In this paper a project undertaken by the author is described to illustrate modifications which may be necessary to the type of analysis given in an earlier paper [1] when difficulties arise from various practical considerations. The problem examined deals with the installation of unloading facilities at a purpose-built iron ore terminal at a steelworks. However, some of the data quoted has been coded to preserve confidentiality. The project was bedevilled by an unusual number of uncertainties; to appreciate these it is necessary to view them in relation to the situation existing at that time. 相似文献

This study compares the contributions to policy change made by two Regional Citizens’ Advisory Councils that participate in the environmental management of the marine oil trade in coastal regions of Alaska. Both councils are remarkably well-funded and long-enduring examples of citizen participation in environmental policy. This study finds that both councils have applied their substantial funding resources to make significant contributions to policy change (policy contributions) in the marine oil trade of coastal Alaska. This study also finds that both councils have greatly magnified their policy contributions through collaborative efforts with many other organizations active in the marine oil trade of Alaska. Therefore, the overall policy contributions of the councils result from the joint application of council resources and collaborative efforts. 相似文献

The paper undertakes a cost‐benefit analysis of a disinvestment using readily available data and demonstrates that a relatively straightforward yet systematic approach can provide useful input to the decision‐making process. Despite various assumptions necessitated by the analysis, it is argued that the net benefits of the railway line retention are unlikely to be significantly sensitive to their variation within feasible limits. The most significant component in the analysis is seen to be the operative costing system and it is argued that this should be revised. 相似文献

Traveler behavior plays a role in the effectiveness of travel demand management (TDM) policies. Personal travel management is explored in this paper by analyzing individuals' adoption and consideration of 17 travel‐related alternatives in relation to socio‐demographic, mobility, travel‐related attitude, personality and lifestyle preference variables. The sample comprises 1282 commuters living in urban and suburban neighborhoods of the San Francisco Bay Area. Among the findings: females were more likely to have adopted/considered the more ‘costly’ strategies; those with higher mobility were more likely to have adopted/considered travel‐maintaining as well as travel‐reducing strategies; and those who like travel and want to do more are less likely to consider travel‐reducing strategies. These findings, when combined with those of earlier work on this subject, present a compelling argument for the need to further understand traveler behavior – particularly in response to congestion and TDM policies. 相似文献

Maximum time lengths of urban trips can be used to calculate major user benefits of transportation improvements. These benefits include those associated with reduced cost of travel, those associated with travel to additional destinations, and those associated with improved quality of destinations. Maximum trip lengths can be measured using techniques of psychological scaling. 相似文献

Abstract This article outlines the steps that have been taken to conserve the coast of Great Britain. It treats the subject historically and emphasizes the ways in which unofficial and official bodies have interacted. Apart from a few very restricted areas, the shoreline is open to all people. The siting of houses, chalets, and huts is strictly controlled. Problems arise from time to time as to the location of nuclear stations, oil storage areas, and similar installations; these issues are settled in full discussions at official inquiries at which all interests—official, business, and conservation–are represented. 相似文献

The signalling system affects the type of service that can be provided on any particular railway line. The aims set when it comes to designing these systems to operate a railway line are: to ensure safety of operation and to ensure flexible and efficient running. When building a line capacity optimisation algorithm, it must reach a compromise solution between two parameters: minimise the interval between trains and keep journey time as low as possible. This paper aims to describe the algorithm developed between METRO DE MADRID and CITEF (Railway Technology Research Centre of the Universidad Politécnica de Madrid – UPM) that allows the capacity of an underground line equipped with ATP Distance To Go systems to be studied and optimised. This algorithm facilitates the tasks of signalling design and optimisation. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

As leisure travel continues to grow, it has become a critical subject for planners and decision-makers since it significantly
impacts regional economic and social development as well as contributes to emission levels and congestion. Despite being a
significant percentage of our travel, however, leisure travel behavior is still not very well understood. The goal of this
article is to contribute to our understanding of leisure activity participation by considering leisure activity loyalty within
the travel context. In particular, this study focuses on one specific dimension of travel context: travel extent (i.e., whether
an individual participates in a leisure activity on a daily versus a long-distance basis). As such, this article first introduces
a unified conceptual framework for measuring leisure activity loyalties within a travel context, based on two distinct dynamics
of leisure loyalty behavior—destination attachment and activity involvement. Additionally, this article uses a unique 2001
NHTS dataset comprised of households’ daily and long-distance leisure activities to undertake a unique empirical analysis
of five distinct leisure activities using the conceptual framework and a copula-based model methodology. The findings confirmed
that households demonstrate significant loyalties to travel contexts across all leisure activities, especially resting and
sightseeing. 相似文献
