Perceived usefulness of eco-driving assistance systems in Europe
Assessing the perceived usefulness of eco-driving assistance systems is of high interest for system developers and researchers in the development stage of such systems. This applies especially to systems that try to influence the driver's behaviour in everyday situations and generating their greatest benefit if regularly used. This study presents results of a survey simultaneously conducted in 11 European countries with more than 5000 respondents aiming at collecting needs and requirements for future eco-driving assistance systems. Such systems have the potential of changing driving behaviour in the long run for supporting a more fuel-efficient driving and reducing emissions caused by motorised traffic. Three different driver assistance systems are considered covering inefficiencies in pre-trip, on-trip and post-trip situations. Each system is assessed according to the factors of perceived usefulness, the expected environmental impact and the user's willingness to pay for it. The study will show that in general car drivers welcome the deployment of eco-driving assistance systems and rate them as useful. It likewise demonstrates that the acceptance of additional costs for the user is very low.
