To be honest I am not sure if the name of this place is Sara-e-Mili Bus, but there is a large area for buses and other vehicles. It is exactly at the opposite side of Rasalat Alley. As far as I am concerned, This exact place is known as Ghazni Station from which people travel to Ghazni. Almost all types of vehicles are available here and lots of people take their journey to Ghazni from here.
Hope it be helpful.
