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.

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.
