The rapid growth of ride-hailing services has reshaped urban mobility but also intensified congestion, emissions, and car dependency, raising concerns about sustainability. The metro-integrated multimodal travel (MIMT), enabled by Mobility as a Service (MaaS) platforms, offers promising low-carbon alternatives by integrating metro systems with convenient access and egress modes such as ridesplitting, buses, cycling, and walking. This study aims to develop a pratical analytical framework to assess the substitution potential of MIMT for ride-hailing trips in the era of MaaS. First, a trip reconstruction method is proposed to generate ten types of MIMT alternatives under identical origin–destination (OD) conditions. Second, a multidimensional evaluation model is established to quantify substitution benefits by jointly considering cost savings, carbon emission reductions, and time delays. Third, an interpretable machine learning approach (CatBoost integrated with SHAP and PDP) is applied to identify the travel and built environment factors influencing substitution potential. A case study based on 837,503 ride-hailing trips in Shanghai indicates that 56.46 % of trips could feasibly be replaced by MIMT alternatives. On average, each substituted trip yields a comprehensive benefits of 13.83 CNY, comprising cost savings of 24.03 CNY and carbon emission reductions of 1.29 kg, at the cost of an average travel time increase of 17.51 min. The results further reveal that substitution potential is primarily driven by route nonlinearity, trip distance, and metro accessibility. Travel-related variables account for 61.11 % of explanatory power, while built environment features contribute the remaining 38.89 %. Sensitivity analyses demonstrate that travelers' transition from ride-hailing to MIMT is predominantly influenced by the value of time, with current carbon pricing exerting only a marginal effect. These findings highlight the role of MaaS in promoting multimodal integration and provide actionable insights for policymakers and platform operators to reduce ride-hailing dependency and advance low-carbon urban mobility.
网约车服务的快速增长重塑了城市交通,但也加剧了拥堵、排放和对汽车的依赖,引发了人们对可持续性的担忧。由交通即服务(MaaS)平台支持的地铁综合多式联运(MIMT),通过将地铁系统与便捷的进出方式(如拼车、公共汽车、骑自行车和步行)集成在一起,提供了有前景的低碳替代方案。本研究旨在建立一个实用的分析框架,以评估在MaaS时代,MIMT对网约车的替代潜力。首先,提出了一种行程重构方法,在相同始发目的地条件下生成10种MIMT备选方案。其次,建立多维评价模型,综合考虑成本节约、碳减排和时间延迟,量化替代效益。第三,采用一种可解释的机器学习方法(CatBoost与SHAP和PDP相结合)来识别影响替代潜力的出行和建筑环境因素。一项基于上海837,503次网约车出行的案例研究表明,56.46%的出行可以被MIMT替代。平均而言,每次替代出行的综合效益为13.83元人民币,其中成本节省24.03元人民币,碳排放减少1.29千克,平均出行时间增加17.51分钟。替代潜力主要受路线非线性、行程距离和地铁可达性的影响。旅行相关变量占解释力的61.11%,而建成环境特征贡献了剩余的38.89%。敏感性分析表明,旅客从网约车到移动出行的转变主要受时间价值的影响,当前的碳定价仅发挥边际效应。这些发现突出了MaaS在促进多模式融合方面的作用,并为政策制定者和平台运营商提供了可操作的见解,以减少对网约车的依赖,促进低碳城市交通。

The impact of rail transit infrastructure on residents’ travel satisfaction and subjective well-being has gained increasing attention among researchers and policymakers. However, few studies have used longitudinal data to analyze the causal effects of rail transit systems on travel satisfaction and its underlying mechanisms. This study employed a natural experiment approach, using two waves of survey data (2020 & 2021) from 422 participants in Wuhan, China, to assess the effects of a newly opened subway line on travel satisfaction. Applying a mixed-effects difference-in-differences (DID) method, we found that the new subway line significantly improved residents’ travel satisfaction after accounting for socio-demographic and travel attitude covariates. Mediation analysis revealed that this improvement was primarily driven by increased perceived accessibility to downtown and transit stops or stations, as well as a reduction in the number of out-of-home activities on weekends. Heterogeneous analysis indicated that the subway’s benefits are more pronounced among females, individuals under 60 years old, and those from middle-income households. These findings provide new causal evidence on the link between rail transit infrastructure and travel satisfaction, deepening our understanding of this complex relationship and offering practical insights for formulating strategies to improve urban residents’ quality of life.
轨道交通基础设施对居民出行满意度和主观幸福感的影响越来越受到研究者和决策者的关注。然而,很少有研究利用纵向数据分析轨道交通系统对出行满意度的因果关系及其潜在机制。本研究采用自然实验方法,使用来自中国武汉422名参与者的两波调查数据(2020 & 2021)来评估新开通的地铁线路对旅行满意度的影响。运用混合效应差分法(mixed-effects difference-in-difference, DID),我们发现在考虑社会人口统计学和出行态度协变量后,新地铁线路显著提高了居民的出行满意度。中介分析显示,这种改善主要是由于到市中心和公交站点或车站的可达性增加,以及周末外出活动数量的减少。异质性分析表明,地铁的好处在女性、60岁以下的个体和中等收入家庭中更为明显。这些发现为轨道交通基础设施与出行满意度之间的联系提供了新的因果证据,加深了我们对这种复杂关系的理解,并为制定改善城市居民生活质量的策略提供了实用的见解。

Despite growing global interest in e-scooters as micromobility solutions, limited research has explored factors influencing their adoption in car-dependent, high-income contexts with extreme summer climates. This study addresses this gap through nationwide web-based survey in Qatar, where high private vehicle dependency, summer temperatures exceeding 45 °C, and limited cycling infrastructure as well as limited cycling culture create unique challenges for micromobility integration. The final sample consisted of 2736 respondents (339 e-scooter users and 2397 non-users), capturing usage patterns, demographic information, and non-users’ perceptions of public acceptance and intention to use e-scooters. Among current users, e-scooters were predominantly used for leisure and commuting, with males and notably, individuals without driving licenses using them frequently. Usage patterns differed between ownership types, with shared/rental users predominantly using e-scooters for leisure, while owned e-scooter users primarily used them for commuting. To examine non-users’ perspectives, structural equation modeling was used to assess influence of different factors on usage intention and perceived public acceptance. Findings revealed that regulatory and infrastructure support, along with social influence and preference, were the most significant predictors, while cost and service quality barriers negatively influenced usage intention. Importantly, perceived public acceptance strongly influenced personal intention to use, demonstrating that social legitimacy substantially shapes adoption even in car-oriented contexts. Sociodemographic analysis revealed that car ownership and higher income negatively predicted adoption, while non-license holders, non-Arab residents, and employed individuals showed significantly higher adoption potential. These findings offer valuable insights for policymakers and urban planners in developing targeted interventions to promote safe and sustainable integration of e-scooters. Such interventions include improved infrastructure, effective regulations, competitive pricing, enhanced service quality, and community engagement initiatives. While grounded in Qatar’s context, these findings can be generalized to urban environments globally characterized by high motorization rates, cultural preferences for private vehicles, challenging climatic conditions, and infrastructure limitations.
尽管全球对电动滑板车作为微型交通解决方案的兴趣日益浓厚,但在依赖汽车、高收入、夏季极端气候的环境中,影响电动滑板车采用的因素的研究有限。本研究通过在卡塔尔进行的基于网络的全国性调查解决了这一差距,卡塔尔高度依赖私家车,夏季气温超过45°C,有限的自行车基础设施以及有限的自行车文化为微交通一体化带来了独特的挑战。最终样本包括2736名受访者(339名电动滑板车用户和2397名非用户),获取使用模式、人口统计信息以及非用户对公众接受和使用电动滑板车的意愿的看法。在目前的用户中,电动滑板车主要用于休闲和通勤,男性,特别是没有驾照的个人经常使用它们。不同所有权类型的用户使用模式不同,共享/租赁用户主要将电动滑板车用于休闲,而自有电动滑板车用户主要将其用于通勤。为了检验非使用者的观点,我们使用结构方程模型来评估不同因素对使用意愿和感知公众接受度的影响。调查结果显示,监管和基础设施支持以及社会影响和偏好是最重要的预测因素,而成本和服务质量障碍对使用意愿产生负面影响。重要的是,感知到的公众接受程度强烈地影响了个人的使用意图,这表明即使在以汽车为导向的环境中,社会合法性也在很大程度上影响了使用。社会人口统计分析显示,拥有汽车和高收入负向预测采用率,而没有驾照的人、非阿拉伯居民和有工作的人则显示出更高的采用率潜力。这些发现为政策制定者和城市规划者制定有针对性的干预措施以促进电动滑板车的安全和可持续整合提供了有价值的见解。这些干预措施包括改善基础设施、有效监管、竞争性定价、提高服务质量以及社区参与倡议。虽然基于卡塔尔的背景,但这些发现可以推广到全球的城市环境,这些城市的特点是高机动化率、对私家车的文化偏好、具有挑战性的气候条件和基础设施的限制。

Electric vehicles (EVs) play a pivotal role in advancing sustainable transportation, with ongoing improvements in driving range and charging infrastructure reshaping user expectations—shifting focus from basic functionality to enhanced service experience. Therefore, to examine EV users’ charging behavior, a comprehensive questionnaire survey was performed in this paper. Based on the discrete choice modeling, a Binary Logit (BL) model under the assumption of homogeneous user preferences, and a Latent Class Logit (LC) model considering the unobserved heterogeneity are established. Key findings reveal that charging decisions are significantly influenced by state of charge (SOC), pricing, queueing time, and station accessibility, reflecting user sensitivity to both economic and service-quality factors. Additionally, individual characteristics including age, risk aversion, and ownership of fixed charging locations exert substantial moderating effects. Willingness-to-pay (WTP) analysis further demonstrates that users prioritize service enhancements over mere cost reductions. The LC model delineates two distinct user segments: Class 1 (37.7 %), comprising younger, cost- and efficiency-driven early adopters (predominantly male), and Class 2 (62.3 %), characterized by older, risk-averse users (with higher female representation) who prioritize reliability and initiate charging at lower SOC to mitigate uncertainty. The results underscore the importance of integrating service experience and user heterogeneity into EV infrastructure planning, which provides actionable insights for policymakers and stakeholders to develop tailored, user-centric charging solutions.
电动汽车(ev)在推进可持续交通方面发挥着关键作用,其续驶里程和充电基础设施的不断改进重塑了用户的期望——将重点从基本功能转移到增强的服务体验上。因此,为了检验电动汽车用户的充电行为,本文进行了全面的问卷调查。在离散选择建模的基础上,分别建立了用户偏好同质假设下的二元Logit (BL)模型和考虑不可观测异质性的潜在类Logit (LC)模型。研究发现,充电状态(SOC)、价格、排队时间和充电站可达性对充电决策有显著影响,反映了用户对经济和服务质量因素的敏感性。此外,年龄、风险规避和拥有固定充电地点等个人特征也发挥了实质性的调节作用。付费意愿(WTP)分析进一步表明,用户优先考虑服务增强,而不仅仅是降低成本。LC模型描述了两个不同的用户群体:第1类(37.7%),包括年轻的,成本和效率驱动的早期采用者(主要是男性);第2类(62.3%),其特征是年龄较大,厌恶风险的用户(女性代表较多),他们优先考虑可靠性,并在较低的SOC下开始充电,以减轻不确定性。研究结果强调了将服务体验和用户异质性整合到电动汽车基础设施规划中的重要性,为政策制定者和利益相关者提供了可操作的见解,以制定量身定制的、以用户为中心的充电解决方案。

This study assesses long-distance (LD) travel demand in near-future scenarios where automated vehicles (AVs) are easily available. Stated and revealed preference data were obtained from 1,004 American adults. The survey includes questions about general LD trip-making behavior with AVs, after investigating the possibility of using AVs to substitute for respondents’ recent LD trips (over 75-miles one-way) prior to the COVID-19 pandemic. After cleaning and weighting the responses, respondents’ willingness to use AVs for a past LD trip are shared, and their future travel behaviors with AVs are explored via statistical models. Ordered logit regression model results suggest AVs would increase the trip-making frequency of high-income households, households with more children, and young people who are part-time employed. The multinomial logit model for overnight stopping suggests that high-income travelers prefer staying overnight in hotels, while young and solo-drivers are expected to more often stay overnight in moving AVs. Mornings departures are preferred for LD travel - both with and without AVs, but some travelers shift to later departures when AVs become available, particularly those who are employed full-time and/or have more children in their household. Results of the mode choice model for mid-range LD travel (200 to 500 miles) suggest those who are unmarried and/or employed full time prefer AVs, while those over age 65 do not. Car and AV cost are the most practically significant variables impacting people’s mode choices, and aircraft and AVs are more appealing than human-driven vehicles for trips over 500 miles long.
本研究评估了在不久的将来,自动驾驶汽车(AVs)很容易获得的情况下,长途旅行(LD)的需求。声明和显示的偏好数据来自1004名美国成年人。在调查了在2019冠状病毒病大流行之前使用自动驾驶汽车替代受访者最近的单程75英里以上的自动驾驶汽车旅行的可能性之后,该调查包括了关于自动驾驶汽车的一般LD旅行行为的问题。在对问卷进行清理和加权后,分享受访者在过去的LD旅行中使用自动驾驶汽车的意愿,并通过统计模型探讨他们未来使用自动驾驶汽车的旅行行为。有序logit回归模型结果表明,自动驾驶汽车会增加高收入家庭、子女较多家庭和兼职年轻人的出行频率。过夜停留的多项logit模型表明,高收入的旅行者更喜欢在酒店过夜,而年轻的和独自驾驶的人更倾向于在移动的自动驾驶汽车中过夜。无论有没有自动驾驶汽车,早上出发都是LD旅行的首选,但当自动驾驶汽车可用时,一些旅行者会转向晚一点出发,特别是那些全职工作和/或家中有更多孩子的人。中程长途旅行(200至500英里)模式选择模型的结果表明,未婚和/或全职工作的人更喜欢自动驾驶汽车,而65岁以上的人则不喜欢。汽车和自动驾驶汽车的成本是影响人们出行方式选择的最重要的变量,在500英里以上的行程中,飞机和自动驾驶汽车比人类驾驶的汽车更有吸引力。

Youths on the move: Social disparities in public transportation use among school students 移动中的年轻人:学生中公共交通使用的社会差异

Public transportation (PT) plays a crucial role in catering to the mobility needs of school students. However, the disparities of PT travel characteristics among different socioeconomic groups have been underexplored. In this study, we explore disparities in PT usage, after-school activity participation, journey length, and on-board crowding among different socioeconomic groups as well as between different educational stages (primary, secondary). We specifically focus on home-to-school and school-to-activity PT journeys utilizing automated data sources (smart card data). Results from the case study of Region Stockholm show that travel time and crowding exposure vary across the case study area. Specifically, school students coming from areas with higher income levels, higher shares of cooperative housing, or lower vehicle ownership tend to need less time to travel to school. In terms of student categorization, secondary students with diverse socioeconomic backgrounds tend to travel longer to school compared to primary students. Concerning journeys to after-school activities using PT, results reveal that school students from areas with high vehicle ownership and education or lower employment levels, as well as students from suburban/rural areas, have lower odds of using PT. The findings can assist policy makers and PT agencies in designing more equitable and youth-friendly PT systems, improving access to schools and to after-school activity locations.
公共交通在满足学生出行需求方面起着至关重要的作用。然而,不同社会经济群体间PT旅游特征的差异尚未得到充分的研究。在本研究中,我们探讨了不同社会经济群体以及不同教育阶段(小学、中学)之间PT使用、课外活动参与、旅程长度和车上拥挤程度的差异。我们特别关注使用自动化数据源(智能卡数据)的从家到学校和从学校到活动的PT旅程。斯德哥尔摩地区的案例研究结果表明,在不同的案例研究区域,出行时间和拥挤暴露程度各不相同。具体来说,来自收入水平较高、合作住房比例较高或车辆拥有量较低地区的学生往往需要较少的上学时间。在学生分类方面,不同社会经济背景的中学生比小学生更倾向于上学时间更长。结果显示,车辆拥有量高、受教育程度高或就业水平低的地区的学生,以及郊区/农村地区的学生,使用PT的几率较低。研究结果可以帮助政策制定者和PT机构设计更公平和青年友好的PT系统,改善上学和课后活动地点的可及性。

Numerous studies have examined the effectiveness of urban transportation planning policies such as park-and-ride, transit-oriented development, and multimodal transportation hubs in promoting public transit use. In the past decades, bike sharing, both dockless and docking systems, has been increasingly popular as a green transport mode, connecting to public transit. However, the influence of socioeconomic conditions, land-use factors, transport infrastructure, and station characteristics on bike-and-ride remains underexplored, particularly across different patterns of bike-and-ride. In this study, an integrated random forest (RF) and geographically weighted regression (GWR) model is applied to capture nonlinear relationships and spatial heterogeneity between bike-and-ride usage and explanatory variables, including socioeconomic variables, land-use factors, transportation infrastructure, and metro characteristics, based on the integrated bike sharing and metro ridership data in Chengdu, China. Additionally, a novel similarity metric, Dynamic Time Warping (DTW), is applied to classify the metro stations based on the temporal pattern of bike-and-ride trips at all stations. Hence, four clusters of metro stations with a varying pattern of bike-and-ride trips are established. The results show that the importance of determinants and their association with bike-and-ride vary significantly among different clusters of metro stations. This study proposes a fine-grained analytical framework for bike-and-ride, providing theoretical and empirical support for station function classification.
许多研究已经检验了城市交通规划政策的有效性,如停车换乘、交通导向发展和多式联运枢纽,以促进公共交通的使用。在过去的几十年里,共享单车作为一种连接公共交通的绿色交通方式,无论是无桩还是有坞系统,都越来越受欢迎。然而,社会经济条件、土地利用因素、交通基础设施和车站特征对自行车骑行的影响仍未得到充分探讨,特别是在不同的自行车骑行模式中。本文基于成都市共享单车和地铁出行数据,采用随机森林(RF)和地理加权回归(GWR)模型,分析了共享单车使用与社会经济变量、土地利用因子、交通基础设施和地铁特征等解释变量之间的非线性关系和空间异质性。在此基础上,提出了一种新的相似性度量——动态时间扭曲(Dynamic Time Warping, DTW),基于各车站的骑车出行时间模式对地铁站进行分类。因此,建立了四个具有不同模式的自行车和骑行的地铁站群。结果表明,在不同的地铁车站群中,决定因素的重要性及其与骑车出行的关系存在显著差异。本研究提出了自行车骑行的细粒度分析框架,为车站功能分类提供理论和实证支持。

Do Pedestrians Respond Differently to Perceived Vehicle Automation in Monitor-based and Head-Mounted immersive Experiments? 在基于监视器和头戴式沉浸式实验中,行人对感知到的车辆自动化反应不同吗?

Due to limited historical data on interactions of pedestrians with autonomous vehicles (AVs), researchers commonly use stated preference experiments to study pedestrians’ perceived ease of interactions with AVs. Virtual reality implemented via head-mounted displays (HMDs) provides a three-dimensional representation of pedestrian–AV encounters that may enhance realism and elicit responses similar to those in real life. However, the mechanisms by which HMDs confer this advantage remain unclear. To this end, we systematically compare HMD-based and monitor-based experimental formats in their ability to capture behavioral, physiological (i.e., stress biomarkers), psychological (i.e., brain data), and self-reported measures of pedestrian-AV interaction. In a controlled within-subject design, we find that in the HMD condition, pedestrians’ initial trust in AVs translates into statistically detectable differences across these measures while pedestrians interact with AVs and human-driven vehicles; by contrast, the monitor-based condition, tested with the same participants and identical stimuli, fails to detect such effects. The greater immersion in the HMD condition is further supported by a higher propensity to look around (behavioral measure) and by increased cognitive load derived from neurophysiological signals, both of which indicate enhanced perceptual realism. These results underscore the value of immersive 3D experiments for studying pedestrian-AV interaction over 2D picture/video-based experiments.
由于行人与自动驾驶汽车交互的历史数据有限,研究人员通常使用陈述偏好实验来研究行人与自动驾驶汽车交互的感知难易程度。通过头戴式显示器(hmd)实现的虚拟现实提供了行人与自动驾驶汽车相遇的三维表示,可以增强真实感,并引发与现实生活中类似的反应。然而,hmd赋予这种优势的机制尚不清楚。为此,我们系统地比较了基于hmd和基于监视器的实验格式在捕获行人与自动驾驶汽车相互作用的行为、生理(即压力生物标志物)、心理(即大脑数据)和自我报告测量方面的能力。在受控的受试者内设计中,我们发现在HMD条件下,行人对自动驾驶汽车的初始信任转化为统计上可检测的差异,而行人与自动驾驶汽车和人类驾驶的车辆相互作用;相比之下,在同样的参与者和相同的刺激下进行的基于监视器的条件测试中,没有检测到这种影响。在HMD条件下,更大的沉浸感进一步得到了更高的环顾倾向(行为测量)和来自神经生理信号的认知负荷增加的支持,这两者都表明增强的感知现实主义。这些结果强调了沉浸式3D实验在研究行人与自动驾驶汽车互动方面的价值,而不是基于2D图片/视频的实验。

Uneven crowding across metro networks, where some lines are severely congested while others remain underutilized, undermines passenger satisfaction and network efficiency. This study examines the potential of coordinated feeder bus services to divert passengers from overcrowded to less crowded lines, using Chengdu, China, as a case study. To assess passenger willingness to switch and capture preference heterogeneity, a stated preference experiment and latent class model were applied under scenarios where the current travel mode was either metro-walking or metro-bus. Two passenger classes were identified. Class A comprised mainly frequent commuters who used the metro at least three days per week. They were highly responsive to service attributes, willing to accept substantially longer metro travel to avoid crowding and transfers, moderate extensions to reduce cost, but only minimal increases in walking or bus access time. Class B, comprising low-frequency, off-peak, and non-commuting passengers, displayed strong inertia and switched only with clear improvements in comfort or walking access. Across scenarios, Class A, particularly metro-bus commuters facing severe crowding and multiple transfers, emerged as the group most likely to switch. Elasticity and sensitivity analyses for Class A further revealed that more severe crowding or transfers on the current route produce stronger switching effects: as crowding intensifies, larger discounts are required to divert passengers to worse alternatives, whereas only modest or no incentives suffice to attract them to better ones. Overall, the findings provide robust evidence that improving feeder bus accessibility can encourage commuters to shift to less crowded metro lines, particularly when combined with service enhancements and targeted incentives.
地铁网络的不均匀拥挤,一些线路严重拥挤,而另一些线路却没有得到充分利用,这降低了乘客的满意度和网络效率。本研究以中国成都为例,探讨协调接驳巴士服务将乘客从拥挤的线路转移到不那么拥挤的线路的潜力。为了评估乘客的换乘意愿并捕捉偏好异质性,采用陈述偏好实验和潜在类别模型,对当前出行方式为地铁步行或地铁公交的情景进行了研究。乘客分为两个阶层。A类人群主要是每周至少有三天乘坐地铁的频繁通勤者。他们对服务属性非常敏感,愿意接受更长的地铁旅行,以避免拥挤和换乘,适度延长以降低成本,但步行或公交时间只增加很少。B类,包括低频、非高峰和非通勤乘客,表现出强烈的惯性,只有在舒适度或步行通道明显改善时才会切换。在各种情况下,A类乘客,尤其是面临严重拥挤和多次换乘的地铁乘客,是最有可能换乘地铁的人群。对A级的弹性和敏感性分析进一步表明,当前路线上更严重的拥挤或换乘会产生更强的换乘效应:当拥挤加剧时,需要更大的折扣才能将乘客转移到较差的替代方案,而只需适度或没有足够的激励就足以吸引他们前往较好的替代方案。总的来说,研究结果提供了有力的证据,表明改善接驳巴士的可达性可以鼓励通勤者转向不那么拥挤的地铁线路,特别是在结合服务改善和有针对性的激励措施的情况下。

This article proposes an evidence-based policy recommendation framework integrating social media data and natural language processing methods, to support inclusive and efficient transport policy-making. Given that current research underscores the crucial role of both external and psychological variables in individual travel decisions, psychological features – such as beliefs, attitudes or values – are frequently used as latent variables for travel behaviour interpretation and travel choice modelling. However, user-centric policy recommendations based on dynamic psychological variables are still limited. Most studies rely on survey data, which neglects the urgent dynamic trend of user perception change and its underlying relationship with travel behaviour. Hence there is a lack of illustration on how these psychological variables can be further used at specific temporal and spatial levels for travel behaviour interpretation. This would be valuable to identify priorities for more targeted (sustainability and other) policies and interventions. In this article, we utilize sentiment analysis and dynamic topic modelling to represent the spatial–temporal variance of psychological features. Integrating with corresponding travel behaviour, we illustrate how these dynamic psychological features can distinguish travel dissonance, identify key motivations, and reflect urgent social demands at precise spatial–temporal levels. We demonstrate these advances in a case study in New York City from 2019 to 2022 using Twitter (X) data. A comparison with existing travel-related policies in the case study validates the feasibility of our framework to support evidence-based policy recommendations. We conclude by discussing the potential of this framework to support sustainable transport promotion.
本文提出了一个基于证据的政策建议框架,整合社交媒体数据和自然语言处理方法,以支持包容性和高效的交通政策制定。鉴于目前的研究强调了外部变量和心理变量在个人旅行决策中的关键作用,心理特征——如信仰、态度或价值观——经常被用作旅行行为解释和旅行选择建模的潜在变量。然而,基于动态心理变量的以用户为中心的政策建议仍然有限。大多数研究依赖于调查数据,忽视了用户感知变化的迫切动态趋势及其与出行行为的潜在关系。因此,缺乏关于如何在特定的时间和空间水平上进一步使用这些心理变量来解释旅行行为的说明。这对于确定更有针对性的(可持续性和其他)政策和干预措施的优先事项将是有价值的。本文利用情感分析和动态主题建模来表征心理特征的时空变异。结合相应的旅行行为,我们说明了这些动态心理特征如何区分旅行失调,识别关键动机,并在精确的时空水平上反映紧迫的社会需求。我们使用Twitter (X)数据在2019年至2022年期间在纽约市进行的案例研究中展示了这些进步。案例研究中与现有旅游相关政策的比较验证了我们的框架支持循证政策建议的可行性。最后,我们讨论了该框架在支持可持续交通推广方面的潜力。
