The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Personal Mobility Devices Thematic Report which mainly refers to the safety of electric scooters. This Thematic Report highlights that a high proportion of crashes with a PMD are caused by falls, that can lead to common head injuries and by increasing helmet use would prevent these injuries. Moreover, a series of specific countermeasures are suggested, such as an e-scooters ban from pavements, a lower 30 km/h limit in urban areas and training motor vehicle users to be prepared to interact with PMDs is equally important for micro-mobility safety.
A paper titled Driving Automation Systems Penetration and Traffic Safety: Implications for Infrastructure Design and Policy authored by Antonia Antonakaki, Maria Oikonomou, Thodoris Garefalakis and George Yannis has been published in Infrastructures. The study aims to evaluate the impact of Autonomous Vehicle (AV) penetration rates on traffic safety, through the use of microscopic simulation scenarios, utilizing multiple linear and multinomial logistic regression models. The findings highlight that higher AV penetration rates generally improve traffic safety, although the coexistence of conventional vehicles and vehicles equipped with driving automation systems introduces traffic heterogeneity, potentially influencing safety outcomes. These results suggest that while AVs have a positive effect on road safety, further analysis is needed to address the complexities introduced by mixed-traffic conditions.

A paper titled Explainable macroscopic and microscopic influences of COVID-19 on naturalistic driver aggressiveness derived from telematics through SHAP values of SVM and XGBoost algorithms authored by Apostolos Ziakopoulos, Marios Sekadakis, Christos Katrakazas, Marianthi Kallidoni, Eva Michelaraki and George Yannis has been published in Journal of Safety Research. This study aims to quantify the impacts of the COVID-19 pandemic on driver behavior as expressed by harsh accelerations (HA) measured from over 35,5000 naturalistic driving trips by smartphone telematics data using advanced machine learning algorithms, including SVM and XGBoost, combined with SHAP values. Key findings indicate that high speeding, total trip distance, and trip duration are associated with increased HA counts. Drivers perform more HAs on speeds between 30–50 km/h, while after 50 km/h, the contributions of speed lead to fewer HAs.

A paper titled Predicting risky driving behavior with classification algorithms: results from a large-scale field-trial and simulator experiment authored by Thodoris Garefalakis, Eva Michelaraki, Stella Roussou Christos Katrakazas, Tom Brijs and George Yannis has been published in European Transport Research Review. The study analyzed large-scale data from real-world driving and simulator experiments, highlighting that models can predict dangerous behaviors, such as speeding and harsh braking, with accuracy rates as high as 84%. The findings emphasize the importance of using data-driven approaches to anticipate and mitigate risky behaviors, which are a leading cause of road crashes. This research reinforces the need for innovative tools to create safer driving environments and reduce accident risks.
A paper titled Spatial analysis of telematics-based surrogate safety measures authored by Dimitrios Nikolaou, Apostolos Ziakopoulos, Armira Kontaxi, Athanasios Theofilatos and George Yannis has been published in Journal of Safety Research. This study investigates the effects of traffic calming measures such as speed humps, chicanes, and roundabouts on road safety, air quality, and noise pollution. The findings reveal that implementing traffic calming strategies such as speed humps, chicanes, and roundabouts can reduce traffic crashes by more than 25%, with a remarkable 40% decrease in severe injuries involving vulnerable road users, including pedestrians and cyclists. These measures also encourage safer driving behaviors by lowering vehicle speeds, which significantly enhances safety in densely populated urban areas.
