An effective way to reduce fuel consumption in the short run is to induce a change in driver behaviour. In this project, a new-generation fuel-efficiency support tool has been designed. The support tool includes a normative model that formulates optimal driver behaviour minimising fuel consumption. If actual behaviour deviates from this optimal behaviour, the support tool presents advice to the driver on how to change driver behaviour. Evaluation of the new support tool by means of a driving simulator experiment revealed that drivers were able to reduce fuel consumption by 16% compared with 'normal driving' and by 7% compared with driving fuel-efficiently without support. Within the urban environment, reductions of up to 23% were found. In addition the new support tool was evaluated with regard to secondary effects. (A*)
