Fixed Route Bus lines are identified by number. 
Most buses displays a sign on the LED destination board (or behind the windshield) indicating its line number with a capital letter of the destination (e.g. 2S means the bus is bound for Sawata on Line #2, Minami Line). New vehicles have the LED destination board displaying line # with the destination in bilingual.
