我国高速铁路建设面临的挑战 总被引:1,自引:0,他引:1
高速铁路建设有几条基本原则:第一是有人口稠密和密集的城市,而且居民的生活水准较高,能够承受高速铁路比较昂贵的票价和多点停靠的条件.第二是拥有较高的社会、经济和科技基础,能够保证高速铁路的施工、运行与维修的需要.第三是高速铁路建设和运行本身应该符合可持续发展的要求,正是因为这一条原则,高速铁路相对汽车和飞机更符合中长距离的客运要求,更节能环保.中国不仅幅员辽阔、人口众多,而且东部城市相对密集,工业经济发达.因此,中国的国情非常适合于高速铁路的建设. 相似文献

Tolls that vary based on time of day or congestion are gaining attention around the world as a potential travel demand management strategy that can shift peak period travel to off peak periods thereby contributing to peak period congestion relief. However, despite the widespread interest in the concept, there is very little empirical data available on the impacts of variable tolls on traveler choices and disaggregate models that can be used to predict traveler response to variable pricing are few. This paper reports on results from two bridges with differential time of day tolls in the Lee County area of Florida in the United States. Using travel survey data collected at these two bridges, discrete choice models of traveler response to the variable toll rates are estimated. The models indicate that travelers who are retired, have a low income, have flextime at their place of employment, or have a flexible travel schedule are more likely to alter their time of travel with greater frequency due to the variable toll. 相似文献

Information searching is an important subject in tourism literature, but the subject of information is not often prioritised in leisure-constraint studies. Studies of leisure-constraint-negotiation mechanisms are frequently undertaken at a general level and not at the level of specific-negotiation strategy. This exploratory study examines how aesthetic-image information value affects the negotiation mechanism at the level of time-management-negotiation strategy by measuring the intentions of Taiwanese residents to tour Thailand. Aesthetic-image value is found to moderate the relationship between motivation and intention in the negotiation process. This study thus bridges tourism information values and the leisure-constraint concept. 相似文献

As an important infrastructure connecting straits or rivers, the construction of fixed links has become an effective measure for improving traffic conditions and promoting socio-economic development in many countries and regions around the world. Thus, it has become a significant topic in the field of transport geography. Taking the Yangtze River Delta as its case area, this study proposes a spatial impact model of trans-Yangtze highway fixed links, consisting of three components: an accessibility model, modified gravity model, and traffic utilisation model, which are used to analyse, respectively, cross-Yangtze accessibility and changes to transport structure, cross-Yangtze urban interaction and changes to economic structure, and the utilisation relationship of fixed links. Making use of existing fixed links while planning and building new ones has become the basis for achieving regional integration and sub-regional cooperation in this area, the aim of which is to create the barrier-free circulation of elements. The results prove that this spatial impact model coincides with reality. The increase in the number of fixed links has significantly shortened cross-river travel time and facilitated a unification of north-south highway networks. It has also promoted the formation of a high-connection urban network along the river. Northern urban nodes have joined the southern economic circle and finally achieved north-south integration. There are complex relationships between fixed links and their hinterlands, showing obvious utilisation gaps between the links. The complete system of trans-Yangtze fixed links is comprised of several river crossing facilities and connected highways. The function of each link is related to its role in the regional highway network. From a small number of fixed links to the realisation of multiple trans-Yangtze bridges and tunnels with easy access to multiple arterial highways, a ‘many-to-many’ spatial pattern is created that ultimately leads to the evolution of regional transport and economic structures. 相似文献
