    公共交通是性暴力和性骚扰的热点。通过对在公共交通工具上遭受性暴力和骚扰的妇女和性别多样化人士的41次采访,我们发现,妇女和性别多样化的人从事广泛的“安全工作,“比如改变他们的行为,制定战略,和规划。安全工作需要大量的时间和精力,经常让参与者感到压力。然而,与会者主张改变公共交通,以减少他们为保持安全而做的工作。我们认为重大变化,包括初级预防基于性别的暴力,需要减少他们的安全工作。
    Public transport is a known hotspot for sexual violence and harassment. Through 41 interviews with women and gender-diverse people who have experienced sexual violence and harassment on public transport, we found that women and gender-diverse people engage in extensive \"safety work,\" such as changing their behavior, strategizing, and planning. Safety work takes considerable time and effort, often leaving participants feeling stressed. However, participants advocated for changes to public transport to reduce the work they do to stay safe. We argue that significant changes, including primary prevention of gender-based violence, are needed to reduce their safety work.

    背景:关于交通工具使用和死亡率的大多数证据都集中在通勤工作上。这项研究旨在通过评估老年人的公共交通使用与死亡率之间的关系来填补这一空白。
    方法:数据来自参与英国老龄化纵向研究(ELSA)的10,186名50岁或50岁以上的个体的队列,调查数据与16年(2002-2018年)的死亡率记录相关。我们评估了从“每天或几乎每天”到“从不”的公共交通使用和使用频率的二元度量。Cox比例风险回归模型用于估计公共交通使用与死亡率之间关联的95%置信区间(CI)的风险比(HR)。分析调整了一系列协变量,包括社会人口因素,慢性疾病,以及日常生活活动中自我报告的问题。
    结果:总体而言,3371名参与者(33.1%)在研究期间死亡。公共交通用户(21.3%)的死亡率低于非用户(64.2%)。调整后的分析发现,使用者的死亡率比非使用者低34%(HR0.66(95%CI0.61;0.71))。调整后的分析显示,公共交通使用频率之间的关联大小相似,每天或几乎每天使用公共交通工具的人的死亡率比从未使用过的人低41%(HR0.59(0.49;0.71))。有和没有长期疾病的人之间的协会相似。
    结论:老年人使用公共交通工具与较低的死亡率有关。减少公共交通服务的提供可能不利于运输和人口健康。
    BACKGROUND: Most evidence on transport use and mortality has focused on the commute to work. This study aims to fill a gap by assessing relationships between public transport use and mortality among older adults.
    METHODS: Data come from a cohort of 10,186 individuals aged 50 or older who participated in the English Longitudinal Study of Ageing (ELSA), with survey data linked to mortality records over 16 years (2002-2018). We assessed a binary measure of public transport use and frequency of use from \'every day or nearly every day\' to \'never\'. Cox proportional-hazards regression models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for associations between public transport use and mortality. Analyses were adjusted for a range of covariates including socio-demographic factors, chronic disease, and self-reported problems with daily living activities.
    RESULTS: Overall, 3371 participants (33.1%) died within the study period. Mortality was lower among public transport users (21.3%) compared with non-users (64.2%). Adjusted analyses found that users had 34% lower mortality than non-users (HR 0.66 (95% CI 0.61;0.71)). Adjusted analyses showed similar association sizes across frequencies of public transport use, with those using public transport every day or nearly every day having 41% lower mortality than never users (HR 0.59 (0.49;0.71)). Associations were similar among those with and without a longstanding illness.
    CONCLUSIONS: The use of public transport among older adults is linked to lower levels of mortality. Reductions in provision of public transport services could be detrimental to both transportation and population health.

    服务失败一定会发生,但是以前学者们总是对此不满。本研究借助预期不确认理论(EDT)模型,调查了导致再次旅行意图的旅行决策中的不满意因素。此外,投诉行为在不满意和再次旅行意向之间的关系中起中介作用。对于调查结果,通过采用终身价值(LTV)方法的离线调查收集了434份实时响应。进行了Kaiser-Meyer-Olkin(KMO)和Bartlett\的测试,以逐个测试变量的球形度。此外,隐含结构方程模型(SEM)来检验测量模型和结构模型。所有假设都支持并接受了提出的研究问题。调查结果表明,不满因素,与他们的交互术语(基于交易和基于经验),帮助研究旅行和旅游文学中的变量不满及其多方面的概念。此外,投诉行为被认为是不满和再次旅行意图之间关系的关键中介因素,暗示通勤者对不满的反应,包括投诉,塑造他们未来的再旅行意图。这项研究的理论意义是巨大的,因为它提高了我们对公共交通旅行和旅游背景下通勤行为的理解。实际上,这些发现为公共交通当局和服务提供商提供了可行的见解。了解影响再旅行意向的具体不满意因素,可以有针对性地进行干预,以提高服务质量和客户体验。认识到有效的投诉管理系统的重要性可以帮助组织更好地解决客户的不满,并减轻不满对重游意向的负面影响。
    Service failure is bound to happen, but dissatisfaction has always been undermined by scholars previously. The present study investigates dissatisfaction factors in travel decision-making leading towards re-travel intention with the help of the expectancy disconfirmation theory (EDT) model. Moreover, complaint behavior mediates the relationship between dissatisfaction and re-travel intention concerning the factors involved in it. For the findings, 434 real-time responses were collected through an offline survey following the lifetime value (LTV) approach. Kaiser-Meyer-Olkin (KMO) and Bartlett\'s tests were conducted to test the sphericity of the variables one by one. Furthermore, structural equation modeling (SEM) was implied to test the measurement and structural models. All the hypotheses supported and accepted the proposed research questions. The findings reveal that the dissatisfaction factors, with their interaction terms (transaction-based and experience-based), help study the variable dissatisfaction and its multifaceted concept in travel and tourism literature. Moreover, complaint behavior is identified as a key mediating factor in the relationship between dissatisfaction and re-travel intention, suggesting that commuters\' response to dissatisfaction, including complaints, shapes their future re-travel intentions. The theoretical implications of the study are substantial, as it advances our understanding of commuter behavior in the context of public transport travel and tourism. Practically, the findings offer actionable insights for public transport authorities and service providers. Understanding the specific dissatisfaction factors influencing re-travel intention allows for targeted interventions to improve service quality and customer experience. Recognizing the importance of effective complaint management systems can help organizations better address customer grievances and mitigate the negative effects of dissatisfaction on re-travel intention.

    目的:已经报道了积极通勤的健康益处。然而,很少有研究使用客观方法评估通勤模式。这项研究阐明了日本工人客观测量的通勤方式的变化与体重之间的关系。
    方法:这项纵向研究使用了一家在日本各县设有分支机构的公司的年度健康检查和人员记录数据。2018年和2019年的数据作为基线和后续数据,分别。使用人员记录中包含的通勤模式代码评估通勤模式,并将其分为三种类型:步行,公共交通,汽车或摩托车。根据2018年和2019年的通勤方式,参与者被分为九类。在健康检查期间客观测量体重。计算了9个类别的1年体重变化,并使用协方差分析和协变量调整进行评估。
    结果:分析包括6,551名工人(男性:86.8%;平均年龄:42.8岁)。总的来说,体重有增加的趋势(+0.40公斤/年)。切换到更积极通勤的参与者,例如从汽车或摩托车到步行(-0.13公斤/年),从汽车或摩托车到公共交通工具(+0.10公斤/年),从公共交通到步行(-0.07公斤/年),表现出少量的体重增加或损失。即使在调整后也观察到类似的趋势。
    结论:改变到更积极的通勤模式可能会防止工人体重增加。
    OBJECTIVE: The health benefits of active commuting have been reported. However, few studies have assessed commuting modes using objective methods. This study clarified the association between changes in objectively measured commuting modes and body weight among Japanese workers.
    METHODS: This longitudinal study used data from the annual health examinations and personnel records of a company with branches in all prefectures of Japan. Data from 2018 and 2019 were used as the baseline and follow-up data, respectively. The commuting mode was assessed using the commuting mode code included in the personnel records and classified into 3 types: walking, public transport, and car or motorcycle. The participants were classified into 9 categories based on the combination of their commuting modes in 2018 and 2019. Body weight was measured objectively during health examinations. The 1-year changes in body weight were calculated for the 9 categories and assessed using an analysis of covariance with adjustments for covariates.
    RESULTS: The analysis included 6551 workers (men: 86.8%; mean age: 42.8 years). Overall, body weights tended to increase (+0.40 kg/y). The participants who switched to more active commuting, such as from car or motorcycle to walking (-0.13 kg/y), from car or motorcycle to public transport (+0.10 kg/y), and from public transport to walking (-0.07 kg/y), exhibited small weight gains or losses. A similar trend was observed even after adjustment.
    CONCLUSIONS: Changing to a more active commuting mode may prevent weight gain among workers.

    公共交通在满足交通需求方面发挥着关键作用,特别是在人口稠密的地区。新冠肺炎疫情凸显了公共卫生措施的重要性,包括需要防止病毒通过公共交通工具传播。使用计算流体动力学(CFD)模型和蒙特卡罗模拟研究了病毒在客船上的传播。一个特别的焦点是孟加拉国的背景,南亚一个人口众多的海洋国家,其中很大一部分人口利用客船来满足运输需求。在这方面,使用湍流模型,模拟气流模式并确定污染区域。正在调查的参数是航行持续时间,机上乘客人数,社会距离,手术口罩的效果,和其他人。这项研究表明,SARS-CoV-2感染在公共交通上的传播率,如客船,不一定与航程持续时间或船上乘客数量成正比。该模型有可能应用于各种其他运输方式,包括公共巴士和飞机。实施该模型可能有助于有效监测和解决公共交通网络中的潜在健康风险。
    Public transportation plays a critical role in meeting transportation demands, particularly in densely populated areas. The COVID-19 pandemic has highlighted the importance of public health measures, including the need to prevent the spread of the virus through public transport. The spreading of the virus on a passenger ship is studied using the Computational Fluid Dynamic (CFD) model and Monte Carlo simulation. A particular focus was the context of Bangladesh, a populous maritime nation in South Asia, where a significant proportion of the population utilizes passenger ships to meet transportation demands. In this regard, a turbulence model is used, which simulates the airflow pattern and determines the contamination zone. Parameters under investigation are voyage duration, number of passengers on board, social distance, the effect of surgical masks, and others. This study shows that the transmission rate of SARS-CoV-2 infection on public transport, such as passenger ships, is not necessarily directly proportional to voyage duration or the number of passengers onboard. This model has the potential to be applied in various other modes of transportation, including public buses and airplanes. Implementing this model may help to monitor and address potential health risks effectively in the public transport networks.

    公共交通优先系统,如快速公交(BRT)和高服务水平公交车(BHLS)是低收入和中等收入城市出行的顶级解决方案。科学上一致认为,这些系统的安全性能水平取决于它们的功能,操作,和基础设施特点。然而,需要有更多的证据来证明公共汽车走廊的不同特征如何影响安全。本文旨在通过构建多元负二项模型来比较主干道上的碰撞风险,从而揭示这一领域。BRT,和波哥大的BHLS走廊,哥伦比亚。分析的基础设施包括712.1公里的主干道和标准巴士服务,194.1公里的BRT网络,和135.6公里的BHLS网络。该研究考虑了2015年至2018年的撞车事故-死亡人数,受伤,仅财产损失和30个运营和基础设施变量分为六类-暴露,道路设计,基础设施,公共交通工具,和土地使用。采用多标准过程进行模型选择,包括基于[i]Akaike信息标准的结构和预测能力,[ii]K折交叉验证,和[iii]模型简约。相关发现表明,就观察到的和预期的事故率及其与暴露程度的关系-高峰小时平均年交通量的对数(LOG_AAPHT)和摩托车百分比而言,汽车,公共汽车,和卡车——最大的死亡风险,受伤,和财产损失发生在BHLS网络中。BRT网络在较不严重的碰撞中提供较低的碰撞率,同时增加伤害和死亡人数。在比较BHLS网络和主干道标准设计时,BHLS基础设施,尽管移动性越来越大,在三个分析的网络中提供最低的安全性能。研究的各个因素也可能有助于设计与信号交叉口密度和曲率相关的更安全的道路。这些发现支持了波哥大背景下的独特特征和交通动态,可以为发展中国家其他高密度城市地区的相应当局提供信息和指导。
    Public transport priority systems such as Bus Rapid Transit (BRT) and Buses with High Level of Service (BHLS) are top-rated solutions to mobility in low-income and middle-income cities. There is scientific agreement that the safety performance level of these systems depends on their functional, operational, and infrastructure characteristics. However, there needs to be more evidence on how the different characteristics of bus corridors might influence safety. This paper aims to shed some light on this area by structuring a multivariate negative binomial model comparing crash risk on arterial roads, BRT, and BHLS corridors in Bogotá, Colombia. The analyzed infrastructure includes 712.1 km of arterial roads with standard bus service, 194.1 km of BRT network, and 135.6 km of BHLS network. The study considered crashes from 2015 to 2018 -fatalities, injuries, and property damage only- and 30 operational and infrastructure variables grouped into six classes -exposure, road design, infrastructure, public means of transport, and land use. A multicriteria process was applied for model selection, including the structure and predictive power based on [i] Akaike information criteria, [ii] K-fold cross-validation, and [iii] model parsimony. Relevant findings suggest that in terms of observed and expected accident rates and their relationship with the magnitude of exposure -logarithm of average annual traffic volumes at the peak hour (LOG_AAPHT) and the percentage of motorcycles, cars, buses, and trucks- the greatest risk of fatalities, injuries, and property damage occurs in the BHLS network. BRT network provides lower crash rates in less severe collisions while increasing injuries and fatalities. When comparing the BHLS network and the standard design of arterial roads, BHLS infrastructure, despite increasing mobility benefits, provides the lowest safety performance among the three analyzed networks. Individual factors of the study could also contribute to designing safer roads related to signalized intersection density and curvature. These findings support the unique characteristics and traffic dynamics present in the context of Bogotá that could inform and guide decisions of corresponding authorities in other highly dense urban areas from developing countries.

    近年来,公共交通服务质量研究的重要性显著提高,这是了解和分析乘客偏好的关键。然而,不同的方法被用来探索用户的偏好,这些主要仅应用对移动性的属性和替代方案的主观评分。在本文中,我们设计了一个具体的公交方式选择模型,该模型能够将主观评分与距离或时间等客观指标的评分相结合。由于这个目的,我们结合了超越偏好排名组织的方法进行富集评估(PROMETHEE)作为一种方法来评估乘客对有形和无形标准的偏好与模糊理论,和交互式辅助图形分析(GAIA)平面,以可视化属性之间的交互,并通过灵敏度分析来测试结果的稳健性。本文的贡献是构建的综合方法,该方法比众所周知的模型主观性低,但也保持了个体评估者表达偏好的自由。此外,模式选择分析的另一个重要问题是群体考虑,在新的方法中,不仅考虑了群体偏好的平均值,而且考虑了群体偏好的范围,也对其进行了改进。公共调查的共同特征,用模糊方法解决外行人模式可能的模糊响应,以降低不确定评分的风险。所提出的模型是模糊推理系统的重要基础,可以在不断变化的环境中为乘客提供模式选择。通过布达佩斯市的真实案例研究证明了新方法的效率,所获得的结果支持了地下模式服务质量,并强调了其对公民有利于公共交通的行为的影响。
    The importance of public transportation service quality research is significantly increasing in recent years, it is the key to understanding and analyzing passengers\' preferences. Different approaches are utilized to explore users\' preferences however, dominantly these apply merely subjective scoring of the attributes and alternatives of the mobility. In this paper, we design a specific model for public transportation mode choice which is capable of integrating subjective scoring with scoring by objective measures such as distance or time. Owing to this purpose, we combine the outranking Preference Ranking Organization METHod for Enrichment Evaluation (PROMETHEE) as a method to evaluate passengers\' preferences for tangible and intangible criteria with the fuzzy theory, and the Graphical Analysis for Interactive Aid (GAIA) plane to visualize the interactions between attributes as well as to test the robustness of the results via sensitivity analysis. The contribution of this paper is the constructed integrative method that is less subjective than the well-known models but also keeps the freedom of individual evaluators in expressing their preferences. Moreover, another significant issue of mode choice analysis is the group consideration, which is also refined in the new methodology by taking into account not only the mean of group preferences but also their range. A common characteristic of public surveys, the possible vague responses of the layman pattern is solved with the fuzzy approach to reduce the risk of uncertain scoring. The proposed model acts as a great base for the fuzzy inference system that can facilitate mode choice for passengers within a changing environment. The efficiency of the new methodology is demonstrated through a real-world case study of Budapest city, the obtained results are supporting underground mode service quality and highlighting its impact on citizens\' behavior in favor of public transport.

    随着人口密度和环境意识的提高,公共交通已成为城市生存的重要组成部分。目前产生了大量的数据,允许更强大的方法来通过收集智能卡的使用来了解旅行行为。然而,公共交通数据集存在数据完整性问题;由于获取过程不完善或报告不足,登机站信息可能会丢失。本研究引入了一种有监督的机器学习方法,使用GTFS时间表基于顺序分类来估算失踪的登机站,智能卡,和地理空间数据集。一个新的指标,帕累托准确度,建议评估类具有序数性质的算法。结果基于比尔舍瓦市的案例研究,以色列,由一个月的智能卡数据组成。我们表明,我们提出的方法对不规则旅行者是鲁棒的,并且在不需要挖掘任何其他数据集的情况下,显着优于众所周知的估算方法。使用迁移学习从另一个以色列城市进行的数据验证表明,所提出的模型是通用且无上下文的。进一步讨论了交通规划和出行行为研究的意义。
    Public transport has become an essential part of urban existence with increased population densities and environmental awareness. Large quantities of data are currently generated, allowing for more robust methods to understand travel behavior by harvesting smart card usage. However, public transport datasets suffer from data integrity problems; boarding stop information may be missing due to imperfect acquirement processes or inadequate reporting. This study introduces a supervised machine learning method to impute missing boarding stops based on ordinal classification using GTFS timetable, smart card, and geospatial datasets. A new metric, Pareto Accuracy, is suggested to evaluate algorithms where classes have an ordinal nature. The results are based on a case study in the city of Beer Sheva, Israel, consisting of one month of smart card data. We show that our proposed method is robust to irregular travelers and significantly outperforms well-known imputation methods without the need to mine any additional datasets. The data validation from another Israeli city using transfer learning shows the presented model is general and context-free. The implications for transportation planning and travel behavior research are further discussed.

    本文着重于对公共交通(PT)和私家车(PV)用户对服务质量的看法进行比较分析。为了检测PT属性的关键组成部分,应用了一种新的混合方法,将重要性-性能分析和重要性-性能图分析相结合。所提出的混合方法比文献中的现有方法更简单且更集成。样本包括一个在线面板,以及在布达佩斯大流行期间调查的1028份PV和PT用户问卷。应用方法的结果表明,在不同的群体中,服务时间,接近,在COVID-19年代,频率属性很重要,表现良好。另一方面,温度和清洁度因素不是PV和PT用户总体满意度的重要预测因素。获得的结果可供地方政府和当局使用,他们试图在大流行浪潮中的行动限制期间确定提高PT服务质量的领域。
    The current paper focuses on a comparative analysis of both public transport (PT) and private vehicle (PV) users\' perceptions on the quality of the service. To detect the key components of PT attributes a new hybrid methodology is applied, combining the importance-performance analysis and the importance-performance map analysis. The proposed hybrid approach is simpler and more integrated than the existing methods in the literature. The sample comprises an online panel and a total of 1028 questionnaires for PV and PT users surveyed during the pandemic period in Budapest. The results of the applied methods show that among the different groups, the service hour, the proximity, and the frequency attributes are important and performed well in the years of COVID-19. On the other hand, the temperature and the cleanliness factors are not significant predictors of the PV and PT users\' general satisfaction. The obtained results can be used by local governments and authorities, who seek to identify areas to enhance the service quality of PT during movement restrictions in a pandemic wave.

    我们为奥地利的全国性“移动服务保证”(MSG)提供草图。这种方法遵循了一种新的范式,转向以汽车为中心的交通政策和规划,转向广泛提供公共交通。该方法得到了满足需求的运输服务的补充,并支持车辆共享以及主动移动。这种组合应作为使用私家车的有效替代选择。
    本研究的目的是在奥地利背景下以及可能的设计场景中制定全国性MSG的切实定义。
    我们采取了多维方法,利用文献综述研究现有的流动性保障概念,分析当前交通行为和公共交通供应的二级数据,并举办利益相关者研讨会。
    我们定义了设想全国性MSG的可能方案,包括到公共交通站点的最大距离和最小频率的不同程度。我们讨论了味精在空间方面的局限性,时间和模态覆盖,以及如何将这种保证嵌入现有的法律体系中。
    我们得出的结论是,全国性的MSG可能是可持续运输政策的重要组成部分,应将其嵌入更广泛的基础设施和服务设计以及需求管理战略中。
    UNASSIGNED: We present a sketch for a nationwide \"Mobility Service Guarantee\" (MSG) for Austria. The approach follows a new paradigm, turning away from car-centric transport policy and planning and towards the extensive provision of public transport. The approach is complemented by the provision of demand-responsive transport services and the support of vehicle sharing as well as active mobility. This combination should serve as an effective alternative option to the use of private cars.
    UNASSIGNED: The aim of this study is to develop a tangible definition of a nationwide MSG in the Austrian context as well as possible design scenarios.
    UNASSIGNED: We took a multi-dimensional approach, using literature review to research existing concepts of mobility guarantees, analysing secondary data on current mobility behaviour and public transport provision and conducting stakeholder workshops.
    UNASSIGNED: We define possible scenarios envisioning a nationwide MSG including different extents of maximum distance to public transport stops and minimum frequency. We discuss the limitations of the MSG with respect to spatial, temporal and modal coverage, as well as how such a guarantee could be embedded in the existing legal system.
    UNASSIGNED: We conclude that a nationwide MSG could be an important element of sustainable transport policy that should be embedded in a wider strategy of infrastructure and service design as well as demand management.
