Mobile devices and their effect on the sociality on Dutch Intercity trains

ABSTRACT

Travelling by train is an activity that many people engage in on a daily basis, which is rarely performed alone. While trains are locations where many different strangers potentially encounter each other, they are also portrayed as non-social transient places of passenger conflict and disharmony. Especially the rapid rise of mobile devices has changed the way people interact on board. This mobile ethnography – based on observations, travel-diaries and diary-interviews with 16 frequent travellers of Dutch Intercity trains – contributes to earlier studies on passenger sociality by specifically focussing on how social interactions are influenced by these mobile devices. The findings illustrate that using a mobile phone is indeed the most reported on-board activity and direct interactions are limited. Nevertheless, people on the train speak a very subtle non-verbal language that enables them to interact without engaging in extensive direct interactions. Mobile devices are thus not just enabling or constraining but have become inherent parts of socialising. Furthermore, most people do watch out for each other and try not to bother others. Discomforts emerge from different interpretations and compliances of codes of conduct.     

梁柱式支架法在客运专线高墩连续梁施工中的应用

结合广深港客运专线铁路水田特大桥(40+64+40)m高墩连续梁现浇施工,介绍跨路高墩梁柱式支架的设计与施工。该桥梁主墩高31 m,跨越繁忙的石观公路及河流,受地形条件限制,在跨路、跨河处支架采用19.46 m和19.23 m跨径的加强型贝雷梁式支架,贝雷支架上部搭设碗扣支架以满足箱梁变截面要求,下部结构采用钢管支墩、钢筋砼扩大基础,距离河岸边仅3.5 m的扩大基础采用河床堆载反压的方式增强地基承载力,顺利完成了现浇桥梁浇筑,为解决跨路、跨河支架搭设难题积累了经验。     

无偏GM（1,1）幂模型及其应用

针对GM（1,1）幂模型灰微分方程与白化方程无法匹配的缺陷,以灰微分方程的重构为基础,建立无偏GM（1,1）幂模型。该方法使得差分方程的参数与其在微分方程中对应的参数具有更好的一致性。将无偏GM（1,1）幂模型应用到旅游客源预测中,实例应用结果显示无偏GM（1,1）幂模型预测精度高于GM（1,1）模型。

关于铁路客运服务产品质量的量化探讨

铁路是我国经济的大动脉,尤其是客运面向亿万旅客服务,如何对其提供的无形服务产品的质量进行量化考察,是悬而未决的理论和实践问题。本文借鉴现代服务营销理论,结合铁路客运的实际,在对铁路客运服务产品质的规定性进行研究的前提下,着重对其量的测度等问题进行了探索。提出了测度铁路客运服务产品质量的5大属性24个因素(指标)的量化模型,并通过T1/2次客车的问卷调查进行了实征研究,验证了上述量化模型具有科学性,是可行的。

Comparison of bootstrap estimation intervals to forecast arithmetic mean and median air passenger demand

The aim of this paper is to compare passenger (pax) demand between airports based on the arithmetic mean (MPD) and the median pax demand (MePD). A three phases approach is applied. First phase, we use bootstrap procedures to estimate the distribution of the arithmetic MPD and the MePD for each block of routes distance; second phase, we use percentile, standard, bias corrected, and bias corrected accelerated methods to calculate bootstrap confidence bands for the MPD and the MePD; and third phase, we implement Monte Carlo (MC) experiments to analyse the finite sample performance of the applied bootstrap. Our results conclude that it is more meaningful to use the estimation of MePD rather than the estimation of MPD in the air transport industry. By carrying out MC experiments, we demonstrate that the bootstrap methods produce coverages close to the nominal for the MPD and the MePD.

Risk‐Based Decision Support Tools: Protecting Rail‐Centered Transit Corridors from Cascading Effects

We consider the value of decision support tools for passenger rail system managers. First, we call for models that follow events along main rail lines and then into the surrounding environment where they can cascade onto connected light rail, bus, auto, truck, and other transport modes. Second, we suggest that both probabilistic risk assessment (PRA‐based) and agent‐based models have a role to play at different scales of analysis and for different kinds of risks. Third, we argue that economic impact tools need more systematic evaluation. Fourth, we note that developers of decision support tools face a challenge of balancing their desire for theoretical elegance and the tendency to focus only on high consequence events against decisionmakers’ mistrust of complex tools that they and their staff cannot manage and incorporate into their routine operations, as well as the high costs of developing, updating, and applying decision support tools to transport systems undergoing budget cuts and worker and service reductions.
