Suggestion for Transportation problems in Bangalore - 2

Ok, I have second thoughts about multiple airports. Well, I still stick with major, international at Devanhalli and smal domestic one at Electronic city. Thats enuf.

Now don't turn bangalore into another west coast US city. Plan ahead for mass transport. Use the help of major industrial companies as BHEL, ISRO, BEL, colleges such as IISc to come up with instruments to make underground or elevated rail system. Only elevated won't help. It has to be mixture of both. Make them so that people don't need to commute by their own cars or bikes. People should choose these mass transits.
