The Mobility Unit of DG GROW of the European Commission has recently released a Report titled “Study on the need for harmonised rules to support the rise of micro mobility and increased road safety for personal mobility devices” prepared by Transport Research Laboratory (TRL) and FKA GmbH. This report emphasizes the importance of accurate and harmonized data to support evidence-based policymaking and the achievement of Vision Zero targets. The study concluded that enhancing data quality and consistency could reduce road fatalities by up to 50% in some areas, as better data allows for more targeted interventions. The study also highlights gaps in existing data systems, with a particular need for improved reporting on vulnerable road users, such as pedestrians and cyclists, who account for a significant proportion of road fatalities in urban areas. By addressing these challenges, the EU aims to foster a unified approach to road safety, leveraging innovative technologies and methodologies to ensure progress toward safer roads for all. 

A NTUA Diploma Thesis titled “Road Crashes Analysis In Greek Islands” was recently presented by Nikitas Maratos Filippidis. For this purpose, data on monthly arrivals, crashes, and fatalities were collected for 38 Greek islands, which were then divided into four groups based on their geographical location. Subsequently, these correlations were further examined through the development of Generalized Linear Models and Random Forest models using the R programming language. The results showed that arrivals on an island are positively correlated with the number of accidents and fatalities recorded during that period. Additionally, while arrivals were correlated with accidents across each group of islands examined, the results differed, possibly due to better road conditions on islands with high arrival numbers but low accident rates.  

A NTUA Diploma Thesis titled “Analysis of factors influencing traffic conditions changes in Athens” was recently presented by Evi Krini. For this reason, traffic data were collated from selected road segments in Athens, including traffic speed through Google Maps for 62 (road axes) and the hourly traffic volume at 26 points via the Centre for Traffic Management, covering the period from January to July 2022. Additionally, data on weather conditions were gathered, and the final database was completed with geometric road features. Subsequently a Machine Learning algorithm and Cluster Analyses were conducted. The application of the models revealed that traffic metrics are significantly related to the time and type of day (weekday/weekend), with peak traffic volume occurring on weekdays during morning rush hours. Moreover, an increase in temperature is associated with a decrease in traffic volume in the morning and an increase in the evening, while the presence of rain increases low volume of traffic and decreases high traffic speeds.   

A NTUA Diploma Thesis titled “Critical factors of safe micromobility in Greece” was recently presented by Anestis Gkiourtzidis. For this purpose,  descriptive analysis was conducted on a sample of 63 electric scooter users, and 9 binomial logistic regression models were developed based on data from the third edition of the international ESRA survey (E-Survey on Road Users’ Attitudes). The results showed that older users and those who recognize risks such as speed and lack of attention adopt safer practices. Social pressure within an area influences compliance with road safety rules, while women demonstrate more cautious behavior compared to men. Despite the mandatory use of helmets, many users do not comply, indicating the need for stricter enforcement and education. Based on the findings, several recommendations are proposed to improve the road safety of electric scooter users, including stricter law enforcement and targeted improvements to road infrastructure.  

A NTUA Diploma Thesis titled “Analysis of drink and drive on driven behavior and safety in urban environment” was recently presented by Themis Bouropoulou.  To achieve this goal, an experimental procedure was conducted using a driving simulator, through which the driving data of 35 participants were collected. To complete the necessary data collection, participants’ characteristics were also determined through a questionnaire survey. The analysis of the results was done through statistical analysis, specifically by developing statistical models using linear and binomial logistic regression. The main conclusions are that as the amount of alcohol in the body increases, the likelihood of an accident in an urban environment also increases. The distance from the vehicle ahead decreases as alcohol consumption increases. Finally, as the alcohol level in the body rises, the driver’s average reaction time to potential obstacles also increases.  

A NTUA Diploma Thesis titled “Safety Impact Investigation of an automated shuttle service based on network traffic simulation” was recently presented by Maria Takka. For this purpose,  three scenarios were carried out that differed in terms of the percentage of conventional and autonomous vehicles. For data analysis, polynomial logistic regression models were developed for each scenario. The results showed that the speed limit, the maximum deceleration of the second vehicle, the difference in vehicle speeds as observed at the minimum time-to-collision, the initial deceleration rate of the second vehicle, the type of conflict and the traffic capacity have a significant influence on the simulated hazard, which indicates critical conditions for the occurrence of a crash.  

A NTUA Diploma Thesis titled “Preferences of Public Transport passengers towards contactless bank card payments” was recently presented by Konstantinos Fotopoulos. To achieve this objective, data collection was conducted through a questionnaire with focused questions, completed by a large sample of commuters. Subsequently, binary and multinomial logistic regression models were developed. Results indicate that as the difficulties in purchasing tickets decrease and payment security is ensured, passengers are more likely to adopt the new payment and boarding system. In particular, those who seek information about the new system are more likely to embrace it, as they recognize its benefits. Access to information and familiarity with contactless payments play a critical role in strengthening their confidence, making them more open to new payment practices, such as using bank cards or digital wallets.  

A NTUA Diploma Thesis titled “Ιnvestigation of dangerous driving behaviour by exploiting naturalistic driving data” was recently presented by Eleni Theodoraki. To achieve this goal, useful data related to driver behaviour were collected through a naturalistic driving experiment in real-life conditions in Belgium and England combining machine and deep learning algorithms. The results showed that the most significant variables were the occurrence or non-occurrence of harsh acceleration and the occurrence or non-occurrence of harsh braking in Belgium and the total travel distance and the occurrence or non-occurrence of harsh acceleration in England.  

A NTUA Diploma Thesis titled “Critical factors of motorcyclists self-declared behaviour and safety globally” was recently presented by Dimitrios Oikonomou. For this purpose, five Binomial Logistic Regression models were used, exploiting data from the third edition of the ESRA survey (E-Survey on Road Users’ Attitudes). The five dependent variables used concerned riding without a helmet, riding under the influence of alcohol / substances, using mobile phone while riding, and exceeding the speed limit for moped and motorcycle riders. The statistical models confirmed that the independent variables in each model play a key role in self-reported behavior and motorcyclist safety globally. Gender stands out as an important factor, with men more prone to engaging in irregular behaviors. Another significant factor is environmental respect, as drivers who litter on the road are more likely to exhibit such behaviors.  

A NTUA Diploma Thesis titled “Analysis of eco-driving benefits in urban and highway environments using driving simulator” was recently presented by Maria Ioanna Sousouni. To achieve this objective, an experiment was conducted in a driving simulator, and 39 young people participated to collect road data.  The developed statistical models were related to carbon dioxide emission, carbon monoxide emission, nitrogen oxide emission and the accident probability. It was shown that eco-driving contributes to reducing the emission of carbon dioxide, carbon monoxide, nitrogen oxide and the probability of the driver being involved in an accident. The study showed that urban roads produce fewer pollutants than highways, but the risk of accidents is significantly higher, highlighting a major road safety concern.  

Τhe European Transport Safety Council (ETSC) has published the 47th PIN Flash Report titled “Improving Road Safety of E-scooters“. This Report calls for the development of mandatory technical requirements for all e-scooters sold in the European Union, highlighting the need for stronger road safety measures across Europe. Key recommendations include stricter e-scooter safety standards, such as a 20 km/h speed limit, to address rising urban safety concerns. Enhanced regulations aim to ensure safer roads for all users.
