NTUA conducted recently a research study aiming to capture Greek drivers acceptance and perceptions of the new Greek Road Traffic Code. This online questionnaire-based study exploited a sample of 400 participants inside and 400 participants outside Attica Region investigating general driving information, opinions and perceptions about the new Road Traffic Code. 42% of the participants consider the new fines for traffic violations to be fair and necessary, while 56%-63% of the participants inside/outside Attica consider the 30 km/h city-wide speed limit beneficial. 

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. In its first year, IMPROVA has made significant strides in understanding and assessing the LTC of road traffic crashes. These actions align with our core research questions and lay the foundation for innovative tools, methodologies and policy recommendations. 

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Seniors Safety Facts and Figures Report which refers to people aged 65 years and older. According to this report, seniors have the second highest mortality rate among all age groups, with an average of about 65 senior fatalities per million senior inhabitants in road traffic within the EU27. Moreover, when considering the mode of transportation, seniors experienced a considerably high number of fatalities in the most vulnerable modes. Specifically, in 2023 30% of senior fatalities were pedestrians, while 16% were cyclists.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Light Goods Vehicles (LGVs) Facts and Figures Report which refers to lorries under 3.5 tonnes. Throughout the observation period (2013-2023), the share of fatalities in crashes involving LGVs among all road fatalities ranged between 10% to 12% and about 3% of all road fatalities were LGV occupants. Looking at the EU, the number of fatalities in crashes involving LGVs decreased by 9%, comparing 2019 and 2023. The development of the number of fatalities in LGV crashes throughout the years varies across European countries, with Northern and Central European countries having a lower share of fatalities in LGV crashes in the total number of road fatalities than countries in Southern and Southeastern Europe.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Gender Facts and Figures Report which looks at fatalities on European roads distributed by gender. According to this Report, in 2023, the share of males among fatally injured road users was 77% male versus 23% of female fatalities within the EU countries.  The ratio of male to female fatalities has been stable between 2013 and 2023. Cyprus, Croatia, Greece, Malta, Portugal and Belgium have a share of male fatalities of 80% or higher. The absolute number of male fatalities has decreased by 15% in the period 2013-2023 and the number of female fatalities by 20% in the same time period.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory the Car Occupants Facts and Figures Report which refers to car drivers as well as car passengers (front or rear seat). According to this report, the total number of car occupant fatalities in the EU27 2023 were  9,007 and has decreased by 11% since 2019. Furthermore, 81% of fatally injured car drivers are men, with the highest rates in single vehicle crashes being recorded for the age group 20 to 24 years old. Remarkable is that two thirds of car occupant fatalities in the EU occurred on rural roads.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Buses & Heavy Goods Vehicles Facts and Figures Report which refers to fatalities in crashes involving buses/coaches and heavy goods vehicles (HGVs) on European roads. In 2023, 13% of all road fatalities in the EU27 occurred in crashes involving HGVs and 2% of road fatalities in the EU27 occurred in crashes involving buses/coaches.  The most fatalities in 2023 were recorded in Germany (456), France (387) and Poland (304) and the fewest in Luxembourg (3) and Slovenia (15) having continuous numbers throughout the time period. Moreover, it is remarkable that female share in fatalities in crashes involving buses/coaches (31%) is remarkably higher than the respective share in crashes involving HGVs and all crashes (23%).  

A NTUA Diploma Thesis titled “The impact of physical fitness on road safety and driver behaviour on rural roads” was recently presented by Marina Karachalia. An experimental procedure involving 46 participants aged 19–27 was conducted. The participants were evaluated in terms of their cardiorespiratory fitness through the Maximal Oxygen Uptake index (VO₂max) and their self-reported fitness habits and they were classified into two groups: high fitness and low fitness. The data was analyzed using linear and logistic regression models. Results suggest that high-fitness drivers have longer reaction times, greater variability in headway distance, higher average speeds, and, conversely, a lower probability of road accident involvement. Overall, higher physical fitness appears to be associated with more stable and controlled driving behavior, which, despite the increased reaction time, may contribute to reduced accident risk through improved decision-making.  

A NTUA Diploma Thesis titled “Investigation of Illegal Pedestrian Crossings in the Center of Athens” was recently presented by Marianthi Alverti. For this purpose a Stated Preference (SP) survey was structured in order to examine decision-making scenarios based on varying conditions of travel time, perceived crash risk, and personal comfort, with a dataset of of 212 responses. The analysis exploited binary logistic regression to examine the likelihood of illegal crossing, and generalized linear model to investigate the trade-offs pedestrians make between safety, time, and convenience given three different scenarios of camera use, traffic light with timer, and the baseline scenario to choose from. The models highlight the influence of time pressure, traffic conditions, and social components on individual decisions. The findings aim to showcase the importance of pedestrian decisions to prevent the likelihood of a road crash and, in this way, support more behavior-aware policy design, ultimately contributing to safer urban mobility systems.  

A NTUA Diploma Thesis titled “Investigation of Non-Compliant Pedestrian Crossings at Signalized Intersections Using Computer Vision Techniques” was recently presented by Natalia Mirogianni. To achieve this objective, an advanced video-based detection algorithm using data collected from a high-traffic intersection in Omonoia Square, in Athens was utilized. The dataset included detailed pedestrian and vehicle coordinates and speed characteristics, signal timing, and time-to-collision metric. The analysis consisted logistic regression, random forest classification, and point-biserial correlation to identify significant predictors of non-compliant behaviour and also to compare the effectiveness of the manual field and computer vision algorithm results. The findings contribute to the understanding of pedestrian violations and offer valuable insights for future implementation of automated monitoring systems and policy interventions for safer crosswalks.  

A NTUA Diploma Thesis titled “The impact of connected and autonomous vehicles on road safety with use of simulation”  was recently presented by Aikaterini Kalliakoudi. For this purpose an analysis based on simulation data derived from nine scenarios implemented in the city center of Athens was conducted. Additionally, traffic and geometric characteristics of the locations where the conflicts occurred were documented. The statistical analysis was carried out through the development of three models: two multiple linear regression models and one multinomial logistic regression model. The results indicated that the influencing factors for the above variables are related both to traffic composition (e.g., vehicle types) and infrastructure characteristics (e.g., speed limit, capacity). Furthermore, the increase in AV/CAV penetration in the network was found to have a positive impact on road safety, significantly reducing the number of vehicle conflicts.  

A NTUA Diploma Thesis titled “Factors Influencing Speed Limit Violations on Athens Road Network” was recently presented by Daphne Kyprouli. For this reason data collected by OSeven Telematics and OpenStreetMaps, which includes information such as road geometry indicators, safety measurements and driving behavior metrics were utilized. The analysis consisted statistical models and machine learning algorithms  aiming to predict speeding violations and understand the factors influencing them, with overall ten models created. The results demonstrated that speeding has a statistically significant correlation with various variables and improving driving behavior will consequently lead to a reduction of road crashes. The main factors affecting the likelihood of speeding in the examined road sections are the number of trips, the road section length and the percentage of mobile phone use, while slopes presented the least impact.  

A NTUA Diploma Thesis titled “Critical factors of self reported behaviour and safety of electric scooter users in Europe” was recently presented by Ibabi Hasim. For this reason statistical models were utilized in order to analyze the factors that lead electric scooter users to engage in dangerous driving behaviors, based on data from the third edition of the international ESRA survey (E-Survey on Road Users’ Attitudes). Findings highlight the importance of factors such as the acceptance of risky behaviors, the existence of legislation, the level of urbanization, and age. Furthermore, mandatory helmet use and stricter rules prove to be particularly effective in reducing violations. Finally, some proposals are provided that could improve the road safety of electric scooter users, such as strengthening the legal framework, stricter enforcement, and infrastructure improvement.  

The Horizon Europe research project CulturalRoad has recently released the CulturalRoad 2^nd Newsletter, which provides information on the latest outcomes of the EU-funded CulturalRoad Project aiming to develop innovative methodologies to ensure the equitable deployment of Cooperative, Connected, and Automated Mobility (CCAM) services. This version of the Newsletter announced the release of the Project’s first animated video, a perfect way to learn more about the Project, by presenting its vision for more equitable, inclusive and connected mobility. It also emphasizes on the five key pillars of mobility equity and the Five-Pointed Rating Star System, designed to evaluate the level of equity of CCAM systems within their specific environments. 

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Rural Areas Facts and Figures Report which refers to public roads outside urban boundary signs, excluding motorways. In 2023, 53% of all road fatalities in the EU27 occurred on rural roads. In the last decade between 2013 and 2023, the number of fatalities on rural roads decreased by 16%, compared to a 15% decrease on other roads (urban roads and motorways). Remarkable is that car occupants make up more than half (56%) of all fatalities on rural roads. The share of fatalities on rural roads is proportionally higher during the daytime at the weekend and lower at nighttime on working weeks.

A paper titled Safety contributing factors analysis of older vulnerable road users: General and local perspectives authored by Xueyu Zhang, Xueson Wang, Mohamed Abdel-Aty, George Yannis and Guangzhu Luo has been published in Accident Analysis & Prevention. This paper utilizes an analytic approach to explore the effects of contributing factors for older vulnerable road users’ (VRUs) crashes, with particular attention to the integration of general and local analysis. Socio-economic, road network, public facility, traffic enforcement and older VRU crashes were collected in the grids and gradient tree-boosted Tweedie compound Poisson models as well as geographically weighted random forests were employed. The findings suggest that population and healthcare played an important role in predicting older VRU crashes. The concentration areas for older people, including healthcare facilities, markets, and bus stops, demonstrate that improvement countermeasures should adapt to local conditions. 

NTUA has recently released the 2025 version of Key Road Safety Performance Indicators in Greece in the framework of the EU project Trendline. These KPIs are derived from nationwide field observations in 2025 on four key Road Safety Performance Indicators (KPIs): speed, seatbelt use, helmet use, and driver distraction. Key findings show that only 71% of vehicles on rural roads complied with speed limits (less than in 2022), seatbelt use among rear passengers remained as low as 57%, helmet use increased for both front (85%) and rear riders (60%) and mobile phone use increased on rural roads (12%). These results provide valuable evidence for targeted road safety interventions and the future alignment of Greece with national and EU safety targets.

A paper titled Trajectory-based indicators to determine the local character of intersection conflicts: A micro-spatial analysis authored by Andreas Hula, Apostolos Ziakopoulos, Angel Losada, Andrea Schaub, Peter Saleh and George Yannis has been published in Accident Analysis & Prevention. This paper utilizes the Mobility Observation Box (MOB), which provides a flexible data collection to be used in subsequent video analysis. To facilitate potential MOB uses, this study leverages over 51 h of naturalistic video data at a busy Vienna intersection to advance road safety research, by employing random parameters binary modelling of the likelihood of critical conflict occurrence and Gaussian generalized additive spatial modelling to identify key factors influencing the absolute values of conflict angles on critical conflicts only. The findings suggest that all road user types were ultimately less likely to be involved in safety–critical conflicts compared to cars in both leading and following roles, with the exception of cyclists in the leading role. Within the micro-spatial analysis, the kinematic parameters of the second road user only (speed, max acceleration and max deceleration), the duration of the interaction as well as intersection-specific local effects related to the position of the leading road user were all found to influence the transformed absolute value of the angles of critical conflicts. 

A new book titled The Routledge Handbook of Sustainable Urban Transport edited by Lucy Budd, Stephen Ison and Maria Attard has been recently published. This Handbook offers a comprehensive exploration of urban transport sectors, as well as the challenges, impacts and issues being faced.

•  Traveller and driver safety in an urban context

The United Nations Department of Economic and Social Affairs announced the first ever UN Decade of Sustainable Transport 2026 – 2035 starting in 2026. The Implementation Plan of the UN Decade of Sustainable Transport is expected to serve as a strategic framework to coordinate actions, mobilize resources, and monitor progress towards sustainable transport worldwide. It will be an opportunity to further raise awareness of transport’s crucial role in advancing the Sustainable Development Goals and to gather and rally new solutions, resources and partnerships to advance sustainable transport globally. Ensuring safety in sustainable transport is essential to protect lives, reduce crashes and build trust, resilience and reliable in transport systems. 

The World Bank Global Road Safety Facility (GRSF) together with SSATP has published the 2025 Status Report on Road Safety in Africa analyzing findings for road safety on the African continent. The 2025 Africa Status Report on Road Safety reveals that, despite having only 3% of the global vehicle fleet, Africa accounts for 24% of global road fatalities with 259,601 deaths annually. This highlights the urgent need for safer pedestrian and cycling facilities to protect vulnerable road users.  

The ETSC Annual Report 2024, highlights a year of impactful advocacy and cross-border collaboration in the pursuit of safer roads across Europe. From championing 30 km/h urban speed limits and tackling loopholes in EU vehicle safety regulations, to supporting EU Member States through the EU-funded Road Safety Exchange programme, ETSC continues to be a leading voice for road safety in Europe. The Report also celebrates milestones such as Finland’s PIN Award for outstanding progress on road safety, the #IWillBeALifesaver campaign, and award-winning educational initiative LEARN!   

The UN Road Safety Fund continues to support low and middle-income countries to do that by providing road safety expertise to close gaps on road safety data, enforcement practices, vehicle safety, legislative frameworks, post-crash care, urban street design, among other topics. This UNRSF 2024 Annual Report highlights how collective efforts are saving lives and driving systemic change in road safety.

The Bloomberg Philanthropies Initiative for Global Road Safety (BIGRS) works with Governments and communities to prevent road crashes, deaths and injuries. Since 2007, the initiative has helped implement proven road safety interventions across 22 countries. Currently, the initiative is supporting work in 27 cities and two states across 15 low- and middle-income countries. Its Resources Hub includes case studies and guidance focusing on five areas: strengthening legislation and leadership, enhancing data collection and surveillance, changing road user behavior with media campaigns and enhanced enforcement, improving road infrastructure and advancing vehicle safety. 

The Horizon Europe research project metaCCAZE has recently released a new Blog Post authored by George Yannis on the new Greek Road Traffic Code. The new Road Traffic Code introduces city-wide 30 km/h speed limit in all urban streets of one or two directions with a single lane per direction, making Greece the second EU country after Spain to implement such a measure. It is also rationalising and simplifying penalties and linking them to the offences’ seriousness and magnitude. Furthermore it introduces a number of correct and necessary traffic management provisions with emphasis on motorcycles and the 30km/h speed limit in cities. 

The Horizon 2020 research project PHOEBE has recently released the PHOEBE 5th 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. Particular attention was given to the conclusion of the Project’s model development for the safety of vulnerable road users and the safety use case implementation. 

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Urban Areas Facts and Figures Report which refers to public roads inside urban boundary signs. According to this Report, in 2023,  38% of all road fatalities in the EU27 occurred on urban roads. In the last decade between 2013 and 2023, the number of fatalities on urban roads decreased by 16%, which is similar to the 15% decrease on other roads (rural roads and motorways). Furthermore, vulnerable road users (pedestrians, cyclists, mopeds, motorcycles) make up 68% of fatalities on urban roads, while pedestrians are involved in 34% of all fatalities.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Regional Distribution Facts and Figures Report which looks at the regional distribution of road fatalities on European roads. According to this Report, the number of fatalities per million inhabitants  is highest in Eastern Europe. Some of the regions with the highest mortality rates in 2023 can be found in Greece, Romania and Bulgaria. Most countries have both low and high mortality regions. A large variety can be found in decreases and increases of fatalities between regions. Furthermore, the trend in the rate over time tends to vary between regions. In Lithuania, Poland and Slovenia there has been a decrease in all regions. Furthermore, Bulgaria and Belgium have the regions with the highest rates in car occupant fatalities per million inhabitants, while this is also the case for cyclists in Belgium and the Netherlands. The mortality rate of powered two-wheelers is high throughout the South and East of Europe  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Motorways Facts and Figures Report which refers to  motorways, which are public roads with dual carriageways, and at least two lanes each way. In 2023, 9% of all road fatalities in the EU27 occurred on motorways. Furthermore, the proportion of 25–64-year-old fatalities on motorways was higher, while the proportion of 65+ year olds killed was lower compared to other road fatalities (rural and urban roads). Moreover, 67% of motorway fatalities were between 25 and 64 year old, compared to 52% on other roads (rural and urban roads).  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Junctions Facts and Figures Report which refers to road fatalities at junctions, which are locations where two or more roads meet and traffic can change between different routes, directions, or sometimes modes of travel. According to this report, in 2023 19% of all road fatalities in the EU27 occurred at junctions and road fatalities at junctions in the EU have decreased by 6% since 2019. Moreover, 55% of junction fatalities in the EU27 occur on urban roads. Remarkable is that vulnerable road users are being involved in more than half of all fatalities at junctions (62%), while this share is only 44% for all non-junction fatalities.  

A paper titled Investigating the impact of in-vehicle warning information complexity on drivers: The role of working memory capacity and cognitive load authored by Kunchen Li, Wei Yuan, George Yannis, Fuwei Wu and Chang Wang has been published in Accident Analysis & Prevention. This Paper investigates the impact of the complexity of the warning messages on the behavior and physiological states of the driver, taking into account individual differences in working memory capacity and cognitive load levels. A total of 37 participants were recruited to conduct a mixed design driving simulation experiment, with working memory capacity treated as a between-subjects factor. The analysis included correlation as well as a Generalized Linear Mixed-effects Model (GLMM). The findings suggest that visually rich warnings lead to increased braking reaction times, especially between drivers having low working memory capacity and under high cognitive load. These findings offer theoretical insights to assist manufacturers in designing human-centered, personalized, and adaptive in-vehicle warning systems.

A paper titled Mild cognitive impairment, Alzheimer’s disease dementia, and predictors of driving cessation: A 7-year longitudinal prospective study authored by Petros Stamatelos, Ion Beratis, Panagiota Hatzaki, Alexandra Economou, Nikolaos Andronas, Dimosthenis Pavlou, Stella Fragkiadaki, Dionysia Kontaxopoulou, Anastasios Bonakis, Leonidas Stefanis, George Yannis and Sokratis Papageorgiou has been published in Journal of Alzheimer’s Disease. This paper aims to identify predictors of driving cessation among patients with mild cognitive impairment (MCI) or mild Alzheimer’s disease dementia (AD). The 109 participants underwent a neurological, neuropsychological and driving simulator assessment with re-evaluations after 48 and 84 months including a structured interview with the patients and their caregiver. Primary endpoints were driving cessation, death and progression to dementia. The findings suggest that age, SVF and mTWT are significant predictors of driving cessation among MCI and AD patients. Furthermore, driving simulator may be a promising component of driving evaluation. 

A paper titled Exploring the impact of driver feedback on safety: A systematic review of studies in real-world driving conditions authored by Armira Kontaxi, Apostolos Ziakopoulos and George Yannis has been published in Transportation Research Part F: Traffic Psychology and Behaviour. This study systematically investigates the role of driver feedback towards improving driving behavior, by utilizing the PRISMA framework and by reviewing 34 studies. The studies are analyzed in terms of their experimental frameworks, including sample sizes, feedback delivery methods, and feedback phases, along with statistical models employed to assess the impact of feedback on driving behavior and road safety. The findings suggest that driver feedback can significantly reduce crash risks and improve driving behavior, but further research is required to explore its long-term effects and broader applicability.

The Foundation VINCI Autoroutes has recently published the results of the 15^th Euro-Barometer for Responsible Driving by Ipsos, in which representative attitudes of Europeans at the wheel are recorded, enabling also the monitoring of the evolution of risky driving and good practices to better target prevention messages in European countries. According to this study, Greece has the highest rate of drivers (82%) that use their mobile phone during driving in Europe (EU average 77%). Furthermore, most of the Greek drivers (81%) admits exceeding the speed limit by a few km/h. In addition, 40% of drivers in Greece admitted continuing driving even when they feel tired, whereas the respective EU average is 32%. 

A paper titled Eco-driving in rural areas: a sustainable approach to reducing emissions and enhancing road safety authored by  Marios Sekadakis, Penny Kourenti, Thodoris Garefalakis, Apostolos Ziakopoulos and George Yannis has been published in Case Studies on Transport Policy. This study aims to examine the advantages of eco-driving in rural and mountainous rural settings by employing an experimental methodology and utilizing data collected from 39 participants across a range of driving simulation scenarios and their characteristics through a questionnaire survey. To achieve this goal linear and logistic regression models were implemented. The analysis revealed that eco-driving significantly reduces pollutant emissions reduces fuel consumption by 7%, and reduces the probability of crashes by 66.2%. Furthermore, the quantitative analysis confirmed that mountainous rural networks, due to their topographical complexity, are associated with higher emissions, increased fuel consumption, and elevated crash risk compared to flatter rural environments, highlighting the need for terrain-specific eco-driving strategies. These findings highlight the promise of eco-driving practices in improving environmental sustainability and safety, particularly in rural environments. 

A paper titled Systematic review and meta-analysis of take-over time from automated driving at SAE levels 2 and 3 to manual control authored by Marios Sekadakis and George Yannis has been published in Transportation Research Part F: Traffic Psychology and Behaviour.  This study systematically investigates how Take-Over Time (TOT) is affected by road environments, traffic volumes , SAE levels, Human-Machine Interface (HMI) designs and Take-Over Requests (TORs) alerts, utilizing the the PRISMA framework, by reviewing 51 studies. Meta-regression and sensitivity analyses were conducted to quantify the effects of key factors on TOT. Findings suggest significant correlations between shorter TOT and higher maximum longitudinal and lateral accelerations, greater lane variability, and a moderate increase in crash rates, highlighting potential safety concerns. This study highlights the critical role of adaptive systems tailored to specific driving contexts, road conditions, and automation levels. 

A paper titled Quantifying the impact of COVID-19 on driving behavior and mobility patterns: A four-country comparative overview authored by Eva Michelaraki, Marios Sekadakis, Christos Katrakazas, Apostolos Ziakopoulos and George Yannis has been published in Case Studies on Transport Policy  The objective of this study was to quantify the impact of COVID- 19 on driving behavior, mobility patterns and road safety through the exploitation of data from sensors via a smartphone application developed by OSeven Telematics. To achieve this goal a random dataset from its database for four countries (i.e. Greece, Saudi Arabia, Cyprus and Brazil) was collected and analyzed, utilizing a logistic regression model. The results revealed that speeding percentage, average driving speed, as well as harsh events (except for Cyprus) were increased during the lockdown period. Moreover, a significant decrease in traffic volumes and numbers of people walking in each country was demonstrated during the pandemic. These findings highlighted the need for enhanced traffic law enforcement, smart traffic management solutions and sustainable mobility planning to mitigate the heightened road safety risks observed during lockdown periods. 

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 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 and KFV has published at the European Road Safety Observatory, the Children Safety 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 exploited 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. 

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 featuring 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 European Road Safety Charter of the European Commission, has recently published a new Article focusing on helmet use and seatbelt/child restraint systems, aiming to increase the attention to theis use. Studies suggest 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. 

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.

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.

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. 

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. 

The European Union has recently adopted the new Directive to strengthen cross-border enforcement of road traffic rules. The newly adopted rules tackle several road safety issues by enhancing collaboration among Member States, streamlining offender identification and facilitating fine enforcement. Cooperation between national Authorities will not only focus on the most common and serious offenses like speeding, drunk and drugged driving, but also on several other hazardous behaviours. 

The International Road Traffic and Accident Database (IRTAD) of the International Transport Forum (ITF/OECD) published the Road Safety Annual Report 2024, on the development of road safety in 2023. It is based on data from 40 IRTAD member countries, with some preliminary data also for the year 2024. The main findings revealed that  in 2023, there were 2.338 less fatalities than in 2022, also road deaths decreased by 2% in the first half of 2024 compared to 2023. However, the considerable journey ahead should be acknowledged, in order to achieve the global target of halving road deaths and serious injuries by 2030.

A paper titled Driving Automation Systems Penetration and Traffic Safety: Implications for Infrastructure Design and Policy authored by Antonia Antonakaki, Maria Oikonomou, Thodoris Garefalakis and George Yannis has been published in Infrastructures. The study aims to evaluate the impact of Autonomous Vehicle (AV) penetration rates on traffic safety, through the use of microscopic simulation scenarios, utilizing multiple linear and multinomial logistic regression models. The findings highlight that higher AV penetration rates generally improve traffic safety, although the coexistence of conventional vehicles and vehicles equipped with driving automation systems introduces traffic heterogeneity, potentially influencing safety outcomes. These results suggest that while AVs have a positive effect on road safety, further analysis is needed to address the complexities introduced by mixed-traffic conditions.
