A NTUA Diploma Thesis titled “Cost Benefit Analysis of 30 km/h speed limit implementation in all EU cities” was recently presented by Gerasimos Balatsinos. To achieve this objective, a methodological framework consisting a statistical analysis of road crashes and a Cost–Benefit Analysis at a macroscopic level were developed. Initially, road crash data recorded within urban areas for the period 2016–2022 were collected for each EU Member State. Subsequently, the data was utilized to develop two logistic regression models, incorporating fixed and random effects. The results indicate that crash severity is primarily influenced by the type of transport mode, lighting conditions, and age, while other factors exhibit a smaller yet statistically significant effect. Furthermore, substantial variation is observed across EU countries in terms of baseline risk levels. The findings suggest that the implementation of a 30 km/h speed limit constitutes an economically feasible measure at the European level, yielding a positive Economic Net Present Value (ENPV) of approximately €18 billion. At the city level, the ENPV ranges from approximately €90 million (Paris) to €4.6 billion (London).  

A NTUA Diploma Thesis titled “Critical factors of road users’ self declared behavior and safety in Greece” was recently presented by Konstantina-Aikaterini Mavraki. To achieve this objective, critical behaviours were analysed, such as compliance with speed limits, seat belt use, alcohol consumption, mobile phone use, etc., across different categories of users, including car drivers, motorcyclists, cyclists, pedestrians, and users of electric scooters. Six separate binary logistic regression models for different categories of road network users were developed, using also the results of the ESRA survey, which were compared with field measurement data in order to highlight differences between self-reported and observed behaviour. The findings suggest that individuals who agree with and accept risky and illegal road behaviours are more likely to commit violations of the Road Traffic Code across all examined categories of road users. Furthermore, recommendations that could enhance road users’ safety, such as educational and training campaigns and targeted infrastructure interventions were provided.  

A NTUA Diploma Thesis titled “Investigation of the acceptance of reducing the speed limit to 30 km/h in all urban areas in Greece” was recently presented by Konstantina Gkoudinakou. For this purpose, a special questionnaire was developed that was answered by 302 drivers based on the method of declared preference for 10 hypothetical scenarios with variations in time, fuel consumption, and the probability of a road crash with casualties. Data were collected, processed, analyzed, and after many tests, a polynomial regression model and two binary regression models were developed to understand the factors that affect the acceptance of drivers in a city center to reduce speed limits. The results indicated the variables that significantly affect driver acceptance, such as increased travel time, reduced fuel consumption, reduced likelihood of road accidents with injury, driving frequency, the role of speed in causing accidents, the role of pedestrians in choosing driving speed, and certain demographic factors. This way, findings are also obtained regarding the social acceptance of the measure in relation to the characteristics of the participants, such as gender, age, education, driving behavior, and so on.  

A NTUA Diploma Thesis titled “Investigation of the Perceptions and Acceptance of Greek Road Users towards the New Road Traffic Code” was recently presented by Nikolaos Spathis. For the purposes of this research, data collection was carried out through a questionnaire, which was completed by 800 travelers. Subsequently, binomial logistic regression and elasticity models were developed for Greece as a whole, for Attica, and for the other Regions of Greece. The results showed that acceptance is influenced by specific factors such as gender, age group, violations related to excessive speed, attitude toward behavioral change, hours of driving per week, as well as the belief that the 30 km/h measure within residential areas will reduce road accidents. The findings indicated that the majority of Greek drivers show a tendency to accept the new Road Traffic Code. Overall, the results indicate that acceptance of the new Road Traffic Code is shaped by a combination of demographic characteristics, driving behavior, and perceptions regarding the effectiveness of the implemented measures.

The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Speed and Speeding Thematic Report which emphasizes that driving at excessive or inappropriate speed is a major threat to safety on the road. It is estimated that 10 to 15% of all crashes and 30% of all fatal crashes are the direct result of speeding or inappropriate speed. It is also emphasized that safety systems in cars, such as intelligent speed assistance or electronic stability control can prevent speeding or reduce the consequences of speeding, while education and communication, in combination with and supporting other measures, are particularly important. Moreover, city-wide 30km/h speed limits and their enforcement has been shown to be the most efficient measure for quick reduction of crash and injury risks.  

The Editorial for the Special Issue Vehicle Safe Motion in Mixed-Vehicle-Technology Environment authored by Stergios Mavromatis, George Yannis and Yasser Hassan has been published in the World Electric Vehicle Journal. This Special Issue aims to advance knowledge on vehicle safe motion during this critical transition period by bringing together recent research on mixed traffic flow dynamics, safety assessment, and intelligent control strategies. Collectively, the papers in this Special Issue provide scientific insights and practical tools that support safer, more efficient, and more resilient vehicle motion in increasingly complex mixed-technology traffic environments. The findings suggest that connectivity-enabled strategies, predictive control, and cooperative decision-making can mitigate safety risks while promoting smoother traffic flow and reduced energy consumption, particularly in complex settings such as work zones, tunnels, and intersections. Moreover, AI-based perception and traffic monitoring emerge as key enablers for real-time traffic management and energy-aware electric mobility.
