The main goal of these lines was to remove a vast number of bus routes from the Athens city center, which was heavily affected by traffic congestion at the time.
This scheme was created only for distant suburbs of Athens such as Agios Stefanos, Vouliagmeni, Paiania, Ano Liossia and Mandra.
In suburbs near the city centre, such as Ilioupoli, Vyronas, Psychiko and Galatsi, there was not any factual change on the bus routes.
