The current study aims to understand the dynamics between the importance people place on different car characteristics when purchasing a car (labelled as car-related attitudes in this study) and their car consumption (car use and the number of cars owned) over time. Using data from the UK Household Longitudinal Study (UKHLS), we conceptualize bidirectional effects between car-related attitudes, the number of cars owned, and car use among those who access at least a car in their households and test how and which element comes first in impacting the other elements over time. Employing a two-wave cross-lagged panel model with a two-year lag on a large-scale sample (n = 17,198), and considering covariates, the results reveal existence of bidirectional but asymmetric effects between these three elements. Interestingly, the number of cars has the greatest effect on the two other elements. Car consumption influences car-related attitudes larger than the reverse effect. In particular, over time, a higher number of cars and higher levels of car use more strongly affect declines in the weight individuals place on environmental considerations when purchasing a car (e.g., engine size, CO2 emissions, or electric propulsion). This effect is larger than that of environmental considerations on shedding cars or reducing car use.
目前的研究旨在了解人们在购买汽车时对不同汽车特征的重视程度(在本研究中被标记为与汽车相关的态度)与他们的汽车消费(汽车使用和拥有的汽车数量)之间的动态关系。利用英国家庭纵向研究(UKHLS)的数据,我们概念化了与汽车相关的态度、拥有汽车的数量和家庭中至少有一辆汽车的人使用汽车之间的双向效应,并测试了随着时间的推移,哪个因素是如何以及哪个因素首先影响其他因素的。在大规模样本(n = 17,198)上采用具有两年滞后的两波交叉滞后面板模型,并考虑协变量,结果表明这三个要素之间存在双向但不对称的影响。有趣的是,汽车的数量对其他两个因素的影响最大。汽车消费对汽车态度的影响大于相反的影响。特别是,随着时间的推移,更多的汽车数量和更高的汽车使用水平会更强烈地影响个人在购买汽车时对环境考虑的权重下降(例如,发动机尺寸,二氧化碳排放或电力推进)。这种影响比减少汽车或减少汽车使用的环境考虑更大。

Trust in autonomous vehicles (AVs) plays a critical role in shaping public policy and fostering their public acceptance. As AV technology advances, measuring trust becomes increasingly important for informing government strategies. Trials currently undertaken in North America, Europe and Asia highlight the need for urban planning and transport policy departments to actively enhance public trust in AVs. This study applies prototype analysis, a technique widely used in psychology, though yet to become part of the standard toolkit in transport research, to investigate the features of trust in AVs. Prototype analysis is a novel ground-up methodology to investigate the cognitive structure of an abstract concept, here, trust in AVs. Rather than transferring human–human trust measures to trust in AVs, this study elicits context-specific constructs that may inform scale development processes through a series of five studies undertaken in Australia: feature generation, ranking/rating, best-worst, reaction time, and vignette analysis. A key outcome is a set of policy recommendations for how government departments can implement practices that can build trust in this future technology, ensuring public confidence keeps pace with technological advancements in autonomous transport.
对自动驾驶汽车(AVs)的信任在制定公共政策和促进公众接受方面发挥着关键作用。随着自动驾驶技术的进步,衡量信任对政府制定战略变得越来越重要。目前在北美、欧洲和亚洲进行的试验表明,城市规划和交通政策部门需要积极提高公众对自动驾驶汽车的信任。本研究采用原型分析(一种在心理学中广泛使用的技术,但尚未成为交通研究标准工具包的一部分)来调查自动驾驶汽车的信任特征。原型分析是一种全新的研究抽象概念认知结构的方法,这里指的是对自动驾驶汽车的信任。本研究并没有将人与人之间的信任措施转移到自动驾驶汽车的信任中,而是通过在澳大利亚进行的一系列五项研究:特征生成、排名/评级、最佳/最差、反应时间和小片段分析,引出了可能为量表开发过程提供信息的情境特定结构。一项关键成果是一系列政策建议,指导政府部门如何实施实践,建立对未来技术的信任,确保公众信心与自动驾驶交通的技术进步保持同步。

There is considerable heterogeneity in the travel behavior of subway passengers. The growing availability of large-scale smart card data offers the valuable opportunity to observe the major share of the passengers over a long period of time to uncover this heterogeneity in travel behavior and devise targeted policies for peak spreading. This study analyzes 7.92 million trip records from Beijing’s subway system—spanning 24 lines and 331 stations—to identify distinct passenger groups based on travel frequency, temporal patterns, and spatial characteristics. Four distinct passenger clusters are identified, and class-specific mode choice models (between subway and bus) are estimated to derive each group’s value of travel time (VOT) and value of travel time reliability (VOR). Results indicate that commuters who take the subway frequently have a higher willingness to pay to improve trip reliability. This indicates that measures like low fare incentives may not be effective in changing the travel behavior of this group, while they are the main target group for alleviating the subway congestion during peak-hours. Therefore, targeted incentives based on the travel characteristics and transport preferences of different passengers could better improve the effectiveness of subway congestion management.
地铁乘客出行行为存在较大的异质性。越来越多的大规模智能卡数据提供了宝贵的机会,可以在很长一段时间内观察乘客的主要份额,从而揭示旅行行为的异质性,并针对高峰传播制定有针对性的政策。本研究分析了北京地铁系统的792万次出行记录,跨越24条线路和331个站点,根据出行频率、时间模式和空间特征来识别不同的乘客群体。识别出四个不同的乘客群体,并估计出特定类别的模式选择模型(地铁和公共汽车之间),从而得出每个群体的旅行时间值(VOT)和旅行时间可靠性值(VOR)。结果表明,频繁乘坐地铁的通勤者有更高的支付意愿来提高出行可靠性。这表明,低票价激励等措施可能无法有效改变这一群体的出行行为,而这一群体是缓解高峰时段地铁拥堵的主要目标群体。因此,针对不同乘客的出行特征和出行偏好进行有针对性的激励,可以更好地提高地铁拥堵管理的有效性。

This paper investigates the day-to-day variability in the trade-offs between online activities (telecommuting and e-shopping) and out-of-home travel behaviours using a seven-day travel diaries dataset collected in the Greater Toronto and Hamilton Area, Canada. This investigation is particularly relevant, given the shifts towards telecommuting and the influence of Information and communication technology (ICT) on daily life. The analysis of variance results confirmed that day-to-day intrapersonal variability dominates the total variability in the number of trips, travel time expenditure, and distance travelled during a week. The Box-Cox regression results show that regular commuters are associated with more stable trip rates. Adopting telecommuting and online cooked meal delivery (CMD) are correlated with increased trip rate variability. However, frequent CMD users and workers with hybrid workplace arrangements are correlated with consistent travel distances during the weekdays. This study’s findings warrant a multi-day approach to evaluate ICT-related impact on travel demand.
本文使用在加拿大大多伦多和汉密尔顿地区收集的7天旅行日记数据集,调查了在线活动(远程办公和电子购物)和外出旅行行为之间权衡的日常变化。考虑到向远程通勤的转变以及信息和通信技术对日常生活的影响,这项调查尤为重要。方差分析结果证实,每天的个人变异在旅行次数、旅行时间支出和一周旅行距离的总变异中占主导地位。Box-Cox回归结果显示,常规通勤者的出行率更稳定。采用远程办公和在线熟食配送(CMD)与旅行率变异性增加相关。然而,频繁的CMD用户和混合工作场所安排的员工与工作日的一致旅行距离相关。这项研究的结果表明,有必要采用多日方法来评估ict对旅行需求的影响。

Many countries are on the verge of introducing highly autonomous vehicles (AVs) into current traffic networks dominated by human-driven vehicles. The complex and dynamic nature of road traffic situations requires AVs to exhibit human-like, discretionary behaviours that may fall outside the scope of formal Rules of the Road (e.g., straddling solid lines to let an emergency-services vehicle pass). It is important to understand public attitudes towards these behaviours especially when they may lead to negative outcomes. The current paper presents three experiments in which participants’ judgements of blame and trust were probed after being presented with traffic scenarios where AVs or human drivers chose to perform (Experiment 1 & 2) or not perform (Experiment 3) legal or illegal discretionary actions (DAs) to avoid a danger or optimize traffic flow, with various consequences. The results reveal that AVs were blamed more and trusted less than human drivers for performing the same illegal DAs. But with legal DAs, this difference was contingent on the acuteness of traffic situations, hinting toward a shift of judgemental focus from the justifiability of an action to the quality of their execution. Additionally, witnessing AVs performing (or not performing) DAs could potentially improve or worsen their general acceptance depending on the outcomes of the DAs. Our findings paint a promising picture of allowing adaptive behaviours of AVs yet highlight the need to establish formal protocols for designing, regulating, and appraising DAs of AVs as well as the necessity of improving the transparency of their decision-making processes for users.
许多国家即将将高度自动驾驶汽车(AVs)引入当前由人类驾驶的车辆主导的交通网络。道路交通情况的复杂性和动态性要求自动驾驶汽车表现出类似人类的自由裁量行为,这些行为可能超出正式道路规则的范围(例如,跨越实线让紧急服务车辆通过)。重要的是要了解公众对这些行为的态度,特别是当它们可能导致负面结果时。本论文提出了三个实验,在这些实验中,研究人员向参与者展示了自动驾驶汽车或人类驾驶员选择执行(实验1 & 2)或不执行(实验3)合法或非法的自由裁量行为(DAs)以避免危险或优化交通流量并产生各种后果的交通场景后,研究了参与者对责备和信任的判断。结果显示,与人类司机相比,自动驾驶汽车在进行同样的非法自动驾驶时受到了更多的指责和信任。但对于法律da,这种差异取决于交通状况的严重程度,这暗示着判断的重点从行为的正当性转向了执行的质量。此外,目睹自动驾驶汽车执行(或不执行)DAs可能会提高或降低他们的普遍接受程度,这取决于DAs的结果。我们的研究结果描绘了一幅允许自动驾驶汽车自适应行为的美好图景,但也强调了建立设计、规范和评估自动驾驶汽车DAs的正式协议的必要性,以及提高用户决策过程透明度的必要性。

Does micromobility always contribute to traffic emission reduction? Modeling vehicle interactions in heterogeneous traffic flows 微交通是否总是有助于减少交通排放?异构交通流中车辆交互建模

Micromobility, comprising small, lightweight vehicles, has gained popularity globally as a sustainable solution for achieving climate neutrality in metropolitan areas. While micromobility offers environmental benefits such as energy savings and emission reductions, interactions between micromobility vehicles (MMVs) and motor vehicles (MVs) can disrupt regular traffic flow and undermine these efforts. Given the dominance of regular bicycles (RBs) and electric bicycles (EBs) in China, this study focuses on these two modes as representatives for MMVs and proposes an improved heterogeneous flow simulation model to analyze the impact of MMV behaviors on MV operating dynamics. Observed MMVs behaviors (e.g., invasion and spilling) are modeled and defined as distinct lateral and longitudinal movement rules for RBs and EBs due to their different movement characteristics. A vehicle-specific-power-based (VSP-based) model with localized emission parameters is applied for accurate tailpipe emissions estimation, contrasting with traditional regression model. Field data from Beijing, China were collected for model calibration and validation, achieving an average deviation in simulated vehicle speeds of 4.70%. Results indicate that MMV interactions contribute up to 6.26% and 17.16% increases in NOx and CO emissions, respectively.

微型交通工具,包括小型、轻型车辆,作为实现大都市气候中和的可持续解决方案,在全球范围内受到欢迎。虽然微型交通具有节能减排等环境效益,但微型交通工具(mmv)和机动车辆(mv)之间的相互作用可能会扰乱正常的交通流量,并破坏这些努力。鉴于中国以普通自行车(RBs)和电动自行车(EBs)为主,本研究以这两种模式为代表的交通工具为研究对象,提出了一种改进的异质性流模拟模型,分析了交通工具行为对交通工具运行动力学的影响。观察到的mmv行为(例如入侵和溢出)由于其不同的运动特征而被建模并定义为RBs和EBs不同的横向和纵向运动规则。与传统的回归模型相比,采用基于车辆比功率(vsp)的局部化排放参数模型对汽车尾气排放进行精确估计。收集中国北京的现场数据进行模型校准和验证,模拟车速的平均偏差为4.70%。结果表明,MMV相互作用对NOx和CO排放量的贡献分别高达6.26%和17.16%。此外,与仅采用rb的方案相比,采用EB分别减少了18.22%和8.48%的二氧化碳和HC排放。本研究进一步探讨了各种微交通政策的适用性和效果,包括出行需求管理、设置专用车道、提高电动汽车普及率和交通平静化。根据MV和MMV密度调整微交通政策对于防止不成比例的减排努力至关重要。该模型增强了对微流动性对脱碳目标潜在负面影响的理解,为政策制定者评估和促进微流动性政策的有效性提供了有效工具。

While micromobility offers environmental benefits such as energy savings and emission reductions, interactions between micromobility vehicles (MMVs) and motor vehicles (MVs) can disrupt regular traffic flow and undermine these efforts. Given the dominance of regular bicycles (RBs) and electric bicycles (EBs) in China, this study focuses on these two modes as representatives for MMVs and proposes an improved heterogeneous flow simulation model to analyze the impact of MMV behaviors on MV operating dynamics. Observed MMVs behaviors (e.g., invasion and spilling) are modeled and defined as distinct lateral and longitudinal movement rules for RBs and EBs due to their different movement characteristics. A vehicle-specific-power-based (VSP-based) model with localized emission parameters is applied for accurate tailpipe emissions estimation, contrasting with traditional regression model. Field data from Beijing, China were collected for model calibration and validation, achieving an average deviation in simulated vehicle speeds of 4.70%.
