As mobility is an essential part of modern life, people spend a substantial amount of time travelling. This paper investigates how people travelling in Switzerland use and evaluate their travel time, using a quantitative online survey (N = 2,056). While considering a representative distribution of trip purposes and a broad variety of transport modes, the survey focused on a recent trip made by participants. Participants reported their activities while travelling and evaluated the usefulness of their travel time.
Findings show that most travellers did not perceive their travel time as being wasted. Instead, many used it to relax, consume media, reflect, or engage socially – activities that varied substantially depending on the transport mode. For example, passengers on long-distance trains were more likely to read, work, or engage in digital media. Car drivers reported focusing on the ride or listening to audio content. Walking and cycling were often associated with physical activity and personal reflection.
Regression analyses further revealed that trip duration, transport mode, and activity type significantly influence how travellers evaluate the usefulness of their travel time. Perceived usefulness of travel time was highest among train passengers and lowest among car users and cyclists, highlighting the importance of attentional demands.

Background
Long-haul truck drivers (LHTD) routinely navigate challenging driving environments, which requires high levels of visual, cognitive, and physical functioning. While prior studies in older adults have demonstrated significant associations between functional abilities, self-perceptions, and driving performance, these relationships have not been examined among LHTD.
Objectives
The objectives of this study are to: (1) describe LHTD perceptions; (2) examine the associations between clinical test scores and driver perceptions; and (3) examine the associations between driver perceptions and simulated driving errors.
Methods
LHTD were recruited from various provincial and federal trucking associations and trucking companies across Canada. A sample of 36 LHTD completed a demographic questionnaire; objective health measures; Driving Comfort Scales (DCS) and Perceived Driving Abilities Scale (PDA); cognitive, visual, and motor tests; and two simulated drives with different environmental conditions.
Results
The mean age of the sample was 47.9 ± 12.3 years (range 22–69); 94.4 % were men. LHTD were highly comfortable driving during the day (DCS-D: 85.3 ± 9.2) and at night (DCS-N: 80.8 ± 12.3), however, their DCS-N scores were significantly positively associated with vehicle position, speed regulation, and adjustment to stimuli errors. Poorer scores on the RPWT, TMTA, and TMTB were significantly associated with lower driving comfort in scenarios that require quick decision-making (e.g., heavy traffic, other drivers not signaling).
Conclusions
The study highlights the significant role of physical and cognitive abilities in shaping LHTD self-perceptions, particularly in challenging conditions. To improve cognitive and on-road driving performance, future research should explore the development of a continuing education course for LHTD.

Drivers must make lane-change decisions while interacting with surrounding vehicles in complex traffic environments. These decisions are highly sensitive to lane risk status, which leads to different behavioural outcomes. However, existing studies have not systematically explored the motivations and mechanisms of lane-changing behaviour under varying lane conditions. This study proposes a novel analytical framework using the highD dataset to examine how lane risk status affects drivers’ decision-making. By cross-classifying the status of the original and target lanes, four typical lane-change scenarios are identified. A two-stage method combining Association Rule Learning (ARL) and Structural Equation Modelling (SEM) is developed to extract behavioural patterns and establish interpretable causal mechanisms. Results show that drivers adopt distinct decision strategies under different lane-risk combinations. When the original lane is safe, they tend to prioritise greater headway for comfort, but excessive speed, neglect of speed differences, and the avoidance of large vehicles can increase the likelihood of risky lane changes. Conversely, when the original lane is risky, hazard avoidance and distance advantages become dominant, while vehicle-type preferences diminish. Moreover, the status of the target lane shifts drivers’ decision priorities. A safe target lane promotes the use of speed advantages to escape danger, while a risky target lane makes vehicle type the primary concern. These findings enhance the understanding of context-adaptive driving behaviour and provide theoretical support for intelligent lane-change strategies in autonomous driving systems.

Deficiencies in Hazard Management (HM) and Speed Management (SM) skills have been widely recognised as leading contributing factors to the high crash rate with young novice drivers. Although existing training programmes have shown to be effective in enhancing either HM or SM individually, the extent to which these skills transfer remains unknown. Therefore, the aim of the present research is to investigate if training interventions targeting one skill set, such as HM training, generalise to SM skills, and vice versa. Ninety young novice drivers were randomly assigned to one of five training conditions: Control, Implicit Training, Combined Feedback, HM Training, and HM Training with HM Feedback, and subsequently assessed on HM and SM performance across two post-training sessions (immediately after training and one-week post training) using a fixed-base driving simulator. The results revealed the benefit (significantly improved hazard mitigation) of ‘HM Training with HM Feedback’ for both concealed (i.e., Environmental Prediction) and divided focus (i.e., Divided Focus and Attention) hazards, but not hazards that were visible to participants (i.e., Behavioural Prediction), and this effect lasted up to one-week post training. In terms of SM, the ‘Combined Feedback’ group consistently showed improved SM skills (spent less time over the speed limit), and this effect was most evident in the lower speed zone of 50 km/h, as opposed to 80 km/h. This effect was also evident one-week post training. In terms of skills transfer, no skill generalisation occurred between HM and SM. These findings underscore the need for innovative training approaches that can simultaneously develop both critical competencies concurrently and enhance the overall safety of young drivers.

Young drivers represent a high-risk group worldwide, with their overrepresentation in road trauma placing substantial pressure on health and economic systems. Their crashes are often linked to risky driving behaviors, accentuating the need for reliable instruments to assess these patterns. The Behavior of Young Novice Drivers Scale (BYNDS) was developed to comprehensively assess multiple dimensions of risky driving behavior in drivers aged 17–29 years; however, it has not yet undergone cross-cultural validation.
Aim
This study aimed to conduct a comprehensive cross-cultural validation of the BYNDS and examine differences in risky driving behaviors among young drivers from Low- and Middle-Income (LMIC) and High-Income (HIC) countries.
Method
Data were collected from a cross-sectional sample of n = 3,989 young drivers aged M = 22.25 years, of whom 52 % were male and 48 % female. Participants completed the BYNDS, a 44-item behavioral questionnaire administered across 12 countries (48.6 % LMICs; 51.4 % HICs) spanning five continents.
Results
The findings indicate that the BYNDS supports a five-factor structure with good fit indices, strong factor loadings, and acceptable reliability, and invariance between countries of different income levels. Furthermore, the validated BYNDS-42 (comprising 42 items distributed across five factors) also showed the ability to distinguish between drivers with and without self-reported crashes or traffic fines.
Conclusion
This study provides robust evidence supporting the cross-cultural validity and reliability of the BYNDS, reinforcing its value as a tool for assessing young driver behavior. These findings offer empirically grounded insights that can inform behavioral interventions aimed at improving young drivers’ road safety.

The present eye-tracking study explores differences in the dynamics of visual attention in tram drivers with different levels of expertise while driving a tram simulator. Experienced (n = 25) and novice (n = 20) drivers performed a simulator drive on a pre-programmed route with three tasks: tram stop operations, track hazards, and turn-taking. These situations elicited different attentional dynamics as a response to task requirements.
First, tram stop operations induced less entropy in drivers’ eye movements than track hazards but not compared to turn-taking. At the beginning of tram stop operations, all drivers were mainly focal. While taking turns, novices switched to ambient attention faster than experts. Analysis of attention allocation to windshields and control panels did not reveal significant differences between experts and novices, suggesting these elements were equally important to both groups. Differences emerged in the analysis of mirrors. Experts exhibited significantly longer total fixation time on mirrors at the first turn-taking stage than novices, and more fixations on mirrors when turning, suggesting a higher control of their surroundings. In general, the scanning patterns of experts tend to be more structured than those of novices. Experts’ dynamics between focal and ambient attention was more relevant to the tram operation demands to maintain safety. Based on these findings, visual attention training for novices will be designed.

Warning systems have two error types: misses (fail to warn during critical events), being a problem when overtrust develops, and false alarms, causing system mistrust (cry-wolf effect). Mistrust can reduce harm from misses but may also prompt undue reactions which may create new hazards. Prior studies suggest systems with up to 30 % misses and false alarms remain beneficial, but seldom assess both errors jointly. We conducted a driving-simulator study with 47 participants across three reliability conditions: (1) 100 % detection with 33 % false alarms; (2) 70 % detection with no false alarms; (3) 70 % detection with 33% false alarms. Participants encountered 100 pedestrian scenarios: standing or approaching pedestrians that stopped (uncritical event; 90 %) or crossed (critical event; 10 %). In condition 1, 33 % false alarms did not impair reactions to critical events but induced non-critical braking. In condition 2, misses led to minimal missed reactions but significantly delayed braking when warnings were absent. In condition 3, drivers reacted faster to correct warnings than in condition 1 and did not brake more slowly during undetected events, indicating that experiencing both error types reduces overtrust while preserving responsiveness. However, condition 3 was subjectively rated as least useful and most annoying. These results highlight a trade-off between objective effectiveness and user acceptance, suggesting that balanced system reliability can enhance driver response, but at the expense of user satisfaction.

In 2022 the UK Highway Code had a major update including advice for cyclists around lane positioning that reflects existing safety training practice and guidance for drivers to leave at least 1.5 m of lateral clearance when overtaking cyclists. This study uses a repeated measures design to examine the impact of changes to the Highway Code on knowledge of cycling road positioning practice, and the effect of this knowledge on perceptions of cyclist discourtesy.
Knowledge of cyclist positioning practice improved significantly between the two surveys. A hierarchical multiple regression found that cyclist positioning knowledge score added significantly to the model predicting perceptions of cyclist discourtesy, with the change in R2 between the two models being significant. A separate hierarchical multiple regression, with cyclist positioning knowledge as the DV and Highway Code knowledge as the additional stage two IV, was not significant.
The findings showed that while the highway code changes did not predict improvements in knowledge, drivers with better knowledge did have more positive opinions of cyclist behaviour, when controlling for their own participation in cycling.
This was a novel study in applying a repeated measures design before and after the changes to the UK Highway Code. The findings will help inform development of interventions designed to improve road safety for cyclists.
