A paper titled E-scooter riders: A cross-cultural analysis of traffic safety attitudes and behaviors authored by Milad Delavary, Craig Lyon, Ward G.M. Vanlaar, Robyn D. Robertson, Dimitrios Nikolaou and George Yannis has been published in IATSS Research. This study aims to analyze the prevalence of self-reported risky behaviors across various demographic groups and regions, and to assess factors contributing to the likelihood of unsafe e-scooter riding behavior. To achieve this, data from the third edition of the E-Survey of Road users’ Attitudes (ESRA) were utilized, focusing on responses from 39 countries worldwide. This paper included descriptive analysis and also mixed-effects logistic regression models were employed. The findings suggest that younger individuals and males are more likely to use e-scooters and engage in risky behaviors. Key factors influencing or associated with these behaviors included previous crash involvement, student status, and permissive attitudes toward safety regulations. Furthermore the study highlights the need for targeted safety interventions that address infrastructural factors as well as behavioral factors, including demographic and attitudinal influences.

A paper titled Validating traffic simulation for crash risk assessment using field crash data authored by Maria Oikonomou and George Yannis has been published in Journal of Safety Research. This study aims to bridge the gap between simulation models and real-world safety observations, contributing to the advancement of more robust safety assessment methodologies. Utilizing Aimsun Next, simulation data were analyzed to extract traffic conflicts, which were then converted into crash risk levels, as well ass real-world crash data between 2017 and 2019. The analysis of simulation and observational data revealed two distinct clusters: roads with low and high crash risks, clearly distinguished with minimal overlap. The findings suggest approximately 87.7% accuracy in predicting road crash risk classifications through traffic simulation, confirming its reliability for safety assessment. This paper validates a framework ready for future research applications in scenarios where direct observation is impractical, enhancing road safety and guiding interventions within evolving traffic conditions and technologies.

A paper titled Mild cognitive impairment, Alzheimer’s disease dementia, and predictors of driving cessation: A 7-year longitudinal prospective study authored by Petros Stamatelos, Ion Beratis, Panagiota Hatzaki, Alexandra Economou, Nikolaos Andronas, Dimosthenis Pavlou, Stella Fragkiadaki, Dionysia Kontaxopoulou, Anastasios Bonakis, Leonidas Stefanis, George Yannis and Sokratis Papageorgiou has been published in Journal of Alzheimer’s Disease. This paper aims to identify predictors of driving cessation among patients with mild cognitive impairment (MCI) or mild Alzheimer’s disease dementia (AD). The 109 participants underwent a neurological, neuropsychological and driving simulator assessment with re-evaluations after 48 and 84 months including a structured interview with the patients and their caregiver. Primary endpoints were driving cessation, death and progression to dementia. The findings suggest that age, SVF and mTWT are significant predictors of driving cessation among MCI and AD patients. Furthermore, driving simulator may be a promising component of driving evaluation. 

At a recent podcast in 4NewMobility Leadership Talk, NTUA Professor George Yannis provided a technical conversation, hosted by Astrid Rohles, about 30 km/h speed zones which turned into something much bigger: a vision for healthier, safer and more human cities. He emphasized that speeding remains the norm in urban mobility, endangering lives, discouraging active travel and fueling pollution. From empirical results across 17 European cities to his personal 30 Marathons in 30 months campaign, Prof. Yannis made a passionate and data-driven case for a European-wide roll-out of this low-cost, high-impact measure.

The solution? A coordinated European approach:
- Make 30 km/h the default in urban areas
- Support cities with infrastructure redesign
- Pair soft nudges with smart enforcement
- Communicate, measure and repeat

A paper titled Eco-driving in rural areas: a sustainable approach to reducing emissions and enhancing road safety authored by Marios Sekadakis, Penny Kourenti, Thodoris Garefalakis, Apostolos Ziakopoulos and George Yannis has been published in Case Studies on Transport Policy. This study aims to examine the advantages of eco-driving in rural and mountainous rural settings by employing an experimental methodology and utilizing data collected from 39 participants across a range of driving simulation scenarios and their characteristics through a questionnaire survey. To achieve this goal linear and logistic regression models were implemented. The analysis revealed that eco-driving significantly reduces pollutant emissions reduces fuel consumption by 7%, and reduces the probability of crashes by 66.2%. Furthermore, the quantitative analysis confirmed that mountainous rural networks, due to their topographical complexity, are associated with higher emissions, increased fuel consumption, and elevated crash risk compared to flatter rural environments, highlighting the need for terrain-specific eco-driving strategies. These findings highlight the promise of eco-driving practices in improving environmental sustainability and safety, particularly in rural environments.
