The European Transport Safety Council (ETSC) has published the 48th PIN Flash Report titled “Tapping the potential for reducing work-related road deaths and injuries“. This Report examines how governments, Authorities and employers are addressing the issue of work-related road deaths, identifies examples of good practice and highlights remaining gaps. Specifically, data from 16 European countries show that work-related road deaths account for 30-40% of all road deaths, but the official numbers are distorted by inconsistent reporting, missing data and incompatible national definitions. The findings underscore the need for closer alignment between road safety and Occupational Safety and Health (OSH) systems, stronger data integration and clearer accountability for road risk management at every level.   

A global coalition of partners announced their commitment to the Implementation of the United Nations Decade of Sustainable Transport 2026-2035, to accelerate the transition towards inclusive, safe, green and efficient road systems for all. More precisely, IRF, Arup, NTRO, Global Alliance of NGOs for Road Safety, FIDIC, iRAP, ORIS and World Wildlife Fund joined forces to translate the vision of the Decade into concrete action by providing strategic direction and practical support for those who plan, build and manage road systems. At its core stands the Roadmaps for Change series will outline policy actions, technical standards and tools, replicable practices, innovation and indicators of progress, together with a capacity-building programme for trainings and peer-learning activities, with a special focus on road and transport public Authorities.  

A paper titled State-of-the-art review on sustainable driving behavior: trade-offs between road safety, fuel consumption and emissions authored by Virginia Petraki, Apostolos Ziakopoulos and George Yannis has been published in Accident Analysis & Prevention. This paper aims to systematically review the role of driving behavior, as expressed by road crashes, fuel consumption, and vehicular emissions. A two-stage PRISMA approach was developed to shortlist the most relevant studies for systematic review out of 1,120 initial studies, with each stage focused on safety and eco-driving behavior studies. The findings suggest that the main driver behavior factors found to affect both road crashes and fuel consumption/emissions are related to average and instantaneous driving speed and acceleration, harsh acceleration and deceleration events, driving volatility, vehicular jerk, and idling during driving. Furthermore, a discussion of the knowledge gaps in the potential of an integrated methodological framework of driving behavior assessment in the context of road safety, economy, and environmental sustainability is then provided, followed by the relevant conclusions.

Its purpose was to synthesise these findings, benchmark capability gaps, and ultimately deliver a framework and practical toolkit. The design integrated a systematic literature review, a global survey, semi-structured interviews and a detailed analysis indicating a clear set of strategic actions necessary to mature global practice. 

A paper titled Evaluating driver preferences between punitive and non-punitive speeding penalties: Results from a stated choice experiment authored by Athanasios Theofilatos, Apostolos Ziakopoulos, Evangelia Stratigi, Pantelis Kopelias and Dimitris Potoglou has been published in Journal of Safety Research. This Paper aims to investigate driver preferences regarding penalties for speeding violations in Greece: (Option A) immediate fines with off-road short detention (administrative process); (Option B) attendance of compulsory road safety seminars; and (Option C) judicial processes with possible dispute of fines in court. Data were collected via a Stated Choice (SC) survey conducted during June and July 2023 in Greece, involving 161 participants resulting in 805 choice situations, and were analyzed by utilizing a random parameter multinomial logit model to capture unobserved heterogeneity among drivers. The results showed that only 4.6% of respondents preferred the judicial process, indicating a strong deterrent effect of potential trial and associated costs. These findings point towards more effective enforcement strategies while balancing penalty costs and duration of compulsory off-road detention and promoting educational-related non-punitive measures. 

A paper titled Cross-cultural perspectives of vulnerable road user safety performance based on evidence from 39 countries authored by George Yannis, Apostolos Ziakopoulos, Dimitrios Nikolaou, Konstantinos Kaselouris, Mette Møller, Dagmara Jankowska-Karpa and Marie-Axelle Granié has been published in IATSS Research. This paper aims to provide a quantified update on VRUs safety performance by analyzing data from a broad-country sample. For this study, data was utilized from the third edition of the E-Survey on Road Users’ Attitudes (ESRA3) survey, which was conducted in 2023, covering 39 countries from 5 continents. A statistical analysis based on Self-Organizing Maps (SOMs) and clustering was conducted to meaningfully categorize VRU groups, enabling the quantification of each category and providing scientific documentation for more informed policymaking. Findings include the fact that VRU safety perceptions and behaviors differ significantly across regions, with Europeans feeling safer overall, with older VRUs displaying fewer risky habits than younger ones. Cyclists often neglect helmet use in particular countries (Thailand, Bosnia), while drug and alcohol consumption while riding is notably high in specific countries as well (Ireland, Thailand, the Netherlands). Furthermore, for all VRU modes, statistical tests revealed that there is a statistically significant association between younger individuals and higher-risk cluster categorization. Finally, the paper provides recommendations for road safety stakeholders operating at different levels, which could be implemented in efforts to enhance VRUs road safety. 

A paper titled Analyzing SHAP values of XGBoost algorithms to understand driving features affecting take-over time from vehicle alert to driver action authored by Marios Sekadakis, Thodoris Garefalakis, Peter Moertl and George Yannis has been published in Displays. This Study investigates the factors influencing Take-Over Time (TOT) during transitions from automated to manual driving, emphasizing the novelty of applying XGBoost modeling combined with SHAP analysis to uncover non-linear and implicit dependencies between features. Driving simulation data were utilized as key variables for the analysis. The findings indicate that higher automation levels resulted in longer TOT, with SHAP values consistently positive for AD Level 3, demonstrating the added value of explainable machine learning in clarifying these patterns. Furthermore, Dynamic driving parameters, such as deceleration and speed variability, were also significant. Moreover strong negative deceleration values were generally associated with shorter TOT, reflecting quicker responses under urgent braking. Speed showed a moderate positive effect on TOT at 80–110 km/h, with drivers taking additional time to assess the environment, but higher speeds (above 110 km/h) resulted in quicker responses. By combining methodological innovation with contextual insights, this study contributes to a deeper understanding of takeover behavior and provides actionable evidence for optimizing adaptive HMI design and takeover strategies in AD systems. 

A paper titled In full-touch HMI mode: How does car-following pressure, task complexity, and speed affect driver’s visual distraction characteristics? authored by Kunchen Li, Menglu Gu, Wei Yuan, Yisi Lu and George Yannis has been published in Accident Analysis & Prevention. This paper aims to investigate the effects of interaction tasks and traffic situations on drivers’ visual distraction characteristics in full-touch HMI mode. A total of 50 distinct participants were recruited: 30 took part in a real-road experiment, and 30 participated in a driving simulator experiment. Ten participants took part in both experiments, contributing to a total of 60 participant-sessions. Air volume control, temperature control, and call a contact are selected as typical tasks in each experiment. The results show that the mean off-road glance duration is influenced by the car-following pressure but not by the task. The mean glance duration is lower when the driver is following a vehicle, with an average decrease of 21.3%. Furthermore, higher speeds lead to a decrease in the total off-road glance duration, where participants tend to reduce the duration of each off-road glance while increasing the number of glances to compensate for the increased risk. The findings  can differentiate the visual demands of various HMI tasks and clarify how drivers adapt their gaze behaviors as driving demands change (e.g., car-following pressure), offering safety-related recommendations for drivers. 

A paper titled Infrastructure use and related safety feeling of different road user types globally authored by George Yannis, Dimitrios Nikolaou, Konstantinos Kaselouris and Gerald Furian has been published in IATSS Research. The objective of this Paper is to investigate trends in road infrastructure usage and safety perceptions among car drivers and vulnerable road users across different types of roads worldwide. For this study, data from the third edition of the E-Survey on Road Users’ Attitudes (ESRA3), conducted in 2023 and covering 39 countries from 5 continents, were utilized. The results revealed that car drivers in Europe have the highest usage of inter-city motorways, while America leads in using thoroughfares and high-speed roads within cities. Moreover, in Europe, rural roads and roads connecting towns and villages are heavily utilized. Furthermore, moderate to weak linear relationships were discovered between the perceived safety of road infrastructure and road fatality rates, as well as between the perceived safety of road infrastructure and Gross Domestic Product. Lastly, recommendations for enhancing infrastructure safety, such as road maintenance and upgrades, are provided. 

A NTUA Diploma Thesis titled “Driving Behavior Analysis Using Connected Vehicle Data” was recently presented by Andreas Englezos. For the purposes of this research, variables related to speed, engine temperature, the anti-lock braking system (ABS), and other driving characteristics were examined. The data were collected over a three-month period to identify different route profiles in terms of driver behavior. From the application of the algorithm, it was found that the variable with the highest importance value was the engine oil temperature. Finally, a Binary Logistic Regression was performed to examine the extent to which the independent variables influence the probability of ABS activation, which showed that the variable with the greatest influence was engine activation.  

Together for Safer Roads Global Coalition recently published a Report titled Optimizing Fleets with Telematics presenting key insights on how vehicle telematics can transform fleet safety and reduce crash risks through data-driven interventions.
