Some new fuel and emissions models for different vehicle types have been developed, based on the Biggs-Akçelik hierarchy of fuel consumption models. The models extend the set of available models to include 4-cylinder and 6-cylinder EFI passenger cars running on unleaded petrol. Models for individual vehicle types may be combined to yield models for the performance of a traffic stream. The models allow detailed investigation of the effects of traffic congestion on fuel consumption and emissions. The models may then be incorporated into transport network performance studies, as tools for use in the prediction of environmental and energy impacts of road transport projects, from the individual intersection to the metropolitan level. The role of the traffic stream models in environmental impact analysis is indicated, through the development of the IMPAECT supermodel.
The energy and emissions models yielded by this research are for modern unleaded petrol vehicles. They thus enlarge the set of known models of passenger vehicle performance, for use in traffic engineering and transport planning applications. The models in the paper are the first comprehensive results of the project. Further work has still to be reported, and this will further enlarge the set of available models.
