A very interesting article on how traffic congestion can paradoxically increase on the additional of additional lanes and vice versa. Essentially it implies that by suggesting that an additional option is available to people, the existing system tends to slow itself down as everybody crowds to the same route. Traffic is something I have begun to understand quite well in the past years and this brings a new perspective it all.
