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. 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 International Transport Forum (ITF/OECD) published recently a new Report: “Safer City Streets: Global Benchmarking for Urban Road Safety”, with the active contribution of NTUA. This document aims to support cities in setting road safety targets and to monitor progress in improving urban road safety. Pedestrians, cyclists and motorcyclists account for nearly 80% of urban traffic fatalities. Cities should thus intensify efforts to improve the safety of vulnerable road users. This document presents traffic safety indicators for different road user groups collected in 31 cities worldwide to facilitate the evaluation, monitoring and benchmarking of road safety outcomes. It places a particular attention on measuring the risk of fatality per unit distance traveled.  LINK.png pdf5

The European Commission’s Directorate General for Mobility and Transport (DG Move) published the Final Report of the “Study on powered two-wheeler and bicycle accidents in the EU, SaferWheels”, with the active contribution of NTUA. The SaferWheels study was conducted to investigate accident causation for traffic accidents involving powered two-wheelers and bicycles in the European Union. The objective of the study was to gather PTW and bicycle accident data from in-depth crash investigations, obtain accident causation and medical data for those crashes, and to store the information according to an appropriate and efficient protocol enabling a causation-oriented analysis. LINK.png

The European Commission’s Directorate-General for Research and Innovation published a Report titled “Analysis of the state of the art, barriers, needs and opportunities for setting up a Transport Research Cloud”, with the active contribution of NTUA Professor George Yannis. This Report focuses on the requirements for data sharing within the transport research community. In particular, the Report examines the potential of a Transport Research Cloud (TRC) as a subset of the European Union’s European Open Science Cloud (EOSC) initiative. Six domain experts collected data based on their personal experiences, contacts, prior research and a survey sent out to other researchers in the transport domain to enable a preliminary analysis concerning the needs, barriers and potential benefits for the domain should a TRC be realized. Road Safety constitutes a major component of this Transport Research Cloud.  LINK.png

1968_Convention_Anniversary_web-150x150.jpg

UNECE celebrates the 50th anniversary of Vienna Conventions on Road Traffic and on Road Signs and Signals, 1968-2018. At the turn of their 50th anniversary, the Vienna Conventions on Road Traffic and on Road Signs and Signals from 1968 are more relevant than ever. Whether helping to address the most critical road safety needs, or facilitating the development of automated driving functionalities, reference to these legal texts, which are evolving with technological developments, is a necessity for countries around the world. The two Conventions have a global scope and are important frameworks facilitating international road traffic through uniform traffic rules and harmonized road signs, signals, symbols and markingsLINK.png video

On the occasion of the World Day of Remembrance for Road Traffic Victims, the European Commission presented the final Road Safety Figures for 2017, which show for the second year in a row a decrease by 2% of road fatalities in the EU compared to the previous year. European Coordinator for Road Safety Matthew Baldwin said: “Whilst European roads are the safest in the world, the downward curve has flattened out in past years. We still have many challenges ahead of us: I especially think of vulnerable road users, who– as the figures show- are making up a larger share of the casualties, especially in urban areas. We need an active, cooperative, holistic approach amongst all stakeholders to implement what we know needs to be done – the Safe System“. LINK.png pdf5

UNECE and the Ministry of Economy and Sustainable Development of Georgia organised a Workshop titled: “National Road Safety Policy development – trends and challenges| which was held with great success in Tbilisi, Georgia on 13-14 November 2018. The aim of the workshop was to strengthen the knowledge of Central Asia, Caucasus and East-Europe countries on how to define national road safety policy and improve road safety situation. As such, the workshop helped participants to better understand international and regional best practices on road safety management, collection and utilization of robust and reliable road safety statistics and tools (SafeFITS, and RSPR) and methodologies for setting up road safety strategic goals. pdf5  NTUA actively contributed with the following presentations:

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

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
