While super apps such as WeChat and Alipay are well-established in many Asian markets, their adoption in Western markets remains largely underexplored. This study addresses this gap by examining consumer intentions to adopt transport super apps in Germany, where platforms like Uber and Bolt are beginning to introduce the super app concept. Combining Partial Least Squares Structural Equation Modeling (PLS-SEM) and Necessary Condition Analysis (NCA), data from 575 potential users were analyzed. The results reveal that performance expectancy (PE), price value (PV), and habit (HA) significantly impact behavioral intentions to use transport super apps. Notably, PE and PV are necessary conditions for consumer adoption to manifest. Achieving the highest level of adoption intention requires meeting minimum threshold levels of 35.6% for PE and 12% for PV. Moreover, "app fatigue" was found to positively influence adoption, suggesting that super apps are perceived as convenient replacements for multiple single-purpose apps. The insights from this study highlight the importance of tailoring marketing strategies to emphasize transport super apps' valued benefits for key target groups. This research contributes to the emerging literature on super apps, highlighting the need for sector-specific investigations across various super app categories.

While previous literature has often narrowly defined positive driver behaviors as politeness and prosocial behaviors, this study argues for a broader scope, including safety and eco-friendly tendencies. To explore this expanded scope and its connection to driving and safety, both qualitative and quantitative methods were employed. Study 1 aimed to investigate the multidimensional nature of positive driver behaviors. To achieve this, sixteen semi-structured interviews were conducted to develop the Multidimensional Positive Driver Behavior Questionnaire (M - PDBQ). In the subsequent study, the psychometric properties of the M - PDBQ and its relationship with driving-related variables (e.g., risky driver behaviors and aggressive driving), and road safety outcomes (e.g., traffic tickets, accidents) were examined with 628 drivers. Exploratory Factor Analysis identified three key dimensions: smooth and proactive mobility, environmentally sustainable behaviors, and risk communication, highlighting the multidimensional nature of positive driver behaviors. Hierarchical regression analyses suggested that positive driver behaviors have the potential to enhance road safety by mitigating risky and aggressive driving behaviors such as violations and anger expression. This research advances the understanding of positive driver behaviors by providing a comprehensive conceptualization, developing a new questionnaire to measure it, and investigating its relationship with driving and road safety.

This study examined various types of speeding behaviors in older drivers and examined predictors of these behaviors. A speeding event was defined as driving at any speed above the speed limit for at least 6 s. Speeding events were extracted from the driving data of 58 older drivers, collected by driving recorders. These events were then categorized into short-duration minor, short-duration major, and long-duration speeding events based on both severity and duration. Mixed-effect models were employed to analyze the predictors of speeding behaviors at the trip level. Our findings indicated that participants were involved in an average of 15.9 speeding events per 100 km, with short-duration speeding most common in 30-40 km/h zones, while long-duration speeding occurred more frequently on 60 and 80 km/h roads. Trip characteristics, which reflected the driving environments of each trip, played a crucial role in predicting older drivers' speeding behaviors. Most driving environments that trigger speeding behaviors in other age groups were found to similarly impact older drivers, except for nighttime driving. Most older drivers tend to reduce their involvement in all three categories of speeding behaviors at night, and the degree of selfregulation varies across individuals. Moreover, drivers with poorer trail-making test part B performance were less likely to engage in short-duration major speeding. However, no significant associations were found between sensation seeking or impulsivity and any of the three categories of speeding behaviors. These findings suggest that older drivers may not be able to refrain from speeding in most environments that are conducive to these behaviors, and they may not fully recognize the increased risks associated with speeding.

This study assesses drivers' and motorcyclists' intentions to stop or change lanes when encountering hawkers. To achieve this, an extended theory of planned behavior framework is employed, incorporating perceived crash risk, past experiences with hawkers on urban roads, and empathic concern alongside traditional variables of the theory of planned behavior. A questionnaire survey was conducted among drivers and motorcyclists in Lahore, Pakistan, collecting 1603 valid responses. The data was analyzed using partial least squares structural equation modeling to test the proposed hypotheses. Results indicate that respondents, having positive attitudes of safety towards engaging with hawkers, and those with past experience of such behavior have higher intentions to perform unsafe behaviors, i.e., decelerate/stop or overtake/ change lanes to look and respond to hawkers on the roadside, or to observe people buying goods from the roadside hawkers. The findings highlight the need for incorporating driver education on roadside distractions into licensing programs, alongside policy enforcement and public awareness campaigns, while also promoting urban planning interventions such as designated areas for street vendors to enhance road safety and support their livelihoods.
查看更多>>摘要：The objective of this study is to analyze older adults' familiarity with new transportation options (ride-hailing services, bike-share services, and shared e-scooter services) and their perception towards autonomous vehicles (fully autonomous cars), as well as how transportation barriers influence their familiarity and perceptions, in Arkansas, a predominantly rural state. Data from 775 older adults aged 60 years or older were collected between October 2021 and October 2022. To fulfill the study objective, the study used Latent Class Cluster Analysis to segment older adults into classes based on their familiarity with new transportation options and their perceptions of autonomous vehicles. The effects of transportation barriers on class membership were analyzed by employing a Structural Equation Model. The Latent Class Cluster Analysis (LCCA) identified three distinct groups of older adults based on their familiarity with new mobility services and perceptions of autonomous vehicles (AVs). The first group, Unacquainted Older Adults with Negative Perceptions, lacked familiarity with new transportation options and held negative views on AVs. They were more likely to experience individual-level barriers, including mobility impairments, driving cessation, and lack of smartphone access. The second group, Acquainted Older Adults with Negative Perceptions, was aware of ride-hailing, car-sharing, and micromobility services but remained skeptical about AVs. They primarily faced interpersonal and communitylevel barriers, such as lack of informal rides, limited taxi access, and social support constraints. The third group, Acquainted Older Adults with Positive Perceptions, was the most familiar with new mobility options and exhibited a favorable attitude toward AVs. However, they faced car access limitations and environmental barriers, such as limited public transit and inadequate pedestrian infrastructure. These findings underscore the importance of targeted interventions, technology training, infrastructure improvements, and policy initiatives to enhance familiarity with new transportation options among older adults' mobility and acceptance of AVs.
查看更多>>摘要：Research has shown that aggressive driving behaviours (ADBs) are often initiated via emotional impulses. However, little research to date has explored how feelings of anxiety may translate to aggression on the road. The primary aim of this study was to investigate the links between anxiety and ADB, and to explore the moderating influences that antisocial (psychopathic) traits, anger rumination, and emotion dysregulation hold toward this relationship. To achieve this, a sample of adult Australian drivers (N = 386; 61 % women; Mage = 50 years) completed an online survey battery. A MANOVA revealed that driving anxiety, anger rumination, emotion dysregulation, antisocial traits, and ADBs significantly differed between groups categorised by mild, moderate, and severe generalised anxiety; with higher scores largely being tied to more severe anxiety. Next, correlational analysis indicated that there were significant positive associations between anxiety (generalised and driving-related), anger rumination, antisocial traits, driving anger, and various ADBs. Finally, moderation analyses suggested that driving anxiety influenced ADBs in unique ways, depending on the context of participants' anger rumination, emotion dysregulation, and antisocial traits. Specifically, conditional effects showed that where driving anxiety negatively predicted ADB after accounting for anger rumination at low levels, it was found to positively predict ADB when emotion dysregulation was high and antisocial traits were moderate or high. The findings of this study provide a greater understanding of how driving anxiety may manifest into aberrant and emotion-directed behaviours when driving on the road. Such findings could inform future road safety research and practice about the potential roles that self-regulatory factors play in understanding and intervening on ADB.

Experienced consumers' evaluations of AT rides are vital for the advancement of both the industry and related policies. This study aims to reveal the factors that influence the continuous use intention of ATs. A questionnaire survey was implemented and gathered 600 valid responses from Chinese urban residents who have prior experience riding ATs, encompassing four key aspects: sociodemographic and mobility attributes, perceived satisfaction with AT services, properties of the last AT trip, and AT use experiences and outlooks. The analysis was conducted using the LightGBM ensemble learning method, and the interpretation was based on SHAP algorithms. The findings indicate that the most crucial factor is the number of AT rides taken, with three experiences serving as a threshold for promoting the willingness to continue using ATs. Trip durations of 25 min influence respondents' expectations of AT pricing, with shorter trips anticipated to be priced similarly or lower than traditional taxis and ride-hailing services. The peak AT-hailing hours are between 11:00 and 15:00. Enhancing the dynamic performance of ATs is crucial for improving user experience and intention. Furthermore, for individuals under 32 years old, ATs represent a novel, high-tech, and appealing mode of transport. Older adults are less inclined to consider ATs as an alternative to their current transport modes. User satisfaction with in-vehicle interactions can mediate the impact of overall trip satisfaction on the continuous use intention of ATs. Regarding future activity scenarios with ATs, respondents express a willingness to use them for commuting and leisure but strongly oppose their use for picking up children. The paper concludes by presenting theoretical and industrial implications, along with strategies to enhance the continuous use intention of ATs.

This study investigates the relationship between parental bicycle helmet use and their children, focusing on parental attitudes and behaviours. The study was conducted in S & Oslash;r-Tr & Oslash;ndelag, Norway, with 103 parent-child dyads (children aged 10-16) using convenience sampling and a cross-sectional survey. The primary aim was to assess whether parental attitudes or behaviours more strongly predict children's helmet use and examine if child age and sex moderate these relationships. The survey evaluated cycling frequency, helmet use, perceived social norms and the costs and benefits of helmet use. Although nearly all children owned helmets, they wore them less frequently than their parents. A positive correlation was observed between parent and child helmet-wearing and cycling, indicating parental behaviour's significant role in shaping children's safety practices. An Actor-Partner Interdependence Model was used to understand the attitudes and behaviour of children in relation to helmet wearing, while accounting for the influence of the parent attitudes and behaviour. When this dyadic relationship was considered, the impact of parental attitudes on children's helmet use was indirect, mediated through children's own attitudes, and younger children mimicked parental behaviour more than older children. These findings highlight the importance of parental modelling in encouraging helmet use. Interventions should focus on enhancing parental engagement and addressing children's perceived barriers. By elucidating the dynamics of parental influence, this research aids in developing effective safety campaigns to promote helmet use and cycling safety for young cyclists.
查看更多>>摘要：Road signs are there to inform or warn drivers and help drivers to select appropriate speeds and be appropriately aware for hazards. The "older person" warning sign is used in many countries, placed near older people's homes and schools, to warn drivers of potentially vulnerable older pedestrians in the vicinity. The sign often depicts a silhouette of an older couple hunched over within a warning triangle and is a rather negative stereotype of older people. It is questionable whether this sign is useful in slowing drivers down, especially given the potential of the sign to reinforce negative stereotypes. This study used a Driving Simulator to determine whether the "older person" warning sign makes any useful difference to driver behaviour. Drivers were randomly allocated into a group that observed a "older person" warning sign (n = 20) and a group that saw a generic pedestrian warning sign (n = 20). The drivers in the "older person" warning sign group did not alter their speed or braking when observing the sign, regardless of age and gender. The drivers in the pedestrian warning sign group did significantly reduce their speed and used braking when seeing the sign. The "older person" warning sign made no difference to significant driver behaviour and it is suggested it should be removed or replaced by the pedestrian sign.

查看更多>>摘要：While walking behaviour has been extensively studied in the Global North, there remains a significant gap in understanding walking in the Global South, particularly in Africa. Existing research predominantly emphasises the influence of the built environment, often overlooking critical individual and social factors. This study examines the psychological constructs in walking for transportation in Kumasi, Ghana, through the lenses of the Theory of Planned Behaviour (TPB). A structural model of the data collected from 693 participants revealed that intention is strongly associated with walking behaviour, with perceived behavioural control emerging as the primary factor related to intention. Contrary to many studies, attitude did not significantly predict walking intentions, suggesting that local contextual factors such as traffic safety concerns and sidewalk obstructions may diminish the role of affective and cognitive evaluations in walking decisions. Subjective norm also showed no direct association with intention, although it correlated with other TPB constructs. These findings highlight the relevance of TPB in capturing psychological determinants of walking behaviour in an African urban setting. To the best of our knowledge, this research is the first to employ the Theory of Planned Behaviour to explain walking behaviour in an African context, providing a reference for future research and urban transport planning in Ghana and similar settings.
