In a recently published study conducted at Stanford University (USA), using a range of parameters for each scientist’s research contribution and influence, million scientists data from Scopus database were analysed. According to this study 971 Greek scientists are contained in the global top 2%, among which 130 researchers from the National Technical University of Athens (NTUA). 21 Professors from the School of Civil Engineering of NTUA are among the top 2% researchers in the world (5 within the top-ten of NTUA), while 6 of them from the Department of Transportation Planning and Engineering, (5 within the top-eleven of the School of Civil Engineering). 

The European Commission adopted a series of proposals designed to improve the experience of passengers and travellers by strengthening their rights. These proposals focuse on stronger passenger rights, protection of package travellers, better multimodal travel information services and the creation of a common European mobility data space. The new rules will also provide for safer and smoother journeys, especially those involving different travel services or transport modes, ensuring that passengers have access to direct support, and enhanced real-time information, for example on delays and cancellations. 

The World Road Association – PIARC implemented an ambitious PIARC Knowledge Exchange project, aiming at sharing knowledge about road safety, with the active contribution of NTUA, especially within Low and Middle Income Countries with limited resources but also in more developed economies with different needs and priorities. The theme of this month refers to tunnels, as presented by the chair of the PIARC Technical Committee 4.4 “Road Tunnels”  Ingo Kaundinya. Throughout the year, PIARC focuses on the Safe System approach, addressing safe roads and roadsides, safe road users, safe vehicles and safe speeds.   

An NTUA Diploma Thesis titled “Impact of compliance for the reduction of sulphur oxide emissions in the shipping industry” was recently presented by Maria Konti. In order to achieve this, two case studies based on data taken from two existing bulk carriers were presented. The study indicates that options i) and iii) are accompanied by significant capital expenditures (CapEx), while the Scrubber option is shown to be the most cost-effective considering 5 and 10-year depreciation scenarios. Other important parameters such as the vessels’ age, the management companies’ cash flow and risk appetite, and the hire rates are shown to influence the results.  

An NTUA Diploma Thesis titled “Analysis of traffic behaviour and road safety of delivery riders” was recently presented by Konstantinos Choumis.  To achieve this, a questionnaire was developed, and 200 food delivery drivers from all over Attica were asked to respond based on the stated preference method for various hypothetical scenarios involving changes in delivery time, crash risk reduction and profit loss per delivery. The results of the multinomial logistic regression model revealed that the variables influencing the food delivery drivers’ choices in hypothetical scenarios include: delivery time, crash risk reduction, profit loss, age of the driver, the number of fines received, and their opinion on stricter penalties as a measure to improve road safety.  

An NTUA Diploma Thesis titled “Survey of analysis of the acceptance of reduced speed limits on Greek motorways from 130km/h” was recently presented by Christina Agourou. In order to achieve this, a questionnaire was created to collect data using the stated preference methodology, examining three different scenarios regarding speed limits. In conclusion, the participants, depending on their individual characteristics and beliefs, agree more or less about the criticality of the role of some variables, such as cost of fuel, journey time and estimation of the number of number of people injured or killed in motorway crashes.  

An NTUA Diploma Thesis titled “Impact factors of children’s road safety in Europe” was recently presented by Alexia Georgiou. For this purpose, data from the European CARE database on the number of victims aged 0-14 in road crashes and the characteristics of these crashes were used. Linear regression models and negative binomial regression models were developed. These models led to the conclusion that the percentage of drivers who develop speeds higher than the permitted ones in residential areas and the percentage of drivers who transport children over 150cm tall without a seat belt significantly affect the number of victims aged 0-14. Regarding crash characteristics, good weather conditions are associated with an increase in the number of victims.  

An NTUA Diploma Thesis titled “Investigation of the impact of eco driving on fuel consumption using smartphone data” was recently presented by Aimilia Triantafyllou. To achieve this objective, data collected from 15 drivers who participated in a naturalistic driving experiment for a period of six months are analyzed. The results demonstrated that by improving the participants’ driving style, a remarkable reduction in fuel consumption was observed; and smoother and more ecological driver behavior was achieved.  

An NTUA Diploma Thesis titled “Investigation of eco driving benefits at the rural network using driving simulator” was recently presented by Panagiota Kourenti. To achieve this objective, driving data from 39 participants were collected and the experimental procedure was carried out using a driving simulator. To complete the collection of the necessary data, the driving characteristics of the participants were collected through a questionnaire survey. The key conclusions of this thesis are that eco-driving reduces the emission of pollutants into the atmosphere, the fuel consumption of vehicles and the probability of road crashes.  

An NTUA Diploma Thesis titled “Comparative Evaluation of Road Safety Performance of the European Union Countries” was recently presented by Panagiotis Konstantopoulos. Key Performance Indicators (KPIs) for road safety were exploited as collected in 2021-2022 within the Baseline project, together with data from Eurostat and EC CARE road crash databases. It was observed that an increase in the percentage of vehicles travelling within the speed limits on urban roads and of the percentage of seat belt use, as well as an increase in the proportion of new vehicles in the total fleet, are associated with a clear reduction in crash severity.  

An NTUA Diploma Thesis titled “Comparative analysis of road safety performance in the Regions of Greece ” was recently presented by Lydia Papagianni. For this purpose, Key Performance Indicators (KPIs) for road safety in Greece were collected and calculated for the year 2022 as part of the European Union’s Baseline project. It was found that as the KPI for the use of protective equipment, distraction from handheld devices, compliance with speed limits, the per capita GDP, and the number of hospital beds increase, the number of road fatalities per population decreases. Conversely, as the employment rate increases, the road fatalities also increase.  

The World Day of Remembrance for Road Traffic Victims is observed on the third Sunday of November each year, launched in 1995 by the European Federation of Road Traffic Victims (FEVR) and since 2005 adopted by the United Nations and is dedicated to remembering the many millions killed or injured in road crashes and their families and communities, as well as to pay tribute to the dedicated emergency crews, police and medical professionals who daily deal with the traumatic aftermath of road death and injury. A book written by Jeannot Mersch and Briggite Chaudhry has been published for celebrating 30 years for the Day of Remembrance.     

The World Road Association – PIARC implemented an ambitious PIARC Knowledge Exchange project, aiming at sharing knowledge about road safety, with the active contribution of NTUA, especially within Low and Middle Income Countries with limited resources but also in more developed economies with different needs and priorities. The theme of this month refers to infrastructure, as presented by the chair of PIARC Technical Committee 3.1 John Milton. Throughout the year, PIARC focuses on the Safe System approach, addressing safe roads and roadsides, safe road users, safe vehicles and safe speeds.   

A new book titled “La Vitesse: Enjeux contemporains et politiques publiques” authored by Laurent Carnis and Dominique Mignot, was recently published. This book guides the reader through the theme of the reflection of speed in society. Speed is at the heart of  society as it continues to structure everyday behavior, expressing a form of modernity and reflecting the relationship with time and risk. Furthermore, speed is also a matter of public policy, with road safety and public health at stake. It is the result of interactions between behavior, vehicles and infrastructure. These policies must ensure that the measures taken are acceptable and effective on the ground, but they require strong commitments from decision-makers. 

The European Commission published the latest figures on Road safety in the EU, showing that 20,640 people were killed in road crashes in 2022, a 4% increase in relation to 2021 as traffic levels recovered after the pandemic. While the underlying long-term trend is downward (-9% compared to pre-pandemic year), it is not decreasing at a fast enough pace to reach the EU target of halving the number of deaths by 2030.  Preliminary figures for the first six months of 2023 indicate the number of deaths on EU roads has fallen slightly, compared with the same period in 2022. 

Bolt micromobility operator is actively engaged to high level safety of its services and has recently published a Report introducing e-scooter safety and gaining a deeper insight into the world of safe Bolt e-scooter and e-bike rides.  Bolt is assisted by a Micromobility Safety Committee composed by renown urban safety experts, with the active contribution of NTUA, which provide advice, feedback and recommendations regarding micromobility safety performance, strategy, and future initiatives.   

The European Commission proposed a list of principles, in order to boost cycling across Europe. This proposal recognises cycling as a sustainable, accessible and inclusive, affordable and healthy means of transport, with strong added value for the EU economy. The Declaration should serve as a strategic compass for existing and future policies and initiatives related to cycling. The proposed principles will help the EU achieve its European Green Deal, Sustainable and Smart Mobility Strategy and Zero Pollution Action Plan objectives.  

CRC Press has recently published a Handbook written by Christina Ludin-Brown and Ashleigh Filtness titled “Fatigue Management in Transportation”, which is designed as a comprehensive reference point, bringing together international expertise from leaders in fatigue science, and showcasing valuable insights from transportation industry practitioners. The 40 authored chapters of this handbook are divided into six sections, to better understand fatigue science, the consequences of fatigue in transportation, contributors to fatigue, managing fatigue and promoting alertness, real world case studies of fatigue management in practice, and future perspectives.   

The Global Alliance of NGOs for Road Safety (the Alliance) and the International Road Federation (IRF), with the support of the TotalEnergies Foundation program, have recently released the LEARN Guide, a new resource of information and support to empower road safety advocates globally. This guide is structured in six straightforward steps and enables NGOs and other road safety stakeholders to set up their own LEARN coalitions, benefiting from the tools and learning experiences of existing ones.      

The International Road Assessment Programme (iRAP) program on Star Rating for Schools and AiRAP partnerships will be scaled up to provide 3-star or better journeys to school and address road traffic crashes that are the leading cause of death among children and young people worldwide with the support of  Google. By using artificial intelligence to identify high-risk 1- and 2-star roads that children use on their journey to school, potential hazards and mobilise evidence-based upgrades that will save children’s lives will be identified. 

A paper titled “Real-Time Monitoring of Driver Distraction: State-of-the-art and future insights” authored by Eva Michelaraki, Chistos Katrakazas, Susanne Kaiser, Tom Brijs and George Yannis, has been published in Accident Analysis & Prevention. The aim of this research is to critically review and assess the state-of-the-art systems and platforms measuring driver distraction or inattention. The results indicated that real-time eye tracking systems, cardiac sensors on steering wheels, smartphone applications and cameras were the most frequent devices to monitor and detect driver distraction. On the other hand, less frequent and effective approaches included electrodes, hand magnetic rings and glasses.   

A paper titled “COVID-19 and driving behavior: Which were the most crucial influencing factors” authored by Marios Sekadakis, Christos Katrakazas, Eva Michelaraki, Apostolos Ziakopoulos and George Yannis, has been published in Data Science for Transportation. Based on the collected data, XGBoost feature analysis algorithms were deployed to obtain the most significant factors. Results revealed that COVID-19 new cases and new fatalities were the most significant factors related to COVID-19 metrics impacting driving behavior. In addition, the correlation between driving behavior with other factors (i.e., distance traveled, mobile use, driving requests, and driving during risky hours) was revealed. Lastly, the differences and similarities of the harsh event rates between the two lockdown periods were identified. 

The Global Alliance of NGOs for Road Safety launched, with the active contribution of NTUA, an accountability toolkit, which is a set of practical, web-based tools. It offers tangible steps to equip NGOs to hold their governments accountable for the safety of all road users by reducing road deaths and injuries by 50% by 2030, in alignment with the Global Plan for the Decade of Action for Road Safety 2021-2030 (Global Plan). The toolkit is a practical resource for NGOs and other civil society advocates and is underpinned by five Priority Interventions that have been proven to be among the most effective in reducing road deaths and injuries.

An NTUA Diploma Thesis titled “Fuel price impact on driver harsh behaviour improvement in Greece” was recently presented by Panagiota Konstantakopoulou. It analyses the impact of fuel price on driver behaviour and explores how price changes can influence driving style, abruptness and speed. The research includes statistical data of fuel prices and driver behaviour for the years between 2019 and 2022.   The increase in fuel prices has led to a reduction in sudden acceleration/deceleration. It was observed that during periods of increased fuel price, drivers improved their driving style and were more attentive to the task of driving, performing fewer abrupt events.  

An NTUA Diploma Thesis titled “Impact of road safety culture elements on road crash risk in Greece” was recently presented by Nikolaos Veneris. In order to achieve this, data from the “Safe Culture” research regarding private car and motorcycle drivers in Athens and Rhodes were exploited. Subsequently, the answers from questions that serve the purposes of this thesis were picked and classified, in order to develop binary logistic regression models. Results indicate that drivers probably understand the importance of more intensive traffic enforcement as a means of traffic accident reduction, the development of a common road safety culture in the island of Rhodes in contrast to that of Athens and, last but not least, the importance of factors such as driving frequency, age and experience, on traffic accident probability.   

An NTUA Diploma Thesis titled “Correlation of crash risk with driver capacity in coping with driving tasks complexity using machine learning” was recently presented by Spyros Tsigkos. A large set of  driving data under real-life conditions in Great Britain was exploited and eight Structural Equation Models (SEM) were developed. It emerged that increasing the complexity of the trip increases the risk of a crash, while the deteriorated condition of the driver and the vehicle leads to increasing the crash risk. Male drivers have more high-severity abrupt incidents while driving compared to female drivers, which confirms the international literature.   

An NTUA Diploma Thesis titled “Economic assessment of free public transport in Athens” was recently presented by Chrysavgi (Chrysa) Vagdatli. For this purpose, a social-economic analysis, in the context of a Cost Benefit Analysis (CBA), was conducted to assess the socio-economic impact of the FPT, up to the year 2030. In the framework of the CBA, four Scenarios for reduction of public transport tickets were examined. Consequently, a multinomial logistic model was developed to investigate for each of the three Scenarios the level preferring Athenians the FPT over private car, using data from a stated preference questionnaire survey. This social-economic analysis demonstrated that the introduction of FPT in Athens can contribute to social welfare mainly due to the modal shift from private cars to public transport.   

The World Road Association – PIARC recently published two Reports titled “Road Safety in LMICs: Identification and Analysis of specific Issues” in two parts Literature review and Illustrative Examples. The first part starts from the notion that road safety is a multifaceted problem which requires a multi-disciplinary approach. The safe system approach is generally considered as the central concept for this purpose and this starting point is also taken in this study. The second part is a follow up of an earlier literature review, in which were indicated which specific issues do need further attention in LMICs in the coming period up to 2030.  

The World Road Association – PIARC implemented an ambitious PIARC Knowledge Exchange project, aiming at sharing knowledge about road safety, with the active contribution of NTUA, especially within Low and Middle Income Countries with limited resources but also in more developed economies with different needs and priorities. The theme of this month refers to Vulnerable Road Users (VRUs), as presented by the PIARC Technical Committee 3.1 member Lawrence Chauke. Throughout the year, PIARC will focus on the Safe System approach, addressing safe roads and roadsides, safe road users, safe vehicles and safe speeds.   

A paper titled “The impact of cognition-affecting neurological diseases on reaction time and driving speed deviation” authored by Athina Diamanti, Apostolos Ziakopoulos and George Yannis, has been published in Open Transportation Journal. Analysis of cognitive impairments based on GDS questions showed that frequent ‘feelings of boredom’ correlated with a 7% increase in reaction time and a 8% increase in the standard deviation of driving speed. Conversely, ‘feelings of worthlessness’ reduced the standard deviation of driving speed by 4.5%. ‘Feeling full of energy’ contributed marginally significant increases to reaction times of 4%. Drivers with Alzheimer’s and Parkinson’s diseases showed higher reaction times, while drivers with depression and the control group showed lower reaction times. Drivers with Parkinson’s disease showed statistically fewer deviations of average speed. This research showed that cognitively impaired individuals have larger reaction times and more erratic driving speeds.
