Can eco-driving techniques make driving more economically and ecologically?

Eco-driving means to change driving styles to be more economically and ecologically beneficial. However, there are quite different opinions from different studies regarding the effects of eco-driving. Furthermore, most of the previous studies have been based on computer simulations. It is necessary to propose really effective driving styles in order to promote eco-driving. The authors conducted a group of test runs on public roads under normal traffic conditions. This paper reports the results of the studies and gives suggestions to promote eco-driving.
