In an effort to reduce the adverse impacts of the car and promote sustainable transport in Latin America, some governments have either implemented travel demand management policies or have considered ways of directly reducing the number of vehicles in congested areas. While demand management measures have been promoted in a small number of countries, including vehicular restrictions as well as the promotion of public transport modes, there are currently no congestion pricing programmes in operation in Latin America. This paper begins with an overview of travel demand management, including its principal aims as well as its primary objectives within the Latin American context. It discusses past efforts to promote traffic restraint and perspectives for developing congestion pricing schemes in both São Paulo and Santiago. Finally, it examines the potential role of congestion pricing as a demand management tool. While it is one of the most effective demand management measures in the industrialised world, a number of barriers currently prevent it from being widely adopted in Latin America.  相似文献

The workshop included presentations of nine papers covering very different types of situations and transitions. Some papers were region specific (Russia, Middle East, Asia, Europe, and two from Latin America) and others were of general applicability. The discussion highlights that virtually all cities and regions will go through one type of transition or another, sooner or later, and that the study of such transitions provides a very rich learning environment. The most important conclusion has been that in many cases the stability of supply and accessibility to public transport by all population segments is more important than competition and ownership.  相似文献

Latin America and the Caribbean have evolved as a region of increased interest for the maritime and port industry as well as for academic research. Maritime transport activity in the region has experienced sustained growth rates over the last decades, resulting in ever-increasing demand for maritime services and port infrastructure. At the 2011 Annual Conference of the International Association of Maritime Economists (IAME), Latin America received significant attention. This editorial responds to growing research by giving a brief overview of the current situation and contemporary issues in maritime transport within the region. It also introduces the six selected papers for this Special Issue.  相似文献

The World Bank urban transport strategy review, “Cities on the Move” analyzed urban transport problems in developing and transitional economies and articulated a proposed strategy framework for national and city governments. This paper describes how the urban transport problems of the developing world have changed in the last decade and assesses the extent to which the strategies recommended in 2002 have been successfully implemented. It shows that progress has been widespread in some areas – particularly in mass transit analysis and investment and some environmental policies – and that there have developed some good planning and public transport practices in a smaller number of model cities. But more strategic institutional and policy issues, including the mobilization and regulation of private sector initiative in meeting infrastructure and public transport supply deficiencies, have tended to be poorly developed. Above all, the growth of medium sized cities with weak institutions and finance highlights the need for the international development institutions to put greater emphasis on helping those cities by dissemination of best practice in strategic transport planning and traffic management.  相似文献

A few cities in some of the larger developing countries in Latin America and Asia have made increasing use of multi-year concessions or franchises, competitively awarded to private companies, for construction and operation of urban transport infrastructure and for provision of public transport services. In view of the strong prospective growth of developing-country cities with large transport needs, and the rise in the emerging economies of potential new sources of private capital, it is important to see how effective PPP has so far been in this area. The experience is analyzed principally by thorough comparative review of what has actually happened for some of the main users to date: Bogotá, Santiago, São Paulo, Seoul, and several cities in both China and India. Despite delays and mistakes that have been made in development of most of the projects, the overall results, already delivered and in prospect, are very positive and urban public transport is benefiting substantially, with significant side effects on poorer people's access to work and to services, air pollution levels and road accident rates. The widest and most important advantage of the PPP arrangements, as compared with more conventional short-term contracting, is found to be the innovations, technical and managerial, developed, and, in particular, the mutual capacity building of the countries' private and public sectors and their more effective interaction. The experience in the six countries covered suggests that other developing-country cities may be best assisted to develop sound urban transport PPPs more rapidly through provision of help on chosen items among 7 elements that have proved particularly crucial but sometimes weak in the projects reviewed: Civic consultation systems, Land-use/Transport strategic planning, Land/property market management, Monitoring systems, Progressive policies, Economic regulation, and Public institutional framework for PPPs.  相似文献

Over the preceding decade, the World Bank committed about US$7.5bn in loans for urban transport projects in its client countries, involving total project costs of nearly US$13bn. Projects are designed by the client city/national governments and the World Bank in an interactive, give-and-take process. As is common in development finance, urban transport projects entail an investment program and a set of policy and institutional initiatives. A majority of Bank-funded operations in this period focused on public transport modes. A clear and overarching strategic thrust is evident, favoring private delivery of services with a strong public role through city-specific regulatory agencies. Depending on the context, projects involved efforts to introduce private operators and competition into an all-public set-up, or tighten up weakly regulated, “informal” public transport markets. A notable feature of many projects in the latter context is the use of investments in bus rapid transit infrastructure to reach multiple goals: improve transport services, maintain affordability for low-income passengers, attract new passengers, reduce negative environmental impacts, and leverage complementary reforms of policies and institutions. The Bank’s program in China, unique in its local context of a dynamic urban society moving away from a near-universal reliance on bicycles, initially did not focus on public transport but on urban roads and traffic management. Towards the end of the last decade, the motorization process and the outlook of decision makers entering a more mature stage, projects in China started to converge towards what the rest of the Bank’s program was doing – searching for a more sustainable path to urban transport development.  相似文献

During the last forty years, Santiago has experienced a series of drastic changes in public transport policies. These changes have ranged widely, from total deregulation to processes that concentrated the management of public transport within the hands of the public sector.  相似文献

The Chilean government decided to modernize Santiago's entire public transport system, integrating the underground and the private bus networks based on a structure of trunk and feeder services, and a fare-payment by touchless smart card. The new, integrated transit system, known as Transantiago, very soon ran into serious problems that alienated much of its user base and significantly lowered the government's approval ratings. This paper recounts how Transantiago was planned and designed and then discusses its evolution after implementation. It concludes with suggestions for the Transantiago authorities and lessons to be learned from this traumatic process.  相似文献

The diagnosis for urban transport sustainability depends on the context of different regions worldwide. We focus in this paper on West and North Africa which reveal similarities but also structural differences which are explored further. The importance of paratransit in its various forms is strongly observed in sub-Saharan Africa and to a lesser extent in North Africa. The attempts to regulate and organise this sector have been difficult; one interesting experience in Dakar occurred during a programme of fleet renewal. In parallel it is observed that there are positive but insufficient experiences of public transport authorities in some cities (Dakar, Abidjan) and similar projects postponed in other cities because of the institutional problems. One also observes the constant difficulties of designing sustainable schemes for bus companies. An answer to this crisis has been found in North Africa, through investment in new mass transport systems. However, mass transport projects in West Africa are very weak in comparison. The gap between public transport costs and income levels there remains a major obstacle to sustainable mobility exacerbated by the poverty of a significant part of the urban population in West Africa. Two other critical factors are also identified affecting sustainable mobility requirements, namely, the urban sprawl and increasing energy costs. Finally the conclusion recommends the use of research and expertise networks in order to help the design and the implementation of suited solutions.  相似文献

A number of South African cities are planning integrated public transport networks that rely on the introduction of Bus Rapid Transit (BRT), in line with similar trends to expand or upgrade public transport services in emerging and industrialised urban transport markets around the globe. In addition, BRT in South Africa is being used as a mechanism to drive reform in the dominant yet highly fragmented paratransit sector, inspired by similar processes particularly in Latin American cities such as Bogotá, Mexico City, and Santiago de Chile. Thousands of paratransit operators would have to formalise their businesses, or merge into new or existing operator entities in order to participate in the new systems. There is, however, an absence of accessible business plans and regulatory regime proposals around which paratransit can be engaged to convince it to alter its current modus operandi. A large number of national, regional and local paratransit groupings have furthermore indicated their resistance to the planned networks on the grounds of insufficient consultation, an unclear future role in the system and employee redundancies. Should this deadlock not be resolved, it seems unlikely that the planned networks will be realised in the proposed timeframes, if indeed at all. This paper investigates the South African passenger transport policy framework that has contributed to the current deadlock, and explores appropriate approaches to engaging paratransit operators on a system of contracting, competition and ownership that recognises the sector’s aspirations and fragmented nature, yet contributes towards improved passenger transport services. It is the authors’ view that paratransit reform is a highly context-specific process, even at the sub-city level, and that this could prevent transferring paratransit regulatory and integration approaches across countries, and even cities in the same country, without adaptation to local conditions.  相似文献

This paper presents findings of a freight transport study carried out for Mumbai city (India). Based on the case study of lunch box delivery system organized by the Mumbai dabbawalas, demonstrated that an informal sector was capable of developing an urban logistics system that was precise, reliable and affordable to the middle class society in Mumbai. These facts suggest an approach based on adapting logistics solutions harmoniously to the urban landscape, public policy, infrastructure and skill sets of the company’s employees in order to be attractive to the end customer, offering a good match between supply and demand i.e., consumer and producer satisfaction. At the same time logistics solutions should evolve continuously in order to be attractive to the core customer base and should be customer driven. These basic management principles can be applied in the management of other urban logistics companies in the world over.  相似文献

This research examines the potential for short sea shipping services on the east coast of North America, and focuses on the factors that freight shippers use to choose a transport mode. While there is significant literature available on modal choice and carrier selection, very little examines the effect of splitting the business on the choice that shippers specifically make between short sea and trucking options. Contrary to existing literature, we find that shippers' perceptions of short sea are favourable in this market. We also identify a new method of collecting data on how companies split business in these decisions.  相似文献

Bus based public transport has enjoyed revitalisation in many urban areas but outside large towns and cities its provision and quality remains erratic. Many rural settlements have infrequent services giving rise to social exclusion through transport disadvantage.The UK Government highlighted a need in Towards a Sustainable Transport System (2007) for radical new thinking on rural accessibility to help meet goals of quality of life and accessibility for all and to help meet the challenge in finding carbon friendly ways of meeting rural transport needs. This paper reports work undertaken for the Commission for Integrated Transport, an advisory body to UK Government, on how shared taxi-schemes could be developed within a deregulated environment to meet rural accessibility needs. This is based on an analysis of institutional barriers and comparison between successful mainland European schemes and UK schemes. The paper considers economic viability and the levels of subsidy currently used to provide accessibility in rural areas to show the potential for making current expenditure on rural transport in the UK ‘work harder’ to deliver a collective taxi-based service as part of the public transport mix so as to increase rural accessibility.  相似文献

This paper attempts to bring out the lessons learned from implementation of the Mumbai Urban Transport Project (MUTP), a World Bank financed project. While some of the problems and many solutions may be case specific, the lessons learnt would be of use for other similar interventions especially in similar urban settings. Even complex engineering challenges are generally easy to be surmounted, when compared with the bigger challenges like resettling the project affected peoples, managing several stake holders and institutions, bringing them together and they agreeing to do things differently.  相似文献
