ETSC – New EU vehicle safety standards essential to reducing child road deaths, 2018

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.

Simulation based safety margin assessment on speed variation between tangent to curved road alignment, 2018

A paper titled “Simulation based safety margin assessment on speed variation between tangent to curved road alignment” authored by Eleonora Papadimitriou, Stergios Mavromatis, Dimosthenis Pavlou and George Yannis is now published in Advances in Transportation Studies. This paper investigates the safety margins of drivers along tangent to curved road sections. A vehicle dynamics model is presented, allowing to assess the vehicle speed variation at impending skid conditions from tangent to curve on the basis of several parameters. 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 horse power. Higher initial speed was positively correlated with driving efficiency i.e. lower safety margins. On the contrary, a higher safety margin was associated with earlier deceleration before the curvedoi

Analysis of the impact of nighttime driving to young drivers’ behavior and safety in rural roads with the use of driving simulator, 2017

A Diploma Thesis titled “Analysis of the impact of nighttime driving to young drivers’ behavior and safety in rural roads with the use of driving simulator” was presented by Eleftheria Kyriakouli in November 2017 aiming to analyze the impact of nighttime driving on driver behavior and safety in rural areas through a driving simulator experiment. Regression models were developed to analyze the impact of driving at night on the mean speed, on the mean headway distance of the vehicle and the mean reaction time and on the probability of causing an accident. The models’ application demonstrated that nighttime driving leads to small decrease of the mean speed and increase of the mean headway distance of the vehicle, which however cannot outweigh the increase of the mean reaction time in case of an accident and therefore resulting to an increase of accident probabilitypdf5 ppt5

Investigation of the effect of tourism on road accidents, 2017

A Diploma Thesis titled “Investigation of the effect of tourism on road accidents” was presented by Vasileios Bellos in November 2017. The objective of this Diploma Thesis is to investigate the effect of tourism on road accidents. For this purpose, data on road accidents in Greece for the five-year period of 2011-2015 were collected. Negative binomial regression models were developed and it was observed that both the tourist season and tourism as travelling purpose led to an increase in road accidents, with the highest increase being observed in tourist regions. The increase of the relative rate ratio of road accident involvement for foreign tourists in tourist regions may indicate the increased risk of foreign tourists compared to Greek drivers. pdf5 ppt5

Investigation of the impact of weather conditions to young drivers’ behaviour and safety, 2017

A Diploma Thesis titled “Investigation of the impact of weather conditions to young drivers’ behavior and safety in cities with the use of driving simulator” was presented by Maria Chaireti in November 2017. In order to achieve this objective, an experimental process on a driving simulator was carried out and regression models were developed to investigate the impact of weather conditions on the mean speed, the lateral position of the vehicle from the right borderline and the accident probability. The models’ application indicated that driving in the rain contributes to a small reduction in speed, but also to a significant increase in the probability of an accident. When driving in fog, drivers seem to be more cautious, as the lateral position of the vehicle from the right borderlines reduced and the probability of an accident decreased. pdf5 ppt5

Modelling the effect of traffic regimes on safety of urban arterials: the case study of Athens, 2017

A paper titled “Modelling the effect of traffic regimes on safety of urban arterials: the case study of Athens” authored by Athanasios TheofilatosGeorge YannisJohn Golias and Eleni Vlahogianni is now published in Journal of Traffic and Transportation Engineering. To achieve the aims of the study, traffic and accident data during the period 2006–2011 from two major arterials in Athens were collected and processed. Firstly, a finite mixture cluster analysis was implemented to classify traffic into clusters. Afterwards, discriminant analysis was carried out in order to correctly assign new cases to the existing regimes by using a training and a testing set. Lastly, Bayesian logistic regression models were developed to investigate the impact of traffic regimes on accident likelihood and severity. The findings of this study suggest that urban traffic can be divided into different regimes by using average traffic occupancy and its standard deviation, measured by nearby upstream and downstream loop detectors. The results revealed potential specific hazardous traffic conditions. In general, high occupancy values increase accident likelihood, but tend to lead slight accidents, while PTWs are more likely to be involved in an accident, when traffic occupancy is high. Transitions from high to low occupancy also increase accident likelihood. doi

Analysis of the effect of economic recession on road safety in Greece, 2017

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 crisispdf5 ppt5

Mild Cognitive Impairment and driving: Does in-vehicle distraction affect driving performance? – 2017

A paper titled “Mild Cognitive Impairment and driving: Does in-vehicle distraction affect driving performance?” authored by Ion N. BeratisDimosthenis Pavlou, Eleonora PapadimitriouDionysia KontaxopoulouStella FragkiadakiGeorge Yannis, and Sokratis G. Papageorgiou, is now published in Accident Analysis and Prevention. In-vehicle distraction is considered to be an important cause of road accidents. Drivers with Mild Cognitive Impairment (MCI), because of their attenuated cognitive resources, may be vulnerable to the effects of distraction; however, previous relevant research is lacking. The main objective of the current study was to explore the effect of in-vehicle distraction on the driving performance of MCI patients, by assessing their reaction time at unexpected incidents and accident probability, through a driving simulator experiment. Overall, the current findings indicate, for the first time, that a common driving practice, such as the use of mobile phone, may have a detrimental impact on the driving performance of individuals with MCIdoi

Time series and support vector machines to predict Powered-Two-Wheeler accident involvement and accident type, 2017

A paper titled “Time series and support vector machines to predict Powered-Two-Wheeler accident involvement and accident type” co-authored by Athanasios TheofilatosGeorge YannisCostas Antoniou, Antonis Chaziris and Dimitris Sermpis, is now published in Journal of Transportation Safety and Security. This study exploited real-time traffic and weather data from two major urban arterials in the city of Athens, Greece. Due to the high number of candidate variables, a random forest model was applied to reveal the most important variables. Then, the potentially significant variables were used as input to a Bayesian logistic regression model in order to reveal the magnitude of their effect on PTW accident involvement. The results of the analysis suggest that PTWs are more likely to be involved in multi-vehicle accidents than in single-vehicle accidents. It was also indicated that increased traffic flow and variations in speed have a significant influence on PTW accident involvement. doi

Simulation of Texting Impact on Young Drivers’ Behaviour and Safety on Motorways, 2016

A paper titled ‘Simulation of Texting Impact on Young Drivers’ Behaviour and Safety on Motorways‘ co-authored by George Yannis, Alexandra Laiou, Panagiotis Papantoniou and Christos Gkartzonikas is now published in Transportation Research Part F: Traffic Psychology and Behaviour. A driving simulator experiment was carried out, in which 34 young participants drove in different driving scenarios. Results suggest that texting leads to statistically significant decrease of the mean speed and to increased headway in normal and in specific traffic and weather conditions on motorways, as drivers appear to produce compensatory behavior while texting. Furthermore, texting leads to increased accident probability, probably due to longer reaction time of the driver at unexpected incidents.  doi

Comparative analysis of young drivers behaviour in normal and simulated conditions in urban roads, 2017

A Diploma Thesis titled ‘Comparative analysis of young drivers behaviour in normal and simulated conditions in urban roads‘ was presented by Danai Voutsina in March 2017. Data have been selected through an experimental process, in which the participants have driven in real urban conditions and on a driving simulator, while performing different scenarios. By using lognormal regression modelling, the impact of the driving environment, the specific characteristics of each driver as well as the driving style to the average vehicle speed change was investigated. The model application revealed that absolute values of drivers’ traffic performance varies between simulated and real driving conditions. However, speed difference between fast and slow drivers is very much the same at the two driving environments, as is also speed difference between drivers talking and not talking to the co-driver at the two driving environments. pdf5 ppt5

Investigating the acceptance of autonomous vehicles by Greek drivers, 2017

A Diploma Thesis titled ‘Investigating the acceptance of autonomous vehicles by Greek drivers‘ was presented by Charalampos Souris in March 2017. A stated-preference approach was used that included hypothetical scenarios of cost, time, and safety, which were distributed in a specially developed questionnaire. By using models of logistic regression and the respective utility functions it was possible to extract a mathematical description of the drivers’ attitude towards autonomous vehicles. Results show that the Greek drivers attitude is dependent on the cost, time, and level of safety of the autonomous vehicles, the existence of driving support systems (GPS, parking assistant) in their cars today, their opinion on the traffic of autonomous public transport and taxis on the roads, their driving experience, age, and family income. pdf5 ppt5

Investigation of powered 2-wheeler accident involvement in urban arterials by considering real-time traffic and weather data, 2016

A paper titled ‘Investigation of powered 2-wheeler (PTW) accident involvement in urban arterials by considering real-time traffic and weather data‘ co-authored by Athanasios Theofilatos and George Yannis is now published in Traffic Injury Prevention Journal. This study exploited real-time traffic and weather data from two major urban arterials in the city of Athens, Greece. Because of the high number of candidate variables, a random forest model was applied to reveal the most important variables. Then, the potentially significant variables were used as input to a Bayesian logistic regression model in order to reveal the magnitude of their effect on PTW accident involvement. The results of the analysis suggest that PTWs are more likely to be involved in multi-vehicle accidents than in single-vehicle accidents. It was also indicated that increased traffic flow and variations in speed have a significant influence on PTW accident involvement. doi

Does the diagnosis of Alzheimer’s Disease implies immediate revocation of a driving license? – 2016

A paper titled “Does the diagnosis of Alzheimer’s Disease implies immediate revocation of a driving license?” authored by Sokratis G. Papageorgiou, Ion N. Beratis, Dionysia Kontaxopoulou, Stella FragkiadakiDimosthenis Pavlou, and George Yannis is now published in International Journal of Clinical Neurosciences and Mental Health. Based on previous findings, patients with Alzheimer’s Disease (AD) commonly present increased driving difficulties at a level that clearly supports the discontinuation of driving. Nonetheless, some patients with AD, retain adequate driving skills that are similar to those of cognitively intact individuals of similar age, whereas drivers with MCI present an accentuated risk to develop driving difficulties, but their performance is not consistently worse than that of healthy control drivers. Under this perspective this research suggests the need for implementing a personalized approach when taking decisions about the driving competence of drivers with AD and MCI that is based on the effective synthesis of multimodal driving-related indexes by the specialities of neurology, neuro-psychology and traffic engineering. doi

ETSC – Alcohol interlocks and drink driving rehabilitation in the EU 2016

ETSC released a report concerning Alcohol interlocks and drink driving rehabilitation in the EU-Guidelines for Member States. Across Europe there is still a group of hard core drink driving offenders that seem unwilling or unable to change their behaviour despite the use of traditional countermeasures such as awareness campaigns, fines and driving bans. For this group, the introduction of an alcohol interlock programme seems to be an effective measure.

The report consists of three parts: The first provides an overview of the background to the drink driving problem and some traditional countermeasures. The second part profiles alcohol interlock offender programmes from five European countries. The third and final part presents some main practical guidelines for national authorities that are considering an alcohol interlock programme.  pdf5

Innovative motor insurance schemes: A review of current practices and emerging challenges – 2016

A paper titled “Innovative motor insurance schemes: A review of current practices and emerging challenges” authored by Dimitris Tselentis, George Yannis, and Eleni Vlahogianni, is now published in Accident Analysis & Prevention, , with the support and data from OSeven Telematics. The objective of this paper is to provide a review of the most popular and often implemented methodologies related to Usage-based motor insurance (UBI). UBI schemes, such as Pay-as-you-drive (PAYD) and Pay-how-you-drive (PHYD), are a new innovative concept that has recently started to be commercialised around the world. The main idea is that instead of a fixed price, drivers have to pay a premium based on their travel and driving behaviour. There is evidence that UBI implementation would eliminate the cross-subsidies phenomenon, which implies less insurance costs for less risky and exposed drivers. It would also provide a strong motivation for drivers to improve their driving behaviour, differentiate their travel behaviour and reduce their degree of exposure by receiving feedback and monitoring their driving preferences and performance, which would result in crash risk reduction for each driver individually but also for the whole population. doi

UNECE – Draft proposal for a UN Road Safety Fund launched for consultations 2016

A draft proposal for the constitution of a Road Safety Trust Fund was launched for consultations at the first Global Sustainable Transport Conference in Ashgabat. The proposed UN Road Safety Fund will aim at bridging the gaps in the mobilization of adequate resources to fund road safety projects at local, national and global levels. The total additional grant funding for road safety needed to achieve the SDG road safety targets is estimated at $770 million annually over the next decade. The proposed UN Road Safety Fund will serve as a vehicle to leverage additional funding. It is estimated that every $100 million contributed to the Fund would support:

  • the leveraging of $3.4 billion of country and city road safety investment;
  • the saving of 64,000 lives; and
  • the averting of 640,000 serious injuries.

With $770 million of grant funding per year over the coming decade, the proposed UN Road Safety Fund could save 5 million lives and avert 50 million serious injuries in low and middle-income countries.  pdf5

ETSC – Managing Grey Fleet Safety 2016

The European Transport Safety Council (ETSC) has launched a new Report on  Managing Grey Fleet Safety: A Short Guide for Companies Whose Staff Drive Their Own Cars For Work. When a driver uses their own vehicle for work, they are still under the responsibility of the employer, and this presents a real challenge for managing associated work related road safety risk. Employers may think that it is easier to manage employees using their own cars for work, instead of a company car fleet. However once all of the considerations are taken into account this may not be the case. This guide has been produced to assist organisations review and improve grey fleet management, with a specific focus on safety concerns. It will explain the legal responsibilities as well as the business benefits of an effective grey fleet management policy. It will also explain how grey fleet road risks can be reduced through risk assessment, and stress the importance of integrating grey fleet policy in company procedures and management responsibility. link pdf5

European Commission – Serious Road Traffic Injuries Report 2016

The Road Safety Unit of DG Move of the European Commission has recently released a Report titled “Study on Serious Road Traffic Injuries in the EU” prepared by SWOV, Loughborough University and BAST.  According to the European Commission, 135,000 people are seriously injured on European roads every year  and while the number of deaths has fallen dramatically over the last decade, serious injuries have declined at a much slower rate. It is therefore recommended in this study that the EU should set a target to reduce the number of people seriously injured in road collisions.

The new study examined real world collision data and investigation outcomes from across Europe in an attempt to boost understanding of the most common collision situations that result in serious injuries. The data reveal many of the key risk factors and victim profiles which could help member states identify the best measures to reduce such collisions. pdf5

Mobile phone use, speed and accident probability of young drivers – 2016

A paper titled ‘Mobile phone use, speed and accident probability of young drivers‘ authored by George Yannis, Leonidas Roumpas and Eleonora Papadimitriou is now published in Advances in Transportation Studies. A driving simulator experiment was carried out, in which young participants drove in different driving scenarios: urban and interurban areas, good or rainy weather, with or without the occurrence of unexpected incidents. Log-normal linear regression waw used to analyze the influence of mobile phone use and other parameters on the mean speed of drivers, whereas binary logistic regression was used to analyze the influence of mobile phone, change in speed and other parameters on accident probability. The results suggest that mobile phone use leads to statistically significant overall decrease of the mean speed. However, some drivers increased their speed during the mobile phone conversation, a case which has received little attention in the literature. Mobile phone use leads to significant increase of accident probability, indicating that the speed reduction when using a mobile phone is not sufficient to counterbalance the overall increased risk, especially when an unexpected incident occurs. doi

Investigation of declared and revealed driver behaviour using vehicle diagnostics 2016

A Diploma Thesis titled ‘Investigation of declared and revealed driver behaviour using vehicle diagnostics’ was presented by Natalia Vittoratou in July 2016, with the support and data from OSeven Telematics. The aim of this diploma thesis is the correlation of stated and revealed driver’s behavior with the use of vehicle on-board diagnostics (OBD) data. On that purpose, a large data set from a driving behavior experiment was exploited, which recorded continuously (per second during a period of three months) the behaviour of 17 drivers. These data concerned harsh acceleration and braking, average traffic speed and mileage travelled. Drivers’ stated behaviour was investigated through a corresponding questionnaire. For the data analysis, a mathematical statistical model was developed using linear regression. The results demonstrated a strong correlation between harsh brakings and accelerations on one hand and the number of accidents, the annual income and the declared frequency of harsh braking on the other.  pdf5 ppt5

Attitudes of european drivers towards distraction 2016

A Diploma Thesis titled ‘Attitudes of European drivers towards distraction’ was presented by George Vasilakis in July 2016. Responses of a representative sample of 17.000 European drivers are analyzed from the European survey ESRA, conducted in 2015. The analysis of driver behavior is carried out with the use of statistical methods of cluster analysis and negative binomial distribution. Through the method of cluster analysis, four different groups of European countries were ultimately formed with larger and smaller population, high and low income and the characteristics of each group were identified. Τhe results of cluster analysis were used at the negative binomial distribution in which the answers of Europeans to selected questions were summarized in the basic factors describing their driving behavior, the use of mobile phone during driving and their views on issues related to road behaviour of other drivers, the existing measures for road safety, and driver’s distraction.  pdf5ppt5

Correlation of driver characteristics and its safety performance 2016

A Diploma Thesis titled “Correlation of driver characteristics and its safety performance” was presented by Vasiliki Agathangelou in July 2016, with the support and data from OSeven Telematics. Data from an experiment on driver behaviour assessment from an expert was exploited, using on-road driving in conjunction with a self-evaluation questionnaire. The analysis of the drivers’ behaviour was carried out through factor and linear regression analyses. Three groups that characterise drivers’ perception of careless, aggressive and cautious driving behaviour were derived from factor analysis. Moreover, linear regression analysis revealed that driving experience, headways, self-reported driving skills and defensive driving affect positively the overall on-road driving performance score. It was ascertained that driving experience leads to statistically significant increase in overall on-road driving performance score.  pdf5 ppt5

Analysis of aggressive driving characteristics in Greece 2016

A Diploma Thesis titled ‘Analysis of aggressive driving characteristics in Greece‘ was presented by Eva Kalpaxidi in July 2016. The aim of the present Diploma Thesis is the analysis of the characteristics of aggressive driving in Greece exploiting the Pan-European survey of road user’s attitudes: ESRA. Factor Analysis as well as Binary Logistic Regression and Negative Binomial Regression Models were developed in order to demonstrate the correlation between aggressive driving, police checks and the number of accidents caused by aggressive driving. The statistical models developed demonstrated that gender and age play a major role in aggressive driving, the majority of the drivers take positions against speeding and aggressive driving is described by three different characteristics: actions against other drivers, negative feelings and risk-taking actions while driving.  pdf5 ppt5

ETSC – How traffic law enforcement can contribute to safer roads 2016

The European Transport Safety Council (ETSC) has just published the PIN Flash Report ‘How traffic law enforcement can contribute to safer roads‘, with the contribution of NTUA. Exceeding speed limits, drink or distracted driving and failure to wear a seat belt are still the leading causes of death and serious injury on European roads. Excessive or inappropriate speed is a primary factor in about one third of road deaths and an aggravating factor in many more. Drink driving causes as much as 25% of all road deaths in the EU. ETSC estimates that 900 car occupant deaths would have been prevented in 2012 if 99% of those in cars in collisions had been wearing safety belts. Driver distraction, including mobile phone use, is increasingly a factor in fatal collisions. Enforcement of road traffic laws is an essential component in preventing death and injury.

PRACT APM and CMF Repository – May 2016

The PRACT Repository is a new online road safety toolcontaining the most recent Accident Prediction Models and Crash Modification Factors, highlighting effectiveness of road safety infrastructure measures worldwide, for use by road safety decision makers and practitioners worldwide. 

This Repository has been developed within the framework of the project PRACT, (Predicting Road ACcidents-a Transferable methodology across Europe) carried out by the University of Florence, the National Technical University of Athens, the Technical University of Berlin and the Imperial College London, commissioned by theConference of European Directors of Roads.

The basic assumption on which the PRACT Repository is built is that Accident Prediction Models (APM) and Crash Modification Factors (CMF) can be transferred to conditions different from the ones for which they have been developed, if selected based on scientifically valid criteria and adapted to local conditions based on historical crash data.

Sensor-Based Multi-Dimensional Approaches for Extracting Power-Two-Wheeler Driving Patterns in Various Road Environments and Lighting Conditions – 2016

A paper titled ‘Sensor-Based Multi-Dimensional Approaches for Extracting Power-Two-Wheeler Driving Patterns in Various Road Environments and Lighting Conditions’ authored by Eleni Vlahogianni, George Yannis and John Golias is now published in Advances in Transportation Studies. Data from a naturalistic Powered Two Wheelers (PTW) driving experiment are exploited using principalcomponent analysis to identify the critical PTW driving characteristics and their combinations with the finalaim to reveal useful insights on the PTW driving patterns emerging on the road. Data are collected indifferent road environments, ranging from urban road arterials to suburban roads. The analyses reveal three prevailing PTW driving patterns: i. Acceleration, ii. Maneuvering, and iii. Braking. These patterns areobserved in both inside and outside urban areas and regardless of the lighting conditions (daylight, dusk, andnight). Nevertheless, although acceleration and maneuvering patterns contain the same driving variables inall driving cases examined, braking is conducted in a varying manner with respect to the type of the area andthe time of day.  doi

Together for Safer Roads – Best Practices Report on Company and Fleet Road Safety 2016

In conjunction with World Day for Safety and Health at Work on April 28, Together for Safer Roads (TSR), the Coalition of global private sector companies, released the Advancing Road Safety Best Practices for Companies and Their Fleets report.

The Report outlines practices that companies can use to keep employees, partners, and contractors safe on the world’s roads, as well as minimize costs. Globally, between 25 and 33 percent of road crashes are work-related and 36 percent of occupational deaths are due to crashes. While these are sobering and devastating human costs, there are also great financial costs. Worldwide, employers incur costs of USD $518 billion per year due to road traffic collisions. pdf5

ETSC – Serious Injuries Strategy for the EU Roads – 2016

ETSC has just released a position paper titled: ‘A Proposal for a strategy to reduce the number of people seriously injured on EU roads‘. ETSC recommends to the EU to adopt a target of a 35% reduction between 2014 and 2020 in the number of people seriously injured. A 35% reduction over the period 2014-2020 would be similarly challenging for Member States to the target to halve road deaths between 2010 and 2020. In addition, the EU should adopt a joint strategy including measures against which delivery can be made accountable.

Towards an integrated approach of pedestrian behaviour and exposure – 2015

A paper titled ‘Towards an integrated approach of pedestrian behaviour and exposure’ authored by Eleonora Papadimitriou is now published in Accident Analysis & Prevention. An integrated methodology for the analysis of pedestrian behaviour and exposure is proposed. The paper builds on existing research on pedestrian exposure, namely the Routledge microscopic indicator, and uses integrated choice and latent variables (ICLV) models of pedestrian behaviour, taking into account road, traffic and human factors. The method is tested with data from a field survey in Athens, Greece, which used pedestrian behaviour observations as well as a questionnaire on human factors of pedestrian behaviour. The results suggest that both pedestrian behaviour and exposure are largely defined by a small number of factors: road type, traffic volume and pedestrian risk-taking. The probability for risk-taking behaviour and the related exposure decrease in less demanding road and traffic environments. A synthesis of the results reveals conditions of increased risk exposure: principal urban arterials (where risk-taking behaviour is low but the related exposure is very high) and minor arterials (where risk-taking behaviour is more frequent, and the related exposure is still high). A “paradox” of increased risk-taking behaviour of pedestrians with low exposure is found, suggesting that these pedestrians may compensate in moderate traffic conditions due to their increased walking speed. doi

Relating traffic fatalities to GDP in Europe on the long term – 2016

A paper titled ‘Relating traffic fatalities to GDP in Europe on the long term‘ with emphassis to turbulent financial situations, co-authored by Costas AntoniouGeorge Yannis, Eleonora Papadimitriou and Sylvain Lassarre is now published in Accident Analysis & Prevention. For this analysis, time series of the number of fatalities and GDP in 30 European countries for a period of 38 years (1975–2012) were exploited. This process relies on estimating long-term models (as captured by long term time-series models, which model each country separately). Based on these developments, utilizing state-of-the-art modelling and analysis techniques such as the Common Correlated Effects Mean Group estimator (Pesaran), the long-term elasticity mean value equals 0.63, and is significantly different from zero for 10 countries only. When we take away the countries, where the number of fatalities is stationary, the average elasticity takes a higher value of nearly 1. This shows the strong sensitivity of the estimate of the average elasticity over a panel of European countries and underlines the necessity to be aware of the underlying nature of the time series, to get a suitable regression model.  doi

ETSC – How safe are new cars sold in the EU? – 2016

The European Transport Safety Council (ETSC) has just published the 30th PIN Flash Report ‘How safe are new cars sold in the EU?‘. In the last decade the long term road safety trend has been positive across the EU countries, and although the reduction in deaths may be a result of many factors, including better enforcement, changing behaviour and safer infrastructure, there is little doubt thatimproved vehicle safety standards since the late 1990’s have played an important role. One important indicator of the level of vehicle safety in Europe overall is what proportion of the number of tested vehicles actually sold meet Euro NCAP’s highest safety ratings. The last assessment of the progress of the Euro NCAP programme carried out by ETSC in 2009 found that there were very significant differences between the average Euro NCAP rating of new cars sold in Eastern and Central European countries, compared to their Western European counterparts.

PIARC Improving safety in road tunnels through real-time communication 2016

The World Road Association (PIARC) has recently released a Report titled ‘Improving safety in road tunnels through real-time communication with users‘. This report is a continuation of the one published by PIARC in 2008 on ‘Human Factors and road tunnel safety regarding users‘. It describes human behavioural aspects when driving, andhow to communicate information to tunnel users in normal, congested and critical situations. It details the various systems that can be activated for real-time communication with users and reviews how these devices can be used in cases of congestion, a serious incident and fire and how the activation of these systems and devices must be adapted to the changing circumstances of the event.

Which are the effects of driver distraction and brain pathologies on reaction time and accident risk? – 2016

A paper titled “Which are the effects of driver distraction and brain pathologies on reaction time and accident risk?” authored by Dimosthenis Pavlou, Panagiotis Papantoniou, Eleonora Papadimitriou, Sophia Vardaki, George Yannis, Costas Antoniou, John Golias and Sokratis G. Papageorgiou is now published in Advances in Transportation Studies an international Journal. A driving simulator experiment with 140 participants (out of which 109 were patients) was carried out by an interdisciplinary research team of neurologists, neuropsychologists and transportation engineers. The brain pathologies examined include early Alzheimer’s disease, Parkinson’s disease, and Mild Cognitive Impairment.  A statistical analysis was carried out by means of mixed generalized linear modelling and the results indicated significant differences between the driving performance of healthy drivers and patients. Patients with cerebral diseases reacted significantly slower at unexpected incidents than the healthy ones and were more likely to be involved in an accident. The mobile phone use had a significant negative effect on both reaction time and accident probability. doi
