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。

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.     

快速公交客流量影响因素解释结构模型构建与应用

针对当前交通拥堵、能源紧张、尾气污染等一系列问题,为加快快速公共交通的发展、提高公共交通利用率,本文找出了影响快速公交客流的主要因素,利用系统工程学中的ISM方法,构建了快速公交客流系统解释结构模型,通过分析探讨快速公交客流的主要影响因素,进而明确了各因素间的清晰结构,得到影响快速公交客流量的5级递阶结构;最后找出影响快速公交客流因素的各影响因素.通过影响因素,建立了多元回归模型,从影响程度、影响方向、影响时期分别归类分析.通过分析各层级因素对快速公交客流量的影响,可引导更多居民选择快速公交出行,对缓解交通压力提供了一定方法指导和决策支持.并通过合理分析为快速公交运输服务提出了建议.
