城市轨道交通项目融资的偿债能力分析

城市轨道交通项目融资的贷款人并不是项目所有者,不可能从项目的投资中获得股本收益。因此,当贷款人在考察是否为采用项目融资方式建设的城市轨道交通项目提供融资时,所关心的重点是项目未来的偿债能力。本文在分析偿债资金来源的基础上,构造城市轨道交通项目的现金流模型,并从贷款偿还期、债务覆盖率、利息覆盖率、债务承受比率等方面,对城市轨道交通项目融资的偿债能力进行分析。     

The European high-speed train network: Predicted effects on accessibility patterns

The principal aim of this paper is to evaluate the impact of the future European high-speed train network on accessibility, by reducing time distance between places and modifying their relative location. We compare the current situation with that foreseen for the year 2010, according to the Outline Plan of the European High-Speed Train Network, in order to analyse which areas will most benefit from construction and improvement of the infrastructure. It is hypothesized that the high-speed train will certainly bring the peripheral regions closer to the central ones, but will also increase imbalances between the main cities and their hinterlands. A weighted average distance indicator is applied for this purpose. This measure identifies the spatial distribution of accessibility in the area of study, emphasizing the infrastructure effects, and locates accessibility changes at the European level. A Geographic Information System (GIS) has been used to carry out this study.

武陵山片区旅游节点交通畅达性研究

区域旅游节点的交通畅达性对区域经济发展具有强劲的推动作用,区域旅游节点的交通畅达性优劣取决于内部的连通性和外部的可达性。文章基于因子分析法分别就高等级公路、高速公路、普铁、高铁(动车)、民航航线等因素对武陵山片区内各旅游节点的交通畅达性的影响进行了评价分析,对各旅游节点的畅达性进行了排名;并选取2010、2014、2018年等3个时间节点数据导入GIS生成3个片区旅游交通图。研究发现:①重庆、武汉、长沙、贵阳四大中心城市的交通连线支撑起武陵山片区的交通网络,片区旅游节点之间的畅达性逐步提升;②处于武陵山片区外围重庆、武汉、长沙、贵阳四大中心城市交通大廊道上的旅游节点之间畅达性处于片区前列;③同一省市或同一传统旅游线路的旅游节点连通性较好,分属不同省市的旅游节点之间连通性普遍较差;④历史上,山高谷深、交通闭塞,各地市自然旅游资源丰富多样,文化旅游浓郁独特,近年来,武陵山片区旅游发展与交通建设相互推拉,呈现良性发展。

Public bicycle as a feeder mode to rail transit in China: The role of gender,age, income,trip purpose,and bicycle theft experience

A marriage between public bicycle and rail transit presents new opportunities for sustainable transportation in Chinese cities. To examine determinants of public bicycle usage for rail transit access, an intercept survey of feeder mode choice among rail transit users was conducted near rail stations in Nanjing, China. Mode choice models were estimated with five feeder mode alternatives, including car, bus, walk, private bike, and public bike. By differentiating between public and private bicycle modes in the mode choice models, the study reveals the effects of personal demographics, trip characteristics, and station environments on public bicycle usage for rail transit access. Results show that female, older, and low-income rail commuters are less likely to use public bicycle to access rail transit. Rail commuters with bicycle theft experience and making school- or work-related trips are more likely to use public bicycle to access rail transit. Land use variables are largely insignificant in this study except that density shows a positive relationship with walking to rail transit. The results on demographic differences raise equity concerns when it comes to investing in public bicycle systems. Policy implications are discussed for Chinese cities to equitably boost public bicycle integration with rail transit.     

Operational performance of U.S. public rail transit and implications for public policy

In today's tough economic environment, governments at all levels face significant budget shortfalls and public rail transit systems must compete with other public services for government subsidies. It is critical that public rail transit systems be concerned with their operational performance and efficient use of resources. In this paper, we develop a methodology that measures a rail transit system's performance relative to that of other rail transit systems, compares its performance to an appropriate efficient benchmark system, and identifies the sources of its inefficiency. We analyze the relationship between public subsidies and operational performance of public rail systems and show an inverse relationship between subsidization and efficiency.
