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.
