People prefer own transport mainly because they can travel directly by the shortest route non-stop to the school/college/workspot and back.To use public transport, one has to walk in the hot sun to the nearest bus stop, wait for the correct bus, somehow manage to get in, get down and walk again.some people have to take more than one bus.Because of the crazy one way maze, one has to walk to a different bus stop for the return journey.

It is certainly possible to provide a facility almost like own transport.Presently, sharing transport is limited to it/bpo computer savvy sector.But there are lots of other people who are not computer savvy, who do not have the time to log on to a computer ,etc (the bottom of the pyramid, to quote management guru c k prahlad) who would gladly join to form a transport pool.There may be so many people in an apartment complex traveling daily to the same place and back at the same time.They would probably be surprised to see familiar faces in the group and think "why didn't WE think of this ?"

not sure how and where to follow-up on this one....

The Bangalore Metropolitan Transport Corporation (BMTC) will be introducing three routes called K1, K2 and K3.

Here they should have extended K1 upto Cantonment Station.  Also integrating with METRO stations should have been taken care as many places, these buses will be playing close the METRO stations enroot.
