The IRF Data Warehouse is a web-based global road data platform and warehouse that can complement and support national and regional efforts to collect and manage data. The IRF Data Warehouse also contributes to capacity-building and advocacy activities on a number of topics and in particular, road safety. The entire time series of the IRF World Road Statistics enables immediate and effective data analysis and is complemented by a series of dashboards and interactive data visualisation tools. 

The International Transport Forum (ITF/OECD) published recently a new Report: “Monitoring Progress in Urban Road Safety Report”,  tracking progress in reducing the number of road traffic fatalities and serious injuries in cities since 2010. It presents traffic safety data collected in 48 cities participating in the ITF Safer City Streets network and compares urban with national road safety trends. 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.  

The International Road Traffic and Accident Database (IRTAD) of the International Transport Forum (ITF/OECD) published the Road Safety Annual Report 2020, which provides an overview of road safety performance for 42 IRTAD countries. Based on the latest data, the report describes recent road safety developments in these countries and compares their performance against the main road safety indicators. This year, a highly interesting special section on the impact of covid-19 pandemic on road accidents is added.  NTUA has contributed to the detailed report for Greece.  

The European Commission has recently published the “Study on the feasibility, costs and benefits of retrofitting advanced driver assistance to improve road safety“, prepared by VTT and Ecorys. This study examined the technical feasibility of various retrofit ADAS systems (voluntarily or mandatory installable) while demonstrated the potential safety impacts of retrofitting the vehicle fleet and presented a cost-benefit assessment for the measures.  Detection and warning of pedestrians and cyclists nearby the front or side of the vehicle proved having the highest benefit-cost ratio, as addressing the Vulnerable Road Users safety, being the key current road safety problem. 

The  World Health Organisation (WHO) published recently the “European Regional Status Report on Road Safety 2019”  with the active contribution of NTUA. The European Regional Status Report on Road Safety describes the progress made by Governments in the Region. This Report demonstrates that over 221 people are killed on roads every day in the WHO European Region while thousands more are injured or disabled, with long-lasting effects.  People from the eastern part of our Region bear the highest burden of road-traffic mortality and morbidity. 

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.  

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 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.  

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 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. 

Basic characteristics of road fatalities in Greece for the period 1991-2017 are summarised in a comprehensive Table prepared by the NTUA Road Safety Observatory (data source: ELSTAT). Since 2007, there are approximately 900 less road fatalities per year in Greece. According to these time series data a spectacular decrease in road fatalities for children 0-14 years old (-71%), young drivers (-61%) and on motorways (-61%) is observed during the last decade. On the contrary, fatalities decrease during the last decade is quite limited for moped riders (-26%), older drivers (-28%) and at rural (36%) and urban (37%) junctions. 

Since 54 years, the  International Road Federation (IRF) World Road Statistics (WRS) continue to be the major comprehensive, universal source of statistical data on road networks, traffic and inland transport. This year the WRS 2018 (data 2011-2016) features more than 205 countries, with data on over 45 road related topics, with the active contribution of NTUA for the Greek data. What is highlighted this year is that freight transport is almost evenly split between road and rail in both Europe/ Central Asia region and North America. Passenger transport in these regions is essentially by road with 88% of passengers travelling by roads in Europe/Central Asia and 99% in North America. These statistics allow governments and urban planners to pinpoint where in the transport sector to focus their time and resources to ensure passenger safety and maximum economic benefits.  

The World Health Organisation (WHO) published an Interactive Map on Global Road Safety, based on the recently published Global Status Report on Road Safety 2018. This Interactive Map is a highly useful tool allowing to visualize a wealth of information and several road safety parameters per country as well as to highlight the shocking fact that every 23 seconds a road user looses their life. 

The Global Status Report on Road safety 2018 has been published by World Health Organisation (WHO) with the active contribution of NTUA, in December 2018, highlighting insufficient progress as the number of annual road traffic deaths has reached 1.35 million. Road traffic injuries are now the leading killer of people aged 5-29 years. The report suggests that the price paid for mobility is too high, especially because proven measures exist. These include strategies to address speed and drinking and driving, among other behaviours; safer infrastructure like dedicated lanes for cyclists and motorcyclists; improved vehicle standards such as those that mandate electronic stability control; and enhanced post-crash care. Drastic action is needed to put these measures in place to meet any future global target that might be set and save lives.

A paper titled “Identification of patterns of driver speeding behaviour and safety margins from tangent to curve” authored by Eleonora Papadimitriou, Stergios Mavromatis, Dimosthenis Pavlou and George Yannis is now published in Advances in Transportation Studies. This paper presents a novel definition of drivers’ safety margins reflected in speed profiles on a tangent to curved road design. These safety margins are based on a vehicle dynamics model, which is implemented to assess the speed variation at impending skid conditions from tangent to curve on the basis of several parameters. Data from a driving simulator experiment are used to test the proposed methodology, explore driver’s speed profiles and the parameters affecting drivers’ safety margins. The results suggest that drivers’ safety margins towards the examined curve are considerable, with the majority of the drivers using less than 55% of the available vehicle engine power. 

The European Commission’s Directorate-General for Research and Innovation published a Report titled “Analysis of the state of the art, barriers, needs and opportunities for setting up a Transport Research Cloud”, with the active contribution of NTUA Professor George Yannis. This Report focuses on the requirements for data sharing within the transport research community. In particular, the Report examines the potential of a Transport Research Cloud (TRC) as a subset of the European Union’s European Open Science Cloud (EOSC) initiative. Six domain experts collected data based on their personal experiences, contacts, prior research and a survey sent out to other researchers in the transport domain to enable a preliminary analysis concerning the needs, barriers and potential benefits for the domain should a TRC be realized. Road Safety constitutes a major component of this Transport Research Cloud.  

The European Commission’s Directorate General for Mobility and Transport (DG Move) published the Final Report of the “Study on powered two-wheeler and bicycle accidents in the EU, SaferWheels”, with the active contribution of NTUA. The SaferWheels study was conducted to investigate accident causation for traffic accidents involving powered two-wheelers and bicycles in the European Union. The objective of the study was to gather PTW and bicycle accident data from in-depth crash investigations, obtain accident causation and medical data for those crashes, and to store the information according to an appropriate and efficient protocol enabling a causation-oriented analysis. 

The Horizons 2020 research project InDev (In-depth Understanding of Accident Causation for Vulnerable Road Users) recently published a handbook with focus on vulnerable road users entitled: How to analyse accident causation? This handbook was developed to help road safety professionals diagnose road safety problems by gaining more insights into the mistakes by road users that lead to collision. It describes various road safety methods that can be applied for studying the safety of vulnerable (and other) road users, including: accident data analysis, conflict and behavioural observations, self-reporting and naturalistic studies and road safety audit and inspection.  

The Eurostat Regional Yearbook 2018 provides a detailed picture relating to a broad range of statistical topics across the Regions of the EU Member States, as well as the Regions of the EFTA and candidate countries, including the European Regions with the lowest and highest road accident rates. Each chapter presents statistical information in maps, tables, figures and infographics, accompanied by a descriptive analysis highlighting the main findings.  

European Commission – DG for Research and Innovation in their Success Stories Web-page recently published the SaferAfrica H2020 project, which has been taken place with the active contribution of NTUA. As a continent, Africa has some of the most lethal roads in the world. A lack of road safety protocols, wanting road conditions and poor post-crash emergency response systems make for alarmingly high fatality rates. To help turn this around, the EU-funded project SaferAfrica is driving policies aimed at improving road safety. “Europe can play an important role by supporting African countries in improving road safety and achieving the Action Plan targets [African Road Safety Action Plan 2011-2020],” says project coordinator Luca Persia. “In this view, the project aims at building favourable conditions and opportunities for the effective implementation of road safety actions in African countries by setting up a Dialogue Platform between Africa and Europe.” 

In the framework of the European Survey of Road users’ safety Attitudes (ESRA), NTUA released 3 new infographics, regarding “Drivers’ self-declared behaviour” , “Drivers’ attitudes towards unsafe behaviour”  and “Drivers personal and social acceptability” .

ESRA is a joint international initiative of 26 research centers and road safety institutes; the project has surveyed road users in 38 countries on 5 continents. The purpose of this network is to collect comparable data on the opinions, attitudes, and behaviour of road users concerning road safety and mobility, and to provide scientific evidence for policy making at the national and international levels. The Updated Main Report (2017 edition) of ESRA has been published containing the results from the survey in 38 countries, including 13 Latin America countries.

A Diploma Thesis titled “Investigation of Drivers’ Preferences Towards New Innovative Vehicle Insurance Schemes” was presented by Emmanouil Konstantinopoulos in July 2018, with the support and data from OSeven Telematics. The objective of this Diploma Thesis is to investigate the most important factors that determine the demand of Greek drivers for vehicle insurance services comprising new innovative insurance schemes of Pay As You Drive and Pay How You Drive (PAYD & PHYD), taking into account critical characteristics of driving behaviour. The analysis demonstrated that the young and the female drivers show higher probability of selecting PAYD/PHYD schemes, while the Freelancers are more reluctant to such schemes.  

Serious crashes on inter-urban roads may be slashed by a quarter over the next 30-40 years with the introduction of automated vehicles. However, the journey may be far from easy, with a mixed fleet transition and vital need for roads that cars can read, according to recent Report released by EuroRAP. The Report, the third in the “Roads that Cars Can Read” series, examines the relationship between road infrastructure and safety for conventional and increasingly-autonomous vehicles (AVs) and provides a framework for infrastructure safety investment.   Other Reports in the series: “Roads that cars can read I: A consultation paper” – 2011 and “Roads that cars can read II: A quality standard for road markings and traffic signs on major rural roads” – 2013.

The Updated Main Report (2017 edition) of the European Survey of Road users’ safety Attitudes (ESRA) has been published containing the results from the survey in 38 countries, including 13 Latin America countries, with the active contribution of NTUA. The updated version of the ESRA webpage with Deliverables and Publications includes the 2017 Main Report in 3 languages (English, Spanish, French), six Thematic Reports on European drivers attitudes, and the country fact sheets. 

The European Union Road Federation (ERF) and the Federation of European Motorcyclists’ Associations (FEMA) have published a joint position paper, called ‘Improving infrastructure safety for powered two-wheelers’. Only in 2017 power two-wheelers fatalities (motorcycles and mopeds) counted for 17% of the total road victims, while accounting only for 1,8% of the total traffic flow. Both ERF and FEMA strongly believe that road safety for motorcyclists can be significantly improved by looking at the design of road infrastructure. 

The European Transport Safety Council (ETSC) has published the 35th PIN Flash Report “An Overview of Road Death Data Collection in the EU“, with the active contribution of NTUA. The goal of this PIN Flash Report is to gather information on road death data collection in different PIN countries and to find out if and how countries cross-check or complement road death data recorded by the police with alternative sources. This Report provides very useful information to exchange good practice on how to improve road death data collection and recording. 

Since 53 years, the  International Road Federation (IRF) World Road Statistics (WRS) continue to be the major comprehensive, universal source of statistical data on road networks, traffic and inland transport. Over the past years, the WRS have proved to be an invaluable and internationally accepted reference tool for governments, NGOs, investments banks, research institutes and anyone analyzing and reporting trends in key subject areas like traffic volumes and vehicle usage, road expenditure, road safety, energy consumption and emissions. This year, the WRS 2017 (data 2010-2015) features more than 205 countries, with data on over 45 road related topics, presented in nine substantive sections, with the active contribution of NTUA for the Greek data.  

European Commission (DG Employment, Social Affairs and Inclusion) released a very interesting guide containing good practices for managing work related vehicle risks in the EU, with a specific focus on workplace transport, driving for work and working on or near a road. With this interactive e-guide many good practices are provided as well as an overview of relevant regulations and information in three key aspects of vehicle risks: safe driving for work, workplace transport safety, and working on or near a road. 

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 2018, which provides a detailed insight of road safety performance for 28 countries. The Annual Report outlines the most recent road safety developments across IRTAD countries and provides comparative data for the main road safety indicators also detailed by road user, age group and type of road. Furthermore, the IRTAD Annual Report contains syntheses of the the road safety strategies and targets in place as well on recent trends in speeding, drink-driving and other aspects of road user behaviour.  

A paper titled “How many crashes are caused by driver interaction with passengers? A meta-analysis approach” authored by Athanasios Theofilatos, Apostolos Ziakopoulos, Eleonora Papadimitriou, and George Yannis is now published in Journal of Safety Research. Conversation and other interactions with passengers while driving induce a level of distraction to the person driving. This paper conducts a qualitative literature review on the effect of passenger interaction on road safety and then extends it by using meta-analysis techniques.  The findings of the random-effects meta-analyses that were carried out showed that driver interaction with passengers causes a non-negligible proportion of road crashes, namely 3,5% of crashes regardless of the age of the passengers and 3.8% when child and teen passengers are excluded. 

The Hellenic Statistical Authority (ELSTAT) has issued a comprehensive set of statistics on Casualty Road Accidents in Greece for 2016, comprising time-series for the decade 2007-2016. In 2016, 11.318 road accidents with fatalities or serious injuries occurred in Greece, recording a decrease of 1.1% in comparison with 2015 and ending an impressive road fatalities drop during the economic crisis of almost 50%. During the last five years, road fatalities in Greece have decreased by 29% (since 2011), however injury road accidents decreased only by 17%. The rate fatalities per number of vehicles has decreased by 30% since 2011.  

The International Road Traffic and Accident Group (IRTAD) of the International Transport Forum (ITF/OECD) published recently a new Report: “Cooperative Mobility Systems and Automated Driving”. Automated vehicles could make roads safer as well as reduce congestion. Whether society will be able to capture these benefits while minimizing negative impacts depends on effective regulation of self-driving vehicles. The technology is still largely experimental and mass use is likely to take decades. This report reviews the range of existing service concepts for automated driving systems and technologies, the operational environments they require and assesses the need for regulatory action.  

“The Road to Zero Report” was developed by the Road to Zero Coalition, together with the RAND Corporation, setting a goal to eliminate traffic fatalities in the U.S. by 2050. The report is the first of its kind in the U.S. and identifies proven, life-saving actions for the short, mid, and long-terms that should be taken by federal, state, and local government officials; automakers; technology manufacturers; business leaders; insurance agencies; law enforcement; and safety advocates.  

The European Commission’s Directorate General for Mobility and Transport (DG Move) published the EU good practice guide: Safer roads for all. It includes Road Safety Statistics in EU, and good practices in EU countries with different safety performance levels. The EU success story is the result of many contributing factors: making road safety a political priority; broad cooperation across borders for a true European road safety area; adoption of the ‘safe system’ approach and the ‘vision zero’ perspective; target setting, data collection and continuous monitoring of results; and dedicated actions ranging from education and awareness campaigns to legislative action and safety focused technical vehicle regulations. 

A paper titled “Structural equation model analysis for the evaluation of overall driving performance: A driving simulator study focusing on driver distraction” authored by Panagiotis Papantoniou is now published in Traffic Injury Prevention, Volume 19, 2018 – Issue 3, pp. 317-325. 95 participants from all age groups were asked to drive under different types of distraction (conversation with passenger, cell phone use) in urban and rural road environments with low and high traffic volume in a driving simulator experiment. Then, a structural equation model is developed in which overall driving performance is estimated as a latent variable based on several individual driving simulator measures. The implementation of the structural equation model allows for the assessment of driving behaviour in terms of overall performance and not through individual performance measures, which allows an important scientific step forward from piecemeal analyses to a sound combined analysis of the interrelationship between several risk factors and overall driving performance.. 

The Overseas Development Institute (ODI) launched a publication titled “Securing safe roads: the politics of change” which is an output of the project: The politics of road safety. Over the past 10 years, road safety has been escalated to an issue of international concern. Together with the World Resources Institute Ross Center for Sustainable Cities, ODI undertook research in three middle-income cities: Nairobi, Kenya; Mumbai, India; and Bogotá, Colombia. In this report, ODI synthesizes the findings from these case studies concluding with a series of strategies to improve road safety.  

POLIS, the European cities and regions network for innovative transport solutions released a discussion paper entitled: “Road Vehicle Automation and Cities and Regions”. Polis promotes the discussion about vehicle automation, focusing on the car as opposed to lorries and buses and on ‘personal mobility’ rather than logistics. The aims of this paper are among others: a) to raise awareness of AV developments and their potential mobility and safety impact among city and regional administrations and to assist them in setting transport policies and plans to deal with them and b) to raise awareness of city and regional transport policies among vehicle manufacturers and other automated vehicle players.  

The European Transport Safety Council (ETSC) has published a Position Paper titled “EU Funds for Road Safety in the Multiannual Financial Framework 2021-2027“. In this paper, ETSC presents recommendations for funding for road safety initiatives within the next long-term EU budget, known as the Multiannual Financial Framework (MFF). These recommendations should support work towards meeting the EU’s current target to reduce road deaths by 50% by 2020 and the new targets for 2030 as well as the long-term Vision Zero.  

The European Transport Safety Council (ETSC) has published the 34th PIN Flash Report “New EU vehicle safety standards essential to reducing child road deaths“, with the active contribution of NTUA. More than 8,000 children aged 0-14 years have been killed in road traffic collisions over the last ten years in the European Union, new data show. Half of the children killed were travelling in cars, a third were walking and 13% were cycling. ETSC says that measures that can reduce speeding are critical to preventing the deaths of more children and is calling for the EU to require vehicle safety technologies such as Intelligent Speed Assistance (ISA) and Automated Emergency Braking (AEB) that can detect pedestrians and cyclists to be fitted as standard on all new cars. 

The UNECE Global Road Safety Model SafeFITS developed by NTUA is now freely available online. The primary objective of the state of the art “Safe Future Inland Transport Systems (SafeFITS)” model is to assist Governments and Decision Makers to identify the most appropriate road safety policies and measures, allowing them to simulate the impact and effectiveness of different possible interventions based on real-world data.  

SafeFITS Final Report e-publication: 

Jean Todt, United Nations Secretary-General’s Special Envoy for Road Safety stated that: SafeFITS provides a tool to help Member States review their current road safety situation and priorities, assisting them to determine the most appropriate and beneficial policy options for their national context, under the framework of the Decade of Action for Road Safety.

The European Transport Safety Council (ETSC) has just published a Report titled ‘Call for mandatory alcohol interlocks in vans, lorries and buses across the EU‘. ETSC is looking at how to reduce the 5.000 deaths still caused by drink-driving in the European Union each year and comes up with two main recommendations: the EU should require alcohol interlocks: a) to be fitted in all new professional vehicles and b) retrofitted to cars used by repeat drink-driving offenders. 

Antonio Avenoso, Executive Director of ETSC said that: the alcohol interlock programmes have proven to be one of the most effective measures for tackling repeat drink-driving offences and should be extended across the European Union.

The Directorate General for Mobility and Transport (DG Move) of the European Commission released the Statistical Pocketbook 2017 ‘EU Transport in figures‘. In this Statistical Pocketbook, key road safety Tables are contained, together with several other Tables on transport statistics, providing a complete picture of current trends in transport in Europe. Data on road fatalities for the EU member states and associate countries allow for time series comparisons and country rankings. 

The International Road Traffic and Accident Database (IRTAD) of the International Transport Forum (ITF/OECD) published the full version of the Annual Report 2017, which provides an overview of road safety performance for 2015 in 40 countries, with preliminary data for 2016, and detailed reports for each country. It includes tables with cross country comparisons on key safety indicators and puts special emphasis on road safety for an ageing population, which represents a growing concern in many countries. The positive trend over the last few years of reduced road fatalities did not continue in 2015 and 2016. The 31 IRTAD member countries registered a 3.3% increase in road fatalities in 2015 compared to 2014. Finally, in 2016, the number of fatalities increased in 14 countries. 

European Commission launched a report following the C-ITS Platform Phase I report from January 2016 and addresses the common technical and legal framework necessary for the deployment of C-ITS and also takes the needs and possibilities of higher levels of automation into consideration. Following an invitation of the European Commission, industry representatives and public authorities have agreed on a further developed shared vision on the inter-operable deployment of Cooperative Intelligent Transport Systems (C-ITS) towards cooperative, connected and automated mobility (CCAM) in the European Union.  

A paper titled “Comparative assessment of the behaviour of drivers with Mild Cognitive Impairment or Alzheimer’s disease in different road and traffic conditions” authored by Dimosthenis Pavlou, Eleonora Papadimitriou, Costas Antoniou, Panagiotis Papantoniou, George Yannis, John Golias and Sokratis G. Papageorgiou, is now published in Transportation Research Part F: Traffic Psychology and Behaviour, Volume 47, May 2017, pp. 122-131. The objective of this research was the analysis of the driving performance of drivers with Mild Cognitive Impairment (MCI) or Alzheimer’s disease (AD), in different road and traffic conditions, on the basis of a driving simulator experiment. The results of this research suggest that compensatory behaviours developed by impaired drivers are not adequate to counterbalance the direct effects of these cerebral diseases on driving skills. They also demonstrate that driving impairments increase as cognitive impairments become more severe (from MCI to AD). 

A Diploma Thesis titled “Analysis of the effect of economic recession on road safety in Greece” was presented by Christos Batsos in September 2017. For this analysis, suitably processed road accident data during the period 2003-2014 have been exploited. It appears that the economic recession has led to a significant reduction in fatalities and serious injuries. The principal mechanisms bringing this decline about are the reduction of accidents with involvement of passenger cars, of young drivers and outside traffic junctions. These results indicate that apart from the decline of vehicle kilometers of travel, changes in road user behaviour might have contributed significantly to the overall improvement of road safety during the economic crisis.  

A Diploma Thesis titled “Modelling mobile phone use impact on driver behaviour through the exploitation of data from smartphone sensors” was presented by Anastasia Argyropoulou in July 2017, with the support and data from OSeven Telematics. The aim of this Diploma Thesis was to examine and model the impact of mobile phone use on driver behaviour through the exploitation of data from smartphone sensors. To achieve this objective, data collected from 100 drivers who participated at a naturalistic driving experiment for four months were analysed through statistical modelling. The application of the models revealed that the factors affecting the harsh events are five, with the average driving speed being the main one, while the factors affecting the possibility of using the mobile phone while driving are six, with the average angular speed being the main one.  

A paper titled “Meta-analysis of the effect of road work zones on crash occurrence” authored by Athanasios Theofilatos, Apostolos Ziakopoulos, Eleonora Papadimitriou, George Yannis, and  Konstandinos Diamandouros is now published in Accident Analysis and Prevention. This paper presents formal meta-analyses of studies that have estimated the relationship between the number of crashes and work zone duration and length, in order to provide overall estimates of those effects on crash frequencies. All studies presented in this paper are crash prediction models with similar specifications. Meta-regression findings indicate that the main factors influencing the overall estimates of the beta coefficients are study year and region for work zone duration and study year and model specification for work zone length.
