| Abstract | Some of the issues complicating the statistical analysis of vehicle emissions and the effectiveness of emissions control programs are presented in this article. Issues discussed include: the variability of inter- and intra-vehicle emissions; the skewness of emission distribution from in use vehicles; the difficulty of obtaining statistically representative vehicle samples; the effect of repeated testing on a subset of the vehicle fleet; and, differences among common test methods and pollutant measurement devices. The article discusses the relevance of these issues in light of the following regulatory purposes: compliance testing of in-use vehicles that have certification standards; effectiveness evaluation of inspection and maintenance programs of vehicles; and emissions inventory estimates for air quality modeling and compliance planning. The article also provides a brief history and description of common vehicle emission tests. |
