The Panacea for all Traffic Evils- Road Widening?

Solutions: Many people, even some in authority believe that road widening is a panacea to all traffic chaos. ???

What could Road Widening result in?

Traffic engineers often compare traffic to a fluid, assuming that a certain volume must flow through the road system. But urban traffic may be more comparable to a gas that expands to fill available space (Jacobsen, 1997).
Empirical evidence unequivocal over a rather counter-intuitive result: Additional road construction results in more traffic congestion. Induced traffic basically means that the city cannot build its way out of the problem. While additional road construction may lead to a temporary reduction in traffic levels, this free additional space eventually attracts road traffic especially when there is latent demand for private vehicle usage.

The above does not mean that Road Widening is NOT REQUIRED AT ALL or SHOULD NOT BE RESORTED to but it simply means that the issue needs to thought through more carefully and a decision needs to be taken.

If we have the pedestrians out of the carriageway, definitely the traffic chaos will reduce and the flow of traffic will be smoother.
