A paper titled “Autonomous Vehicles in Urban Networks: A simulation-based Assessment” authored by Athina Tympakianaki, Leyre Nogues, Jordi Casas, Mark Brackstone, Maria Oikonomou, Eleni Vlahogianni, Tamara Djukic and George Yannis has been published in Transportation Research Record. A combination of microscopic and macroscopic simulations as well as statistical methods are applied. The results indicate a positive impact in relation to capacity changes resulting from the presence of Autonomous Vehicles (AVs) which vary with penetration rate. Analysis of three different urban networks, Barcelona, Bilbao (Spain), and Athens (Greece), reveals consistent trends.
