Vehicle operating costs in 1973.

This report gives the latest version of the laboratory's formulae for vehicle operating costs. The only changes in the basis of the formulae relate to the treatment of depreciation and vehicle time saving and to tyre costs. Formulae are given for the operating cost per kilometre for traffic of an average composition for different classes of vehicle and also for the cost including all taxation. The costs given in this report relate to the end of 1973; since then there have been a number of changes. It is hoped that 1974 estimates will be available shortly. (Author/publisher)
