The Horizon Europe research project metaCCAZE has recently released the metaCCAZE 3rd Newsletter, which provides information on the latest outcomes of the EU-funded metaCCAZE project aiming to accelerate the deployment of smart systems that combine electric, automated and connected technologies and infrastructure, enabling zero-emission shared mobility services for both passengers and goods in European cities. This version of the Newsletter celebrates the 2^nd year of the EU-funded project, marking a key turning point: the spotlight is now equally on the Follower Cities—Athens, Gozo, Kraków, Milan, Miskolc, and Poissy in Yvelines, part of the Paris Region. Each city brings its own challenges, priorities, and ambitions—from Milan’s suburban e-pod mobility concept to Gozo’s autonomous shuttle, and Athens’ integration of electric buses using AI-supported planning. The diversity across these urban environments provides a proving ground for scalable, people-centred mobility solutions. 

The Directorate General for Mobility and Transport (DG Move) of the European Commission recently published a Report to address the critical need for Safe and Secure Parking Areas (SSPAs) for professional drivers across the European Union, focusing on their availability, security standards, and development potential. This Report highlights persistent challenges in the road transport sector, including driver shortages, inadequate parking infrastructure, and security concerns, which hinder the sector’s operational efficiency and driver well-being. To address this issue, the Study recommends strategic investments, including the rapid upgrade and certification of existing parking areas that already meet the required safety and security standards. Furthermore, this Report highlights that improved connectivity and digitalisation are essential drivers for making SSPAs more accessible and attractive.  

The Directorate General for Mobility and Transport (DG Move) of the European Commission announced updated rules for safer roads, less air pollution and digital vehicle documents. The new rules will take into account the growing presence of electric vehicles and adapt to emerging technologies. They will introduce enhanced inspections, including periodic technical inspections for electric vehicles and advanced driver-assistance systems, annual inspections for older cars and vans, and advanced emission testing methods to detect high-emitting vehicles to reduce fine particles pollution. The proposed changes reflect the EU’s commitment to safe and sustainable mobility while ensuring the free movement of people and goods. Between 2026 and 2050, it is estimated that these proposals will save around 7,000 lives and prevent around 65,000 serious injuries.

A paper titled Investigation of hit-and-run crash severity through explainable machine learning authored by Stella Roussou, Apostolos Ziakopoulos and George Yannis, has been published in Transportation Letters. This study, uses a 5-year dataset from Victoria, Australia and analyzed with CatBoost algorithms and SHAP values using explainable machine learning techniques, to highlight key severity factors. Findings suggest that the presence of police at the crash scene emerges as the most critical determinant, underscoring the importance of law enforcement in mitigating severe crash outcomes. Furthermore crashes involving passenger vehicles and those on weekends were also linked to higher severity. These novel findings offer valuable insights for targeted interventions and policy-making to mitigate the impact of severe hit-and-run crashes and enhance road safety. 

A paper titled Analyzing the safety effects of different operating speeds for an autonomous shuttle bus service authored by Maria Oikonomou, Marios Sekadakis, Christos Katrakazas and George Yannis has been published in Traffic Safety Research. This study utilizes microscopic simulation analysis in order to quantify the impact of road safety of an automated shuttle bus service within traffic. In the traffic network of Villaverde, Madrid, several scenarios were simulated using the Aimsun software considering the various CAV MPRs and the different operational speeds of the service, namely 15, 30, and 45 km/h. The analysis revealed that the conflict frequency is lower when the shuttle bus operates at 45 or 30 km/h compared to 15 km/h, with the 45 km/h speed showing the largest reduction. This reduction in conflicts is probably due to the shuttle bus adapting more easily to the average traffic speed and is more synchronized with traffic flow. The current study establishes a solid relationship for the conflict frequency of AV shuttles enabling stakeholders to optimize road safety towards a future of automated traffic. 

The European Association of Motorcycle Manufacturers (ACEM) together with the Fédération Internationale de Motocyclisme (FIM) have launched “Learn – Ride – Enjoy – Repeat”, a European-wide Campaign designed to encourage novice and experienced riders to take high-quality voluntary motorcycle training. This Campaign aims to inspire European riders to take the next step in their journey by enrolling in certified training programmes, ensuring more riders have access to advanced tools and knowledge to enjoy motorcycling safely and responsibly. The Campaign builds on the success of the European Motorcycle Training Quality Label – voluntary certification of high-quality post-license training courses across Europe. As motorcycling continues to serve as a key mobility and leisure tool for millions across Europe, improving rider safety remains a top priority.  

The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Traffic Safety Culture Thematic Report which emphasizes on growing a positive Traffic Safety Culture (TSC). This Thematic Report highlights that TSC encompasses shared values, norms, and attitudes that impact behaviours across the road system, influencing not only individual road users but also key stakeholders such as public authorities, private companies, NGOs, vehicle manufacturers, and infrastructure designers. An important way to leverage TSC as a concept to improve road safety is through organisations and companies, also preventive efforts to tackle risk behaviours should be made, ideally by focusing on long-term behavioural change.  

The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Professional Drivers Thematic Report which mainly refers to the safety of heavy goods vehicles (HGVs) and buses. This Thematic Report highlights that the safety of HGVs and buses are significantly influenced by road infrastructure due to their unique characteristics such as mass, maneuverability, and acceleration/deceleration capabilities, as well as the fatigue and distraction of the drivers. Furthermore, countermeasures about separating these heavy vehicles from other road users, providing professional drivers with timely warnings about hazardous or restricted road sections and addressing the need for adequate and well-managed overnight parking facilities for HGVs are suggested.  

The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Children Thematic Report which refers to the safety of children. This Thematic Report highlights that children are, along with elderly people, the most vulnerable road users with boys being most at risk due to greater exposure and risk-taking behaviour. Moreover, a series of specific countermeasures are suggested, such as road infrastructure that prioritizes vulnerable users, 30 km/h zones around childcare facilities, mandatory protective equipment, the enhancement of active and passive vehicle safety, traffic laws with strict penalties, as well as better Traffic Safety and Mobility education in schools.  

The European Commission published collision matrices of fatalities in the EU by road user and area type (urban, rural, total). The available EU-wide data for 2023 contained in the CARE database, demonstrate that 38% of road traffic fatalities occurred in urban areas, with vulnerable road users (pedestrians, cyclists, users of powered two-wheelers and personal mobility devices) representing almost 70% of total fatalities. Furthermore 52% of road traffic fatalities occurred in rural areas, with vulnerable road users (pedestrians, cyclists, e-scooters and users of powered two-wheelers) representing almost 36% of total fatalities. These collision matrices provide highly useful insight on road crash causes, exploited for appropriate EU policies and actions.      

The European Transport Safety Council (ETSC) has published the 48th PIN Flash Report titled “Reducing Serious Injuries on European Roads“. This Report examines the underreporting of serious injuries in European roads. According to official sources, approximately 1,291,000 people are reported injured annually in the European Union, with 141,000 of these injuries being serious. While most serious injuries are suffered as a result of collisions involving motor vehicles and are much more likely to be reported by police, many involving pedestrians and cyclists where no motor vehicle was involved go unreported. The current performance in the European Union is not on track for reaching the target to reduce serious road traffic injuries by 50% between 2020 and 2030 and further action targeting serious injuries reduction is needed.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Annual Statistical Report on Road Safety, April 2025 in the EU, which provides an overview of crash data for 2013 to 2023 from 27 EU Member States and the four EFTA countries. According to this Report, 53% of road traffic fatalities occurred on rural roads, versus 38% in urban areas and 9% on motorways. It was also revealed that car occupants (drivers and passengers) represented 44% of all fatalities, while pedestrians accounted for 18%, users of powered two-wheelers (motorbikes and mopeds) 17%, and cyclists 10%.  

A paper titled Identifying driving profiles after take over request in automated vehicles at SAE levels 2 and 3 authored by Marios Sekadakis, Sandra Trösterer, Peter Moertl and George Yannis has been published in Transportation Research Part F: Traffic Psychology and Behaviour. The analysis included clustering to develop distinct driving profiles based on key measurements collected through a driving simulator experiment, such as acceleration, deceleration, and speed, offering a deep understanding of driver behavior in responses to take over requests. Findings suggest that the nervous driving profile, although less frequent, poses significant safety implications due to higher deceleration rates and variability in speed and deceleration. The study also highlights that non-driving related tasks increase the need for longer take over time with greater variability observed at higher automation levels. These insights can inform the design of more adaptive HMI systems, enhance real-time feedback mechanisms, and improve driver training programs to ensure safer transitions during take over requests. 

A paper titled Evaluating the Environmental and Safety Impacts of Eco-Driving in Urban and Highway Environments authored by Marios Sekadakis, Maria Ioanna Sousouni, Thodoris Garefalakis, Maria Oikonomou, Apostolos Ziakopoulos and George Yannis has been published in Sustainability. Within a group of 39 participants aged 18–30, multiple driving scenarios were conducted, both without and with eco-driving guides, to assess the impact of eco-driving behavior on environmental sustainability and safety outcomes. Data on pollutant emissions, as well as crash probability were utilized using linear regression models, while binary logistic regression models were employed to assess crash probability. The analysis revealed thateco-driving led to a significant reduction in pollutant emissions, with CO₂ emissions decreasing by 1.42%, CO by 98.2%, and NO_x by 20.7% across both urban and highway environments, with a more substantial impact in urban settings due to lower average speeds and smoother driving patterns. These findings support the integration of eco-driving techniques into transportation policies and driver education programs to foster sustainable and safer driving practices. 

A paper titled Examining the effects of texting, web surfing, and navigating apps on urban driving behavior and crash risk authored by Maria Oikonomou, Foteini Orfanou, Marios Sekadakis, Dimosthenis Pavlou and George Yannis has been published in Traffic Safety Research. This study collects driving data from 36 young adult drivers through a driving simulator experiment, supplemented by a survey to gather participant characteristics and driving profiles. Data analysis utilized linear and binary logistic mixed models to explore the effects of texting and web surfing on speed and its deviation, headway distance and its deviation, and crash risk. Results indicate that using texting, web surfing and navigating applications while driving elevate crash risk by 10% and decrease speed, speed deviation, headway, and headway deviation by 9%, 23%, 6%, and 18%, respectively. These findings underscore the crucial role of specific smartphone applications in shaping driving behavior and emphasize the need for targeted interventions to mitigate the associated risks in urban driving scenarios. 

The Horizon Europe research project IMPROVA has recently released its 2nd Newsletter, focusing on enhancing road safety by addressing the complexities of long-term consequences (LTC) caused by road traffic crashes. This newsletter announces the 2nd Knowledgebase Forum (KBF) which will focus on the advancements in the topic of Long-term con sequences: Scales, Virtual Testing and Human Body Models, which will take place in Vilnius Lithuania, on September 8 2025.

A paper titled Using computer vision and street-level videos for pedestrian-vehicle tracking and behaviour analysis, authored by Roberto Ventura, Stella Roussou, Apostolos Ziakopoulos, Benedetto Barabino and George Yannis has been published in Transportation Research Interdisciplinary Perspectives. Using advanced computer vision object detection and feature extraction models, this framework integrates Kalman filtering, homography transformations, and object re-identification to achieve high accuracy. This study utilizes data from roadside video recordings from Athens, Greece. The findings show accuracy rates of 50%-70% in detecting traffic light statuses and identified a 23% discrepancy on average between manual and automated counts of illegal crossings. This paper underscores the potential of computer vision detection systems to provide reliable, real-time data that takes the road network conditions into account, ultimately contributing to safer urban traffic management and informed policy decisions. 

The Directorate General for Mobility and Transport (DG Move) of the European Commission announced a reinforced platform for dialogue and co-creation of actions to implement the 2021 EU Urban Mobility Framework.  The Expert Group for Urban Mobility, released 17 new Reports on mobility and road safety, reaffirming the EU’s long-term strategic goal to achieve as close to zero deaths and zero serious injuries on the EU’s roads by 2050. The goal is stronger engagement by Member States and improved dialogue with cities, regions and stakeholders on all urban mobility issues. 

The European Road Safety Charter of the European Commission, has recently published a new Article, exploiting the latest statistics from across Europe for helmet use and seatbelt/child restraint systems, two of the most widespread safety equipment. Through this article, the Chapter increases the attention over the coming months to the use of safety equipment, hoping to achieve the EU’s objective of halving the number of road deaths by 2030. The data suggests that when cycling, helmet use reduces the risk of serious head injury by 60% and fatal head injury by 71%, also according to the WHO, wearing a quality motorbike helmet reduces the risk of death by over six times and the risk of brain injury by up to 74%. Wearing a seatbelt reduces the risk of death and injury by around 60% for drivers and 44% for rear-seat passengers. Correct use of a child restraint system reduces the risk of being killed or injured by around 55% to 60% compared with children who are not buckled up. 

The European Road Safety Charter of the European Commission, has recently published a Guide on how to run effective road safety awareness campaigns, highlighting their role in improving road safety, including in urban areas. The Guide provides practical advice on how to design, implement, and evaluate such campaigns to enhance road safety efforts, including examples of campaigns from cities across Europe. These initiatives aim to inform, persuade, and encourage individuals to adopt safer behaviours on the road.  

The Institution of Engineering and Technology (IET) has recently published a book edited by Aliaksei Laureshyn, Niels Agerholm and Matúš Šucha, titled “Traffic Safety Data: Sources, analysis and applications”. It examines the different data types that can be collected and used for monitoring, analysing, and improving road safety, including chapters on police records and accident modelling, healthcare system records, self-reporting of accidents, data from insurance companies, and more. This book provides a wide and up-to-date perspective on relevant traffic safety data, helping to broaden the horizons for safety experts and also to promote a more knowledge and data based approach to traffic safety management. 

The International Transport Forum (ITF) together with the World Health Organization (WHO), recently launched “The Global Road Safety Assessment Framework for Corporate Action and Reporting” to support businesses in integrating robust road safety practices into their operations and value chains and thereby contribute to the global effort to reduce road traffic fatalities and injuries. The development of this Framework was initiated in response to a call from Transport Ministers representing over 60 countries to enhance road safety practices across corporate value chains and align them with the Global Plan for the United Nations Decade of Action for Road Safety 2021-2030, by incorporating key standards and guidelines. 

UNRSF at the 4th Global Ministerial Conference on Road Safety, which was held at Morocco, Marrakesh on 18-20 February,  reaffirmed their commitment to making roads safer. This event mobilised critical funding to support life-saving road safety initiatives in over 125 low and middle income countries facing the highest road crash fatalities. In line with its mission to drive systemic changes in road safety, the UNRSF announced eight new projects, tackling key road safety challenges, from strengthening motorcycle safety laws and sustainable financing to improving enforcement and protecting vulnerable road users. 

The International Transport Forum (ITF) has recently published its new Safe System Tool, with the active contribution of NTUA, which offers a user-friendly interface to navigate through the International Transport Forum’s framework for implementing a Safe System. The Tool helps road safety stakeholders to evaluate how their strategies, projects or plans contribute to a Safe System, since it visualises opportunities for improvement and helps to identify effective interventions to save lives. 

Armira Kontaxi has successfully defended her PhD dissertation titled: The Driver Behavior Telematics Feedback Mechanism, under the supervision of NTUA Prof. George Yannis. Data from a 21-month naturalistic driving experiment involving 230 drivers across six feedback phases generated a robust dataset of 106,776 trips, covering 1.3 million kilometers. Advanced statistical and machine learning models, including Generalized Linear Mixed-Effects Models (GLMMs), Structural Equation Models (SEMs), and Survival Analysis methods (e.g., Weibull AFT, Cox-PH with frailty, and Random Survival Forests), were utilized to analyze behavioral metrics such as speeding, mobile phone use, harsh braking, and accelerations which demonstrated substantial impacts on reducing risky behaviors. Key findings suggest that the overall impact of feedback significantly improved driving behavior and safety, with notable variations across user groups and driving contexts. Urban environments demonstrated the most substantial reductions in mobile phone use and harsh events, likely driven by the heightened complexity and demands of navigating urban settings. These findings highlight the need for continuous and adaptive engagement strategies, incorporating diverse features tailored to the specific needs of different user groups and driving contexts, to ensure long-term effectiveness and sustained safety improvements.     

The Global Alliance of NGOs for Road Safety recently published a White Paper based on global best practices, in consultation with Alliance member NGOs, ensuring safe motorcycle helmets through appropriate laws, enforcement, and promotion. Through this White Paper, the Global Alliance of NGOs for Road Safety and its over 395 member NGOs from more than 100 countries, will assist Governments achieve the reduction of road fatalities and injuries needed to accomplish the vision of having zero road deaths and injuries by 2030.  

The Horizon Europe research project metaCCAZE has recently released a new Blog Post authored by Evi Koliou on AI and Smart Cities. As stated, AI-driven solutions can transform urban environments, since smart traffic control systems are no longer a futuristic concept but a present reality. These AI-driven systems optimise traffic flow, reduce congestion, and cut down emissions. By leveraging connected vehicle data and digital twins—technology that simulates real-world scenarios—we can develop road safety strategies that save lives. 

The Y-Mobility latest Conversations in the Park podcast episode “Speed Kills: Is Our ‘Freedom to Drive’ a Danger to Others?” explores the contentious relationship between personal driving freedom and public safety with three global experts in transportation safety and technology willing to say what others won’t: George Yannis, Nick Reed and David Fidalgo, hosted by Timothy Papandreou. Quick reality check:

• More road deaths than all wars combined
• Your SUV? It’s part of the problem
• That 30 km/h limit you hate? It’s saving lives
• Your “excellent driving skills”? That’s part of the problem too

Controversial? Good. That’s the point. 🤔 Genuine question: When did we decide that driving fast was a right rather than a privilege? The related audio-podcast is now available:    

A paper titled Understanding the effects of underreporting on injury severity estimation of single-vehicle motorcycle crashes: A hybrid approach incorporating majority class oversampling and random parameters with heterogeneity-in-means authored by Nawaf Alnawmasi, Apostolos Ziakopoulos, Athanasios Theofilatos and Yasir Ali  has been published in Analytic Methods in Accident Research. This study aims to provide an empirical assessment of the impact of underreporting issue using a hybrid approach in estimating injury severity for single-vehicle motorcycle crashes. Key results suggest that crashes occurring during slowing down or stopping are associated with lower injury severity, whereas negotiating a right turn increases the probability of severe injuries. Interestingly, crashes that occur on dry pavements are associated with higher injury severity when compared to wet pavements, likely due to rider behavior adjustments in adverse weather conditions to compensate for the risk.
