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

Correlation of road safety performance with social and economic indicators in the European Union 2016

A Diploma Thesis titled ‘Correlation of road safety performance with social and economic indicators in the European Union’ was presented by Ioannis Zantiris in November 2016. For this correlation a database was developed containing the most recent data regarding population, road fatalities, gross domestic product per capita, human development index, unemployment rate and several other economic and social indicators for the twenty eight countries of the European Union. Subsequently, multiple linear regression models were developed and applied for all countries and for groups of countries (northwestern, eastern, southern). The analysis demonstrated that the Human Development Index has the most important impact than any other parameter and its increase leads to road fatalities decrease.  pdf5 ppt5

ICTCT – 29th workshop, Lund, 2016

The 29th ICTCT workshop took place in Lund, Sweden, on 20-21st October 2016 and offered a multidisciplinary forum for lively discussion among inter­national experts in an open-minded and friendly atmosphere. The workshop mainly dealt with the question how to assess traffic safety. According to the philosophy of ICTCT, the safety assessment should not only rely on accident data but actively utilise other non-accident indicators that reflect the accident risk. Such methods are widely used in in rail and air transport, while acceptance is still low among road safety professionals. 

The programme is available here: pdf5

ITF – Safe System for Zero Road Deaths and Serious Injuries, 2016

The International Transport Forum has recently published an evidenced based Research Report titled “Zero Road Deaths and Serious Injuries: Leading a Paradigm Shift to a Safe System“, prepared by the Safe System Implementation Working Group composed by international road safety experts including NTUA Prof. George Yannis. This ITF Safe System Report was presented at a dedicated Road Safety Seminar, held with great success on 3 October 2016 in Paris France. All presentations are now available.  link

This Report is relying on experiences in ITF/OECD countries, with practical policy recommendations for the attention of policy makers on the various steps in implementing a safe system approach. A Safe System is based on the premise that road crashes are both predictable and preventable, and that it is possible to move towards zero road deaths and serious injuries. This, however, requires a fundamental rethink of the governance and implementation of road safety policy. link

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

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.

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

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.

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

A paper titled ‘Introducing human factors in pedestrian crossing behaviour models‘ co-authored by Eleonora Papadimitriou, Sylvain Lassarre and George Yannis is now published in the Transportation Research Part F: Traffic Psychology and Behaviour. A field survey was carried out, in which a panel of 75 pedestrians were asked to take 8 short walking trips (each one corresponding to a different walking and crossing scenario) in the Athens city centre in Greece, allowing to record their crossing behaviour in different road and traffic conditions. The same individuals were asked to fill in a questionnaire on their travel motivations, their mobility characteristics, their risk perceptions and preferences with respect to walking and road crossing, their opinion on drivers, etc. The walking and crossing scenarios’ data were used to develop mixed sequential logit models of pedestrian behaviour on the basis of road and traffic characteristics. The modelling results showed that pedestrian crossing choices are significantly affected by road type, traffic flow and traffic control. The questionnaire data were used to estimate human factors (components) of pedestrian crossing behaviour by means of principal component analysis. The results showed that three components of pedestrian crossing behaviour emerge, namely a “risk-taking and optimisation” component reflecting the tendency to cross at mid-block in order to save time, etc., a “conservative” component, concerning individuals with increased perceived risk of mid-block crossing, who also appear to be frequent public transport users, and a “pedestrian for pleasure” component, bringing together frequent pedestrians, walking for health or pleasure, etc. The introduction of these components as explanatory variables into the choice models resulted in improvement of the modelling results, indicating that human factors have additional explanatory power over road and traffic factors of pedestrian behaviour.  doi

Investigation of driver’s behaviour using vehicle diagnostics 2015

A Diploma Thesis titled ‘Investigation of driver’s behaviour using vehicle diagnostics‘ was presented by Eustratios Saplaouras in November 2015, with the support and data from OSeven Telematics. The aim of this Diploma Thesis is to investigate the driver’s behavior through the on-board diagnostics of the vehicle. A large data set was exploited, which were recorded per second and concerned the exact position of the vehicle, its speed, the spots where the driver was performing a sudden change of speed or a sudden maneuver, the fuel consumption, etc. Mathematical statistical models were developed using linear and binary logistic regression. The results demonstrated a strong correlation between over-speeding and driver harsh behavior, although the two dimensions are disproportionate, as well as the occurrence of higher driving speeds during risky hours (00:00-04:00). pdf5 ppt5

European Commission – Good practices for road user distraction risk 2015

The Road Safety Unit of DG Move of the European Commission has recently released a Report titled ‘Study on good practices for reducing road safety risks caused by road user distractions’ prepared by TRL, TNO and RAPPTrans. The study concluded that 10-30% of road accidents in the EU could have distraction as a contributory factor, although limitations of both data and their definitions mean that this figure requires further validation.

The Study identified a series of countermeasures that can be used to address driver distraction, including non-technology-based approaches

[legislation, certification, public awareness campaigns and education during the licensing acquisition process (as well as for professional drivers)] and the most promising technologies[collision warning systems (forward collision warning and lane departure warning), voice recognition, biometry, head up displays, artificial intelligence, and vehicle automation]. Standardised Human-Machine Interface design should also be an important component of an EU-wide approach to distraction. The Study concluded with nine key cost beneficial recommendations related to data, technologies, awareness & education, and standards addressed to the European Commission but also to all national and international road safety stakeholders (Authorities, Industry, Research, Interest groups). pdf5

Together for Safer Roads Global Coalition – White Paper 2015

The Private Sector Global Coalition Together for Safer Roads (TSR) composed by 11 leading global companies has recently published a White Paper titled “Investing in Road Safety – A global imperative for the private sector“, setting the orientations and priorities of the TSR Coalition for advancing road safety in the world. This White Paper was prepared by the TSR’s Expert Panel composed by international road safety experts, with the active participation of NTUA Prof. George Yannis.

In this White Paper, TSR’s Expert Panel assesses progress since the United Nations General Assembly established theUnited Nations Decade of Action for Road Safety in 2010,identifies gaps, and discusses the role of the private sector in advancing road safety. The role of the Global private sector Coalition is seen under three perspectives: as collaborators with the public sector and NGOs in demonstration projects; as managers of vehicle fleets traversing the world’s roads; and as participants in specific industries that have unique opportunities to improve road safety. With the United Nations Decade of Action for Road Safety at its midpoint, business has an opportunity to drive a groundswell of meaningful cross-sector action and help save millions of lives.

Akis Theofilatos defended his PhD thesis on accident probability and severity 2015

Athanasios Theofilatos has successfully defended his PhD thesis titled: An advanced multi-faceted statistical analysis of accident probability and severity exploiting high resolution traffic and weather data. This PhD thesis was carried out at the Department of Transportation Planning and Engineering at the School of Civil Engineering of the National Technical University of Athens under the supervision of Prof. George Yannis.

The objective of this PhD thesis is the investigation of accident probability and severity exploiting high resolution traffic and weather data from urban roads and motorways, collected on a real-time basis, with specific focus on Powered-Two-Wheelers. For that purpose, an advanced mesoscopic multi-faceted statistical analysis was conducted in order to expand previous road safety work and contribute to the further understanding of the complexity of accident probability and severity. Linear and non-linear models were developed on the basis of 6-year accident data from urban roads as well as an urban motorway in Greater Athens area (Attica Tollway). Empirical findings indicate that high resolution traffic and weather data are capable of opening new dimensions in accident analysis in urban roads and urban motorways. The multi-faceted statistical analysis conducted in the thesis has revealed a consistent and strong impact of traffic parameters on accident probability and severity. It is interesting that weather parameters were not found to influence accident probability and severity when linear relationships are considered, however, the application of cusp catastrophe models demonstrated that it is likely that even small traffic and weather changes may have a critical impact on road safety in urban roads as sudden transitions from safe to unsafe conditions (and vice versa) may occur, especially for PTW traffic. pdf5 ppt5

PIARC – Road Safety Manual 2015

The World Road Association (PIARC) has recently published the long waited second edition of the Road Safety Manual. The PIARC Road Safety Manual is aligned with key pillars of the United Nations Decade of Action for Road Safety 2011-2020 (1: Road Safety Management, 2: Safer Roads and Mobility and 4: Safer Road Users) and isdesigned to assist countries at every stage of infrastructure development and to fulfill road safety objectives. This comprehensive resource builds on the broad range of knowledge and experience provided by PIARC in the first edition. It includes new thinking on road safety and offers a clear argument on why adopting a Safe System approach is crucial for each country. The Safe System approach aims for a more forgiving road system that takes human fallibility and vulnerability into account. Under the Safe System approach, everyone (public agencies, automobile manufacturers, road users, enforcement officials, and others) must share the responsibility for road safety outcomes.

ERF Position Paper – Traffic Signs in European Roads 2015

The European Road Federation (ERF) launched recently its Position Paper towards improving Traffic Signs in European Roads: “Improved Signage for better Roads“. This Position Paper advocates for authorities to avoid or tackle the over-proliferation of traffic signs and to ensure that those installed display a clear message, in order to achieve better road safety and traffic flow, and good use of public resources. Road authorities need to set a multiannual maintenance action plan. The need to adapt to the needs of an ageing driver population, by introducing a minimum maintenance standards for safety critical signs under the Vienna Convention is highlighted. This position paper calls for all stakeholders involved to examine the benefits of greater harmonisation of signs within the Vienna Convention to maximise the safety benefits of new vehicle technologies as well as to provide for a more familiar environment for increasing cross-border traffic volumes. pdf5

IRTAD – Why Does Road Safety Improve When Economic Times Are Hard? 2015

The International Road Traffic and Accident Database Group (IRTAD) of the International Transport Forum (ITF/OECD) published a Report on Why Does Road Safety Improve When Economic Times Are Hard?. In this Report previous studies were reviewed and new ones are presented demonstrating that there is clear evidence that when economic growth declines, and particularly when unemployment increases, road safety improves, particularly among young people.

Furthermore it was found that the economic downturn in 2009-10 may well have contributed to about two-thirds of the decrease in road fatalities since 2008. It is suggested that policy makers need to take careful account of these results when setting up road safety targets and when designing road safety strategies for the future. NTUA has contributed actively to the preparation of this Report.

Assessment of Driving Simulator Studies on Driver Distraction – 2015

A paper titled ‘Assessment of Driving Simulator Studies on Driver Distraction‘ co-authored by Panagiotis Papantoniou, Eleonora Papadimitriou and George Yannis is now published in Advances in Transportation Studies Journal. The objective of this research is the critical assessment of driving simulator studies on driver distraction. For this purpose 45 scientific papers have been examined with respect to the design of driving simulator experiments on the effects of various sources of driver distraction (in-vehicle or external). Through this analysis it appears that the most common distraction sources examined are visual distraction and cell phone use, while other sources of distraction have received notably less attention in existing studies. The simulated road environment of most experiments was rural, whereas far less is known on the effects of distraction in urban areas; furthermore, ambient traffic is not explicitly simulated and the effect of traffic flow on distracted driving may be a key question for further investigation. Finally, driver distraction is expressed by a number of measurements, in terms of its impact to driver attention (hands-off the wheel, eyes-off the road), driver behaviour (vehicle speed, headway, lateral position, driver reaction time) and driver accident risk. Although these different measurements describe different aspects of the distracted driving mechanism, it would be important to focus on the most sensitive ones, keeping in mind the entire chain of distracted driving causes and impacts, in order to significantly enhance the potential of exploitation of the results of existing studies. pdf5

Exploring the association between working memory and driving performance in Parkinson’s disease 2015

A paper titled ‘Exploring the association between working memory and driving performance in Parkinson’s disease‘ co-authored by Sofia Vardaki, Hannes Devos, Ion BeratisGeorge Yannis and Sokratis Papageorgiou is now published in Traffic Injury Prevention. The aim of this study was toexplore whether varying levels of operational and tactical driving task demand differentially affect drivers with Parkinson’s disease (PD) and control drivers in their sign recall. Drivers of the control group performed better than drivers with PD in a sign recall task, but this trend was not statistically significant (p = 0.43). Also, regardless of group membership, subjects’ performance differed according to varying levels of task demand. Performance in the sign recall task was more likely to drop with increasing task demand (p = 0.03).This difference was significant when the variation in task demand was associated with a cognitive task, i.e., when drivers were required to apply the instructions from working memory. Although the conclusions drawn from this study are tentative, the evidence presented here is encouraging with regard to the use of a driving simulator to examine isolated cognitive functions underlying driving performance in PD. With an understanding of its limitations, such driving simulation in combination with functional assessment batteries measuring physical, visual and cognitive abilities could comprise one component of a multi-tiered system to evaluate medical fitness to drive.  doi

Impact of roadside advertising to driver behaviour and safety in cities 2015

A Diploma Thesis titled ‘Investigation of the impact of roadside advertising  to driver behaviour and safety in cities with the use of driving simulator‘ was presented by Anastasia Gkouskou in July 2015. An experimental process on a driving simulator was carried out, in which all participants drove in specially selected driving scenarios. Regression statistical models were developed to investigate the impact of roadside advertising on the mean speed and the lateral position of the vehicle from the right borderline (lognormal) and on the mean reaction time (linear). The models’ application demonstrated thatroadside advertising leads to small increase of the mean reaction time and the mean lateral position of the vehicle from the right borderline. At the same time, it leads to small decrease of the mean speed, perhaps due to overloaded driving environment. Finally, roadside advertising appears to have no effect on the headway distance and the probability of getting involved in an accident. pdf5 ppt5

Assessing Selected Cognitive Impairments Using a Driving Simulator: A Focused Review – 2015

A paper titled ‘Assessing Selected Cognitive Impairments Using a Driving Simulator: A Focused Review‘ co-authored by Vardaki Sophia, George Yannis and Sokratis Papageorgiou is now published in Advances in Transportation Studies. The paper offers a focused review of studies investigating driving performance as assessed on simulators, targeting cognitive impairments which are age-related or caused by neuro-degenerative disorders, including mild cognitive impairment (MCI), Alzheimer’s disease (AD), Parkinson’s disease (PD) and stroke. The paper references selected findings highlighting what they reveal about several key methodological issues: gauging task demands in relation to actual driving; how differences in cognitive ability affect performance, and how this varies for different driving tasks; issues related to scenario design, such as simulator limitations, scenario authoring and simulated driving tasks; the need to develop operational definitions and comparability; limitations that affect the generalizability of simulator studies; the simulator adaptation syndrome; the bias in performance assessment that can result when drivers have not adequately adapted to the simulator; and driving simulator validation. The issues covered would help readers recognize the many confounding variables and sources of measurement error that can flaw research of this type, and their implications for future investigations.  doi

Good Practices on Cost-Effective Road Infrastructure Safety Investments – 2016

A paper titled ‘Good Practices on Cost – Effective Road Infrastructure Safety Investments‘ co-authored by Eleonora Papadimitriou, George Yannis and Petros Evgenikos is published in the International Journal of Injury Control and Safety Promotion. The paper presents the findings of research aiming to quantify and subsequently classify several infrastructure-related road safety measures, based on the international experience attained through extensive and selected literature review and additionally on a full consultation process including questionnaire surveys addressed to experts and relevant workshops. The results suggest that the overall cost effectiveness of a road safety infrastructure investment is not always in direct correlation with the safety effect and is recommended that cost-benefit ratios and safety effects are always examined in conjunction with each other in order to identify the optimum solution for a specific road safety problem in specific conditions and with specific objectives.  doi

ETSC – Europe must boost safety for cyclists and walkers 2015

The European Transport Safety Council (ETSC) has just published the PIN Flash Report ‘Making walking and cycling on Europe’s Roads Safer‘, with the contribution of NTUA.Around 138,400 pedestrians and cyclists lost their lives on EU roads between 2001 and 2013. Deaths of unprotected road users have been decreasing at a slower rate than those of vehicle occupants. In the last ten years deaths among pedestrians decreased by 41%, those among cyclists by 37% and those among power two wheeler (PTW) users by 34% compared to a 53% decrease for vehicle occupants. Since 2010 the reduction in the number of pedestrian and cyclist deaths has slowed down markedly. The safety of unprotected road users should therefore receive special attention from policymakers at the national and European levels.

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.

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

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
