Effective and Acceptable Eco-Driving Guidance for Human-Driving Vehicles: A Review

TL;DR

This review analyzes eco-driving guidance for human drivers, highlighting challenges in standardization, effectiveness, and acceptance, and emphasizes the need for adaptive, personalized systems to promote sustainable driving behaviors.

Contribution

It systematically reviews existing eco-driving guidance studies, identifies key challenges, and discusses future research directions for adaptive and user-acceptance-focused solutions.

Findings

Guidance design lacks standardization and consistency.

Factors influencing guidance effectiveness vary across studies.

Long-term motivation and user acceptance are underexplored.

Abstract

Ecodriving guidance includes courses or suggestions for human drivers to improve driving behaviour, reducing energy use and emissions. This paper presents a systematic review of existing eco-driving guidance studies and identifies challenges to tackle in the future. A standard agreement on the guidance design has not been reached, leading to difficulties in designing and implementing eco-driving guidance for human drivers. Both static and dynamic guidance systems have a great variety of guidance results. In addition, the influencing factors, such as the suggestion content, the displaying methods, and drivers socio-demographic characteristics, have opposite effects on the guidance result across studies, while the reason has not been revealed. Drivers motivation to practice eco behaviour, especially long-term, is overlooked. Besides, the relationship between users acceptance and system effectiveness is still unclear. Adaptive driving suggestions based on drivers habits can improve the effectiveness, while this field is under investigation.
