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. 
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.

At a recent podcast in Break It Down, NTUA Professor George Yannis discusses how the traffic system works, congestion, private cars and public transport. The discussion highlighted that congestion is the norm in modern cities and that improving mobility requires better alternatives to private cars, including faster buses, expanded metro networks, cycling and walking. Special emphasis was given to traffic management, bus lane enforcement, the implementation of 30 km/h speed limits and the role of education and enforcement in changing road safety culture. The discussion also highlighted that the significant reduction in road fatalities in Greece during 2025 demonstrates that consistent enforcement can save lives. Full article and related video-podcast are now available.
