论船舶登记的公信力

公信力理论起源于德国,是登记的理论基础。文中从物权的公示和公信力理论出发,剖析公信力理论的内涵、现实意义、在国外的适用情况,并联系我国船舶登记的实际情况,阐述公信力理论在我国建立的必要性和可行性,提出可通过引入船舶登记前置的公证程序和变更异议登记制度等途径进一步提高和完善船舶登记的公信力。     

Assessing the cost of transfer inconvenience in public transport systems: A case study of the London Underground

Few studies have adequately assessed the cost of transfers² in public transport systems, or provided useful guidance on transfer improvements, such as where to invest (which facility), how to invest (which aspect), and how much to invest (quantitative justification of the investment). This paper proposes a new method based on path choice,³ taking into account both the operator’s service supply and the customers’ subjective perceptions to assess transfer cost and to identify ways to reduce it. This method evaluates different transfer components (e.g., transfer walking, waiting, and penalty) with distinct policy solutions and differentiates between transfer stations and movements.The method is applied to one of the largest and most complex public transport systems in the world, the London Underground (LUL), with a focus on 17 major transfer stations and 303 transfer movements. This study confirms that transfers pose a significant cost to LUL, and that cost is distributed unevenly across stations and across platforms at a station. Transfer stations are perceived very differently by passengers in terms of their overall cost and composition. The case study suggests that a better understanding of transfer behavior and improvements to the transfer experience could significantly benefit public transport systems.     

A network option portfolio management framework for adaptive transportation planning

A real option portfolio management framework is proposed to make use of an adaptive network design problem developed using stochastic dynamic programming methodologies. The framework is extended from Smit’s and Trigeorgis’ option portfolio framework to incorporate network synergies. The adaptive planning framework is defined and tested on a case study with time series origin-destination demand data. Historically, OD time series data is costly to obtain, and there has not been much need for it because most transportation models use a single time-invariant estimate based on deterministic forecasting of demand. Despite the high cost and institutional barriers of obtaining abundant OD time series data, we illustrate how having higher fidelity data along with an adaptive planning framework can result in a number of improved management strategies. An insertion heuristic is adopted to run the lower bound adaptive network design problem for a coarse Iran network with 834 nodes, 1121 links, and 10 years of time series data for 71,795 OD pairs.     

对中等城市公交补贴问题的思考

资金保障是公交优先发展的重要支撑条件,而财政补贴则是公交企业获取资金的重要方式,在以往公交运营管理中,由于缺乏对政策性亏损和经营性亏损的清晰界定.加上未建立完善的公交补贴机制,导致在公交补贴这一问题上较为混乱,一定程度上制约了公交发展.文章以中等城市为研究对象,在明确公共交通属性的基础上,对公交补贴的核心技术问题进行了分析,最后,文章还对中等城市未来面临的复杂公交组成条件下的公交补贴问题进行了初步探讨.     

城市公交场站设施规划

公交场站设施是重要的城市基础设施.本文重点探讨城市公交场站设施规划建设方面的一些问题,包括公交场站发展的规模、场站规划设置标准、场站建设模式等,并提出了相关的意见和建议.     

关于公交线路线形及对位编码的思考

把城市公交线路站点进行线性回归,将其归纳为纵线、横线、左斜线、右斜线和环(含弧)线,并对社区公交提出新的见解.同时采用了分线形按方位区间分别对位编码的方法,对普通的公交线路番号的每个代码赋予特定的含义,使其具有明确的线路走向和方位识别功能.还对“线形布线及对位编码法”在实施中可能出现的问题及应对措施提出了自己的意见.该...
