"This publication elaborates on how the specific characteristics of the different transport subsectors affect the potential for expanding the role of competitive markets. It defines the principal challenges currently faced by the transport sector as a whole as: (i) the completion of basic infrastructure networks and (ii) the provision of adequate maintenance for them. Future challenges may include: (i) increasing responsiveness to customer needs, (ii) adjusting to global trade patterns, and (iii) coping with rapid motorization. These challenges highlight the need to reform institutional and transport policy in order to support a better quality of life on a sustained basis. This book identifies some generally applicable principles and best practices as the foundation of a policy for more sustainable transport. Economic and financial sustainability requires that resources be used efficiently and that assets be maintained properly. Environmental and ecological sustainability requires that the external effects of transport be taken into account fully when public or private decisions are made that determine future development. Social sustainability requires that the benefits of improved transport reach all sections of the community. It is necessary to redefine the role of governments in the transport sector--the focus in transport policy must shift toward a market-based approach with the private sector taking on more of the responsibility for providing, operating, and financing transport services and infrastructure. The role of the government would therefore decline, but its importance as the enabler of competition and the custodian of environmental and social interests would increase. The World Bank Group's role will be to focus on institutional and policy reform; it can help governments fulfill their enabling and supervisory role in a freer transport market through more selective and focused technical assistance for building the capacity and skills needed by the public sector." -- Website.
