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.

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. 

A paper titled “Analysis of harsh braking and harsh acceleration occurrence via explainable imbalanced machine learning using high-resolution smartphone telematics and traffic data” authored by Apostolos Ziakopoulos has been published in Accident Analysis & Prevention. Subsequently, Synthetic Minority Oversampling TEchnique (SMOTE) was applied due to class imbalance and then binary classification was conducted to detect factors leading to harsh brakes (HB) and harsh accelerations (HA) occurrence.  Results reveal strong nonlinear effects on harsh event occurrence, with individual speed and traffic flow parameters showing the highest influence, followed by exposure parameters such as segment length and pass count. However, network characteristics such as number of lanes, and speed limit had limited influence on harsh events occurrence, as did behaviors such as mobile phone engagement and speeding.

The Royal Society for the Prevention of Accidents (RoSPA) has recently published a Synthesis Report titled “Speed Limits” which focuses on the interventions regarding effective speed management. More precisely, new principles about setting speed limits are emerging, based on an assessment of the combined risk relating to the infrastructure, travel speeds, volume and mix of traffic by type (including vulnerable road users). Furthermore, signs are the primary way of communicating the speed limit of a road to drivers, with principles of effective speed limits signing been uniformity, consistency, simplicity, relevance and legibility. 

The Royal Society for the Prevention of Accidents (RoSPA) has recently published a Synthesis Report titled “Speed” which focuses on the relationship between speed and risk. Precisely, as average traffic speed reduces, so does the likelihood of a crash resulting in injury that is recorded by the police. Furthermore, effective speed management policies are likely to include an integrated package of measures, including credible speed limits, enforcement, education and engineering. RoSPA is a leading voice in health and safety that has campaigns to reduce avoidable crashes on the road. 

Using the International Road Assessment Programme (iRAP) methodology, road safety infrastructure changes and safer speeds within more than 1,000 infrastructure projects have prevented almost 700,000 deaths and serious injuries in 74 countries since 2016, according to a new paper with Johns Hopkins University published in PLOS One. This study is the first to measure the impact of road projects financed by governments, development banks and private-sector road operators around the world using the iRAP methodology and tools. 

BBC World News published an article about a revolutionary idea that changed the way Europe regarded road collisions. Claes Tingvall, as the head of Road Safety for the Swedish Road Adminstration in 1995, tried to balance road safety with other factors, including cost, driver preferences and the impact on the economy of changing traffic flows. Tingvall found that crash victims were not, as many in the road transport sector, assumed – drunk and irresponsible drivers but for the most part, they were people who made small mistakes. He introduced the Vision Zero fatalities as ultimum target and the Safe System approach as the way to share the responsibility also to the Authorities and all those involved in the design and the operation of the road and traffic system to be preventive and forgiving to human errors, eliminating the crash and injury risk. 

The Forum of European Road Safety Research Institutes (FERSI) published a paper titled “Secondary roads – Road Safety challenges“, which demonstrates the important contribution of secondary rural roads to the burden of road traffic injuries and fatalities. Furthermore, it identifies the most important road safety challenges and emphasizes the corresponding need for addressing these by introducing appropriate remedial road infrastructure measures and new technologies, supported by consistent research and innovation.   

NTUA conducted a research titled “The Impact of Ridesharing Services in Athens” to investigate ridesharing socio-economic impact in Athens. The research concludes that the introduction of ridesharing in Athens has a significant positive impact to social welfare of the city improving environment quality, traffic conditions, road safety and economic growth, mainly due to the travel demand swift from private cars to ridesharing services. The emergence of ridesharing service in Greek islands is also discussed.

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Protective Equipment Safety Performance Indicator (SPI) Report which focuses on the prevalence and the road safety effects of road users’ use or non-use of bicycle helmets, motorcycle helmets, seat belts and Child Restraint Systems (CRS). Moreover, where feasible, these reports look at whether SPIs are related to existing policies and regulations, providing possible effective interventions to increase safe behaviour, or discourage unsafe behaviour.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Main Factors causing Fatal Crashes Thematic Report, in which the role of key risk factors is quantified and discussed, based on the most recent international literature. These factors concern speeding, driving under the influence of alcohol, distraction and other psychoactive substances, and non-use of protective equipment. Addressing in priority the above causes of fatalities in Europe, through safe-by-design thinking, i.e. prevention, control and mitigation of the consequences of these errors, can contribute significantly towards the ambitious EU targets of halving fatalities by 2030 and eliminating them by 2050.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Subjective Safety Safety Performance Indicator (SPI) Report which  focuses on the subjective experience of feeling safe or unsafe in road traffic using different transport modes. Based on data from the ESRA project it is shown that road users feel safer in order importance as: pedestrians (6.7-8.8), car drivers (5.9-8.3), cyclists (4.5-7.3) and motorcyclists (4.5-6.5).  

Dimitris Nikolaou has successfully defended his PhD dissertation titled: Machine learning-based road crash risk assessment fusing infrastructure, traffic and driver behaviour data, under the supervision of NTUA Prof. George Yannis. Two distinct databases were developed; the former concerned motorway segments and the latter concerned urban and interurban road segments. Several statistical models (e.g. Logistic and Negative Binomial Regression, Hierarchical Clustering, Spatial Error Model) and Machine Learning Algorithms (e.g. Decision Tree, Random Forest, K-Nearest Neighbour and Support Vector Machine) were implemented. The results revealed that crash frequency on motorway segments is positively correlated with the traffic volume, the segment length, the number of harsh accelerations and the number of harsh brakings per segment trips. It was also concluded that geometrical and behavioural parameters can be combined to meaningfully conduct road safety analysis spatially and proactively, as they are highly correlated with harsh braking Surrogate Safety Measures.  

The European Commission published the road fatalities collision matrix in urban roads in the EU. The available EU-wide data for 2022 contained in the CARE database, demonstrate that 38% of road traffic fatalities occured in urban areas, with vulnerable road users (pedestrians, cyclists and users of powered two-wheelers) representing almost 70% of total fatalities. This collision matrix shows clearly that urban road user fatalities occur overwhelmingly when a crash involves cars and vulnerable road users, underlining the need to improve protection of these vulnerable road users. Furthermore, the high number (31% of the total crashes) of single vehicle crashes of cars and two-wheelers demosntrate the critical role of speeding in the cities.   

The European Commission published a breakdown of fatalities in the EU by road user and (other) “main vehicle” involved in the crash. The matrix shows clearly that fatalities overwhelmingly occur in collisions involving cars, and the need  to increase the protection of vulnerable road users such as pedestrians, motorcyclists and cyclists. EU policies are already evolving in this direction with the new mandatory safety measures introduced by the General Safety Regulation focused on VRUs.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Road Safety Country Profiles, which provide a comprehensive overview of the road safety status in the 27 EU Member States and three EFTA countries for the period 2012 to 2021. These country profiles exploit data and information from a range of sources, including the CARE and other international databases, as well as national sources, in order to highlight current road safety outcomes, performance indicators, policy & measures and structure & culture for each country. 

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Cyclists Thematic Report which refers to users of a conventional bicycle or a pedelec/e-bike, i.e., an electric powered bicycle offering pedal assistance up to approximately 25 km/h. This Thematic Report describes how cyclists participate in traffic, as well as cyclists in relation to road safety hazards. Furthermore, countermeasures about infrastructure, bicycle-related measures, protective measures, enforcement and traffic education are suggested.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Seniors Safety Thematic Report which refers to people aged 65 years and over. This Thematic Report describes how seniors participate in traffic, as well as seniors in relation to road safety hazards.  Moreover, countermeasures about infrastructure, road users fitness-to-drive and training, vehicles systems, automation and bicycles for seniors are suggested.  

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Fatigue Safety Performance Indicator (SPI) Report which focuses on the percentage of drivers driving non-fatigued. This report aims to give insight into the differences between groups of countries regarding their road user behaviour or attitude. According to this report, the mean percentage of self-reported fatigued driving (during the previous 30 days) in Europe is 23%.
