Abstract

One key initiative to reducing the environmental impact of motor vehicles is to identify the number and types of vehicle in the vehicle stock which are likely to excessively contribute to air pollution. Such an assessment is dependent on quantifying vehicle scrappage which, in turn, relies on the provision of temporally consistent motor vehicle registration data. There exist a number of issues that adversely impact on the temporal accuracy of motor vehicle registration data. This paper identifies these issues and proposes a cost effective correction framework for motor vehicle registration time series data. An application to Australian data is used to demonstrate the efficacy of the framework, identifying the need to introduce an additional vehicle category into the data, adjusting annual vehicle counts and removing the erroneous incidence of the number of vehicles in a vintage class that increase substantially beyond 2 years after the year of manufacture.
