Critical factors for the identification of traffic safety events in urban areas, October 2020

An NTUA Diploma Thesis titled “Critical factors for the identification of traffic safety events in urban areas” was recently presented by Foteini Bardi. According to the results, the random forest model proved to produce more reliable results predicting traffic safety events with a lower false alarm rate, when compared to binomial logistic regression. Moreover, factor analysis demonstrated that data representing one minute before the event can be described by speed, the deviation of the vehicle from the middle of the road and the distance from the right boundary line.  Similarly, data during the event can be better described through speed and longitudinal and lateral acceleration.  pdf5 ppt5

Analysis of pedestrians distracted behaviour talking on mobile phone, 2019

A Diploma Thesis titled “Analysis of pedestrians distracted behaviour talking on mobile phone” was recently presented by Dimitra Typa. The aim of this Diploma Thesis was to investigate the impact of hand-held cell phone conversation on pedestrians’ traffic and safety behaviour, when crossing signalized intersections. An outdoor-environment experiment, through video recording, was conducted in real road conditions, in three signalized intersections at the centre of Athens for the purpose of comparing the behaviour of distracted and non-distracted pedestrians. The results of the models’ application demonstrated that distraction caused by hand-held cell phone conversation had a negative impact on pedestrians’ main traffic and safety characteristics, since, in general, mobile use not only decreases pedestrians’ speed but also increases their probability of being involved in an accident with an oncoming vehicle. pdf5 ppt5

Driving Safety Efficiency Benchmarking Using Smartphone Data, 2019

A paper titled “Driving Safety Efficiency Benchmarking Using Smartphone Data” authored by Dimitrios Tselentis, Eleni Vlahogianni, and George Yannis is now published in Transportation Research Part C: Emerging Technologies. This paper aims to provide a methodological framework for the comparative evaluation of driving safety efficiency based on Data Envelopment Analysis (DEA). The analysis considers each driver as a Decision-Making Unit (DMU) and aims to provide a relative safety efficiency measure to compare different drivers based on their driving performance. The proposed methodological framework is tested on data from fifty-six (56) drivers during a 7-months period. Findings help distinguish the most efficient drivers from those that are less efficient. Most common inefficient driving practices are identified (aggressive, risky driving, etc.) and driving behaviour is comparatively evaluated and analyzed. doi

ITF – Road Safety in European Cities Report, 2019

The International Transport Forum (ITF/OECD) published recently a new Report: “Road Safety in European Cities – Performance Indicators and Governance Solutions”. This reports benchmarks road safety performance for 72 urban areas, mostly in Europe, and illustrates governance solutions to improve urban road safety with case studies conducted in Lisbon (Portugal) and Riga (Latvia). The report proposes new road safety indicators to assess the level of risk for each mode of transport. It finds that a modal shift away from private motor vehicles could significantly enhance road safety in dense urban areas and deliver public health benefits associated with increased physical activity and improved air quality.  pdf5

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

The European road safety decision support system on risks and measures, 2019

A paper titled “The European road safety decision support system on risks and measures” authored by the Horizons 2020 SafetyCube project team is now published in Accident Analysis and Prevention. The European Road Safety Decision Support System is an innovative system providing the available evidence on a broad range of road risks and possible countermeasures. This paper describes the scientific basis of the DSS. The structure underlying the DSS consists of (1) a taxonomy identifying risk factors and measures and linking them to each other, (2) a repository of studies, and (3) synopses summarizing the effects estimated in the literature for each risk factor and measure, and (4) an economic efficiency evaluation instrument (E3-calculator). doi

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

Correlation of driver behaviour and fuel consumption using data from smartphones, 2019

A Diploma Thesis titled “Correlation of driver behaviour and fuel consumption using data from smartphones” was recently presented by Eva Michelaraki. The aim of this Diploma Thesis is the correlation of driver behaviour and fuel consumption using data from smartphones. To achieve this objective, data collected from 17 drivers who participated at a naturalistic driving experiment for four months are analyzed. The results demonstrated that there was a remarkable reduction in fuel consumption, by improving the way participants were driving and also a smoother and a greener driver behavior was achieved. A stronger correlation has emerged between harsh accelerations and fuel consumption, but also speed, braking, smartphone usage while driving, driving at night and demographic features had a direct impact on fuel consumptionpdf5 ppt5
