User acceptance of an eco-driving support system

Abstract

In this study an eco-driving support system was evaluated within a driving simulator study. The presented system was able to communicate with traffic lights and to detect traffic signs. On the basis of this information the system gave recommendations to the participants concerning fuel efficient gear shifting and acceleration/deceleration behavior. 30 participants drove different scenarios (traffic light approach, curves, and stop signs) with and without the eco-driving support system. Thereafter they answered acceptance questionnaires based on the Technology Acceptance Model concerning the system. Overall the acceptance of the system was very well. Yet, for some participants in the stop sign and curve scenarios the intervention of the system was too early.
