The assessment of methodologies to prioritise the construction of new high-speed rail (HSR) corridors has recently become a key issue for transport planners in countries like the U.S., where HSR does not exist. In a climate of financial instability since the onset of the global crisis of 2007–2008, support for new projects is being eroded by serious concerns over the extremely steep costs of high-speed rail, and there is a need for the scientific clarification of the procedure for prioritizing construction.In 2009 a new ranking methodology was developed and applied to 30,000 city pairs in the U.S. to determine their suitability for high-speed rail investment. The existing literature on ranking tools for prioritising HSR corridors is practically non-existent, and, as none of these U.S. lines has been built or put into in operation, this methodology has not been validated. The main aim of this paper is to contribute to these ranking models and highlight their importance in the HSR planning process. The preliminary ranking tool described in this work has been validated using data from the current HSR Spanish network. The results confirm the consistency of the model as a first approach to ranking pairs, mainly for the top O–D relations; however the model has some drawbacks chiefly due to the type of variables used, and their assigned weightings. Finally, some specific improvements are proposed for this ranking approach in order to provide policymakers with a useful tool when planning the construction of new HSR networks. 相似文献

This paper has been written in response to the Viewpoint contribution by the author Button (2012) entitled: “Is there any economic justification for high-speed railways in the United States?”. In this article, the Spanish HSR high-speed rail network is used as an argument against certain HSR investments. Several of the data presented by the author are misleading and some of the information given in connection with Spain is incomplete. As the Journal of Transport Geography is widely read by policymakers and the scientific community, Button’s misrepresentation could cause serious damage. We therefore set out to clarify the data used by Kenneth Button and to explore some points in greater detail, although in no case eschewing criticism of Spain. Although excessive Spanish investment in public infrastructure over the last twenty years has probably had a negative impact on the real estate bubble, investments in HSR infrastructure in Spain have specifically been accompanied by two particular facts that need to be distinguished from other countries’ experience. These facts cannot be overlooked and will be discussed in this paper. They relate firstly to the total amount of European funds used in HSR construction and secondly to the technological and scientific innovations developed in Spain linked to the HSR market. 相似文献

浅析我国地方税制运行情况与存在问题 总被引:2,自引:0,他引:2
随着1994年分税制改革的实施,我国初步建立了现行的地方税收制度。但由于受到当时的社会政治、经济条件的限制,分税制改革还带有明显的过渡性质,地方税制的设计与建设方面也就难免存在一定的缺陷。通过分析我国现行地方税制的运行情况以及地方税收入对地方财力的满足程度,提出我国现行地方税制存在的一些具体问题,希望在新一轮地方税制的改革中能引起足够的关注和重视,为尽快建立健全规范、完善、相对独立的地方税制贡献一份薄力。 相似文献
