宁高城际轨道交通线路技术标准研究

宁高城际高淳段作为江苏沿江城市群轨道交通网中的一条重要线路,联系了南京市主城区、东山副城、溧水区石湫镇和高淳区,承担南京市主城区与高淳区间的远距离轨道交通。前期系统制式专题研究确定,本线的速度目标值为120km/h,车辆选用B型车4辆编组。但我国尚无与之相应的轨道交通线路设计规范,因此实际设计中需要参照地铁或国铁相关规范。而本线线路的平、纵面设计参数与地铁和国铁均有较大差异,不能完全参考《地铁设计规范》或《铁路线路设计规范》,因此必须对本线的关键技术参数进行专题研究,根据本线的功能定位和特点选取合适的技术标准,计算出关键技术参数应用于工程设计。

Problems with certification and legislation

This paper discusses the vast growth of requirements directed toward mobile offshore drilling units attempting to be internationally certified. As a simplistic example, the regulations regarding heliports are examined with the pitfalls and benefits of an international standard discussed from the viewpoint of owner and operator. Recommendations contained in an International Maritime Organization resolution are suggested for use by the various regulatory bodies when dealing with new or amended rules. It is suggested that a more universal standard would evolve if the guidance of the resolution were heeded.

Do parking standards matter? Evaluating the London parking reform with a matched-pair approach

Minimum parking standards, which require developers to build a certain amount of off-street parking spaces, are increasingly criticized for leading to excess parking supply and automobile travel in recent years. However, due to the difficulty in identifying the policy effect, few empirical studies have directly and accurately estimated the effects of parking standards on parking supply. The present study examines a parking reform in London, UK, where minimum parking standards for residential developments were replaced with maximum standards in the early 2000s. Using planning application records, we match neighboring pre-reform and post-reform developments to estimate the effect of the parking standard switch and further identify the “binding” and “capping” effects of minimum and maximum parking standards. It is found that the parking reform in London has led to a reduction of approximately 0.76 parking spaces per unit in residential development applications, or 49% of the pre-reform level. Minimum parking standards seem to have a larger impact than maximum ones on parking supply that fell more upon inner city developments, while maximum parking standards have more influenced suburban neighborhoods. Market forces have played a major role in the decline of parking supply. The findings provide strong evidence for the market distortion effect of minimum parking standards.
