Work carried out within the RHTM project on the development and testing of the car ownership model is described. The work consisted of 3 stages: justification and development of the model using national data sources; calibration of the model using RHTM data; and testing the model's ability to reproduce observed data not used in its calibration, in the validation exercise, and in 1966 in back projection work. The demonstration of the model's stability over a 10 year period and its ability to reproduce the growth in car ownership over 15 years using economic variables, laid the foundation for the subsequent work. The second stage contained a number of advances in modelling methodology in respect of the selection of a stratifying variable and the choice of the number of strata using sound statistical techniques. The results of performance tests carried out in the third stage are discussed.
