The rapid technological advancement in the field of Transportation has brought autonomous vehicles to the forefront as an innovative and highly promising solution for improving road safety and energy efficiency. However, their successful and safe integration into the existing transport system largely depends on their acceptance by the drivers themselves. The present Diploma Thesis aims to investigate the acceptance of autonomous vehicles by Greek drivers, as well as their intention for future purchase, focusing on the factors that shape their attitude towards this new technology. Data collection was carried out through a properly designed questionnaire, which included hypothetical travel scenarios with varying parameters, such as safety, cost, and time, in order to capture users’ preferences and perceptions. The objective of the data analysis is to highlight the key factors influencing Greek drivers’ intention to either accept or reject autonomous vehicles. Subsequently, logistic regression models were developed, from which utility functions were derived to mathematically describe drivers’ behaviour toward autonomous vehicles. The results indicated that the acceptance of autonomous vehicles depends, among other factors, on cost, travel time and vehicle safety level. Specifically, increases in travel cost and travel time, as well as reduction in the level of safety, appear to reduce the probability of choosing autonomous vehicles. Furthermore, the high purchase price of a fully autonomous vehicle and the household income of the participants act as deterrents to their selection. In contrast, the availability of driver assistance systems (cruise control) in vehicles, as well as the driving experience of Greek drivers, emerged as particularly reinforcing factors. Finally, the need and possibility of being able to take control of the vehicle at any time increased the likelihood of choosing autonomous vehicles, positively influencing their acceptance.
