>Congestion is a function of the capacity of a roadway, and the number of vehicles trying to use it at a given point in time. And driver behaviour. If drivers could rationally act for a collective good then congestions could be avoided or limited, of course until certain threshold. Problem is that this kind of behaviour is not taught and is not enforced. The best solution for congestion is limiting the need for driving through more intelligent city planning (and through possibility to work from home).
