PPP模式在城市轨道交通建设中的应用 总被引:18,自引:0,他引:18
目前中国34个人口过百万的城市中,有20个城市正在建设和筹建轨道交通,以解决日益凸现的公共交通问题,形成兴建城市轨道交通的热潮。城市轨道交通作为一种基础设施,长期以来采用以地方政府财政资金为主导的财政投融资模式。然而轨道交通造价高昂,资料表明,“十五”期间国内用于城市轨道交通建设的投资将达2000亿元。 相似文献

为了不走西方"先污染,后治理"的老路,我国提出了工程开放要与生态保护并举的方针政策,这交通环境保护已经提到了十分重要的战略位置。交通行业自1973年开始行业环境保护工作以来,越来越多的人意识到环境保护不仅关系到交通的自身发展,也关系到国民经济和社会发展的全面进步,随着交通环保理念和环保技术逐渐得到认可和广泛的应用,道路相关建设考虑的重点也随之发生转变,由从前的以人为中心,以人类获得最大利益为交通建设出发点 相似文献

This paper explains the theory in support of total cost analysis (TCA) to compare transportation system alternatives. The full costs of each alternative are first aggregated, including travel time costs and monetizable environmental and social costs. Many costs which are considered on the benefits side of the equation in benefit-cost analysis (BCA) as "cost savings" are brought over to the costs side. Total cost differences among alternatives are then traded off against their estimated non-monetized benefits or impacts, just as a consumer trades off product quality against cost before deciding which product he or she will buy. One advantage of TCA over traditional BCA is that the concept of "total cost" is more easily understood by the public and by political decision-makers than BCA concepts such as "net present worth", "benefit-cost ratio" and "internal rate of return". A second advantage is that there is no suggestion that all "benefits" have been considered; decision-makers are free to use their own value judgements to trade off total cost against non-monetizable social, environmental and economic impacts, just as they trade off quality and convenience against cost when purchasing goods and services in their roles as consumers. The TCA approach is demonstrated in this paper through a case study of two systemwide alternatives for the Baltimore, MD urban area. 相似文献

Domestic and industrial sludge generated at wastewater treatment facilities is considered a potential biomass source for producing biodiesel. However, transportation of large amounts of sludge from wastewater treatment facilities to a biorefinery is expensive. The objective of this paper is to identify the proper transportation mode to use as a function of the volume shipped and transportation distances. Currently, sludge is mainly shipped by truck and pipeline. We estimated that the fixed and variable cost components of pipeline transportation for a volume such as 480 m3/day and a distance of 100 miles are $0.116/m3 and $0.089/m3/mile, respectively. We estimated the biomass (sludge) transportation cost per gallon of biodiesel, and observed the changes in these costs as a function of distance traveled and volume shipped. The outcomes of this study have the potential to help biofuel plants make better biomass transportation decisions, and consequently reduce the price of biodiesel significantly. 相似文献

Abstract This paper computes the cost of traffic congestion in the city of Antofagasta in Chile. A microsimulation is implemented where all the agents of the system travel across the transport network. The congestion cost is computed through the aggregation of the opportunity cost of people waiting within the transport system, as a consequence of traffic congestion. Monte Carlo experiments produced an approximated congestion cost of US$1.02 million during a typical working day. Moreover, the simulation provides useful information about the average traveling time for the 14 districts of the city. 相似文献
