Equity has been a major concern of public transport provision and is required by legislation in many countries. Several approaches measure equity in transit supply however none produce a simple system-wide measure of equity performance. A new approach is presented using Lorenz curves to measure the relative supply of transit to the population. Gini coefficients provide a single measure of overall equity using this method. A system-wide assessment of overall transit supply to the population in Melbourne, Australia shows that 70% of the population shares only 19% of the supply (Gini coefficient = .68). When employment is also taken into account, the situation is not much different; 70% of jobs and population share 23% of service (G = .62). In order to gain some understanding of vertical equity, the transit supply was compared between different age, income and vehicle ownership groups. There is some evidence of higher supply for youth and low-income groups in inner Melbourne, and in all parts of Melbourne no-vehicle households lived in areas of higher transit supply. Overall it is unclear how “fair” these distributions are compared to equity in other cities since this is the first time this method has been undertaken. Projects using similar approaches should provide a good basis for establishing comparative equity between cities.  相似文献

This paper examines the student experience of transport, within the context of two hitherto distinct discourses. Firstly, the transport and social exclusion discourse, which highlights the role that low mobility plays in the experience of exclusion. Secondly, the widening participation discourse, which emphasises inequitable access to and achievement in higher education (HE) by non-traditional students as a component of social exclusion. The paper reports the results of a series of focus groups, undertaken with current HE students from a diverse range of backgrounds, many of whom may be considered to be non-traditional students. Results suggest that inadequate access to transport is a substantial barrier to access and achievement in HE, for these students. This highlights the influence of transport upon the successful implementation of social policy. Without consideration of transport and the physical accessibility of HE, the aim of increasing and widening participation in HE is unlikely to be realised.  相似文献

This paper addresses the issue of ownership structure and corporate performance. It employs a sample of 107 internationally listed shipping firms (about 60% of the total) and examines their financial data and ownership concentration for the year 2009. Ownership is treated as an endogenous variable and GMM estimation is used incorporating the significant advance provided by Lewbel (1997). Empirical results suggest that concentrated ownership is positively and strongly associated with better firm performance in the shipping industry. Furthermore, this paper offers evidence on ownership concentration and shows that despite the different corporate governance settings, ownership structures are quite similar in shipping.  相似文献

Transport biofuels in the European Union: The state of play   总被引:2,自引:0,他引:2  
The implementation of the Biofuels Directive (2003/30/EC) in 25 member states is assessed here. Implementation problems are identified and analysed for the purpose of suggesting a way forward for biofuels policy in the European Union. Three main patterns are observed: effective implementation, formal compliance and weak implementation. Problems encountered in the policy process are both of a practical and more fundamental nature, i.e., due to a lack of consensus on the priority of competing policy objectives and disagreement on the suitability of first-generation biofuels for reaching the objectives. In this situation, stronger enforcement of targets does not appear to be a constructive way forward. Based on our analysis, we argue that the European Union should instead, and in agreement with the principle of subsidiarity, allow member states more flexibility.  相似文献

This paper draws on Kingdon’s multiple streams model of problems, policies and politics to explain the process of automobile dependence reversal path in urban transport planning in Curitiba, Brazil. What significantly contributed to the automobile dependence reversal path was a diverse coalition of actors who mobilized capabilities and structures to exploit policy windows at different periods of time and even tried to trigger policy windows within the milieu of problems, policies and politics of Curitiba to implement policies on public and non-motorized transport. The Curitiba experience shows that addressing the embedded problem of automobile dependence sometimes requires innovative and strategic responses within the intricate political, policy and urban planning dynamics of a city.  相似文献

Taxis share a high proportion of urban traffic volume and contribute a large proportion to urban air pollution. This paper addressees this context by exploring urban taxi air pollution emissions and possible reduction countermeasures. Based on a survey of Harbin taxis, we have developed different urban taxi pollution emissions models and considered taxi passenger occupancy and taxi average vacant ratio. To reduce taxi air pollution emission, this paper sets a reduction goal and puts forward three kinds of transport management policies. These are taxi market regulation, introduction of electric and Liquefied Petroleum Gas powered vehicles, and the introduction of dial-a-ride services. The paper provides recommendations for managing urban taxi development using these strategies.  相似文献

Following International Air Transportation Association requirement for all member airlines and airports to have a security management system (SeMS) beginning 1 March 2007, many organizations are looking to learn from safety and quality management systems. Without specific guidelines or best practices, organizations are forced to imitate these processes designed for different goals. Since safety, quality, and security environments operate on radically different principles, SeMS implementation must take a different tack. The case of the Canadian Air Transport Security Authority illustrates the importance of a custom-designed program that meets public and corporate needs. The Authority is responsible for security screening of passengers, non-passengers, and baggage within selected airports. As a crown corporation with a precise statutory mandate and regulatory environment, the development of a SeMS illustrates some of the key problems for the application of SeMS to larger organizations.  相似文献

Due to growing traffic demand, enormous investment requirements and high fiscal pressures, China has witnessed a reshaping of financing policies in large transport infrastructure projects from public financing to Public-Private Partnerships. As a result, the provision of transport infrastructure services in China has been steadily moving from the realm of government to that of private sector. In the same period, governments at the central and regional levels were actively engaged in this institutional transition by devising corresponding policies and enacting new laws and regulations. However, in late 2009 it became clear to the authors of this article that there has been a tendency of rolling back private participation in transport infrastructure and service because of various forms of opportunistic behavior on the part of some private players and malpractices among some governmental officials in their interaction with private players, and in relatively recent a number of large transport projects have been granted to state-owned enterprises. Therefore, the purpose of this article is to analyze and explain the processes of rise and fall of Public-Private Partnership in China. We argue that the adoption of Public-Private Partnership in China is a path-dependent process rather than some economic optimum advocated by a variety of international organizations. Specifics of wider Chinese political, cultural and institutional context are recognized as important factors that influence the performance of Public-Private Partnership. Effects of decisions made under transitory conditions can persist long after those conditions have vanished. In addition, these historical legacies are important in understanding contemporary use of Public-Private Partnership in China, and they are also the origins from which the sub-optimal statuses are often led.  相似文献

This paper examines the provision of mobility options being one of the important policy areas vital to addressing transportation accessibility of the elderly. A provincial analysis, taking the case of the Province of Ontario in Canada, is warranted given that the country’s highly decentralized system puts provincial policies at the forefront in meeting this challenge. The paper evaluates the important progress made in this policy area and stressed the need to go beyond the traditional policy focus on the less able-bodied elderly and consider the increased heterogeneity of the elderly population with respect to lifestyle, preferences, resources, health and physical abilities. While significant efforts have been made, a more explicit recognition of population aging in Ontario’s transport policy motivation that could strongly influence transport strategies and investments attuned to the mobility concerns in an aging society remains to be seen. The paper summarizes the general concerns in the literature, policy developments, and the challenges in crafting solutions in terms of policy and research for Ontario and other regions with similar institutional setup.  相似文献

This article explores the spatial and development implications of the Pan-European Transport Axes in the Balkans. For that purpose, the potential Development Poles and Axes are determined, on the basis of size, the location of cities, their interconnection and their role as hubs of the Pan-European axes. This is achieved by means of the formation and implementation of a methodology based on the use of special statistical applications. According to data analysis, three geographical units arise: Central Core, Peripheral Zone, Perimetric Zones. In the analysis that follows, Advantages, Weaknesses, Opportunities and Threats are examined in each case and suggestions are made as regards the policies required.  相似文献

Whilst the theory on road pricing is well developed there are only a few schemes operating worldwide with others which have failed to be implemented. One scheme which has received relatively little attention is the Controlled Vehicular Access System (CVA) recently implemented in Valletta, Malta. This paper draws on the experience of Valletta with a move from a fixed annual charge (V-licence) for access into the city to a time-based road user charge implemented in May 2007. The aims of this paper are to identify the reasons why a fixed charge was initially introduced; to review the literature related to implementation of road user charging schemes around the world; to compare the V-licence with the CVA and identify the issues relating to the change from one scheme to another. Through the direct involvement of one of the authors in the design and implementation of the road user charge in Valletta, this paper is based on archival data, direct observation and qualitative interviews. This paper concludes on what lessons can be learnt from the case of Valletta for other cities contemplating the introduction of a road user charge.  相似文献

This paper seeks to improving our understanding of air passengers’ decision-making processes by testing a conceptual model that considers service expectation, service perception, service value, passenger satisfaction, airline image, and behavioural intentions simultaneously. For this testing, path analysis via maximum likelihood estimator is applied to data collected from Korean international air passengers. Service value, passenger satisfaction, and airline image are each found to have a direct effect on air passengers’ decision-making processes.  相似文献
