CO₂ emission reduction targets. This paper reports on the findings of the VIBAT London study (www.vibat.org) which considers the role of the transport sector in reducing CO₂ emissions in London.The analysis develops a transport and carbon simulation model (TC-SIM) for London. Within this, users are able to consider the implementation of a series of potential policy packages—low emission vehicles, alternative fuels, pricing regimes, public transport, walking and cycling, strategic and local urban planning, information and communication technologies, smarter choices, ecological driving and slower speeds, long distance travel substitution, freight transport and international air. They can select variable levels of application to help achieve headline CO₂ emission reduction targets. The roles of carbon rationing and oil prices are also considered. TC-SIM can be played in different user modes: as ‘free riders’, ‘techno-optimists’, ‘enviro-optimists’, ‘complacent car addicts’ and other typical travel market segments, including a ‘free role’. Game playing or scenario testing such as this helps to highlight perceived levels of homogeneity of views within certain cohorts, the development of entrenched positions and the likely success in achieving objectives.The paper develops various policy packages, scenarios and pathways aimed at reducing transport CO₂ emissions. It argues that strategic CO₂ emission reduction targets are very ambitious relative to current progress, and that we need to act more effectively across a wide range of policy mechanisms, with a ‘high intensity application’ of many of the options, to get near to achieving these targets. A critical issue here will be in communicating and gaining greater ‘ownership’ of future lifestyle choices with stakeholders and the public, and participation tools such as TC-SIM could become increasingly important in this area.     

Understanding accessibility through public transport users' experiences: A mixed methods approach

The quantitative measurement of accessibility through public transport has become more complex and accurate over time. However, it lacks many of the deeper nuances of how people actually experience their travel environments. Our previous works have highlighted the importance of incorporating the lived travel experiences of passengers within accessibility indicators, considering the quality of the walking environment and different attributes of the public transport services.Building on these works, this mixed-method research seeks to further improve the characterization of accessibility according to users' travel experiences, as described by those attributes that inhibit or enhance access to opportunities within the city. We use content analysis of focus groups, data gathered in a brief survey and sociodemographic and public transport data for our analyses. Our main contributions are (i) to develop a conceptual framework to analyze qualitative data on how people relate and discuss their public transport accessibility experiences and (ii) to develop accessibility indicators differentiating user perceptions. We apply this novel conceptual framework and methods to the unique urban morphology of two municipalities of Santiago de Chile.We identified different ‘socially constructed’ narratives for buses and metro. The participants focused on barriers to accessibility, showing an important relationship between them, as well as substantial differences in their overarching positive perception of metro and negative for buses. However, when disaggregating the analysis by primary transport mode and location, we found ‘hidden’ values for buses, recognizing its capillarity and underlying connectivity with the metro system. Furthermore, we found a dissimilar perception of transport environments when disaggregating the analysis by gender, age and location, which translated into different accessibility profiles for the various public transport users. From these experiential qualitative perspectives, it was thus possible to determine some attributes that had been previously overlooked in more quantitative studies but which are important when analyzing public transport accessibility for different population groups.     

Cycling in multimodal transport behaviours: Exploring modality styles in the Danish population

Multimodality is important for achieving less car dependent lifestyles and more sustainable transport behaviours. It is widely recognised that cycling plays a prominent role in sustainable transport. However, research has largely focused on cycling substituting motorised transport. This study explores how cycling forms part of multimodal transport behaviour based on survey data on transport modes and travel purposes and the weekly frequency of out-of-home activities and travel mode use in a representative sample of adult Danes (n = 1957). The following five distinct multimodal travel segments or ‘modality styles’ are identified: ‘education transport’; ‘public-based transport’; ‘limited transport’; ‘bicycle-based transport’; and ‘car-based transport’. Travel behaviour is predominantly multimodal with few unimodal car-drivers being identified. Substantial cycling takes place in all modality styles, and is embedded in a multimodal behaviour as the modality style combined cycling with several other modes. Furthermore, the study demonstrates that cycling serves many purposes that transgress the division of utility cycling and recreational cycling, and that cycling takes place in both dense urban settings and small towns. Thus, the way in which travel modes relate to the urban environment and variations in modality styles must serve as the starting point for policies aiming to fulfil the potential of multimodal transport behaviour and promote cycling.     

Informal,essential and embedded: Transport strategies in remote Sarawak

Transport is a main concern for people living in rural and remote communities around the world, where the absence of affordable and reliable transport often prevents access to education, health services and employment opportunities. In Sarawak, a state of Malaysia on the island of Borneo, many rural villages experience acute transport poverty. For their basic transport needs, people here rely on informal transport systems based on local social and cultural networks, which provide essential mobility.We apply Polanyi's concept of social embeddedness to explore mobility in this region, people's efforts to develop regional models of entrepreneurship but also the relative marginalisation of remote communities in terms of development and infrastructure provision and the resulting friction between local people, the companies involved in regional resource extraction activities and local government. Based on data collected between 2015 and 2017, we frame informal transport in this region as a form of Indigenous entrepreneurship that can help local communities achieve wider social and economic inclusion. Our research points to a more social type of entrepreneurship and economic practice, in which social relationships and community responsibilities play an important role. Our qualitative approach, including ethnographic methods such as semi-structured interviews and participant observation, underpins the groundedness of our data in the every-day experiences of the people who took part in the research.     

Transport project appraisal in the European Union

This paper reviews transport appraisal methods in use in the countries of the European Union. A key element of the paper is an examination of the range of costs and benefits included in appraisal and the degree of consensus on their measurement and valuation. There is a strong consensus on the treatment of a number of direct impacts, where monetary valuation and inclusion in cost benefit analysis is usual. There is less agreement on the treatment of the environmental and social impacts. Recent developments are in the direction of comprehensive multi-modal approaches and a greater use of multi-criteria analysis.     

Valuation effects of mergers and acquisitions in freight transportation

This study investigates valuation effects of mergers and acquisitions in the freight transportation industry. It is found that mergers and acquisitions create synergistic gains, especially tender offers, consistent with the view that freight transportation mergers and acquisitions occur for synergistic reasons rather than management’s desire for empire building or perk consumption. Both target’s and bidder’s shareholders are better-off, but most of the synergistic gains accrue to the target’s shareholders. Targets’ valuation effects are greater for vertical rather than horizontal mergers, indicating a positive valuation for firms that control and manage a more extensive supply chain. The bidders’ wealth effects are greater for friendly mergers. Overall, the findings have important implications for professional practice and the development of the theoretical literature.
