It provides indicators for the risk of traffic death for different road user groups, thereby enhancing the evaluation, monitoring and benchmarking of road safety outcomes.
An NTUA Diploma Thesis titled “Critical factors for the identification of traffic safety events in urban areas” was recently presented by Foteini Bardi. According to the results, the random forest model proved to produce more reliable results predicting traffic safety events with a lower false alarm rate, when compared to binomial logistic regression. Moreover, factor analysis demonstrated that data representing one minute before the event can be described by speed, the deviation of the vehicle from the middle of the road and the distance from the right boundary line. Similarly, data during the event can be better described through speed and longitudinal and lateral acceleration.
Critical factors of the influence of mobile phone use on driving behavior, based on smartphones’ data, October 2020
An NTUA Diploma Thesis titled “Critical factors of the influence of mobile phone use on driving behavior, based on smartphones’ data” was recently presented by Sofia Akritidou. The aim of this Diploma Thesis is to examine and model the critical factors of mobile phone use on driver behavior through the exploitation of data from smartphone sensors. The results revealed that the parameters affecting the use of mobile phone while driving are four, the percentage of driving duration with speed above the speed limit, distance driving, average deceleration, and average speed. For the general, urban and rural models, the average deceleration had the most significant impact, whereas for the highway model, distance was the most significant parameter.
An NTUA Diploma Thesis titled “Critical driving parameters affecting speeding using data from smartphones” was recently presented by Dimosthenis-Marios Tzoutzoulis. The aim of this Diploma Thesis is to identify the critical driving parameters affecting speeding using data from smartphones. The results demonstrate that the number of harsh accelerations, the percentage of mobile use and the distance of the trip affect the speeding percentage and are correlated with the aggressive behavior of the drivers. Furthermore, increased average acceleration does not always lead to breaking speed limits. Finally, male drivers tend to drive faster in comparison with women.

The results demonstrate that annual card cost and travel time savings are the main factors for the acceptance of the annual card. Furthermore, men, young people and high-income travelers are more likely to accept the annual card and environmental traffic policies. Finally, it was observed that the environmental awareness of drivers affects the acceptance of environmental traffic policies.
Apostolos Ziakopoulos defended his PhD Thesis on Spatial Analysis of Road Safety and Traffic Behaviour using High Resolution Multi-parametric Data, July 2020
Apostolos Ziakopoulos has successfully defended his PhD dissertation titled: Spatial Analysis of Road Safety and Traffic Behaviour using High Resolution Multi-parametric Data. This PhD thesis was carried out at the Department of Transportation Planning and Engineering at the School of Civil Engineering of the National Technical University of Athens under the supervision of Prof. George Yannis, using data from OSeven Telematics.
The main objective of this PhD Dissertation is the spatial analysis of harsh event frequencies in road segments using multi-parametric data, including (i) high resolution naturalistic driving and driver behavior data from smartphone sensors, (ii) microscopic road segment geometry and road network characteristic data from digital maps and (iii) high resolution traffic data. Spatial analyses were performed on two parallel pillars: (i) Prediction models were developed in an urban road network training area, with the intent to transfer them to a second urban road network testing area and assess their predictive performance and (ii) Causal models including road user behavior and traffic input data were calibrated in an urban arterial study area per traffic state, in order to investigate additional underlying correlations in an effort to further understand the phenomena of harsh braking and harsh acceleration frequencies. Geographically Weighted Poisson Regression (GWPR) models, Bayesian Conditional Autoregressive Prior (CAR) models and Extreme Gradient Boosting algorithms with random cross-validation (RCV XGBoost) and spatial cross-validation (SPCV XGBoost) were implemented.
An NTUA Diploma Thesis titled “Preferences towards e-scooters in Athens” was recently presented by Vasilis Maragkoudakis. The objective of this Diploma Thesis is to investigate the preferences towards e-scooters in Athens and to identify the most important factors affecting traveler modal choices in Athens. Logistic regression models were developed (multinomial and binary), which demonstrated that the probability of choosing an e-scooter depends largely on the cost, time, comfort, attitudes, habits and the demographic characteristics of the respondents. The faster and the more economical is the trip and the more familiar is the traveler with e-scooters is, the more likely he/she is to choose them over other means of transport.
An NTUA Diploma Thesis titled “Event identification based on driving characteristics on rural roads” was recently presented by Akrivi Varela. The aim of this Diploma Thesis is to identify events based on driving characteristics on rural roads and determine the main factors that can describe the situation before and during an event. Results showed that random forest model performs much better than the binomial logistic regression in identifying event occurrence with very few false alarms. Moreover, speed and longitudinal acceleration along with total distance driven from the beginning of the driving session, turned out to better describe the case of driving one minute prior to an event. Finally, driving during an event can be sufficiently described through speed, the deviation of the vehicle from the middle of the road as well as the time headway with the vehicle ahead.

The aim of this Diploma Thesis was the development of a model that, by filling in the values for several parameters, could estimate the socio-economic impact of the automated traffic for different penetration scenarios, compare these scenarios results and demonstrate each parameters’ impact on the total cost. The model application results highlighted the crucial benefits of automated traffic and quantified the socio-economic parameters impact depending on the penetration scenarios and the reference year, with most important the role of cost of travel time.
A Diploma Thesis titled “Analysis of pedestrians distracted behaviour talking on mobile phone” was recently presented by Dimitra Typa. The aim of this Diploma Thesis was to investigate the impact of hand-held cell phone conversation on pedestrians’ traffic and safety behaviour, when crossing signalized intersections. An outdoor-environment experiment, through video recording, was conducted in real road conditions, in three signalized intersections at the centre of Athens for the purpose of comparing the behaviour of distracted and non-distracted pedestrians. The results of the models’ application demonstrated that distraction caused by hand-held cell phone conversation had a negative impact on pedestrians’ main traffic and safety characteristics, since, in general, mobile use not only decreases pedestrians’ speed but also increases their probability of being involved in an accident with an oncoming vehicle.
A paper titled “Driving Safety Efficiency Benchmarking Using Smartphone Data” authored by Dimitrios Tselentis, Eleni Vlahogianni, and George Yannis is now published in Transportation Research Part C: Emerging Technologies. This paper aims to provide a methodological framework for the comparative evaluation of driving safety efficiency based on Data Envelopment Analysis (DEA). The analysis considers each driver as a Decision-Making Unit (DMU) and aims to provide a relative safety efficiency measure to compare different drivers based on their driving performance. The proposed methodological framework is tested on data from fifty-six (56) drivers during a 7-months period. Findings help distinguish the most efficient drivers from those that are less efficient. Most common inefficient driving practices are identified (aggressive, risky driving, etc.) and driving behaviour is comparatively evaluated and analyzed.
A paper titled “A review of spatial approaches in road safety” authored by Apostolos Ziakopoulos, and George Yannis is now published in Accident Analysis and Prevention. The aim of the present research is to critically review the existing literature on different spatial approaches through which researchers handle the dimension of space in its various aspects in their studies and analyses. Specifically, the use of different areal unit levels in spatial road safety studies is investigated, different modelling approaches are discussed, and the corresponding study design characteristics are summarized in respective tables including traffic, road environment and area parameters and spatial aggregation approaches.
The European Transport Safety Council (ETSC) has published a Report titled “Briefing: EU Strategic Action Plan on Road Safety”. In June 2019, the European Commission adopted the EU Road Safety Policy Framework 2021-2030, outlining specific policy measures planned for 2021-2030 and developing on the EU Strategic Action Plan on Road Safety published in May 2018. ETSC stresses the need for stronger measures including legislation and a wider coverage of existing and emerging road safety issues that will be essential to addressing the recent stagnation in progress on reducing road deaths in the EU.
Twelve EU Member States are joining forces to share smart ideas for improving road safety, as part of a new EU-funded project: “Road Safety Exchange”, coordinated by the European Transport Safety Council (ETSC) and launched in Brussels on October 9th, 2019. The three-year EU Road Safety Exchange project aims to tackle the current important disparities between the various EU countries and will link up experts on one hand from Bulgaria, Greece, Lithuania, Poland, Portugal, Romania, and on the other hand from Austria, France, Ireland, the Netherlands, Spain and Sweden. Transport experts from the twelve participating countries will work together to share best practice on reducing speed, building safe infrastructure and improve enforcement, data collection, as well as the safety of pedestrians and cyclists in urban areas.
The International Road Traffic and Accident Database (IRTAD) of the International Transport Forum (ITF/OECD) published the full version of the Road Safety Annual Report 2019, which provides an overview of road safety performance for 41 countries. The report outlines the most recent road safety developments and provides comparative data for the main road safety indicators. It also offers detailed analysis by road user, age group and types of road. It describes the crash data collection process in IRTAD countries, the road safety strategies and targets in place and information on recent trends in speeding, drink-driving and other aspects of road user behaviour.
A paper titled “A systematic cost-benefit analysis of 29 road safety measures” authored by Stijn Daniels, Heike Martensen, Annelies Schoeters, Wouter Van den Berghe, Eleonora Papadimitriou, Apostolos Ziakopoulos, Susanne Kaiser, Eva Aigner-Breuss, Aggelos Soteropoulos, Wim Wijnen, Wendy Weijermars, Laurent Carnis, Rune Elvik, Oscar Martin Perez is now published in Accident Analysis and Prevention. For the purposes of this study the authors collected and (re-)analyzed evidence in order to conduct cost-benefit analyses (CBAs) for 29 road safety measures. The information on crash costs was based on data from a survey in European countries. A systematic procedure was applied including corrections for inflation and Purchasing Power Parity in order to express all the monetary information in the same units (EUR, 2015). Cost-benefit analyses were carried out for measures with favourable estimated effects on road safety and for which relevant information on costs could be found. Results were assessed in terms of benefit-to-cost ratios and net present value and are included also at the SafetyCube DSS.
NACTO’s Guidelines for Regulating Shared Micromobility outline best practices for cities and public entities regulating and managing shared micromobility services on their streets. Its recommendations were developed to reflect the wide variety of experiences that North American cities have had in regulating and managing shared micromobility. Shared micromobility is still in its infancy and there are outstanding questions and option for which there is not yet a defined best practice, as highlighted within these Guidelines.
Road traffic crashes are not just statistics, they affect real lives and real people. Many people have been affected by road traffic crashes, or know people whose lives and relationships have been torn apart by these needless tragedies. The Global Alliance of NGOs for Road Safety launched a survey aiming to bring forth the voices of people to highlight the problem and call for governments to act urgently. The results will be released at the Third Global Ministerial Conference on Road Safety and disseminated through press releases, publications, mass and social media. They will provide evidence to show government leaders what needs to be done at local, regional, and global levels to save lives.
Within the European Mobility Week 2019, the European Commission and the Global Alliance of NGOs for Road Safety co-organised a Road Safety Roundtable in Brussels on 16 September. During this event, a commitment from European cities, coordinated by POLIS and Eurocities, entitled “The New Paradigm for Safe City Streets” was handed over including 10 principles to be recognized by the cities, as necessary for sound and effective action for traffic safety.
The UN General Assembly published recently a Report on Improving Global Road Safety, prepared by the World Health Organization in consultation with the United Nations regional commissions and other partners of the United Nations Road Safety Collaboration. The Report highlights that while the number of road traffic deaths has stabilized, as indicated in the Global Status Report on Road Safety 2018, significant reductions have not been observed, and road traffic injuries are now the leading cause of death for children and young adults between the ages of 5 and 29 years.
Driving difficulties as reported by older drivers with mild cognitive impairment and without neurological impairment, 2019
A paper titled “Driving difficulties as reported by older drivers with mild cognitive impairment and without neurological impairment” authored by Sophia Vardaki, Anne E. Dickerson, Ion Beratis, George Yannis and Sokratis G. Papageorgiou is now published in Traffic Injury Prevention. The purpose of this study was to explore the factors determining driving difficulties as seen from the viewpoint of 30 older drivers with mild cognitive impairment (MCI) and 30 age-matched controls without cognitive impairment. The analysis revealed that 2 factors underlie MCI perceptions of driving difficulties, representing (1) difficulties associated with late detection combined with slowed response to relevant targets in the peripheral field of view and (2) difficulties associated with divided attention between tasks requiring switching from automatic to conscious processing particularly of long duration.
The European Transport Safety Council (ETSC) has published a Report titled “Road Safety Priorities for the EU 2020-2030: Briefing for the new European Parliament”. In June 2019, the Commission published a new Strategic Action Plan on Road Safety that includes a new long-term target to halve road deaths by 2030 as well as, for the first time, a target to reduce serious injuries by the same amount. The EU must implement this new policy framework so that it ensures both the highest practicable level of safety and a fair distribution of safety across the European Union. New legislative proposals on improving both infrastructure and vehicle safety are currently being finalised. Their further implementation and the development of new legislation in other areas will be in the hands of newly elected MEPs over the period 2019-2024.
The European Transport Safety Council (ETSC) has published a Report titled “Independence in Investigation of Transport Accidents”. The aim of this Report is to promote a set of principles for independence of transport accident investigation in Europe, under which the requirements for independent investigation could be met by the EU itself, by each Member State and by any other European country.
The EU-funded EuroMed Transport Support Project (EuroMed) and World Health Organisation (WHO) released a joint Report titled: “Understanding and bridging the differences between country-reported and WHO-estimated road traffic fatality data“. It focuses on the considerable challenges in collecting complete, accurate and reliable road traffic fatality data that some countries worldwide are facing. Moreover, it attempts to explain the disparity between WHO estimates and country-reported data on road traffic fatality and provide suggestions on what steps countries can take to strengthen their data systems.
A Diploma Thesis titled “Investigation of traffic and safety behaviour of pedestrians texting or web-surfing” was recently presented by Marilia Ropaka. The regression analyses developed in this research pointed out that in high pedestrian traffic, mobile use not only decreases pedestrians’ speed, regardless of their age, but also increases their probability of being involved in an accident with an oncoming vehicle. Results indicated that distraction caused by texting or web-surfing had a negative impact on pedestrians’ main traffic and safety characteristics.
Impact of economic, social and transport indicators on serious road injuries in the European Union, 2019
A Diploma Thesis titled “Impact of economic, social and transport indicators on serious road injuries in the European Union” was recently presented by Maria Charalampidi. Generalized Linear Models application lead to the conclusion that the percentage of passenger cars with EuroNcap scores 5 stars has the most important impact and its increase leads to serious road injuries decrease. Moreover, the increase of the percentage of buses leads to significant decrease not only to the number of serious road injuries but also to the severity of road accidents.
Analysis of driver behaviour through smartphone data: The case of mobile phone use while driving, 2019
A paper titled “Analysis of driver behaviour through smartphone data: The case of mobile phone use while driving” authored by Eleonora Papadimitriou, Anastasia Argyropoulou, Dimitris Tselentis, and George Yannis is now published in Safety Science. The aim of this paper is to explore driving behaviour during mobile phone use on the basis of detailed driving analytics collected by smartphone sensors from OSeven Telematics. The data came from a sample of one hundred drivers (18,850 trips) during a naturalistic driving experiment over four months. The results suggest that mobile phone use while driving may be accurately predicted by the model in more than 70% of cases.
Road Safety is acknowledged as a priority issue in the EuroMed partner countries (Algeria, Egypt, Jordan, Lebanon, Morocco, Tunisia). However, the collection of credible road safety data is a major challenge. In this context, the recent EuroMed Report, which was launched with the active contribution of NTUA, consists of provision of technical assistance on setting up road safety reliable, harmonized and comparable data collection systems at the EuroMed Partner Countries and sharing at regional level. The Final Report concludes that the adoption of common definitions for road crash variables and values strongly depends on the successful implementation of basic definitions (accident, road, casualty severity) and the systematic and complete reporting of crashes and casualties.
On 28 May, 45 experts from Europe and Australia were gathered in Gothenburg, Sweden, within the framework of the Horizon 2020 project Levitate, in order to discuss which societal impacts Connected and Automated Vehicles will have. Levitate is building tools to help European cities, regions and national governments prepare for a future with increasing levels of Automated Vehicles in passenger cars, urban transport services and urban logistics. The Workshop marked the first meeting of the LEVITATE Stakeholder Group, which aims to facilitate a continuous dialogue between experts, users and the consortium about the impacts of Connected and Automated Transport (CAT).
NTUA contributed actively to the 1st Stakeholder Workshop with the following presentation: CATS-PST Connected and Automated Transport Systems Policy Support Tool
The European Commission – DG Move has published a study titled “Sustainable Transport Infrastructure Charging and Internalisation of Transport Externalities” which aims to assess the extent to which existing policies internalise the external and infrastructure costs of transport and to discuss ways by which further internalisation could be achieved. As input for this assessment, the infrastructure and external costs of the various transport modes are estimated and a comprehensive overview of transport taxes and charges applied in the various countries is provided. According to the study results, the most important cost category is accident costs equating to 29% of the total external costs, which on the contrary of most other costs it is not targeted by any taxes or charges aiming its reduction.
The European Commission – DG Move has published a Staff Working Document titled “EU Road Safety Policy Framework 2021-2030 – Next steps towards “Vision Zero” which includes details as to how it intends to put its Strategic Action Plan on Road Safety into practice . This Document includes a first list of Road Safety Key Performance Indicators (KPI), elaborated in close cooperation with Member States and the active contribution of NTUA, that will be monitored across the EU to underpin the target of 50% reduction in fatalities and serious injuries by 2030. The list (including indicators like vehicle safety, seat belt and helmet wearing rate, speed compliance and post-crash care) is a living document that will be developed further over time, but first data can be gathered on this basis from next year.
The European Transport Safety Council (ETSC) published the 13th edition of PIN Annual Report , with the active contribution of NTUA, presented at the 2019 Annual PIN Conference which took place with great success on 19 June, 2019 in Brussels. According to this PIN Report, the new European figures show that the number of persons killed last year fell by just 1% and the EU target to cut road deaths in half over the decade to 2020 looks well out of reach.
Ireland was the winner of this year’s ETSC Road Safety Performance Index (PIN) award, being the second safest EU Member State in 2018, in terms of road mortality (road deaths per million inhabitants) and having moved up five places in the ranking of EU countries since 2010 when it held the 7th place.
The 1st newsletter of the Horizon 2020 project Levitate was recently released highlighting the key activities of the first 6 months of the project. It contains an inspiring interview with Rune Elvik, Senior research officer at TØI, suggesting that any progress in Connected and Automated Transport cannot eliminate the human factor. Furthermore, it highlights the results from the first Workshop of the Levitate Stakeholder Group in Gothenburg on May 2019 and of the respective presentation of Levitate project at the scientific Workshop organized by the National Technical University of Athens (NTUA) on ‘Digitalisation and Road Safety Research’ in Athens on May 2019.
A new book titled ‘La sécurité routière en France – Road Safety in France‘ authored by Laurent Carnis, Catherine Gabaude and Marie-Line Gallenne, was published in May 2019. Since the 1970s, road accidents have undergone a remarkable evolution, which has led to fewer fatalities and fewer casualties on French roads. But the accidents remain too numerous and still defeat the chronicles. Greater road safety justifies measures that give rise to lively discussions where everyone claims to be an expert. This book guides the reader through themes such as trauma victims, alcohol or drugs driving.
A paper titled “Safety Culture among Private and Professional Drivers in Norway and Greece: Examining the Influence of National Road Safety Culture” authored by Tor-Olav Nævestad, Alexandra Laiou, Ross O. Phillips, Torkel Bjørnskau and George Yannis is now published in Safety Journal. This study investigates road safety culture (RSC) as an explanation for this discrepancy by: (1) Comparing the road safety behaviours among professional and private drivers in Norway and Greece, (2) Examining factors influencing road safety behaviours, focusing especially on national road safety culture, and (3) Examining the influence of road safety behaviours and other factors (e.g., demographic and work-related variables) on accident involvement. The results indicate that aggressive violations are more similar among private and professional drivers within the national samples, than across the national samples, while seat belt use seems to vary according to the professional versus private dimension.
A paper titled “Safety assessment of control design parameters through vehicle dynamics model” authored by Stergios Mavromatis, Alexandra Laiou, and George Yannis is now published in Accident Analysis and Prevention. An existing vehicle dynamics model was utilized to define design parameters up to which steady state cornering conditions apply and consequently lift the restrictions of the point mass model. Aiming to assess critical safety concerns in terms of vehicle skidding, the motion of a passenger car was examined over a range of design speed values paired with control design elements from AASHTO 2011 Design Guidelines as well as certain values of poor pavement friction coefficients.

The European Road Transport Research Advisory Council (ERTRAC) has published the “Safe Road Transport Roadmap – Towards Vision Zero: Roads without Victims”, with the active contribution of NTUA. The main objective of this ERTRAC roadmap is to provide a joint stakeholder view on the road safety research needs in Europe. The roadmap is based on the current state of the art and the identified challenges to reach the ambitious goals set for the EU. In this roadmap, ERTRAC proposes a set of eleven high priority road safety research and innovation needs, which should be implemented by providing ample room for citizens and road users themselves to engage.
The European Transport Safety Council (ETSC) has published a Report titled “Road Safety Priorities for the EU 2020-2030: Briefing for the European Parliamentary Elections”. This ETSC Report suggests additional legislation priorities over the period 2019-2024, concerning: a) the improvement of cyclists, pedestrians and powered two wheelers safety, b) automated and connected mobility, c) the reduction of serious injuries on EU roads, d) the efficient enforcement, e) the drug driving and f) the education and training (revision of the European Driving License Directive).
The European Commission’s Directorate General for Mobility and Transport (DG Move) published a Report titled: “Transport in the European Union: Current Trends and Issues“. The Report sets out the key trends and issues for the single European transport area, the development of a safe transport infrastructure network across EU countries, and the external costs of transport, accompanied with the respective country analyses. Special emphasis is given to the consequences of road accidents.
The International Transport Forum (ITF/OECD) published recently a new Report: “Road Safety in European Cities – Performance Indicators and Governance Solutions”. This reports benchmarks road safety performance for 72 urban areas, mostly in Europe, and illustrates governance solutions to improve urban road safety with case studies conducted in Lisbon (Portugal) and Riga (Latvia). The report proposes new road safety indicators to assess the level of risk for each mode of transport. It finds that a modal shift away from private motor vehicles could significantly enhance road safety in dense urban areas and deliver public health benefits associated with increased physical activity and improved air quality.
According to the European Commission preliminary statistics, fewer people died on European roads in 2018 but more efforts are needed to make a big leap forward. In 2018, there were around 25.100 fatalities in road accidents in the EU 28. This is a decrease of 21% compared to 2010, and 1% compared to 2017. The EU countries with the best road safety results in 2018 were the United Kingdom (28 deaths/million inhabitants), Denmark (30/million), Ireland (31/million), and Sweden (32/million), whereas the best improvement since 2010 was demonstrated by Greece (-45%) and Lithuania (-43%). With an average of 49 road deaths per one million inhabitants, this confirms that European roads are by far the safest in the world, but it also shows that we are off track to reach our target of halving the number of road deaths by 2020.
A paper titled “The European road safety decision support system on risks and measures” authored by the Horizons 2020 SafetyCube project team is now published in Accident Analysis and Prevention. The European Road Safety Decision Support System is an innovative system providing the available evidence on a broad range of road risks and possible countermeasures. This paper describes the scientific basis of the DSS. The structure underlying the DSS consists of (1) a taxonomy identifying risk factors and measures and linking them to each other, (2) a repository of studies, and (3) synopses summarizing the effects estimated in the literature for each risk factor and measure, and (4) an economic efficiency evaluation instrument (E3-calculator).

Combined impact of road and traffic characteristics on driver behavior using data from smartphones, 2019
A Diploma Thesis titled “Combined impact of road and traffic characteristics on driver behavior using data from smartphones” was recently presented by Virginia Petraki. High resolution driving behavior data were collected using sensors of smartphones which were combined with traffic and road geometry characteristics and subsequently were depicted spatially using GIS. From the application of these models it is observed that in road segments there is an increase in the number of harsh events if average traffic volume per lane increases in the respective segments. Furthermore, in junctions as the average occupancy increases, there is an increase in harsh accelerations, and as average speed increases more harsh decelerations occur.
A Diploma Thesis titled “Correlation of driver behaviour and fuel consumption using data from smartphones” was recently presented by Eva Michelaraki. The aim of this Diploma Thesis is the correlation of driver behaviour and fuel consumption using data from smartphones. To achieve this objective, data collected from 17 drivers who participated at a naturalistic driving experiment for four months are analyzed. The results demonstrated that there was a remarkable reduction in fuel consumption, by improving the way participants were driving and also a smoother and a greener driver behavior was achieved. A stronger correlation has emerged between harsh accelerations and fuel consumption, but also speed, braking, smartphone usage while driving, driving at night and demographic features had a direct impact on fuel consumption.
