Full reliance on conventional forms of bus transit for peak hour needs reduces industry productivity and creates major new subsidy requirements. Restructuring of transit is needed to enable paratransit integration and other innovations than can improve efficiency. This paper discusses the industry's long-term neglect of efficiency and describes subsidy policies that would promote necessary changes.  相似文献

Innovation, organizational capabilities, and environmental values combine to determine institutional change for a major marine port. This conceptual framework is applied to the case of dredged material management for the Port of New York and New Jersey. During the century under review, the institutional setting has changed significantly with: (1) environmental considerations moving from nearly irrelevant to central: (2) the number of interests and organizations increasing; and (3) the decision processes becoming far more complex. Ultimately, the new institutional setting influences organizations and individual decisions. As a result of the changes, the practice of dredged material disposal in ocean waters has been limited based on the level of bioaccumulation of selected contaminants. In response to institutional changes, ports requiring deepened channels must rapidly innovate to meet new environmental obligations for material disposal in order to enhance organizational capabilities necessary to maintain competitive advantages in maritime commerce. Successful marine ports will anticipate and meet new societal expectations related to the environment as a condition for continued legitimacy. Collectively these changes imply that ports have moved beyond a carefully circumscribed mission of transportation and economic development to that of a prominent user of coastal space with broad obligations to the public.  相似文献

Several issues concerning the implementation and operation of high-speed rail service in the Detroit-Chicago corridor are identified and discussed in this paper. The primary concern is whether such a service is likely to be attractive enough to induce the private sector to provide it. While the outlook for private operation appears pessimistic, consideration of a broader range of potential benefits (e.g., direct and indirect employment) may justify public involvement and investment.  相似文献

Since paper freight-hedging tools were introduced to counter volatile tanker freight rates, the hesitant uptake of tanker Forward Freight Agreements (FFAs) has been attributed to traditional risk seeking propensities amongst tanker owners, naturally reluctant to hedge against risk. To test how far the well-documented generic determinants and incentives for corporate hedging could explain this hesitation in the tanker market, the attitudes of tanker owners and charterers towards freight hedging, risk and perceptions of FFAs, were surveyed. Although FFAs were widely viewed as an important development, some respondents were unaware of their function and a majority had not used them. The link between freight hedging activity and participants' risk aversion was not clear-cut, but with market liquidity critical to raising FFA usage improved technical education is essential to widespread acceptance  相似文献

The objective of this paper is to compare the ecological footprint for travel-commuting patterns for the residents of an Irish city-region, that is Limerick city-region, in 1996 and 2002. Scenario building, based on ecological footprint analysis, is used to estimate the impact of different policy choices for 2010. The optimal policy mix for sustainable travel is proposed and consists of a mix of reduced demand through travel demand measures, better spatial planning and technological improvements in fuel economy.  相似文献

There is growing interest in establishing additional evidence, under the umbrella of the wider economy impacts of transport infrastructure projects, to support transport projects in general and public transport projects in particular that struggle to obtain benefit–cost ratios sufficient to gain the support of financial agencies. This paper focuses on one element of wider economy impacts, often referred to as effective economic (employment) density or employment agglomeration impacts, and another, less usually identified, social accessibility impact (SAI) which we refer to as effective social density, which in broad terms provide, correspondingly, evidence of the potential gains in work-related output (often referred to as productivity gains) and potential gains in non-work-related outputs. Both are associated with gains in individual and household benefit attributable to improved accessibility to services linked with populations and particular locations. The SAIs may capture some of the induced benefits in those jurisdictions where these are included routinely in benefit–cost analysis, and the methodology here is most appropriate to those settings where an existing calibrated demand curve may not be available. Using the proposed high speed rail (HSR) project between Sydney and Melbourne as the empirical setting, we identify economic agglomeration and social accessibility benefits for work and non-work related activity respectively. We find the former to be relatively small compared to the significant gains associated with non-work related travel activity, suggesting the greatest benefits associated with HSR, especially for those residents outside of the major metropolitan areas, will be non-work related travel activity.  相似文献

This article discusses the employment of Kiribati seafarers on German owned and flagged shipping. The authors examine the origins of the German shipping industry sponsored training and recruitment programmes on the Kiribati atolls. The implications of the creation of a manorial ‘internal’ labour market for German container shipping in the South West Pacific is assessed. The impact of labour participation in the international shipping industry on Kiribati's former fisherfolk is also examined.  相似文献

A new transportation system is described. CyberTran is a steel wheel on rail system designed to travel on elevated guideways, utilizing large numbers of 6 to 20 passenger automated vehicles weighing less than 10,000 pounds. The benefits from these light weight vehicles include dramatically reduced system cost and increased passenger appeal. The system described has been prototyped and tested at the Idaho National Engineering and Environmental Laboratory, a U. S. Department of Energy Research and Development Laboratory.  相似文献
