Rail travel and the Leisure market in great Britain

The purpose of this paper is to examine the factors influencing and inducing leisure travel; to convey the sensitivity of rail travel receipts to the performance of the economy and more particularly family and personal disposable incomes; to examine the potential for further market research; and finally, to determine ways and means of attracting marginal revenue in the sustainable recreation/tourism sphere to a major public sector asset.

The paper focuses on leisure marketing by Britain's national railway corporation, British Rail (BR), and the relevant activities of its three passenger business sectors: Network SouthEast (NSE), which operates regional and local services in London and the South East (though not the London ‘tube’ system); Regional Railways, which operates regional and local services elsewhere in Great Britain; and InterCity, which operates the long distance express services.

The paper reviews BR's fares promotions of recent years and in particular draws on some examples taken from Regional Railways. This sector is now the only business of British Rail which in principle is subject to a significant public grant, to meet the obligation of a minimum level of service on social grounds. Of the other two passenger businesses, Network SouthEast receives a grant but the current intention is that it should operate on a breakeven basis from the 1992/93 financial year; InterCity runs on a purely commercial basis.     

Determining the effects of scheduling on automated automobile guideway utilization

This paper develops an analytic approach for measuring the effect of vehicle scheduling and of metering methods required to balance entrance rates among stations on lane capacity utilization of automated automobile guideways. The scheduling process at each entrance is represented by a probabilistic model which generates a system of nonlinear equations. The solution of this system yields the maximum steady state input rates at the entrances to the guideway system. The method developed is applicable to network configurations in which a small number of merges must be scheduled for each vehicle before it enters the guideway. It is demonstrated by application to a corridor guideway serving a major activity center during peak inbound demand, and also it is shown how the approach may be extended to more complex networks.     

New insights from fractional order skyhook damping control for railway vehicles

Active suspensions for railway vehicles have been a topic of research for a number of decades and while their applications in service operation are limited, it seems clear that they will in due course see widespread adoption. Railway suspension design is a problem of compromise on the non-trivial trade-off of ride quality versus track following (guidance), and the skyhook damping control approach has been paramount in illustrating the potential benefits. Since skyhook damping control, various advanced control studies appeared contributing to redefine the boundaries of the aforementioned trade-off. Yet there is no study on the impact of fractional order (FO) methods in the context of skyhook railway active suspensions and in particular related to skyhook damping control. This is the area to which this paper strongly contributes. We present findings from a current project on FO controllers for railway vehicles active suspensions, in particular work on the effect of FO methods in basic skyhook damping control schemes, i.e. pure and intuitively based skyhook. First, we present a brief review of conventional skyhook damping control and then proceed to a rigorous investigation of the impact of FO on the ride quality/track following trade-off. The relevant benefits from FO methods are appraised and new insights highlighted.     

Empowering professional women in the Maritime World: the WMU contribution

Promoting the increased participation of women in the economic fabric of developing countries is a fundamental goal of the United Nations. The International Maritime Organization (IMO) and the World Maritime University (WMU) are working to bring about a sustained change in gender imbalance in the maritime sector, to bring the skills and expertise of women to bear on a vital global industry. This report details WMU’s strategies to date, the conference held by WMU in April 2008, Empowering Professional Women in the Maritime World, and the Conference Declaration and Resolution supported by members of the IMO Technical Cooperation at its 58^th session in June 2008.     

Aesthetic markets and a new automated people mover

Research literature suggests that aesthetic response toward a transportation system may be colored by non-aesthetic values. Photographic depictions of downtown street scenes with and without automated people mover guideways were shown to various community groups. Measures of external utilities—stakes in the local community and in public transportation—bore no relationship to aesthetic assessments of either guideway scenes or street scenes without a guideway. In contrast, aesthetic background and interests depressed evaluations of both guideway and non-guideway scenes. Aesthetic background evidently influences aesthetic assessments of elevated guideways in urban streets far more than do non-aesthetic utilities. This suggests that planners of new transportation systems need to address aesthetic impacts apart from other impacts and that aesthetic criteria will be applied more stringently by some community groups than by others.

Over the past generation seaports have undergone a transformation from traditional cargo handling to logistical support centers and changed from bulk shipping and processing to high value-added management centers in an increasingly competitive global environment. Many have reorganized to become leaders of their region's economic development strategies. This paper reviews these changing roles and their impact on organizational issues. This organizational assessment is applied to the port of Kaohsiung and its envisioned role as a commercial hub and operations centre on the Pacific Rim. Issues such as split lines of responsibility, authority and jurisdiction across different levels of government are considered. Competing goals such as economic development, urban waterfront development, metropolitan urban structure, logistical integration, and infrastructure investment are discussed in this context.     

Modelling the hydrodynamics and ecosystem of the North-West European continental shelf for operational oceanography

This paper outlines an approach to complex spatio-temporal marine ecosystem modelling as applied to the North Western European Continental Shelf. The model presented here combines an eddy-permitting (approximately 6 km horizontal resolution) baroclinic model, the Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS), with the European Regional Seas Ecosystem Model (ERSEM). This has been run within an operational framework using operationally available high resolution atmospheric and lateral boundary forcing, allowing hindcast and near-real time nowcast simulations to be performed. The modelled surface temperature and chlorophyll distributions are presented, and interannual variations discussed. Validation of both the physical and ecosystem submodels show the system to be effective, whilst highlighting areas where improvements in the system can be made. Distinct regional differences in predictive skill are shown. The system presented is ready for operational implementation to provide products and services for use both scientifically and in coastal zone and shelf seas management activities. A programme of work to update the system is already in place.     

车载轮缘润滑系统

在小半径曲线上,轮缘润滑具有一系列优点.撇开对减轻轨道和车轮磨损的需求不谈,润滑起码可以减小轮缘与轨道面接触时产生的啸叫声.噪音现在已成了铁路环境必需考虑的一个重要因素.啸叫声是由摩擦转换成声音而产生的,所以润滑也可以降低燃油的消耗量.     

Exploring gendered cycling behaviours within a large-scale behavioural data-set

Analysing over 10 million journeys made by members of London's Cycle Hire Scheme, we find that female customers' usage characteristics are demonstrably different from those of male customers. Usage at weekends and within London's parks characterises women's journeys, whereas for men, a commuting function is more clearly identified. Some of these variations are explained by geo-demographic differences and by an atypical period of usage during the first three months after the scheme's launch. Controlling for each of these variables brings some convergence between men and women. However, many differences are preserved. Studying the spatio-temporal context under which journeys are made, we find that women's journeys are highly spatially structured. Even when making utilitarian cycle trips, routes that involve large, multi-lane roads are comparatively rare, and instead female cyclists preferentially select areas of the city associated with slower traffic streets and with cycle routes slightly offset from major roads.     

A Review of the Evolution of Shared (Street) Space Concepts in Urban Environments

Abstract

This paper aims to clearly establish the origin and evolution of the shared space concept from a New Zealand perspective by reviewing the literature in the disciplines of both urban design and transportation engineering. The review process involves investigating the use and function of a public road space in the context of the changing of public expectations and how this can relate to a number of interconnected street design approaches (e.g. traffic calming and self-explaining roads (SERs)). These approaches have been used to minimise the influence of motor vehicles since the beginning of the automobile era. The shared space concept, when applied in public road environments in activity centres, has increasingly been embraced by urban planners, transportation engineers and regulatory agencies. A shared space diverges from a conventional road where all road users are encouraged to legitimately occupy the same road space with little physical separation. To achieve this in a safe and efficient manner, the design aims to reduce the dominance of the motor vehicle by promoting pedestrian and cycling activity and utilising the road space as a ‘place’ in addition to its ‘transport’ mobility and access purposes. Given the fundamental conceptual differentiation between a traffic-calmed street and a shared space, the paper argues that there are certain design elements, constituting a shared space, and without them, it would be difficult for a public street to function as a genuine shared space for all road users.
