This report is a revision of a 2001 report on trends in the emission of air pollutants from on-road motor vehicles. The current study uses 2000, 2001 and 2002 datasets for vehicle miles traveled (VMT) by vehicle type. The total emissions of carbon monoxide, hydrocarbons and nitrogen oxides from on-road motor vehicles for the period 1990 to 1998 is calculated for each dataset. Comparison of the three datasets shows that although there are differences in all three sets, the differences between the 2000 and 2002 datasets are relatively minor compared to the 2001 dataset. After a discussion of the differences between the three datasets, the most recent dataset is used to calculate the emission of air pollutants by on-road motor vehicles in Florida between 1990 and 2000. An attempt also is made to predict trends in emissions at the county level through 2005. Based on the most recent data, the report shows that emissions from on-road motor vehicles have generally declined for Florida in the past decade and will continue to decline. The report shows that in most areas, improvement in on-road motor vehicle emission rates have offset increases in VMT, changes in vehicle composition and increases in population. The modeling results show that these trends are likely to continue in the next 5 years. The report also shows that some areas in Florida that have traditionally not had air quality problems are experiencing a substantial growth in emissions from on-road motor vehicles. The model used in this report illustrates that the emission of air pollutants by on-road motor vehicles is influenced by four separate variables: VMT, emission factors, traffic flow and population changes. This model, with its relatively simple form and calculation methods, could be a valuable tool for analyzing trends
