Eco-driving has been shown to be a very efficient driving technique to reduce consumption and CO2 emissions into the atmosphere. This paper investigates firstly, depending on the road type of each route studied and its level of service, how eco-driving affects the fundamental driving parameters through a field test in Caceres. Secondly, presents two steps of analysis regarding the ¨effectiveness¨ of eco-driving. The first step is to conduct a factorial analysis in order to underline the theoretical parameters related to fuel consumption and road conditions. On the second step, the effect of experimental condition like traffic state, road slope is examined and ordered by means of regression analysis. The first part of the research concludes that maximum speed is always lower in any road type when driving in eco mode. The eco-driving, therefore, helps to limit the excesses of speed in these types of roads. Average rpm is always lower in eco mode than non-eco. As the level of service is lower, the average rpm decreases are also reduced. Negative accelerations are lower in eco mode than non eco. This produces a more comfortable driving and a lower fuel consumption. The second part of the research revealed a strong and significant relationship between independent variables and fuel consumption. The analysis of beta standardized coefficients shows that the fuel consumption is strongly affected by the road slope. Besides, more congestion and more RPM were associated with an increase in fuel consumption. Conversely, less negative acceleration, more speed is associated with a decrease in fuel consumption along the trip in urban area.
