An Integrated and Multidisciplinary Approach for Studying Use and Acceptance of New Driver Support System: The French National Project on Intelligent Speed Adaptation (LAVIA Project)

Speeding on the roads is acknowledged as a serious societal and public health issue in all countries. During the last twenty years, much research has been devoted to studying the potential impact of new driver support system, such as Intelligent Speed Adaptation (ISA) systems for contributing to solve this issue. The aim of this paper is to present the multidisciplinary and integrated evaluation process of the French project on ISA (the LAVIA project). The LAVIA systems were evaluated on the basis of four main dimensions: usability, usefulness, acceptability and safety. Definitions of the four dimensions are given and the survey, measurement and observation methods that were employed to evaluate them are presented. The main results obtained and their contribution to the overall evaluation process are presented and discussed.
