基于粗糙集理论的BRT运营服务水平可拓评价*

BRT运营服务水平的分析与评价对城市快速公共交通系统的规划与管理起着重要的指导作用。传统的评价方法其权重确定虽然简单,但往往受主观因素影响,鉴于此,采用粗糙集理论对指标进行约简得到各个指标重要性和较为客观的权重,结合物元分析法建立指标性能参数的评定模型,利用关联函数进行可拓分析,对快速公交运营服务水平进行可拓综合评价。通过实际算例来说明该方法的合理性和有效性。研究结果表明：基于粗糙集的 BRT运营服务水平可拓综合评价方法,能够对快速公交系统服务水平进行全面正确的综合评价。     

基于IC卡数据的公交线网评价

公共交通是促进城市可持续发展和实现低碳交通的有效措施之一．对公交线网的评价也越来越受到管理和研究人员的重视。为了利用IntegrateCircuit（IC）卡数据获得大量的出行信息,对公交线网的服务水平做出合理的评价．提出了3个指标：流量差异、供需差异、时间差异,用于评价乘客需求和公交线网布局的空间匹配程度。最后,以南宁市为例,将上下班高峰时段的IC卡数据在TransCAD中进行了验证,证明了该方法的科学性和实用性,从而提供了一种从乘客出发的．更加直接的、合理的公交线网评价方法。     

支撑城镇化发展的市郊轨道交通规划问题探讨

当前新型城镇化发展战略已成为我国社会经济实现持续健康发展的重要途径之一,而交通运输系统作为城镇化发展的重要支撑与其存在密切的双向互动关系.鉴于此,基于新型城镇化发展战略视角,对市郊轨道交通的建设意义、功能定位及特征进行了重新的审视与深入的分析,在此基础上对包括线路布设、站点规划设计以及系统制式等方面的市郊轨道交通规划相关问题进行了较深入的探讨.     

城市轨道接驳公交线网优化调整研究

根据国内外城市轨道交通发展经验．分析并总结了轨道交通发展的三个阶段,以及各阶段轨道与常规公交在城市客运体系中的功能定位．明确了城市轨道交通与常规公交存在的接驳性和竞争性关系,并据此针对常规公交线路具体情况,分别提出了城市轨道接驳性线路和竞争性线路规划模式。最后以深圳市轨道接驳线网优化调整为例,对上述理论方法进行了实例阐述．并对实施效果进行了验证与分析。     

Rail vehicles,environment, safety and security

This paper starts with a discussion on typical vehicles. The concepts and the usual practice for rail wagon design, both freight and passengers are presented. A discussion on rail and the environment comes next followed by Truck-Trains. Accident theories, metaphors and investigation methods are widely discussed; Hazard – Barrier – Target Model, Swiss Cheese Model, Bow-Tie Model, Fault Tree Analysis and Event Tree Analysis are explained. This paper concludes with a technical discussion on safety and security of rail vehicles, standards for safety and measures against terrorist attacks.     

Rail infrastructure,ITS and access charges

This paper presents an overview of the principles and technologies relating to railway infrastructure. Specifically this paper includes rail–wheel contact, inspection and maintenance of rail. Intelligent transport systems (ITS) and their applications for the purposes of the railway transport in Europe are discussed. The potential, levels of development, technological and operational characteristics of the European Railway Traffic Management System (ERTMS) are presented. Finally, a discussion on methodologies, principles and current practices for access charging in Europe is provided.     

Engaging the paratransit sector in Cape Town on public transport reform: Progress,process and risks

The South African government in 2006 initiated an urban public transport reform programme reliant on the introduction of new bus rapid transit (BRT) systems. Affected paratransit operators can opt to be incorporated in these systems by forming new operating companies, but must withdraw their existing services from proposed routes. Cape Town's first phase of BRT operations came online in 2011, and operator engagement has focussed on this phase. The attitudes within this city's paratransit sector in relation to future phases, and to the broader reform policy, remain largely untested. In view of this sector's past resistance to government-led proposals, and the current phase avoiding areas with the highest concentrations of operators, the current engagement process's outcomes may not be adequate indicators of future prospects.     

Incentives in Bus Concession Contracts: A Review of Several Experiences in Latin America

Abstract

This paper reviews the incentive structure of concession contracts in several Latin American transit reforms. It also presents a conceptual analysis of the optimal design of concession contracts. The conceptual discussion and case studies reviewed indicate that payment to operators should be linked to operational variables and that some demand risk should optimally be transferred to operators. Performance standards linked to fines and penalties are not sufficient to guarantee good quality of service, particularly in citywide reforms and where institutional capacity ― in terms of size, experience and expertise of staff ― is lacking and regulatory processes are slow, bureaucratic and cumbersome. This review may be useful for policy-makers designing transit reforms in other countries. The policy lessons of the paper are particularly relevant to cities in the developing world but they are also important for reforms in other countries.

构建了TOD模式下城市轨道交通与土地利用的协调关系评价指标体系,通过修正的数据包络分析（DEA）方法对城市轨道交通与沿线土地利用的协调关系进行了评价与排序.将不同输入、输出指标进行均值化处理,通过分析不同指标间的松弛变量和剩余变量,得出各个指标对城市轨道交通与土地利用协调发展的影响程度.根据DEA有效前沿面投影理论,提出DEA无效决策单元实现协调发展时应达到的标准,为无效决策单元的改进提供了参考.以美国阿勒格尼为案例进行分析,结果表明：该评价方法分析结果与实际情况一致,能够较好地评价城市轨道交通与土地利用的协调关系.
