This chapter presents a summary of the findings of the workshop on ‘Analytical and Institutional Methods and Frameworks’. The paper discusses the nature of the analytical methods used in the papers presented and the purposes for which they were employed, which were generally to either assist in the planning and operation of public transport or to monitor the efficiency and effectiveness of transport services. Subsequent sections examine issues related to data collection and management, and the more general issue of institutional arrangements. Policy and research agendas needed to support further consideration of the subject are then identified. 相似文献

This paper explores the current state of coastal and inland shipping in Tanzania. It provides an overview of the state of ports and shipping in Tanzania, and the reasons underlying the present crisis of competitiveness in terms of both global pressures and national and regional dynamics. Problems of competitiveness are at least partially due to under-investment, management failures, skills shortfalls and difficulties in interfacing with the railway network. Less easy to resolve structural problems include the great imbalance between imports and exports, heightened regional competition and ongoing political instability in the Great Lakes region. 相似文献

As the controversy over Outer Continental Shelf (OCS) oil and gas leasing continues, with environmentalists and fishermen seeking to block or delay leasing decisions that they think will adversely affect their interests, the need for better estimates of the environmental costs associated with OCS development becomes increasingly apparent. Although high degrees of precision in such estimates may never be economic, let alone feasible, better knowledge would reduce the uncertainty surrounding the magnitude of such costs, and would make it easier to come to grips with the problem and reduce, if not resolve, the controversy. 相似文献
