A Diploma Thesis titled “Modelling Automated Vehicles’ Socio-economic Impact” was recently presented by Epameinondas Theodorakos. The aim of this Diploma Thesis was the development of a model that, by filling in the values for several parameters, could estimate the socio-economic impact of the automated traffic for different penetration scenarios, compare these scenarios results and demonstrate each parameters’ impact on the total cost. The model application results highlighted the crucial benefits of automated traffic and quantified the socio-economic parameters impact depending on the penetration scenarios and the reference year, with most important the role of cost of travel time.
