Bangalore has a lot of traffic and a lot of traffic jams.
How about regulating the flow a little better by using the FM. Why not a dedicated Radio-station for the Traffic Police. With some awareness campaigns about the frequency etc we can have a lot of traffic steering away from jams and producing a better flow.
Even better - give it to a private operator - and I bet this Radio Station would easily be the most tuned in among all FM's in quicktime.
