A great deal of work has already been carried out in the field of car ownership prediction and, owing to a combination of circumstances, the degree of research and publication of results has tended to accelerate in size and scope in recent years. Not only are the wider theoretical issues considered, but an attempt is made to examine the practicalities of the application of car ownership prediction at national, regional, local and individual (or household) level, with particular reference to the work of several (typical) local authorities. Even in the UK there are few aspects of life (and even death) which have not been affected by the growth in car ownership. Car ownership forecasts are a major consideration in assessing the future viability and role of public transport, especially in a situation in which quality of access is viewed on a strict commercial, rather than social, basis.
