A Paper titled “Comprehensive Assessment of Driver Takeover Readiness via a Multimodal Fusion Multi-Task Learning Model” has been published in Advanced Engineering Informatics authored by Hanwen Deng, Shuxiang Lin, Chaojie Fan, Xianhui Wu, Kui Wang, Yong Peng and George Yannis. This Paper constructs a multimodal takeover readiness dataset that incorporates visual, physiological, gaze, and demographic features. The dataset was collected from 32 participants using a within-subject design, yielding a total of 20,160 s of synchronized multimodal time-series data. Furthermore, post-trial self-reported questionnaire scores were used as the ground-truth labels for takeover readiness. The experimental results demonstrate that the proposed model effectively fuses multimodal features and captures task-specific representations, achieving an average Accuracy of 79.0%, Balanced Accuracy of 78.5%, and Macro F1 score of 78.2% across five 5-class classification tasks, outperforming the selected baselines. These findings provide insights for the development of more precise and adaptive intervention strategies in future automated driving systems. 

A paper titled “Literature review of legal frameworks and liability allocation in connected and automated vehicles” authored by Julia Roussou, Apostolos Ziakopoulos, Armira Kontaxi and George Yannis has been published in Research in Transportation Business & Management. The objective of this Paper is to provide a comprehensive review of current literature in order to identify critical knowledge gaps especially in the design of robust legal frameworks and clarify the impacts of liability allocation regimes on CAVs adoption and operation. By addressing these issues, the paper aims to guide interested stakeholders such as, policymakers, researchers and industry leaders in shaping a transition to automated mobility that is not only safer and more efficient, but is also supported by clear, effective, and trustworthy legal frameworks. 

A paper titled “Evaluating Risky Driving Behavior Using a Naturalistic Driving Dataset: A Hybrid Modelling Approach” authored by Elena Maria Theodoraki, Thodoris Garefalakis, Eva Michelaraki and George Yannis has been published in Infrastructures. This Paper develops and evaluates three hybrid machine learning models: (i) Deep Neural Network–Random Forest (DNN-RF), (ii) Convolutional Neural Network–Long Short-Term Memory (CNN-LSTM), and (iii) Recurrent Neural Network–AdaBoost (RNN-AdaBoost), to classify risky driving behavior into three safety levels using naturalistic driving data from Belgium and the UK. The dataset includes 69 drivers, 15,389 trips, and 265,512 min of driving data. Furthermore, feature importance analysis identified harsh acceleration and braking as the most critical factors in Belgium, while total trip distance and harsh acceleration were predominant in the UK. The findings support the potential of hybrid deep learning models in improving road safety by accurately detecting risky driving behaviors. These insights can inform targeted interventions and driver assistance technologies to mitigate crash risks and promote safer driving practices.  

A paper titled “Implementation of an integrated model for understanding the impact of task complexity and coping capacity on crash risk” authored by Eva Michelaraki and George Yannis has been published in Accident Analysis & Prevention. This Study aims to identify the interaction of road, vehicle and driver-related factors to the estimation of task complexity, coping capacity and risk. To this end, data from a naturalistic driving experiment involving 135 drivers and 31,954 trips collected over a four-month period were analysed across experimental phases incorporating real-time and post-trip interventions. The results showed that environmental factors, including time of day, weather, distance and duration, were positively associated with task complexity and increased crash risk. Driver-related and vehicle-related state factors influenced coping capacity, which was generally negatively associated with risk. Overall, the Paper highlights the potential of data-driven interventions to improve road safety and support more effective driver assistance systems.  

The NTUA Road Safety Observatory (NRSO) has launched its new Road Safety Data Warehouse with highly interactive dashboards, now available and open to all to explore. Thirty interactive dashboards bring together road crash statistics, risk exposure, safety performance indicators, self-reported behaviour and other contextual data, in a comprehensive way for Greece, the European Union and Worldwide. A wide array of data sources was exploited, and concise multi-level data processing was carried out. For Greece, ten dashboards cover six decades of road crashes and casualties, from long-term trends to the most recent monthly data, broken down by region and type of crash, user, road and vehicle. Further dashboards cover risk exposure, safety performance indicators and self-declared behaviour. At EU level, eight dashboards exploit CARE data across all EU Member States, comparing overall trends with risk exposure, detailed fatality characteristics, safety performance indicators and self-declared behaviour. Worldwide, twelve dashboards exploit data from WHO Global Status Reports on Road Safety, covering fatality data, safety performance indicators, other contextual data (national strategy, legislation, infrastructure, vehicle post-crash care) and self-declared behaviour. All 30 dashboards are regularly updated at the NRSO Data page, as new official data is released.

The Horizon Europe research project IMPROVA has recently released its 4th Newsletter, focusing on enhancing road safety by addressing the complexities of long-term consequences (LTC) caused by road traffic crashes.

The United Nations and the World Health Organization (WHO) organized with great success a two-day High-Level Meeting on Improving Global Road Safety which was held in New York, on 20-21 July 2026, under the theme “Scaling up and accelerating implementation of commitments to halving road traffic deaths and injuries by 2030“. In this context, the 104th UN General Assembly has adopted the “Progress Declaration on Global Road Safety“, reaffirming the global target of reducing road traffic deaths and injuries by at least 50% by 2030. Furthermore, Governments committed to undertake various actions, such as establishing or designating a national lead agency or equivalent entity to coordinate road safety across government. The Declaration also highlighted the need to ensure that public road transport systems, including bus rapid transit and similar systems, are the safest road transport mode, being also affordable, accessible and inclusive, including for children, older persons and persons with disabilities.  

The European Commission, in line with the EU’s General Safety Regulation, recently announced new mandatory life-saving systems for all new passenger cars and vans registered across the EU, starting on 7 July 2026. These new systems include an advanced emergency brake detecting pedestrians and cyclists, a driver distraction warning system, better forward vision, new tests for worn tyres, and an expanded safety glass area to protect pedestrians in accidents. These requirements support the EU’s long-term Vision Zero goal of near-zero road fatalities by 2050, while helping to better protect vulnerable road users and encourage wider adoption of advanced driver-assistance systems.  

The Directorate General for Mobility and Transport (DG Move) of the European Commission recently published its implementation strategy for its Directives to modernize EU rules on driving licences and driving disqualifications with the active contribution of NTUA. These initiatives aim to increase road safety across the EU, reducing the number of road deaths as well as undue administrative burden on citizens and authorities. The measures include an EU-wide accompanied driving scheme for 17-year-old drivers, a probationary period for novice drivers, and more systematic checks of people’s fitness to drive. The new rules also adjust training and testing requirements and set out key steps for the introduction of mobile EU driving licences and the EU-wide recognition of driving disqualifications, ensuring drivers who commit serious offences are held accountable across the EU.  

The European Road Safety Charter of the European Commission has announced the finalists for its Excellence in Road Safety Awards 2026, as a part of the EU Road Safety Conference which will take place on 23 November 2026 in Brussels, recognizing inspiring initiatives from Charter members across Europe that advance road safety through smart infrastructure, real-time data, immersive training and child-friendly streets. Fifteen finalists were selected across five categories: At Work, Education, Technology, Urban, and Vulnerable Road Users. The winners will be announced at a ceremony during the Event.  

The Directorate General for Mobility and Transport (DG Move) of the European Commission recently adopted an Implementing Regulation establishing a common set of urban mobility indicators to be applied across the European Union. This Implementing Regulation mandates Member States to collect policy-relevant data on urban mobility, helping cities, Member States and EU institutions to monitor developments on the basis of reliable data. It covers key dimensions of urban mobility, including sustainability, safety and accessibility. This adoption marks an important step in strengthening the evidence base for urban mobility policy in the EU. Better data will support better decisions, enabling public authorities at all levels to plan and invest more effectively in sustainable urban transport. 

The PHOEBE Decision Support Tool (DST) is now available through the PHOEBE Dashboard. Developed within the Horizon Europe PHOEBE project, the platform enables practitioners, researchers and decision-makers to assess and compare the impacts of road safety interventions using evidence from real-world European pilot cases. Users can explore safety, mobility and environmental performance indicators, Impact Modification Factors (IMFs), and supporting statistical evidence to evaluate different intervention scenarios. The dashboard supports transparent, data-driven decision-making towards safer and more sustainable transport systems. 

The United Nations Road Safety Fund (UNRSF), has recently launched the UN Road Safety Lab, a new Knowledge Hub and AI-enabled knowledge platform for road safety. Established in 2018, UNRSF brings together 21 UN member organizations, governments, the World Bank, the private sector and civil society under a single coordinated framework, mobilizing resources and driving system-level road safety reforms in low- and middle-income countries. The new Lab is hosted by the United Nations Institute for Training and Research (UNITAR), the training and capacity-development arm of the UN, and organizes its content across four core areas: Knowledge Products, Platforms of Engagement, Learning, and AI-Enabled Knowledge Solutions, alongside an interactive map showcasing the countries where the Fund is active. 

The World Health Organization (WHO) recently released new road death data, showcasing that despite the addition of more than one billion motor-vehicles to the world’s roads, road traffic deaths declined by 21% between 2011 and 2025. With nearly 60% of the world’s population now living in urban areas, growing demand for mobility threatens to overwhelm transport systems that were largely designed around private motor vehicles. This data show that across the world, 10 countries reduced road deaths by 50% in the decade to 2021 and more than half of all countries reported falling fatalities in that period. Yet progress is uneven, with 36% drop in deaths in the WHO European Region, a 15% drop in the Western Pacific Region, a 2% drop in the WHO South-East Asian Region, no change in rates in the Americas and a 17% rise in deaths in the WHO African Region. 

The European Road Safety Charter of the European Commission recently published an article titled “Road infrastructure: A foundation for safer roads“, highlighting the critical role of road infrastructure in achieving safer roads. Road design can either support safe behavior or create danger. Many roads encourage high speeds without adequate protection, increasing crash severity. Undivided roads raise head‑on collision risks, unsafe roadsides worsen run‑off crashes, and missing footpaths or crossings leave vulnerable users exposed. To create self-explaining and forgiving roads, six core design principles guide safer infrastructure: provide orientation by making the road environment easy to read and anticipate; attract attention through clear design and signs highlighting hazards; promote standardization with consistent layouts that help users recognize situations; support the detection of potential conflicts through good visibility and guidance at critical points; improve clarity with visible and easy to interpret signs and markings and provide passive safety through forgiving roadsides and designs that reduce injury severity. 

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.”
