SOME OUTSTANDING PROBLEMS IN THE CAUSAL MODELLING OF CAR OWNERSHIP AT THE LOCAL LEVEL

This paper discusses a number of matters which are taken to be the most important outstanding problems in car ownership modelling at the local level. The specification of the income variable is considered since, although it is generally agreed that income is the dominant influence on car ownership, there are a variety of views on how the variable should be incorporated. The interdependence of the household's car ownership decision with many of its decisions is discussed in order to highlight the limitations for forecasting of even the best single equation model. Some of the problems of using dummy and surrogate variables are discussed. A large portion of the paper is devoted to the choice and implementation of calibration procedures, illustrated by results using data from West Yorkshire. /TRRL/
