快速道路公交和城市轨道交通关键参数比较及相关问题探讨

对快速道路公交和城市轨道交通系统的规划和建设时间、基建费用和运营成本、票费收支比、补贴和投融资、载客量、速度和灵活性、能源消耗等关键参数进行了分析比较.指出快速道路公交在费用、灵活性和建设周期上具有较大优势,轨道交通系统在载客能力、环境景观和服务水平上更有优势,还可以充分利用地下空间.在层次分析法框架下讨论了发展快速公共交通的决策准则.提出了快速道路公交和轨道交通的两种组合模式:快速道路公交作为轨道交通的补充和延伸,提高公共交通的覆盖率和服务水平;快速道路公交作为轨道交通发展的过渡阶段,先发展快速道路公交,培育客流,待轨道交通建成后再将快速道路公交路权返还给社会车辆.

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.     

Refining light rapid transit typology: a UK perspective

Abstract

Recent developments in the light rapid transit sector have introduced transit modes that are attempting to imitate the performance of others, e.g. buses with tram-like characteristics. The boundaries between existing definitions of what is a bus, tram or train are becoming blurred. For transport studies and practice this requires a review of how we define modes. This is not just a matter of semantics, but has safety and competition regulation implications for system operators. This paper proposes a structure to produce rail- and bus-based transit mode definitions and typology that are appropriate for modern use. A decision tree is used to classify and define the transit modes as guided-bus, trolley-bus, light rail and tram-train and is provided with example systems. The paper provides a robust definitional framework that allows transit system promoters, operators and other interested parties to have a consistent basis of reference when specifying and comparing rapid transit systems.     

常州快速公交系统的实践

作为现代城市可持续发展公共交通新理念的快速公交,正在被中国更多的城市所关注或实施。常州在快速公交的实践中,从建设以人为本、可持续发展和谐常州的基本理念出发,探索把快速公交的要素同常州城市形态和社会经济发展实际进行有机的结合,准确把握“四位”的确立,形成了以中央侧式站台、组合线路等为主要特色的常州快速公交系统。实践表明：常州快速公交系统是结合中国城市实际建设快速公交的成功实践,对于中国其他城市建设快速公交具有借鉴意义。

钢筋混凝土框架结构震后快速鉴定方法

提出一种震后框架结构安全性快速评估的方法.该方法在分析框架结构常见震害的基础上,对地震中构件的破坏程度提出了定量和定性的判断标准;利用模糊数学方法对各类构件进行安全等级评价,形成隶属度判断矩阵;采用层次分析法对各类构件、结构层进行权重评价;依据等级隶属度判断矩阵和各类构件、结构层的权重进行综合分析,得出整体结构的安全性评价.该方法简单易行,层次清晰,鉴定结果较为真实准确.依据该方法,可编制计算软件,使鉴定工作程序化,有效消减鉴定工作量,为震后紧急情况下应急救援政策的制定、救灾措施的实施和开展提供依据.
