Armira Kontaxi has successfully defended her PhD dissertation titled: The Driver Behavior Telematics Feedback Mechanism, under the supervision of NTUA Prof. George Yannis. Data from a 21-month naturalistic driving experiment involving 230 drivers across six feedback phases generated a robust dataset of 106,776 trips, covering 1.3 million kilometers. Advanced statistical and machine learning models, including Generalized Linear Mixed-Effects Models (GLMMs), Structural Equation Models (SEMs), and Survival Analysis methods (e.g., Weibull AFT, Cox-PH with frailty, and Random Survival Forests), were utilized to analyze behavioral metrics such as speeding, mobile phone use, harsh braking, and accelerations which demonstrated substantial impacts on reducing risky behaviors. Key findings suggest that the overall impact of feedback significantly improved driving behavior and safety, with notable variations across user groups and driving contexts. Urban environments demonstrated the most substantial reductions in mobile phone use and harsh events, likely driven by the heightened complexity and demands of navigating urban settings. These findings highlight the need for continuous and adaptive engagement strategies, incorporating diverse features tailored to the specific needs of different user groups and driving contexts, to ensure long-term effectiveness and sustained safety improvements.

The European Commission with the active contribution of NTUA, SWOV and KFV launched a safe mobility promotion activity focusing on vulnerable road users, providing in-depth analysis of road safety for cyclists, pedestrians, powered two-wheelers, and users of personal mobility devices. According to the new Reports from the European Road Safety Observatory, one key finding shows that infrastructure improvements, such as segregated bike lanes, significantly reduce the risk of serious accidents for cyclists. As for pedestrians, older individuals are disproportionately represented in fatality statistics. Powered Two-Wheelers face a significantly higher risk of dying on European roads compared to other motor vehicle users. The PMD report reveals a sharp rise in incidents involving e-scooters, particularly in cities and highlights the need to address aspects relating to the vehicle, infrastructure and rider behaviour to address this emerging challenge.

A paper titled Understanding the effects of underreporting on injury severity estimation of single-vehicle motorcycle crashes: A hybrid approach incorporating majority class oversampling and random parameters with heterogeneity-in-means authored by Nawaf Alnawmasi, Apostolos Ziakopoulos, Athanasios Theofilatos and Yasir Ali has been published in Analytic Methods in Accident Research. This study aims to provide an empirical assessment of the impact of underreporting issue using a hybrid approach in estimating injury severity for single-vehicle motorcycle crashes. Key results suggest that crashes occurring during slowing down or stopping are associated with lower injury severity, whereas negotiating a right turn increases the probability of severe injuries. Interestingly, crashes that occur on dry pavements are associated with higher injury severity when compared to wet pavements, likely due to rider behavior adjustments in adverse weather conditions to compensate for the risk.
