These results offer policymakers practical insights into public perceptions of SAVs, enabling the identification of underlying preferences and the design of targeted strategies to improve SAV adoption.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"113 ","pages":"Pages 158-173"},"PeriodicalIF":3.5,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143912690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the relationship between parental bicycle helmet use and their children, focusing on parental attitudes and behaviours. The study was conducted in Sør-Trøndelag, 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.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"113 ","pages":"Pages 124-135"},"PeriodicalIF":3.5,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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: socio-demographic 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.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"113 ","pages":"Pages 106-123"},"PeriodicalIF":3.5,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143895416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 (<em>N</em> = 386; 61 % women; M^age = 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.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"113 ","pages":"Pages 94-105"},"PeriodicalIF":3.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 self-regulation 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.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"113 ","pages":"Pages 34-53"},"PeriodicalIF":3.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143886213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 community-level 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.
