There has been a lot of discussions going on about the many bus routes running in Bangalore which is one of the main point for not using a bus.
The existing bus routes may be many but the same are not confusing. A proper analysis reveals the area wise classification of bus routes. The buses in a series may be single suffixed or double sufixxed but there is a common point i.e they will follow a particular route and in case of a deviation will have a particular destination. This is with respect to the blac board or red board routes of Bangalore.
Another point which can be noted is whenever there is a deviation we can always see another route No. displayed below the actual route No. indicating which route the bus is going to take.
Eg: 363-372 all buses go on Bannerghatta Road and will atleast touch Bilekahalli. checking out with route No. 364A it has mention of 25E below it meaning it will follow route of 25E till the point it meets Bannerghatta Road(Jayadeva). Similarly 343-362 take Hosur Road. But buses like 343B,348G,356Q have a mention of 25A below it meaning it will take the route of 25A till it meets Hosur Road. (silk Board)
