The total emissions model for integrated systems (TEMIS) program was developed at the Institute of Applied Ecology, Darmstadt, to provide an analytical tool for planners and decision-makers involved in formulating energy policy. In this paper, the first of two, the enhancement of the TEMIS framework to accommodate various transport and traffic situations is reported. A number of factors were identified as having an influence on vehicle fuel economy and emission characteristics. Determination of these factors has involved reference to results of published empirical studies where vehicle exhausts have been monitored under a wide range of driving conditions. The life cycle of bio-diesel (UK) as a transport fuel has been created within TEMIS as an example of modelling the complete transport fuel cycle. In addition, the effects of different driving conditions (cruising, acceleration, deceleration and idling) on emissions and fuel consumption have been considered by defining different TEMIS processes for each of these driving modes.
