This paper discusses the ongoing development of a new high resolution traffic emissions and fuel consumption model for Australia and possibly New Zealand, as part of a modelling framework that contains other models for more aggregate scales (e.g. fleet composition model, average speed model). A high resolution model is needed to adequately address increasingly complex policy questions underpinned by various developments in the international arena, for instance with respect to input and emissions test data. Preliminary results are discussed showing that the new modelling approach appears to deliver good results in terms of model accuracy, reliability and robustness. It is believed that model performance can be further improved by exploring other options. It is also important to examine the performance of other model structures (e.g. simpler or more complex models) and further examine the interactions between availability and quality of input data, level of model detail and overall prediction accuracy.
