A systematic cost-benefit analysis of 29 road safety measures, 2019

A paper titled “A systematic cost-benefit analysis of 29 road safety measures” authored by Stijn Daniels, Heike Martensen, Annelies Schoeters, Wouter Van den Berghe, Eleonora Papadimitriou, Apostolos Ziakopoulos, Susanne Kaiser, Eva Aigner-Breuss, Aggelos Soteropoulos, Wim Wijnen, Wendy Weijermars, Laurent Carnis, Rune Elvik, Oscar Martin Perez is now published in Accident Analysis and Prevention. For the purposes of this study the authors collected and (re-)analyzed evidence in order to conduct cost-benefit analyses (CBAs) for 29 road safety measures. The information on crash costs was based on data from a survey in European countries.  A systematic procedure was applied including corrections for inflation and Purchasing Power Parity in order to express all the monetary information in the same units (EUR, 2015). Cost-benefit analyses were carried out for measures with favourable estimated effects on road safety and for which relevant information on costs could be found. Results were assessed in terms of benefit-to-cost ratios and net present value and are included also at the SafetyCube DSS. doi

European Commission – Slow improvements in road fatalities in the European Union, 2019

According to the European Commission preliminary statistics, fewer people died on European roads in 2018 but more efforts are needed to make a big leap forward. In 2018, there were around 25.100 fatalities in road accidents in the EU 28. This is a decrease of 21% compared to 2010, and 1% compared to 2017. The EU countries with the best road safety results in 2018 were the United Kingdom (28 deaths/million inhabitants), Denmark (30/million), Ireland (31/million), and Sweden (32/million), whereas the best improvement since 2010 was demonstrated by Greece (-45%) and Lithuania (-43%). With an average of 49 road deaths per one million inhabitants, this confirms that European roads are by far the safest in the world, but it also shows that we are off track to reach our target of halving the number of road deaths by 2020

Combined impact of road and traffic characteristics on driver behavior using data from smartphones, 2019

A Diploma Thesis titled “Combined impact of road and traffic characteristics on driver behavior using data from smartphones” was recently presented by Virginia Petraki. High resolution driving behavior data were collected using sensors of smartphones which were combined with traffic and road geometry characteristics and subsequently were depicted spatially using GIS. From the application of these models it is observed that in road segments there is an increase in the number of harsh events if average traffic volume per lane increases in the respective segments. Furthermore, in junctions as the average occupancy increases, there is an increase in harsh accelerations, and as average speed increases more harsh decelerations occurpdf5 ppt5

Road safety behavior of drivers with neurological diseases affecting cognitive functions: an interdisciplinary Structural Equation Model analysis approach, 2018

A paper titled “Road safety behavior of drivers with neurological diseases affecting cognitive functions: an interdisciplinary Structural Equation Model analysis approach” authored by Dimosthenis Pavlou and George Yannis is now published in Advances in Transportation Studies. This research suggests the evaluation of driving behavior by using multiple driving indexes in a combined integrated manner, through a large-scale driving simulator experiment, comprising medical/neurological and neuropsychological assessments of 225 active drivers, and a set of driving tasks for different traffic volumes, different driving environments, including in-vehicle distraction conditions. The statistical analysis methodology developed and implemented was based on Principal Component Analysis and Structural Equation Models (SEMs). SEM results indicated that the impact of neurological diseases affecting cognitive functions is significantly detrimental on the latent variables “driving performance” and on the observed variables “reaction time” and “accident probability”. The AD group had the worse driving behavior profile among the examined groups with neurological diseases affecting cognitive functions. doi

ETSC – EU Strategy for Automated Mobility, 2018

The European Transport Safety Council (ETSC) has published a briefing synthesis titled “EU Strategy for Automated Mobility”. ETSC warmly welcomes and fully agree with the Commission’s acknowledgement that when it comes to automated mobility, “only the highest safety and security standards will suffice”. This must remain the guiding principle in the years to come. Automated driving has the potential to significantly improve road safety. However, recent collisions involving vehicles with automated technology on board demonstrate that automated driving may also pose new risks to road safety, and that the technology is not yet mature.  pdf5

WHO – Global Status Report on Road Safety highlights insufficient progress, 2018

The Global Status Report on Road safety 2018 has been published by World Health Organisation (WHO) with the active contribution of NTUA, in December 2018, highlighting insufficient progress as the number of annual road traffic deaths has reached 1.35 million. Road traffic injuries are now the leading killer of people aged 5-29 years. The report suggests that the price paid for mobility is too high, especially because proven measures exist. These include strategies to address speed and drinking and driving, among other behaviours; safer infrastructure like dedicated lanes for cyclists and motorcyclists; improved vehicle standards such as those that mandate electronic stability control; and enhanced post-crash care. Drastic action is needed to put these measures in place to meet any future global target that might be set and save lives.  pdf5

Identification of patterns of driver speeding behaviour and safety margins from tangent to curve, 2018

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

Which factors affect accident probability at unexpected incidents? A structural equation model approach, 2018

A paper titled “Which factors affect accident probability at unexpected incidents? A structural equation model approach” authored by Panagiotis Papantoniou, Constantinos Antoniou, George Yannis and Dimosthenis Pavlou is now published in Journal of Transportation Safety & Security. A driving simulator experiment was carried out, in which 95 participants were asked to drive under different types of distraction (no distraction, conversation with passenger, cell phone use) in different road and traffic conditions. Then, in the framework of the statistical analysis, driving performance is estimated as a new unobserved (latent) variable based on several individual driving simulator parameters while a structural equation model is developed investigating which factors lead to increased accident probability at unexpected incidents. Regarding driver distraction, results indicate that cell phone use has a negative effect on accident risk confirming the initial hypothesis that when talking on the cell phone drivers find it difficult to handle an unexpected incident and as a result are more likely to commit an accident. doi

Dimitris Tselentis defended his PhD Thesis on Benchmarking Driving Efficiency using Data Science Techniques, 2018

Dimitris Tselentis has successfully defended his PhD dissertation titled: Benchmarking Driving Efficiency using Data Science Techniques applied on Large-Scale Smartphone 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, with the support and data from OSeven Telematics. The main objective of this PhD is to provide a methodological approach for driving safety efficiency benchmarking on a trip and driver basis using data science techniques. It also investigates the way to achieve this by defining a safety efficiency index based on travel and driving behaviour metrics collected from smartphone devices. Furthermore, the present doctoral research proposes a methodological framework for identifying the least efficient trips in a database and for estimating the efficient level of metrics that each non-efficient trip should reach to become efficient. Finally, this dissertation’s objective is to study the temporal evolution of driving efficiency and identify the main driving patterns and profiles of the driver groups formed. pdf5 ppt5

The effect of anger on driver behavior and safety, 2018

A Diploma Thesis titled “The effect of anger on driver behavior and safety” was presented by Orestis Gavalas in July 2018. In order to achieve this goal, a driving simulator experiment was conducted and a questionnaire including the DAX scale was filled in a sample of 125 drivers. The collected data were grouped into anger components using the factor analysis method. Subsequently, both linear and logarithmic regression models were developed. Valuable conclusions were reached including men demonstrating higher levels of driving anger as well as that anger decreases with increasing age. The presence of anger is related to the increase in average speed, the reduction of headway (measured in time) and the increase in the probability of being involved in an accident and a road traffic infringement. On the other hand, forgiveness and noble mindedness lead to fundamentally opposite effects. pdf5 ppt5

Mobility and Road Safety in European cities, 2018

A Diploma Thesis titled “Mobility and Road Safety in European cities” was recently presented by Dimitrios Giagkou, focusing on the impact of mobility characteristics on road safety in European cities. For this analysis, various international databases (CARE, UITP, Eurostat) were exploited with data on road accident fatalities, demographics and mobility characteristics of 25 European cities in 2012. Generalized Linear Models were developed for both the total number of fatalities and for specific subcategories too. The results led to the conclusion that more public transport capacity offered, more cycle trips and fewer motorcycles lead to a reduction in the number of fatalities in urban road accidents. Moreover, it was found that denser road network, higher population density and higher GDP per capita are correlated with fewer fatalities in urban road accidents. pdf5 ppt5

Impact of economic, social and transport indicators on road safety during the crisis period in Europe, 2018

A Diploma Thesis titled “Impact of economic, social and transport indicators on road safety during the crisis period in Europe” was presented by Dimitrios Nikolaou in July 2018. For this analysis a database containing Human Development Index (HDI), suicides, passenger-kilometers and road fatalities for European states for 2006-2015 was developed. The results led to the conclusion that Human Development Index has the most important impact and its increase leads to road fatalities decrease. Moreover, the economy evolution effect on road accidents is more important than social and transport indicators. Especially after the economic crisis, the impact of the economy is even higher. Passenger-kilometers were also found with increased impact on the number of road fatalities after the economic crisis. pdf5 ppt5

How many crashes are caused by driver interaction with passengers? A meta-analysis approach, 2018

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

ITF – Cooperative Mobility Systems and Automated Driving, 2018

The International Road Traffic and Accident Group (IRTAD) of the International Transport Forum (ITF/OECD) published recently a new Report: “Cooperative Mobility Systems and Automated Driving”. Automated vehicles could make roads safer as well as reduce congestion. Whether society will be able to capture these benefits while minimizing negative impacts depends on effective regulation of self-driving vehicles. The technology is still largely experimental and mass use is likely to take decades. This report reviews the range of existing service concepts for automated driving systems and technologies, the operational environments they require and assesses the need for regulatory action pdf5

ITF – Integrating Urban Public Transport Systems and Cycling, 2018

The International Transport Forum (ITF/OECD) published recently a new Report: “Integrating Urban Public Transport Systems and Cycling”. Seamless integration between bus, BRT, light rail, metro and rail systems and walking and cycling is the main challenge in delivering competitive levels of service, in terms of convenience, flexibility, cost as well as safety. ITF Report recommendations suggest that cycling can greatly extend the range of public transport options available to urban travellers. Cycling significantly increases the catchment area of rail stations with bike-share systems greatly facilitating the use of cycling to complete trips on public transport as well as promoting cycling more generally.  pdf5

Structural equation model analysis for the evaluation of overall driving performance: A driving simulator study focusing on driver distraction, 2018

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