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.

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.

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.

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. 

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 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. 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. 

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.

A paper titled “Cost benefit analyst of reducing speed limits in Athens to 30 Km/h” authored by Stella Roussou, Virginia Petraki, Katerina Deliali, Armira Kontaxi and George Yannis has been published in Case Studies on Transport Policy. The study highlights the benefits of lowering speed limits in Athens from 50 km/h to 30 km/h, including a 30-40% reduction in traffic crashes and a 20-25% decrease in injury severity . Additionally, the policy could lead to lower by 10-15% CO2 emissions and improve conditions for pedestrians and cyclists. The overall benefits are projected to outweigh the costs by 3 to 5 times, making it a highly effective policy for safer, more sustainable urban mobility. 

The Horizon Europe research project metaCCAZE has recently released the metaCCAZE 1st 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. The potential of zero emission shared mobility solutions in real and diverse urban environments were tested in four Trailblazer Cities (i.e. Amsterdam, Munich, Limassol, Tampere). 

The Young and aging drivers Thematic Report of the European Survey of Road Users’ Safety Attitudes (ESRA) has been published, as prepared by TIRF, with the support of NTUA, containing a wealth of information on road safety in 39 countries across Europe, America and Asia-Oceania, based on the ESRA3 survey. This Thematic ESRA3 Report describes  the self-declared behaviours and perceived acceptability (social and personal) related to driving while impaired, speeding, and distraction, among young and aging drivers. Key findings show that aging drivers (65-74) are less likely than younger drivers to engage in risky behaviours like impaired driving, speeding, or distracted driving, such as using a hand-held phone or reading messages.  

The Speeding Thematic Report of the E-Survey of Road Users’ Safety Attitudes (ESRA) has been published with the active contribution of BASt and NTUA, containing a wealth of information on road safety in 39 countries across Europe, America and Asia-Oceania, based on the ESRA3 survey. This Thematic ESRA3 Report describes the self-declared behaviour, acceptability, attitudes and support for policy measures regarding speeding. Key results on self-reported speeding behaviors show that car drivers least frequently admitted to driving too fast for road/traffic conditions (27.8%-31.0%), followed by exceeding speed limits in built-up areas (37.1%-47.3%), with males, younger drivers (in Europe), and certain regional variations (e.g., America8) displaying higher frequencies of speeding across road types.  

The Infrastructure Thematic Report of the E-Survey of Road Users’ Safety Attitudes (ESRA) has been published with the active contribution of NTUA, containing a wealth of information on road safety in 39 countries across Europe, America and Asia-Oceania, based on the ESRA3 survey. This Thematic ESRA3 Report describes the use and the safety perception of infrastructure among different road users, including car drivers, moped riders and motorcyclists, cyclists and pedestrians. The results revealed that car drivers in Europe have the highest usage of inter-city motorways, while America leads in using thoroughfares and high-speed roads within cities. Moreover, strong linear relationships were discovered between the perceived safety of road infrastructure and road fatality rates.  

The European Commission with the active contribution of  NTUA,  SWOV and KFV has launched a Vulnerable Road Users promotion activity focusing on children, cyclists, pedestrians and Powered Two-Wheelers (mopeds and motorcycles). According to the new Reports from the European Road Safety Observatory, the high vulnerability of non-motorised road users in urban areas is highlighted, with a disproportionately high number of fatalities in these areas for children (46% of total fatalities) and pedestrians (73%), compared to the average for all road users (38%). Recommendations to reduce fatalities among vulnerable users, including infrastructure improvements, protective equipment and vehicle design are also provided.     

Eva Michelaraki has successfully defended her PhD dissertation titled: Improving driver safety tolerance zone through holistic analysis of road, vehicle and behavioural risk factors, under the supervision of NTUA Prof. George Yannis. Data from 190 drivers who participated in a large on-road and simulator driving experiment were exploited. An innovative methodology, consisting of both statistical analyses (Generalized Linear Models, Structural Equation Models) and machine learning techniques (Decision Trees, k-Nearest Neighbors, Neural Networks and Random Forests) was implemented. Results indicated that RF models outperformed the DT and kNN models across all metrics, making them the most effective for predicting speeding and headway, with overall accuracy up to 90%. It was also revealed that task complexity was positively correlated with risk, while coping capacity was negatively correlated with risk, indicating that drivers with higher coping capacity are better equipped to handle challenging driving situations.  

The European Commission is making available within the European Road Safety Observatory, the Road Safety Atlas application, exploiting data from the CARE database, the EU database with disaggregate data. It is an application openly available with several detailed thematic maps on road fatalities and extended backround data available, including statistics per country and comparisons between countries. It provides a user-friendly interface to discover up to date road safety indicators for European countries.   

In a recently published study conducted at Stanford University (USA), using a range of parameters for each scientist’s research contribution and influence, million scientists data from Scopus database were analysed. According to this study 1,019 Greek scientists are contained in the global top 2%, among which 159 researchers from the National Technical University of Athens (NTUA). 25 Professors from the School of Civil Engineering of NTUA are among the top 2% researchers in the world (4 within the top-ten of NTUA), while 7 of them from the Department of Transportation Planning and Engineering, (5 within the top-ten of the School of Civil Engineering). 

A paper titled “Detection of dangerous driving behaviour with wide-scale data from smart systems and machine learning techniques” authored by Hector Kamvoussioras, Thodoris Garefalakis, Eva Michelaraki, Christos Katrakazas and George Yannis has been published in Advances in Transportation Studies. Specifically, four classification models: Ridge Classifier (RC), Support Vector Machines (SVM), Random Forests (RF), and eXtreme Gradient Boosting (XGBoost) – were developed. These models were utilized to categorize driving behaviour into three defined levels of “Safety Tolerance Zone (STZ)”. The results revealed that the RF and XGBoost models achieved high accuracy, reaching 95% in prediction accuracy. By identifying the factors that influence risky driving behaviour, this framework offers valuable insights for guiding safety interventions , ultimately contributing to enhanced road safety. 

A paper titled “Modeling and Sustainability Implications of Harsh Driving Events: A Predictive Machine Learning Approach” authored by Antonis Kostopoulos, Thodoris Garefalakis, Eva Michelaraki, Christos Katrakazas and George Yannis has been published in Sustainability. This study addresses the complex task of predicting dangerous driving behaviors through a comprehensive analysis of over 356,000 trips, enhancing existing knowledge in the field and promoting sustainability and road safety. Findings indicate that Gradient Boosting and Multilayer Perceptron excel, achieving recall rates of approximately 67% to 68% for both harsh acceleration and braking events. The application of machine learning algorithms, feature selection, and k-means clustering offers a promising approach for improving road safety and reducing socio-economic costs through sustainable practices.
