On the Design of In-vehicle Advice System

Over the past two decades of years, technological developments have taken place in the field of transportation. Many research and development institutes have been devoted to designing new support systems and in-vehicle information systems to encourage safe, comfortable and convenient maneuvering. This paper deals with the issue of designing in-vehicle advice systems for safe maneuvering, especially by focusing on long-distance commercial vehicles. The authors introduced the characteristics of driving domain. By using the skill-, rule-, and knowledge-based behavior model, the authors analyzed behavior characteristics of drivers, and proposed some basic principles of advice system design to support these three levels of behavior. This proposal will help researchers to identify what advice should be provided and when to be provided. A field study was carried out to support this proposal. The relations of maneuvering characteristics and the driver´s status were investigated to discuss about advice on a rule-based behavior. The authors hope that this work will promote further design-oriented discussions on in-vehicle advice system development.
