Abstract
A series of models have been developed to predict the emissions of fleets of vehicles under on-road driving conditions. Based on an analysis of a database for vehicular emissions data, emissions are calculated as a function of vehicle speed and accelerations. Models for cold start emissions and deterioration factors have also been implemented for petrol-powered passenger cars. Sample calculations and comparisons with emissions results from standard test cycles indicate that the models give a good prediction of the behavior of vehicle emissions as a function of driving patterns.
