为轨道交通运营安全加码

<正>7月27日,北京地铁机场线一列车在行驶途中,列车车厢顶部突然起火冒烟,随后机场线中断运营;7月28日上海地铁1号线早高峰期间,供电系统突发故障,致使大量乘客滞留。尽管采取了相应的应急措施,故障仍对城市交通运输造成了诸多不便,也将轨道交通运营安全提上了公众的关注热点。8月11日,交通运输部办公厅发布《关于做好〈国家城市轨道交通运营突发事件应急预案〉贯彻落实工作的     

高峰时段铁路车站晚点时长分布规律

基于运行实绩对高铁车站在早晚高峰时间段下的晚点时长分布规律进行研究，为行车人员提供行车指导，辅助行车人员充分估计晚点时长特征及预测晚点发展态势，更好地进行调度决策。首先描述高速铁路沪昆线上的运行实绩数据，并统计出早晚高峰时段下的车站晚点时长数据。然后，结合统计模型构建车站在早晚高峰时间段下的晚点时长分布模型，并比选确定出最优的晚点时长分布模型。最后，对车站在早晚高峰时段下的晚点时长分布特征进行归纳总结，相关研究结论能为列车晚点传播机理以及智能高铁调度指挥系统提供基础支撑。     

行车间隔对高速铁路运行图可靠性影响仿真研究

高速铁路列车高峰时段行车间隔时间是决定列车运行图抗干扰能力和运输能力的主要因素。以晚点列车数、晚点总时间、冗余时间利用率和正点率作为评价指标,运用高速铁路调度指挥仿真系统研究列车行车间隔时间对运行图可靠性的影响。结果表明:在无系统干扰下,列车运行图保持高可靠性;在5min和10min行车干扰下,采用5min的行车间隔可保证运行图的可靠性;行车间隔5min实验方案受干扰大于10min时,晚点纵向传播程度大幅增大,为保证运行图可靠性前提下,宜采取8min行车间隔运行图。

新建地铁隧道近距离下穿运营地铁线路施工及安全管控北大核心CSCD

新建青岛地铁8号线青岛北站—沧口站区间近距离下穿既有运营地铁3号线,初期支护距3号线底板结构仅0.4 m,在不影响既有地铁3号线正常运营的前提下,施工难度极大。通过构建三维有限元模型,模拟新建线路下穿施工全过程,制定针对性措施:采用非爆破机械开挖减小震动;加强超前支护和及时支护封闭成环,控制沉降;自动化监测快速反馈3号线结构变形信息以指导现场施工。通过现场技术手段和安全管控手段,下穿施工期间3号线隧道结构最大沉降仅2.11 mm,道床最大沉降仅1.55 mm,满足沉降控制要求,施工期间未对地铁3号线的安全运营产生影响。相关工程经验可为今后小净距、小角度、长距离下穿既有运营地铁工程的设计、施工提供借鉴。

春运紧张更需消解高铁风险

春运紧张穿梭如织，京沪高铁发生故障，导致数趟列车晚点，幸无旅客生命安全之虞。如许晚点之扰与安全之忧，或能在归心似箭的情愫与春节团圆的气氛氤氲中被稀释和冲淡。不能不说，此次京沪高铁故障，即是风险露头的一个表征。其所带来的危害虽很微弱，但在反思和检讨的深刻方面却不能轻易滑过。铁道部称，故障原因是“受雨雾天气影响，京沪高铁车顶高压设备绝缘值降低，

The potential of mobility as a service bundles as a mobility management tool

Transportation - The Mobility as a Service (MaaS) concept has recently taken the transport industry by storm. However, as applications and research on it are limited, there is still little evidence...     

Motility as a policy objective

Western literature abounds with powerful imagery of mobility and travel, extolling the richness of experience and learning that can only happen along the way. The more common policy and research contexts consider travel and mobility as an important means to an end, valued relative to the destination activity. This review builds on the research that considers on-the-way benefits in order to expand this perspective as a part of transport studies. The question posed is if there is a place to evaluate mobility as a life-enhancing activity in its own right, directly contributing to the capacity for autonomy and freedom of choice that are central elements of personal well-being. Motility or mobility capital, defined as the capacity for mobility, offers a theoretical context for this purpose. The literature has adopted motility for its ability to broaden the understanding of mobility choices, by structuring a role for material, human, social and cultural capital as contributing to an individual’s capacity for mobility. The context of individual capital implies that motility holds value not only as an input to mobility choices, but also through its exchange value with other forms of capital, thereby promoting broader contexts for human flourishing. Therefore, motility has value as a policy objective for its contribution to individual well-being and this article further argues that it is through mobility experiences that this type of capital can be advanced.     

Consumers as participants in transportation planning

Legal requirements for public participation in transportation planning increase the opportunity for transportation consumers to influence the design of systems they will use. However, the implementation of these requirements may also increase the possibility that system design will be dominated by the opinions of outspoken groups. This study postulates that public participation is biased, and seeks to test this proposition using data from an Oregon survey consisting of approximately 2,400 respondents. Using Automatic Interaction Detector and cross tabulation analyses, different participation rates were uncovered for groups identified by demographic, attitudinal and behavioral variables.The authors thank the Oregon Department of Transportation for making the original data for the study available.

Transportania as gulliver might have seen it

It is an honour to be asked to speak at this, the Silver Jubilee of the International Symposia in 1984, in the presence of a number who, unlike myself, were present at the first symposium at the General Motors Research Laboratories in 1959 - Gordon Newell, Martin Beckmann and, foremost of all, Robert Herman, whose work is to be recognized next week by the award of an Honorary Degree at the University of Karlsruhe. Because it is such an honour to be asked, I had no hesitation in accepting Professor Volmuller's invitation, several months ago - to address you with a causerie on a subject of my choice.     

Air traffic control complexity as workload driver

This paper describes an investigation into ATC complexity as a contributory factor in changes of controllers’ workload. ATC complexity, together with equipment interface and procedural demands comprise the task demands on the controller; subsequent controller activities are mediated by performance shaping factors to create workload. In order to establish a link between ATC complexity and a controller’s subjective workload, complexity factors are identified and subsequently related to workload indicators. The studied data comes from a real-time simulation using Controller-Pilot Data-Link Communication (CPDLC) technology, recently completed at EUROCONTROL CRDS in Budapest.
