基于CML的多重边复杂公交线路网络相继故障研究

为给城市公交系统的规划、建设和管理优化提供决策依据,在现有公交网络模型的基础 上,以常规公交线路为网络的节点,公交线路间的若干个公共停靠站点为连边,建立了基于耦合 映像格子的多重边复杂公交线路网络模型,基于该模型研究了多重边复杂公交线路网络的相继故 障问题。通过Matlab 数值仿真技术,详细分析了扰动幅值和耦合强度对网络相继故障的影响。研 究结果表明：蓄意攻击多重边复杂公交线路网络中度最大的节点最容易造成网络全局故障;另 外,耦合强度和扰动幅值越大,多重边复杂公交线路网络越容易发生相继故障。     

基于集成场的冷链突发事件防范与应对策略研究

以冷链突发事件为例,依据集成场理论,从冷链系统顶层的集成体、基核和联接键等关键要素出发,分析了当前冷链突发事件中存在的问题.对冷链突发事件形成的因素和事件特点进行了归纳,针对不同的物流集成体服务模式的优劣以及如何更好地提高冷链物流运作的效率进行了合理的分析.结果表明:公共型基核是冷链系统今后一段时间的重点发展项目;基核微观运作直接影响到冷链作业质量和系统安全,需要加强公共型基核现场运作的综合信息系统等联接键构建,提升全系统的资源整合能力和可视化监管能力,提升基核对冷链突发事件的防范与应对能力.同时针对基本服务模式提出了冷链突发事件防范的若干建议.

铁路突发公共卫生事件预警系统初探

铁路突发公共卫生事件,一类是由地方性公共卫生事件的冲击而引起,另一类则是由铁路内部公共卫生管理不良所致。为能尽早识别第一类公共卫生事件;识别铁路公共卫生管理可能出现失误的条件,尽早采取有效的预控措施,防止第二类事件的发生,降低第一类事件的扩散面,减少损失,建设具有预警、纠偏、免疫功能的铁路突发公共卫生事件预警系统已是当务之急。     

Transantiago: A tale of two cities

The Chilean government decided to modernize Santiago's entire public transport system, integrating the underground and the private bus networks based on a structure of trunk and feeder services, and a fare-payment by touchless smart card. The new, integrated transit system, known as Transantiago, very soon ran into serious problems that alienated much of its user base and significantly lowered the government's approval ratings. This paper recounts how Transantiago was planned and designed and then discusses its evolution after implementation. It concludes with suggestions for the Transantiago authorities and lessons to be learned from this traumatic process.

Cooperation in transit delivery in West German metropolitan areas

West Germany is densely populated, averaging 245 inhabitants/km², but varying widely between urban agglomerations and rural areas. Transport volume has increased by 40% since 1970, with virtually all growth due to private automobiles. Since 1981 public transit has been suffering from decreasing demand.A 1964 Expert's Report to the German federal government was the stimulus for initiating an effective funding mechanism for new public transit construction. In 1965 Germany's first federated transit authority was founded for the region of Hamburg.Principal among the goals of any cooperative agreement among transit companies are improvements for the passengers and improvement of revenues for the companies. To attain these ends, two distinct forms of transit aggrements have been developed in Germany: transit cooperative (Verkehrsgemeinschaft) and transit federation (Verkehrsverbund). The former is more suitable for smaller to medium-sized towns, while the latter is more suitable for larger cities. The two types are described in this article.German transit federations during the 1970s succeeded in significantly increasing ridership, while during the 1980s patronage has either remained steady or has declined. Yet transit federations showed much better perfomance than did public transit in general. In terms of costs and revenues, no public transit organization in Germany is able to break even; deficits vary between 42% and 55%. The author concludes, however, that hidden subsidies for automobile traffic are far higher, because of environmental damage and the high social cost of traffic accidents.     

Spatial variations in attitudes toward expanded public transit service

Although recent budgetary considerations by the Federal govenment do not portend well for urban public transit, some transit systems are considering expansion into less densely-settled areas further from the Central Business District. Of some concern to planners has been their belief that suburban and rural dwellers may be much less inclined than urban dwellers to support expansion of transit service. This paper presents an analysis of a random-digit dialing/mail-out, mail-back survey conducted in Washtenaw County, Michigan which was designed specifically to examine differences in attitudes between urban and rural residents. Six mutually-exclusive spatial strata were established based upon population density. This paper tests for expected spatial differences in socioeconomic and demographic variables and then examines spatial variations in attitudes toward public transportation. The major conclusion is that the expected spatial variations in attitudes about transit service provision between the spatial strata do not arise. Most of the significant differences found are with respect to questions which relate to where transit is provided. Residents in rural (urban) areas support more strongly the provision of services to rural (urban) areas. Many residents, however, will support transit service that may not benefit them directly.
