Bus based public transport has enjoyed revitalisation in many urban areas but outside large towns and cities its provision and quality remains erratic. Many rural settlements have infrequent services giving rise to social exclusion through transport disadvantage.The UK Government highlighted a need in Towards a Sustainable Transport System (2007) for radical new thinking on rural accessibility to help meet goals of quality of life and accessibility for all and to help meet the challenge in finding carbon friendly ways of meeting rural transport needs. This paper reports work undertaken for the Commission for Integrated Transport, an advisory body to UK Government, on how shared taxi-schemes could be developed within a deregulated environment to meet rural accessibility needs. This is based on an analysis of institutional barriers and comparison between successful mainland European schemes and UK schemes. The paper considers economic viability and the levels of subsidy currently used to provide accessibility in rural areas to show the potential for making current expenditure on rural transport in the UK ‘work harder’ to deliver a collective taxi-based service as part of the public transport mix so as to increase rural accessibility. 相似文献

Improving the efficiency of ship optimization is crucial for modern ship design. Compared with traditional methods, multidisciplinary design optimization (MDO) is a more promising approach. For this reason, Collaborative Optimization (CO) is discussed and analyzed in this paper. As one of the most frequently applied MDO methods, CO promotes autonomy of disciplines while providing a coordinating mechanism guaranteeing progress toward an optimum and maintaining interdisciplinary compatibility. However, there are some difficulties in applying the conventional CO method, such as difficulties in choosing an initial point and tremendous computational requirements. For the purpose of overcoming these problems, optimal Latin hypercube design and Radial basis function network were applied to CO. Optimal Latin hypercube design is a modified Latin Hypercube design. Radial basis function network approximates the optimization model, and is updated during the optimization process to improve accuracy. It is shown by examples that the computing efficiency and robustness of this CO method are higher than with the conventional CO method. 相似文献
