This paper analyses the welfare implications of information provision with random road traffic congestion. The results show that, information provision will generate positive and negative internal and external effects both to the informed and the uninformed drivers and will lead to a Pareto improvement.

In the January 1968 issue Mr Thomson concluded that the true capacity of the central London main road network had actually fallen since 1960. He now replies to some contradictory figures produced by the Chairman of the Greater London Council Highways and traffic Committee.
