As atool for this analysis, APCRA Model is developed to describe which effects are significant explainerfor automobility characteristics. The results of statistical analysis offer ample evidence thatautomobility cohort effects do exist, and interaction with other effects, such as residence area and ageeffects, have a great impact on household car ownership and auto use.
