Konstantina-Aikaterini Mavraki, “Critical factors of road users’ self declared behavior and safety in Greece”, Diploma Thesis, NTUA, School of Civil Engineering, Athens, March 2026.

The aim of this Diploma Thesis is to investigate the critical factors of self-reported behaviour and safety of road users in Greece. Critical behaviours are 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. The analysis is carried out using descriptive statistics and binary logistic regression, with six separate models for different categories of road network users. In addition, the results of the ESRA survey are compared with field measurement data in order to highlight differences between self-reported and observed behaviour. The results indicated 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. Moreover, the inconsistency between self-reported and observed behaviour is more pronounced in practices that depend primarily on individual attitudes and risk perception, rather than in behaviours that are strictly regulated by the legal and social framework. Lastly, recommendations that could enhance road users’ safety, such as educational and training campaigns and targeted infrastructure interventions are provided.
