EU road safety statistics show small improvement for 2014

The European Commission has published the most recent statistics on road fatalities, based on provisional data for 2014 road deaths in Europe. The number of road fatalities has decreased by approximately only 1% compared to 2013; the decrease rate has slowed down in 2014 following on the 8% decrease in 2012 and 2013. The average EU fatality rate for 2014 is expected to be 51 road deaths per million inhabitants. Country by country statistics show that the number of road deaths still varies greatly across the EU, from less than 30 (Malta, the Netherlands, Sweden and the United Kingdom) to above 90 (Bulgaria, Latvia, Lithuania and Romania) deaths per million inhabitants. 

In the respective accompanying European Commission road safety statistics report, the basic safety trends, statistics and challenges in the EU 2010-2014 are highlighted, with focus on pedestrians, cyclists and motorcyclists.pdf5

Feasibility analysis of installing pedestrian bridges in major road axes in Athens 2015

A Diploma Thesis titled ‘Feasibility analysis of installing pedestrian bridges in major road axes in Athens‘ was presented by Natalia Vraka in March 2015. Sixteen hazardous road locations for the five year period 2007 – 2011, were identified through the Quality Control method, assessing accident data concerning pedestrians and traffic volume data regarding eleven central road axes of Athens with a high pedestrian traffic. Then, a before-and-after accident analysis method with a large control group was applied , which demonstrated a strong dissimilarity between the six examined pedestrian bridges. As a result, no clear conclusions could be drawn about the impact of pedestrian bridges in accidents frequency and severity. However, based on in situ observations made at the 16 dangerous road sections, the conclusion drawn was that there is high potential for the construction of pedestrian bridges in four of them, whereas in four others specific additional interventions would be needed. pdf5 ppt5

Global NCAP – Millions of new cars worldwide fail UN safety standards 2015

The Road Map for Safer Cars 2020 has recently been published by Global NCAP with ten key recommendations for safer cars. Millions of new cars sold in middle and low income countries fail to meet the UN’s basic safety standards for front and side impacts revealed international automotive safety watchdog Global NCAP. A package of minimum safety regulations for adoption by the end of the UN Decade, measures to promote a market for safety among car buyers in the rapidly motorising countries, policies to sustain the safety of the vehicles once in use, and a proposed industry voluntary commitment to implement minimum occupant safety standards to all new passenger cars are included in the Road Map. If this Road Map is followed by 2020, all new cars in the world would pass the minimum UN standards for crashworthiness and crash avoidance. This would spread the advances in automotive safety technology across all countries, mitigate the risks of rapid motorisation, and help achieve a world free from many avoidable and unnecessary road traffic fatalities.

Investigation of the effect of vehicle collision type on road accident severity in Greece – 2015

A Diploma Thesis titled ‘Investigation of the effect of vehicle collision type on road accident severity in Greece‘ was presented by Olga Reitzopoulou in March 2015. Appropriately processed data for the period 2007-2011 in Greece were used from the ELSTAT datafile based on Traffic Police records and special log-rate analysis models were developed. Severity has been chosen to be expressed as the rate of number of persons killed and seriously injured divided by the number of slightly injured persons. The analysis led to the investigation of the impact on accident severity of the area type and the vehicle type involved. It appears that the severity is higher for passenger car and motorcycle occupants, while the vehicle type of the opponent car that affects more the severity is passenger car and truck. This impact is higher outside urban areas. pdf5 ppt5

ETSC – Ranking EU progress on improving motorways safety 2015

The European Transport Safety Council (ETSC) has just published the PIN Flash Report ‘Ranking EU progress on improving mororways safety‘, with the contribution of NTUA. Motorways are the safest roads by design and regulation. Nevertheless in 2013, around 1,900 people were killed on the motorway network in the EU, representing 7% of all road deaths. Nearly 27.500 people have died on motorways in the EU in the last ten years 2004 to 2013. Nevertheless progress has been made. Across the EU the number of people killed on motorways was cut by 49% between 2004 and 2013 (compared to 44% on the rest of the road network). Over the same period, the length of the motorway network increased by about a quarter.

European Commission – Safety-related aspects of tyre use 2014

The European Commission has recently released a Study on some safety-related aspects of tyre use,  prepared by the TNO and TML. The overall aim of the study is to propose policy options concerning the use of tyres for improvement of traffic safety. Centrally to this, is the idea that end users need to make the correct assessment in relation to the tyre condition in order to achieve a level of safety as high as possible. The tyre condition is considered in relation to technical elements (tyre inflation pressure, tyre tread depth, tyre damage, tyre age, and meteorological influences) and one information element (driver awareness). The study addresses the topics of tyre usage and the impact on road safety (which are the potential safety improvements related to tyre usage from a technical perspective) and how can road users be supported to use tyres that have a better safety performance by policy options. pdf5

A review of Powered-Two-Wheeler behaviour and safety – 2014

A paper titled ‘A review of Powered-Two-Wheeler behaviour and safety‘ co-authored by Athanasios Theofilatos and George Yannis is now published in the International Journal of Injury Control and Safety Promotion. Current research on PTW safety is not as extensive as for other road users (passenger cars, etc.) and this research provides a critical review of research on Power-Two-Wheeler behaviour and safety with regard to data collection, methods of analysis and contributory factors, and discuss the needs for further research. Both macroscopic analyses (accident frequency, accident rates and severity) and microscopic analyses (PTW rider behaviour, interaction with other motorised traffic) are examined and discussed in this paper. The research gaps and the needs for future research are identified, discussed and put in a broad framework. When the interactions between behaviour, accident frequency/rates and severity are co-considered and co-investigated with the various contributory factors (riders, other users, road and traffic environment, vehicles), the accident and injury causes as well as the related solutions are better identified.  doi

Simulation of Pedestrians and Motorised Traffic: existing research and future challenges – 2014

A paper titled ‘Simulation of Pedestrians and Motorised Traffic: existing research and future challenges‘ co-authored by Eleonora Papadimitriou, Jean Michael Auberlet, Sylvain Lassarrre and George Yannis is now published in International Journal of Interdisciplinary Telecommunications and Networking. The objective of this paper is the analysis of the state of the art in pedestrian simulation models and the identification of key issues for further research, with particular focus on the modelling of pedestrians and motorised traffic. A review and a comparative assessment of pedestrian simulation models are carried out, including macroscopic models, earlier meso- and miscosimulation models (mostly in Cellular Automata) and more recent Multi-Agent simulation models. The reviewed models cover a broad range of research topics: pedestrian flow and level of service, crowd dynamics and evacuations, route choice etc. However, pedestrian movement in urban areas and the interactions between pedestrians and vehicles have received notably less attention. A number of challenges to be addressed in future research are outlined: first, the need to and account for the hierarchical behavioural model of road users (strategic / tactical / operational behaviour); second, the need for appropriate description and parameterization of vehicle and pedestrian networks and their crossing points; third, the need to exploit in the simulation models the results of statistical and probabilistic models, which offer valuable insight in the determinants of pedestrian behaviour. In each case, recent studies towards addressing these challenges are outlined.  doi

Current road safety trends in Greece – 2014

A paper titled ‘Current road safety trends in Greece‘ co-authored by George Yannis and Alexandra Laiou is now published in Periodica Polytechnica. Greece has been for years among the worst performing countries in Europe in terms of road safety with one of the highest annual rates of fatalities per million inhabitants in the EU. However, a gradual decrease has been recorded over time. The bad performance of Greece in road safety is partially due to institutional problems such as inefficient organization of public administration, lack of organized structures of the State with responsibility for road safety, non-accountability of stakeholders in relation to the implementation of actions and inadequate funding for road safety. The most critical, road user behavior related, accident factors include speeding, low usage rates of seat belts and helmets, unorganized and unprotected traffic of vulnerable road users, drink-driving, use of mobile phones while driving and generalized aggressive driving. In Greece, a great potential for safety improvement exists, if serious effort for tackling the above major critical factors is made. doi

A review of the effect of traffic and weather characteristics on road safety – 2014

A paper titled ‘A review of the effect of traffic and weather characteristics on road safety‘ co-authored by Athanasios Theofilatos and George Yannis is now published in Accident Analysis & Prevention. Taking into consideration the increasing availability of real-time traffic data and stimulated by the importance of proactive safety management, this paper attempts to provide a review of the effect of traffic and weather characteristics on road safety, identify the gaps and discuss the needs for further research. Despite the existence of generally mixed evidence on the effect of traffic parameters, a few patterns can be observed. For instance, traffic flow seems to have a non-linear relationship with accident rates, even though some studies suggest linear relationship with accidents. On the other hand, increased speed limits have found to have a straightforward positive relationship with accident occurrence. Regarding weather effects, the effect of precipitation is quite consistent and leads generally to increased accident frequency but does not seem to have a consistent effect on severity. The impact of other weather parameters on safety, such as visibility, wind speed and temperature is not found straightforward so far. The increasing use of real-time data not only makes easier to identify the safety impact of traffic and weather characteristics, but most importantly makes possible the identification of their combined effect. The more systematic use of these real-time data may address several of the research gaps identified in this research.  doi

The combined effect of economic crisis, traffic and weather conditions on road safety in Athens 2014

A Diploma Thesis titled ‘The combined effect of economic crisis, traffic and weather conditions on road safety in Athens‘ was presented by Eleni Ziaka in July 2014. Data was collected on a monthly basis for the period 2006-2011 in Attica for victims in road accidents (motorcyclists & pedestrians) including rainfall and temperature, traffic volume and speed in selected arterials and police reports (use of seatbelt and helmet, driving under the influence of alcohol and speed limit violations) and six lognormal regression models were developed. Results show that congestion is statistically significant in every model and speed is statistically significant only in models with seriously injured and killed people. Also, it was found that an increase in temperature and decrease in rainfall increases the number of casualties and especially the seriously injured and killed people. Moreover, influence of speed limit violations and driving under the influence of alcohol is statistically significant. Finally, it is seen that there is a decrease trend in the number of casualties during the economic crisis. pdf5 ppt5

Motorcycle riding under the influence of alcohol: Results from the SARTRE-4 survey – 2014

A paper titled ‘Motorcycle riding under the influence of alcohol: Results from the SARTRE-4 survey‘, co-authored by Eleonora Papadimitriou, Athanasios TheofilatosGeorge Yannis, Julien Cestac and Sami Kraïem is now published in Accident Analysis and Prevention. This research investigates the factors affecting the declared frequency of drink-riding among motorcyclists in Europe and explores regional differences. Data were collected from the SARTRE-4 (Social Attitudes to Road Traffic Risk in Europe) survey, which was conducted in 19 countries. A total sample of 4483 motorcyclists was interviewed by using a face-to-face questionnaire. The data were analyzed by means of multilevel ordered logit models. The results revealed significant regional differences (between Northern, Eastern and Southern European countries) in self-reported drink-riding frequencies in Europe. In general,declared drinking and riding were positively associated with gender (males), increased exposure, underestimation of risk, friends’ behaviour, past accidents and alcohol ticket experience. On the other hand, it was negatively associated with underestimation of the amount of alcohol allowed before driving, and support for more severe penalties.   doi

Road safety forecasts in five European countries using structural time-series models -2014

A paper titled ‘Road safety forecasts in five European countries using structural time-series models‘, co-authored by Constantinos AntoniouEleonora Papadimitriou and George Yannis is now published in Traffic Injury Prevention. The objective of this research is toapply structural time series models for obtaining reliable medium- to long-term forecasts of road traffic fatality risk using data from 5 countries with different characteristics from all over Europe(Cyprus, Greece, Hungary, Norway, and Switzerland). Two structural time series models are considered: (1) the local linear trend model and the (2) latent risk time series model. Furthermore, a structured decision tree for the selection of the applicable model for each situation (developed within the Road Safety Data, Collection, Transfer and Analysis

[DaCoTA] research project, co-funded by the European Commission) is outlined. The modeling process included the model selection, the introduction of intervention variables and the development of mobility scenarios. The forecasts using the developed models appear to be realistic and within acceptable confidence intervals. The proposed methodology is proved to be very efficient for handling different cases of data availability and quality, providing an appropriate alternative from the family of structural time series models in each country.  doi

Needs and priorities of road safety stakeholders for evidence-based policy making – 2014

A paper titled ‘Needs and priorities of road safety stakeholders for evidence-based policy making‘ co-authored by Eleonora Papadimitriou and George Yannis is now published in Transport Policy Journal. The objective of this research is the analysis of needs and priorities of road safety stakeholders for evidence-based policy making. Needs and priorities concern both the data to be collected or made available and the tools to be developed or made available to support science-based policy-making. Within the EC co-funded DaCoTA research project, an on-line survey was addressed to more than 3.000 stakeholders, mostly from European countries, in which participants were asked to assess the importance of more than 50 items reflecting data and resources for all stages of road safety policy making. Cluster analysis was carried out, revealing 4 groups of stakeholders with similar needs and priorities: a “low priorities” group, a “need data and models group”, a group mainly interested on “implementation” and an “in-depth analysis” group. Further analysis suggested that the four clusters are adequately – and often similarly – represented in all groups of countries, and in all types of organizations (e.g. national administrations, universities, interest groups, road safety organizations etc.).  doi

Latent risk and trend models for the evolution of annual fatality numbers in 30 European countries – 2014

A paper titled ‘Latent risk and trend models for the evolution of annual fatality numbers in 30 European countries‘ co-authored by Emmanuelle Dupont, Jacques J.F. Commandeur, Sylvain Lassarre, Frits Bijleveld, Heike Martensen, Constantinos Antoniou, Eleonora Papadimitriou, George Yannis, Elke Hermans, Catherine Pérez, Elena Santamariña-Rubio, Davide Shingo Usami,Gabriele Giustiniani is now published in Accident Analysis & Prevention. In this paper a unified methodology is presented for the modelling of the evolution of road safety in 30 European countries. For each country, annual data of the best available exposure indicator and of the number of fatalities were simultaneously analysed with the bivariate latent risk time series model. This model is based on the assumption that the amount of exposure and the number of fatalities are intrinsically related. It captures the dynamic evolution in the fatalities as the product of the dynamic evolution in two latent trends: the trend in the fatality risk and the trend in the exposure to that risk. The temporal structure of the unobserved components of the optimal model was established, and structural breaks in the trends related to external events were identified and captured by adding intervention variables to the appropriate components of the model. As a final step, for each country the optimally modelled developments were projected into the future, thus yielding forecasts for the number of fatalities up to and including 2020.  doi

Impact of texting on young drivers’ behaviour and safety in urban and rural roads through a simulation experiment – 2014

A paper titled ‘Impact of texting on young drivers’ behaviour and safety in urban and rural roads through a simulation experiment‘ co-authored by George Yannis,Alexandra Laiou, Panagiotis Papantoniou and Charalambos Christoforou is now published in Journal of Safety Research. A driving simulator experiment was carried out in which 34 young participants drove in different driving scenarios; specifically, driving in good weather, in raining conditions, in daylight and in night were examined. Lognormal regression methods were used to investigate the influence of texting as well as various other parameters on the mean speed and mean reaction time. Binary logistic methods were used to investigate the influence of texting use as well as various other parameters in the probability of an accident. It appears that texting leads to statistically significant decrease of the mean speed and increase of the mean reaction time in urban and rural road environment. Simultaneously, it leads to an increased accident probability due to driver distraction and delayed reaction at the moment of the incident. It appeared that drivers using mobile phones with a touch screen present different driving behavior with respect to their speed, however, they had an even higher probability of being involved in an accident.  doi

Modeling road accident injury under-reporting in Europe – 2014

A paper titled ‘Modeling road accident injury under-reporting in Europe‘ co-authored by George YannisEleonora Papadimitriou, Antonis Chaziris and Jeremy Broughton is now published in European Transport Research Review. The purpose of this research is to present a disaggregate analysis of road accident injury under-reporting in selected European countries. The level of injury under-reporting is expressed by under-reporting coefficients, estimated as the actual estimated number of road accident injuries of a given severity to the number of related injuries recorded by the Police. Log-rate models are developed in order to estimate the combined effects of country (CZ, FR, GR, HU, NL, ES and the UK), road user type (car occupant, motorcyclist, pedal cyclist, pedestrian), Police severity score (serious or slight injury) and MAIS score (the maximum Abbreviated Injury Scale score) on under-reporting. The results suggest that the examined characteristics have important combined effect on under-reporting (i.e. third-order interaction). For example, it was found that slight injuries are more likely to be under-reported than serious injuries in the Czech Republic, France, and Greece, while the opposite is the case for the Netherlands and the UK. Moreover, although the Netherlands do not present high under-reporting rates overall, a particular issue is identified in this country for pedal cyclists’ slight injuries.  doi

Comparative multilevel road safety analysis in European capitals 2014

A Diploma Thesis titled ‘Comparative multilevel road safety analysis in European capitals‘ was presented by Marianthi Mermygka in May 2014. A database was developed for this analysis containing data regarding the number and the characteristics of road fatalities, the population and other indicators of the nine selected European capital cities for the period 2007 – 2011. Multilevel Poisson statistical models were developed, allowing for a clearer picture of the hierarchical structure of road safety data, and they led to a more complete identification of factors affecting road safety level in the selected European capital cities, revealing new additional aspects of road safety performance in these cities. Factors found with a statistically significant impact concerned city characteristics (road network length, population density, public transport use) and accident characteristics (road user and vehicle type). The comparison between the European capital cities showed that the larger the city’s road network is, the higher the level of road safety is in this citypdf5 ppt5

ETSC – 12.000 car occupant fatalities in EU in 2012

In April 2014, the European transport Safety Council (ETSC) published in its re-designed website a PIN Flash concerning Car Occupant Safety. Around 240,000 car occupants were killed in road collisions in the EU in the years 2001-2012 . There were 12,345 deaths in 2012 compared with 27,700 in 2001, a cut of 55%. Deaths of car occupants were cut by more than the overall death rate (49%) and substantially more than the rate for other road users (41%). Car occupants have therefore benefitted more than other road users from road safety measures adopted over the past decade. This is not surprising, as many of those measures were targeted at car occupants including increased enforcement of the main traffic offences, improved vehicle occupant protection, and, to a lesser extent, improved infrastructure.

Relationship between motorcyclists’ attitudes, behaviour and other attributes with declared accident involvement in Europe – 2014

A paper titled ‘Relationship between motorcyclists’ attitudes, behaviour and other attributes with declared accident involvement in Europe‘ co-authored by Athanasios Theofilatos and George Yannis is now published in Traffic Injury Prevention. The objective of this study is to investigate patterns of road safety attitudes and behaviors of motorcyclists in Europe on the basis of the results of the pan-European questionnaire-based survey SARTRE-4, carried out in late 2010 in 18 European countries and Israel. It was found that motorcyclists who tend to have dangerous attitudes and behaviors as well as younger motorcyclists are more likely to have been involved in an accident. The findings of the study provide some insight into the association between attitudes, behaviors, and declared past accident involvement.  doi

Assessment of exposure proxies for macroscopic road safety prediction 2013

A paper titled ‘Assessment of exposure proxies for macroscopic road safety prediction‘ co-authored by Costas Antoniou and George Yannis is now published in Transportation Research Record. The objective of this research is to investigate the suitability of alternative proxy variables for macroscopic road safety modeling, using three suitable exposure proxies: (i) number of vehicles in circulation, (ii) GDP and (iii) fuel consumption. Severalstructural time-series models have been developed for each proxy for two Mediterranean countries with many similar socio-economic characteristics: Greece and Cyprus. Based on the findings of this analysis, a number of observations can be drawn. Proxy variables can provide reasonable results, when exposure data are not available. Furthermore, even in two countries with many similarities the selected proxy measure differs. This suggests that the underlying conditions that make a variable a suitable proxy for exposure is complex and needs further investigation.  doi

Comparative analysis of young drivers’ behaviour in normal and simulated conditions in interurban road 2014

A Diploma Thesis titled ‘Comparative analysis of young drivers’ behaviour in normal and simulated conditions in interurban road‘ was presented by Marios Nikas in January 2014. This Diploma Thesis aims to compare the behavior of young drivers in normal and simulated driving conditions. Data were collected through an experimental process on a driving simulator but also on real traffic conditions, in which all the participants drove in both cases the same driving scenarios. Lognormal regression methods were developed for the identification of the impact of driving environment (simulated and real traffic conditions), basic driver characteristics (mileage, age, gender), as well as the driving style (average acceleration, deceleration and standard deviations of them) to the average vehicle speed change. Through model implementation, it was revealed that absolute values of drivers’ traffic performance vary between simulated and real driving conditions. On the contrary, relative differences of driver behaviour at the two driving environments remain mostly the same. More precisely, speed difference between fast and slow drivers is the same at the two driving environments, as is also speed difference the same at the two driving environments between drivers talking and not talking to the co-driver. pdf5 ppt5

Critical factors of motorcycle accidents in Greece 2014

A Diploma Thesis titled ‘Critical Factors of motorcycle accidents in Greece‘ was presented by Evita Alevizou in January 2014. For this thesis, appropriately processed data were used from the database of the Department of Transportation Planning and Engineering of the National Technical University of Athens (NTUA) and loglinear  regression models were developed. The application of these models led to the investigation of the influence of several parameters, such as region type, age, lighting, accident type etc on the number of fatalities and injuries. It appears that the number of vehicles involved in the accident is the most important factor of the fatalities model, while the accident type affects more the serious and slight injuries. This influence is greater on motorcycles than passenger cars. pdf5 ppt5

Comparative analysis of factors affecting driving under the influence of alcohol of car drivers and motorcyclists 2014

A Diploma Thesis titled ‘Comparative analysis of factors affecting driving under the influence of alcohol of car drivers and motorcyclists‘ was presented by Dimitra Arvaniti in January 2014. The aim of this diploma thesis is to examine the factors affecting driving under the influence of alcohol of car drivers and motorcycles. To achieve this goal, the responses of a representative sample of Greek drivers of cars and motorcycles are examined from thepan-European research SARTRE 4 and are analyzed by the development of logistic regression models. The application of the models revealed that the factors affecting driving under the influence of alcohol are six for car drivers and seven for motorcyclists, four of which are common. The common parameters are: age, their opinion on whether most of their friends would be driving under the influence of alcohol, their opinion on whether a person is capable of driving carefully in case of consumption alcohol and their education level. Additional factors for car drivers are their view on the legal limit of alcohol consumption and their gender, and for motorcyclists it is their view on how dangerous driving under the influence of drugs is. pdf5 ppt5

Investigation of the impact on road safety of increasing the speed limit on motorways 2014

A Diploma Thesis titled ‘Investigation of the impact on road safety of increasing the speed limit on motorways‘ was presented by Eleni Georgiadou in January 2014. The objective of this Diploma Thesis is to investigate the impact on road safety of increasing the speed limit on motorways from 120 to 130 km/h in June 2007. In order to achieve this objective, data was collected concerning road accidents on motorway sections Athens – Thebes and Athens – Tripoli from the database of Department of Transportation Planning and Engineering of the N.T.U.A. with data from the Hellenic Statistical Authority and on sections of the Egnatia Motorway from Egnatia Odos S.A. for the period 2005 – 2010. The application of the methodology indicates a statistically significant increase in the number of deaths in the section Athens – Thebes a year after raising the speed limit, possibly due to the increase of the speed limit, and then ceases to be statistically significant, probably due to improvements made to the infrastructure. In the section Athens – Tripoli a reduction in accidents and victims is indicated probably due to improvements in the infrastructure while in the Egnatia Motorway there is no statistically significant change possibly due to the high geometrical characteristics of the road which might satisfy the higher speed limit. pdf5 ppt5

EU includes urban road safety in urban mobility package 2013

The European Commission is stepping up its support to towns and cities in the new “Urban Mobility Package”. The European Commission will reinforce the exchange of best practice, with the communication as central element of the urban mobility package: “Together towards competitive and resource-efficient urban mobility“.
One of the four basic priorities of the Urban Mobility Package is to enhance urban road safety and protect in particular the vulnerable users from death and serious injury. The European Commission will continue to gather and disseminate good practice examples for road safety planning and consider further measures for reducing the number of serious road traffic injuries in urban areas. Member States should ensure that sustainable urban mobility plans give due consideration to urban road safety as a horizontal issue.

ERF – Road Markings save lives and money 2013

The European Union Road Federation (ERF) has launched a Position Paper that makes the case for a more widespread use of road markings on Europe’s roads as a means of increasing road safety and reducing the socio-economic impact of accidents. Road markings are one of the most cost-effective safety solutions that are available to policymakers and road owners. They provide drivers with much needed guidance on the road, allow for better preview time and can significantly help avert the risks of run-off accidents and head-collisions. This paper is calling on Member States to establish intervention and maintenance policies to guarantee that road markings on Europe’s road remain visible for first and foremost for road users and at same time, optimise the interaction between the road infrastructure and the intelligent car. pdf5

Detecting Powered-Two-Wheeler Incidents from High Resolution Naturalistic Data 2014

A paper titled ‘Detecting Powered-Two-Wheeler Incidents from High Resolution Naturalistic Data‘ co-authored by Eleni Vlahogianni, George Yannis and John Golias is now published in Transportation Research Part F: Traffic Psychology and Behaviour. During risky conditions, Powered-Two-Wheeler (PTW) drivers often alter their behavior from a regular driving pattern to an irregular chain of driving actions by braking, changing the throttle pressure, maneuvering and so on, or combinations of the above. However, both the actual and perceived thresholds of regular and irregular driving behavior differ among PTW drivers. A simple and flexible methodology is proposed in order to define PTW driving profiles by distinguishing between regular and irregular PTW driving behaviors using high resolution naturalistic data. “Irregularities” in driving behavior are consistently expressed as outlying values in the dataset of driving parameters. The detected irregularities are those that diverge from the centroid of the jointly considered driving parameters. These irregularities may be considered to define critical driving situations (incidents) that are further associated to typical driving events. Results indicate that the joint consideration ofvariables which are directly connected to the mechanical characteristics of PTW, such as front and rear brake activation, wheel speed, throttle and steering, are adequate to distinguish the regular from irregular PTW driving behavior.  doi

Effect of GDP changes on road traffic fatalities 2013

A paper titled ‘Effect of GDP changes on road traffic fatalities‘ co-authored by George Yannis, Eleonora Papadimitriou and Katerina Folla is now published in the Journal of Safety Science. This research aims to associate annual Gross Domestic Product (GDP) changes with the related annual changes in road traffic mortality rates. Mortality rates and GDP per capita data for the period 1975–2011 are used from 27 European countries, for the development of mixed linear models. The results suggest that an annual increase of GDP per capita leads to an annual increase of mortality rates, whereas an annual decrease of GDP per capita leads to an annual decrease of mortality rates. These effects are statistically significant overall, and in different groups of countries (Northern/Western, Central/Eastern and Southern). A one-year lagged effect of annual GDP decrease was found to be significant in Northern/Western countries.  doi

Exposure data and risk indicators for safety performance assessment in Europe 2013

A paper titled ‘Exposure data and risk indicators for safety performance assessment in Europe‘ co-authored by Eleonora Papadimitriou, George Yannis, Frits Bijleveld and João Cardoso is now published in the Journal of Accident Analysis and Prevention. The objective of this paper is theanalysis of the state-of-the-art in risk indicators and exposure data for safety performance assessment in Europe, in terms of data availability, collection methodologies and use. More specifically, the concepts of exposure and risk are explored, as well as the theoretical properties of various exposure measures used in road safety research (e.g. vehicle- and person-kilometres of travel, vehicle fleet, road length, driver population, time spent in traffic, etc.). Moreover, the existing methods for collecting disaggregate exposure data for risk estimates at national level are presented and assessed, including survey methods (e.g. travel surveys, traffic counts) and databases (e.g. national registers). A detailed analysis of the availability and quality of existing risk exposure data is also carried out. Finally, the potential of international risk comparisons is investigated, mainly through the International Data Files with exposure data (e.g. Eurostat, IRTAD, ECMT, UNECE, IRF, etc.). The results of this review confirm that comparing risk rates at international level may be a complex task, as the availability and quality of exposure estimates in European countries varies significantly. The lack of a common framework for the collection and exploitation of exposure data limits significantly the comparability of the national data. On the other hand, the International Data Files containing exposure data provide useful statistics and estimates in a systematic way and are currently the only sources allowing international comparisons of road safety performance under certain conditions.  doi

Multilevel analysis in road safety research 2013

A paper titled ‘Multilevel analysis in road safety research‘ co-authored by Emmanuelle Dupont, Eleonora Papadimitriou, Heike Martensen and George Yannis is now published in the Journal of Accident Analysis and Prevention. This paper summarizes the statistical and conceptual background and motivations for multilevel analyses in road safety research. It then provides a review of several ML analyses applied to aggregate and disaggregate (accident) data. In each case, the relevance of ML modelling techniques is assessed by examining whether ML model formulations (i) allow improving the fit of the model to the data, (ii) allow identifying and explaining random variation at specific levels of the hierarchy considered, and (iii) yield different (more correct) conclusions than single-level model formulations with respect to the significance of the parameter estimates. The evidence reviewed offers different conclusions depending on whether the analysis concerns aggregate data or disaggregate data. In the first case, the application of ML analysis techniques appears straightforward and relevant. The studies based on disaggregate accident data, on the other hand, offer mixed findings: computational problems can be encountered, and ML applications are not systematically necessary. The general recommendation concerning disaggregate accident data is to proceed to a preliminary investigation of the necessity of ML analyses and of the additional information to be expected from their application.  doi

Road safety in bits and pieces by Henk Stipdonk 2013

SWOV Senior Researcher Henk Stipdonk defended recently his PhD Thesis at Delft University of Technology, exploiting also findings from the EC co-funded research projects SafetyNet and Dacota. This Thesis, titled ‘Road safety bits and pieces: for a better understanding of the development of the number of road fatalities‘, focuses on the subdivision (stratification) of the crash data and the data of distance travelled. Different subgroups with different risks (like different travel modes, different age groups and combinations of both) are modelled separately. It is shown that these groups often have different risks and different trends in distance travelled. These different subgroups – the ‘bits’ and ‘pieces’ – and their different developments can give rise to a substantial change in the total risk – the ‘road safety’. It is concluded that the present manner of analyzing road safety developments – i.e. based on the total number of road fatalities and the total fatality rate – is insufficient to achieve a thorough understanding of these developments. It is better to divide the total number of road fatalities into subgroups and to investigate for each individual subgroup which factors influenced road safety. pdf5

Is road safety management linked to road safety performance? 2013

A paper titled ‘Is road safety management linked to road safety performance?‘ co-authored by Eleonora Papadimitriou and George Yannis is now published in the Journal of Accident Analysis and Prevention. Quasi-Poisson models and Beta regression models are developed for linking road safety management indicators (estimated on the basis of Categorical Principal Component Analysis ) and other indicators (i.e. background characteristics, etc.) with road safety performance (mortality and fatality rates, SPIs, composite indicators, etc.).

The results of the analyses suggest that road safety management can be described on the basis of three composite indicators: “vision and strategy”, “budget, evaluation and reporting”, and “measurement of road user attitudes and behaviours”. More-over, no direct statistical relationship could be established between road safety management indicators and final outcomes. However, a statistical relationship was found between road safety management and SPIs, which were in turn found to affect ‘final’ outcomes, confirming the SUNflower approach on the consecutive effect of each layer.  doi

Investigation of the Impact of Low Cost Engineering Measures on Road Safety in Urban Areas 2013

A paper titled ‘Investigation of the Impact of Low Cost Engineering Measures on Road Safety in Urban Areas‘ co-authored by G.Yannis, A.Kondyli and X.Georgopoulou is now published in International Journal of Injury Control and Safety Promotion. This paper investigates the impact of low cost traffic engineering measures (LCTEMs) on the improvement of road safety in urban areas. A number of such measures were considered, such as speed humps, woonerfs, raised intersections and other traffic calming measures, which have been implemented on one-way, one-lane roads in the Municipality of Neo Psychiko in the Greater Athens Area. The application of the methodology showed that the total number of crashes presented a statistically significant reduction, which can be possibly attributed to the introduction of LCTEMs.  doi

Explaining the road accident risk: weather effects 2013

A paper titled ‘Explaining the road accident risk: weather effects‘ co-authored by R.Bergel-Hayat, M.Debbarh, C.Antoniou and G.Yannis is now published in Accident Analysis and Prevention Journal. This research is based on some case studies carried out within the data analysis and synthesis activities of the EU-FP6 project “SafetyNet – Building the European Road Safety Observatory”, which illustrate the use of weather variables for analysing changes in the number of road injury accidents. Time series analysis models with explanatory variables that measure the weather quantitatively were used and applied to aggregate datasets of injury accidents for France, the Netherlands and the Athens region, over periods of more than twenty years. The main results reveal significant correlations on a monthly basis between weather variables and the aggregate number of injury accidents, but the magnitude and even the sign of these correlations vary according to the type of road (motorways, rural roads or urban roads).  doi

Acceptability of rider assistive systems for powered two-wheelers 2013

A paper titled ‘Acceptability of rider assistive systems for powered two-wheelers‘ co-authored by V.Beanland, M.Lenné, E.Fuessl, M.Oberlader, S.Joshi, T.Bellet, A.Banet, L.Rößger, L.Leden, I.Spyropoulou, G.Yannis, H.Roebroeck, J.Carvalhais and G.Underwood is now published in Transportation Research Part F: Traffic Psychology and Behaviour. This study aims to understand general and system-specific factors that are likely to influence acceptability of PTW assistive systems, including barriers that may prevent uptake and proper use of systems, through a large-scale survey of European riders. The survey was available in seven languages and attracted 6297 respondents. Respondents were frequent riders, who rode primarily for leisure purposes and had high awareness of assistive systems. Overall acceptability was low, but riders who perceive greater risk in riding display higher acceptability. In general, riders believe that existing safety equipment (e.g., helmets, protective clothing) is more reliable, provides greater resistance, and is considerably cheaper than more sophisticated assistive technology. doi

State-space based analysis and forecasting of macroscopic road safety trends in Greece 2013

A paper titled ‘State-space based analysis and forecasting of macroscopic road safety trends in Greece‘ co-authored by Constantinos Antoniou and George Yannis from NTUA, is now published in Accident Analysis and Prevention Journal. In this paper, macroscopic road safety trends in Greece are analyzed using state-space models and data for 52 years (1960–2011). Alternative considered models are presented and discussed, including diagnostics for the assessment of their model quality and recommendations for further enrichment of this model. Important interventions were incorporated in the models developed (1986 financial crisis, 1991 old-car exchange scheme, 1996 new road fatality definition) and found statistically significant. Furthermore, the forecasting results using data up to 2008 were compared with final actual data (2009–2011) indicating that the models perform properly, even in unusual situations, like the current strong financial crisis in Greece. Forecasting results up to 2020 are also presented and compared with the forecasts of a model that explicitly considers the currently on-going recession.  doi

Investigating the self-reported behavior of drivers and their attitudes to traffic violations 2013

A paper titled ‘Investigating the self-reported behavior of drivers and their attitudes to traffic violations‘ co-authored by Sophia Vardaki and George Yannis is published in the Journal of Safety Research. A sample of 601 Greek drivers participating at the SARTRE 4 pan-European questionnaire-based survey is exploited. The findings indicate that differences in attitudes and behaviours may be attributed to factors such as age, gender, and area of residence. The research findings also provided some insight about the current level of drivers’ attitudes to traffic violations, especially those that negatively affect traffic safety. The pattern of their views on violations may form the basis of risk behavior-related interventions tailored to the identified groups, aiming at informing, educating, and raising the awareness of the public. doi

Multilevel analysis of road accident characteristics in urban areas in Europe 2013

A Diploma Thesis titled ‘Multilevel analysis of road accident characteristics in urban areas in Europe‘ was presented by Eleftheria Choustoulaki in March 2013. For this analysis a database was developed containing, road fatalities, characteristics of the driver, the road environment and the vehicle, GDP per capita, population in urban areas and vehicle fleet for 24 European countries for the year 2009. The results led to the conclusion that the use of hierarchical data structures and nested data structures, for data concerning accident in urban areas of Europe is necessary for the correct estimation of the parameters impact. From the second level analysis a differentiation in the number of fatalities in the various European urban areas was found, depending on the specific characteristics of these areas. Moreover the application of these models led to the identification of the impact of various parameters such as weather conditions, vehicle type, fatality age on the number of fatalities in the various urban areas of the European countries. pdf5 ppt5

Investigation of factors affecting helmet use among European motorcyclists 2013

A Diploma Thesis titled ‘Investigation of factors affecting helmet use among European motorcyclists‘ was presented by Christos Katrakazas in March 2013. Αn analysis took place, based on data from the SARTRE 4 Pan-European survey, which was conducted on a representative sample of European motorcycle drivers. Binary Logistic regression models were developed to investigate factors affecting helmet use on four types of roads (motorways, main roads between towns, country roads and built-up areas). These models were used on the samples from Greece, Europe as a whole, three groups of countries (Northwest, South and East) and three representative countries. According to the results from the models application, the main characteristic of the motorcyclists who are more likely to wear helmet, is that they fasten it frequently. On the contrary, the main factor that decreases the probability of a motorcyclist to wear helmet is helmet usage only because it is mandatory by law. pdf5 ppt5

Correlation of traffic characteristics with road accident severity and probability 2013

A Diploma Thesis titled ‘Correlation of traffic characteristics with road accident severity and probability‘ was presented by Apostolos Ziakopoulos in March 2013. Data concerning the road accidents occurred on Kifisias Avenue in Athens, Greece, during the period 2006 – 2010 were collected from the ELSTAT database with disaggregate data. Subsequently, traffic data (volume, speed, occupation) were obtained from the Traffic Management Centre of Athens. For the analysis, logistic regression mathematical models were developed. The application of these models indicates that road accident severity is correlated with the logarithm of traffic density, the type of vehicle and the type of accident. When data are separated in two groups of peak and off-peak hour accidents, the parameter of traffic density is the only one appearing to be statistically significant. Furthermore, traffic volume is the only parameter found with a statistically significant impact on accident probability. pdf5 ppt5

Multilevel investigation of road accident characteristics in Greek cities 2013

A Diploma Thesis titled ‘Multilevel investigation of road accident characteristics in Greek cities‘ was presented by Dimitris Spanakis in March 2013. For this analysis, a database was developed with road accident data from the Hellenic Statistical Authority in 30 Greek cities for the period 2006-2010, which has been complemented with cities demographic data: population, vehicle fleet, and per capita income. From the results, useful conclusions are deducted for the impact of some of the examined parameters in the number of fatalities, serious and slight injuries in Greek cities, such as existence of median, operation of technical night lighting, accident type, vehicle type, casualty age and vehicle fleet. From the second level analysis it was found that there is significant variation of the impact of the vehicle fleet of each city to the number of casualties in road accidents, which was quantified. pdf5 ppt5

European Commission announces serious injury common definition 2013

The European Commission published a Report on the first steps taken towards achieving reduction of serious road traffic injuries, which is one of the seven strategic objectives set by the Commission in 2010 in its road safety policy orientations for the period 2011-2020.

The document looks at what has been done so far and describes the problem of serious road traffic accidents and the challenges of the current framework. It considers the situation regarding a common definition of serious injuries, data collection methods and a possible future EU-level target. The use of an established medical classification standard is seen as preferable and the existing trauma scale ‘Maximum Abbreviated Injury Score’ (MAIS) was put forward, with serious injuries defined as those with an MAIS score of 3 or higher, as proposed by the EC research project SafetyNet and the ITFpdf5

Effects of lighting on frequency and severity of road accidents 2013

A paper titled ‘Effects of lighting on frequency and severity of road accidents‘ co-authored by George Yannis, A.Kondyli and N.Mitzalis is now published in the Proceedings of the ICE – Transport. A total of 358.485 police-recorded accidents were analysed and the proposed models were developed with the use of log-normal regression. The application of these models allowed the investigation of the influence of road lighting and other parameters such as weather conditions, accident type and vehicle type on the number of casualties and injuries. It appears that road lighting contributes to the reduction of the number of accidents and their severity and that this influence increases with the increase of the severity of the accidents. The absence of street lighting during nighttime has the highest impact on the number of fatalities and serious injuries. The results show that nighttime lighting has great potential in improving traffic safety and reducing the accident severity, especially for persons killed and seriously injured.  doi

WHO European Road Safety Facts Report 2013

The World Health Organization (WHO) released the European Facts and Global Status Report on Road Safety 2013, prepared by Francesco Mitis and Dinesh Sethi. This European Facts Report provides a baseline assessment to what extent countries in the 51 countries of the WHO European Region are implementing effective road safety measures to address the five key risk factors: drinking and driving, speeding, helmets, seat-belts and child restraints.

Though death rates are down, the Report shows that 55% of the European population live in countries that do not provide the protection of comprehensive road safety laws. It also highlights the importance of issues such as vehicle safety standards, road infrastructure inspections and policies on walking and cycling. In charts, maps and tables, the brief report presents information from 51 countries, covering most of the population of the Region, and providing a baseline assessment to measure progress towards the goals of the Decade of Action for Road Safety 2011–2020.

Why do drivers exceed speed limits 2013

A paper titled ‘Why do drivers exceed speed limits‘ co-authored by G.Yannis, G.Louca, S.Vardaki and G.Kanellaidis is published in the European Transport Research Review. The purpose of this study is to explore relationships between drivers’ attitude towards exceeding speed limits in different types of road and the drivers’ characteristics and self-reported speed behaviour.Loglinear analysis was used and four models were developed: for motorways, main roads, country roads and built-up area roads. The model application revealed that the dependent variable (self-reported exceeding the speed limit) is strongly dependent on the belief that other drivers exceed speed limits for all four road types.  doi

Critical power two wheeler driving patterns at the emergence of an incident 2013

A paper titled ‘Critical power two wheeler driving patterns at the emergence of an incident’ co-authored by Eleni Vlahogianni, George Yannis and John Golias is now available in the Accident Analysis and Prevention Journal. The paper proposes a methodology based on Bayesian Networks for identifying the power two wheeler (PTW) driving patterns that arise at the emergence of a critical incident based on high resolution driving data (100 Hz) from a naturalistic PTW driving experiment. Results using data from one PTW driver reveal three prevailing driving actions for describing the onset of an incident and an equal number of actions that a PTW driver executes during the course of an incident to avoid a crash.  doi

Reaction times of young alcohol-impaired drivers 2013

A paper titled ‘Reaction times of young alcohol-impaired drivers’ co-authored by Z.Christoforou, M.Karlaftis and G.Yannis is now available at the Accident Analysis and Prevention Journal. The paper focuses on young individuals who drive under the influence of alcohol and are having a higher relative risk of crash involvement; as such, the literature has extensively investigated the factors affecting such involvement through both post-accident surveys and simulator experiments. The results suggested that increased reaction times before consuming alcohol strongly affect post-consumption reaction times, while increased BrAC levels prolong reaction times, a 10% increase in BrAC levels results in a 2% increase in reaction time. Moreover, individuals with faster alcohol absorption times perform better regardless of absolute BrAC level, while recent meals lead to higher reaction times and regular exercising to lower reaction times.  doi

Mobile phone use and traffic characteristics 2013

A paper titled ‘Mobile phone use and traffic characteristics‘ co-authored by G.Yannis, E.Papadimitriou, P.Papantoniou and N.Petrellis is just published in the Traffic Engineering & Control Journal. The objective of this research is the analysis of the impact of mobile phone use on vehicle traffic speed and headways. It was found that vehicle speed is increased for young drivers (aged 18-25 years), male drivers and taxi drivers, and decreased for older drivers (>55 years) and for drivers using their mobile phone while driving. Vehicle’s time headways were not found to be affected by cell phone use. However, headspaces, estimated as the product of vehicle speed and time headways, were found to be decreased for drivers using their mobile phone, young drivers and older drivers.

Road Injuries Consultation Report by the European Commission 2013

The Road Injuries Consultation Report of the European Commission is now available. The public consultation was launched as part of an initiative to reduce the number and the severity of road traffic injuries. This initiative is one of the strategic objectives outlined in the Policy Orientations on Road Safety 2011-2020, and a priority for EU action. Accordingly, the European Commission is developing a comprehensive strategy of action concerning road traffic injuries, with the assistance of relevant actors. The findings of the public consultation clearly indicate that road safety is regarded as a priority on the political agenda. Target setting and support of exchange of best practises are seen as the two areas with the highest EU added value, while research and project funding, legislation and data analysis are following slightly behind. pdf5

Road safety performance indicators for the interurban road network 2012

A paper titled ‘Road safety performance indicators for the interurban road network‘ co-authored by G.Yannis, W.Weijermars, V.Gitelman, M.Vis, A.Chaziris, E.Papadimitriou and Azevedo C. is published in the Accident Analysis and Prevention Journal. This paper presents a theoretical concept for the determination of this SPI as well as a translation of this theory into a practical method. Also, the method is applied in a number of pilot countries namely the Netherlands, Portugal, Greece and Israel. The results show that the SPI could be efficiently calculated in all countries, despite some differences in the data sources. In general, the calculated overall SPI scores were realistic and ranged from 81 to 94%, with the exception of Greece where the SPI was relatively lower (67%).  doi

On statistical inference in time series analysis of the evolution of road safety 2012

A paper titled ‘On statistical inference in time series analysis of the evolution of road safety co-authored by J.Commandeur, F.Bijleveld, R.Bergel-Hayat, C.Antoniou, G.Yannis and E.Papadimitriou is published in the Accident Analysis and Prevention Journal. Some commonly used statistical techniques imply assumptions that are often violated by the special properties of time series data, namely serial dependency among disturbances associated with the observations. The objective if this paper is to demonstrate the impact of such violations to the applicability of standard methods of statistical inference, which leads to an under or overestimation of the standard error and consequently may produce erroneous inferences. Moreover, having established the adverse consequences of ignoring serial dependency issues, the paper aims to describe rigorous statistical techniques used to overcome them.  doi

Country Forecasts at the DaCoTA Road Safety Knowledge System 2012

Road Safety Country Forecasts are available at the DaCoTA Road Safety Knowledge System, developed by the EU co-financed project DaCoTA. For 30 European countries (all 27 EU members States, Iceland, Norway and Switzerland), a specially developed common forecasting methodology was adopted, using risk exposure as the most important explaining variable. These country forecasts can be proved useful for road safety policy, as it is important to know in what direction the annual casualties are developing, and how fast this development is expected to go. At the road safety forecasts for Greece prepared by NTUA, the 50 year trend is analysed and road fatalities forecasts scenaria up to 2020 are proposed.

Modelling the spatial variation of road accidents and fatalities in Greece 2012

A paper titled ‘Modelling the spatial variation of road accidents and fatalities in Greece’ co-authored by E.Papadimitriou, V.Ekshler , G.Yannis, S.Lassarre is just published in the Proceedings of ICE – Transport. The paper focuses on the modelling of the spatial variation of road accidents and fatalities in Greece. For that purpose, NUTS-3 road accident and fatalities risk rates are used for the development of CAR and CAR-convolution spatial models. Moreover, two types of neighbourhood structures of the regional road safety data are tested: a basic structure defined according to the road connections between counties and an extended structure defined on the basis of both road and ferry connections between counties. The results suggest that the basic spatial structure accounts for an important part of the variation in road accident rates in the Greek counties, revealing a pattern of risk increase from northern to southern Greece. Spatial effects are also identifiable when considering the extended spatial structure, however without explaining a larger part of the overall variation compared to the basic structure. doi
