Hi rama krishana,
What you pointed out is a true fact. Our traffic problems have been increasing for the years. And Kerala has got more vehicle densities than any other states in the country, with the density increasing in a more rapid manner. It seems that if these roads are not expanded, by 2020, there won't be any transportation on the roads. It will be full of traffic blocks in the roads.
And the people can also do something to reduce these traffic blocks. Why we are using bikes for the nearest town, eventhough it's a walkable distance away. Many of the small traffic blocks are made large by the two wheelers due to their rush. We must understand that the two wheelers not only creates traffic blocks, but also leading to the loss of fuels. So it will be better if we switch on to public transportation systems like buses.
Regards
