BIG10 services deploy (Suvarna class of) buses branded in green and bottle green on 12 major corridors coming in from surrounding sub-urbs in the city - Hosur road, Bannerghatta road, Sarjpura road, Kanakapura road, Mysore road etc. These buses are run on a direction based concept where the commuter takes the next (high frequency, every 15 minutes) bus in his/her direction of travel, and if need be, makes a change over to another bus to reach the destination. The service terminates on different points on the radius of the city core, to avoid congesting the city centre.
