If a junction is not centrally controlled then it can only adjust the timings for that junction based on the traffic flow though it. Yeah - I spent fifteen years designing traffic systems. It's one of those jobs that you just don't tell people what you do because it's guaranteed to get your eardrums ruptured.
As for all that honking of horns in India: it's not hot-tempered drivers. They're used as a warning that someone is about to overtake you or, if up on some of the seriously narrow roads in the Himalayas, to let you know that someone is coming the other way round the blind bend you're just approaching.
