A Paper titled “Traffic safety culture within the safe system: developing a common definition of traffic safety culture” authored by Tor-Olav Nævestad, Uta Meesmann, Henriette Wallén Warner, Susanne Kaiser, Ingeborg S. Hesjevoll, Vibeke Milch, Sonja Forward, Mathias De Roeck, Michael Schachner, Dimitris Nikolaou, Gunilla Björklund, Alexandra Laiou, Hanna Wennberg, Eva Aigner-Breuss and Anita Eichhorn was recently published in Frontiers in Sustainable Cities. This study developed the following definition of traffic safety culture, based on a three-step refinement approach, combining literature reviews, Delphi studies and focus group discussions: “Traffic safety culture encompasses shared values, beliefs, attitudes, norms, and patterns of behaviours that shape how traffic safety is understood and enacted within a meaningfully defined group of actors in the transport system. This meaningfully defined group of actors can refer to road users, organizations, authorities, or other actors within the transport system.”

A Paper titled “Social values behind the wheel: How does social value orientation shape speeding behaviour across drivers in Europe?” authored by Amir Hossein Kalantari, Amna Chaudhry, Mark Burke, Ana María Pérez-Zuriaga, Apostolos Ziakopoulos, Eleonora Papadimitriou, Shanna Lucchesi and Amir Pooyan Afghari was recently published in Transportation Research Part F: Psychology and Behaviour, The Study examined how Social Value Orientation (SVO), a personality trait capturing tendencies toward altruism, cooperation or competitiveness, is associated with drivers’ stated propensity to speed across three European urban contexts, the West Midlands (UK), Athens and Valencia, using Random-Parameters Ordered Probit models with heterogeneity in the means. Results show that road design, traffic density and speed enforcement are associated with self-reported speeding, but these associations vary substantially across contexts and drivers. Furthermore, in the West Midlands, a stronger prosocial orientation weakened the links between behavioral risk constructs and stated speeding, while in Athens the same trait mainly strengthened the association between speeding tendencies and speeding propensity. The study suggests that speed-management strategies may be more effective when physical design and enforcement are paired with communication that presents speed limits as credible, locally relevant and clearly connected to the safety of other road users.
A paper titled Physical Fitness and Highway Driving Performance: Evidence from a Driving Simulator Study of Young Drivers authored by Marios Sekadakis, Theofanis Mitsis, Thodoris Garefalakis and George Yannis has been published in Theoretical and Applied Ergonomics. This Paper investigates the relationship between cardiorespiratory fitness and driving behaviour in a highway environment using a driving simulator, with 46 young drivers aged 19 to 27 classified into high-fitness and low-fitness groups based on estimated maximum oxygen consumption, and each participant completing three simulated highway driving scenarios under varying traffic and lighting conditions. The findings suggest that higher physical fitness is associated with greater adaptability in driving behaviour, reflected in increased headway distance variability and slightly higher driving speeds, while high-fitness drivers also exhibited longer time to collision, suggesting improved anticipation and more effective management of traffic conditions. Moreover, environmental factors, particularly traffic volume and lighting conditions, remained the dominant influences on driving behaviour overall. Overall, the Study highlights the importance of considering health-related factors in road safety research and offers insights for developing preventive strategies targeting young drivers.
A paper titled Crash risk factors in the evolution from conventional to fully automated vehicles in urban environments authored by Maria Oikonomou and George Yannis has been published in Case Studies on Transport Policy. This Paper investigates the evolution of crash risk in urban road networks as the market penetration of Autonomous Vehicles (AVs) increases across different levels of automation, using microscopic traffic simulations in a dense metropolitan area of Athens, Greece. The Study integrates conventional vehicles, partially automated (SAE Level 2-3), fully automated (SAE Level 4-5) and aggressively behaving AVs across 15 progressive deployment scenarios, employing an XGBoost machine learning model combined with SHAP explainability to identify the most influential traffic and behavioural features associated with crash risk. The findings suggest that automation influences crash risk in a way that is neither uniform nor isolated, with fully automated vehicles reducing crash risk as their share grows, while partially automated vehicles slightly increase it in mixed-traffic conditions. Aggressively behaving AVs were found to have minimal impact, mostly at high penetration rates, while traffic density, stop sign-controlled sections and queue length emerged as the most influential factors overall. These findings underscore the need for network-specific planning and offer guidance for AV deployment, infrastructure upgrades and regulatory frameworks to support a safer transition to automated mobility.
The Horizon 2020 research project PHOEBE has recently released the PHOEBE 8th Newsletter, which provides information on the latest outcomes of the EU-funded ‘Predictive Approaches for Safer Urban Environment’ (PHOEBE) project aiming to increase the road safety of vulnerable road users, especially those who use active mobility and e-scooters. This version of the Newsletter marks the conclusion of PHOEBE, highlighting that the project’s Final Workshop took place on 23 June 2026 as part of the 10th Road Safety & Simulation International Conference (RSS2026) in Naples, where PHOEBE partners presented the project’s modelling results, including mode-choice modelling, behavioural modelling and the integration of the iRAP and Aimsun tools.
A paper titled Impacts of different feedback features on driver behaviour: Findings from a multiphase naturalistic study authored by Armira Kontaxi, Apostolos Ziakopoulos and George Yannis has been published in Transportation Research Part F: Psychology and Behaviour. This Paper examines the impact of driver feedback delivered through a smartphone application on driving behaviour risk indicators, within a 21-month multiphase naturalistic driving experiment involving 175 car drivers. The Study combines a preliminary analysis using summary statistics and the Wilcoxon signed-rank test with Structural Equation Models on a dataset of 73,869 trips, to assess how feedback mechanisms and exposure factors influence driving behaviours. The findings suggest that the examined feedback mechanisms are effective in reducing the percentage of speeding time and harsh braking events, with the scorecard feature having the highest positive effect on driving habits, followed by gamification through competition and challenges. Furthermore, driving during the morning peak was associated with more unsafe behaviour such as speeding and harsh accelerations, while strong positive correlations were found between speeding, harsh braking and harsh accelerations, highlighting the interconnected nature of risky driving behaviours.

The Editorial for the Special Issue Emerging Solutions and Technologies for Smart Mobility and Vehicle Safety in Transportation authored by Eva Michelaraki and George Yannis has been published in Vehicles. This Special Issue was conceived to explore how emerging technologies contribute to safer, more efficient and more sustainable transportation systems. Particular attention is given to AI-driven decision-making, advanced driver-assistance systems (ADAS), intelligent transportation systems (ITS), vehicle-to-everything (V2X) communication, connected and autonomous vehicles, and data-centric approaches to traffic safety and mobility management. The papers published in this Issue reflect the multidisciplinary nature of modern transportation research, addressing topics such as driver behaviour analysis, crash prediction and prevention, automated driving, adaptive traffic management, smart infrastructure, and predictive analytics. Although diverse in their specific application domains, these contributions collectively demonstrate that the future of transportation safety and smart mobility will be shaped by the convergence of artificial intelligence, connectivity, automation, human-centred design, and evidence-based operational strategies.
The European Road Safety Charter of the European Commission recently published an article titled “Reduce speed to save lives” highlighting that an estimated 10% to 15% of all road crashes and as much as 30% of fatal crashes are directly linked to speeding. The article underlines that speed not only increases the likelihood of a crash but also makes its consequences far more severe for vulnerable road users: when a pedestrian is struck by a car at 30 km/h, their chance of survival is about 90%, while at 50 km/h this drops drastically to approximately 20%. Scientific evidence shows that implementing a city-wide 30 km/h speed limit can reduce fatalities by an average of 37%, while also contributing to an 18% reduction in emissions, a 2.5 dB decrease in noise pollution and a 7% reduction in fuel consumption, with minimal impact on travel times.
