From technological acceptability to appropriation by users : Methodological steps for device assessment in road safety

[IF=1.964]International audienceThis article presents the methodology developed within the framework of the research project SARI(Automated Road Surveillance for Driver and Administrator Information). This methodology is based onthe logic of action research. The article presents the different stages in the development of technological innovation addressing vehicle control loss when driving on a curve. The results observed in speed reduction illustrate that no matter how optimal an innovation may be technologically speaking, it isonly as effective as it is acceptable from a user standpoint. This acceptability can only be obtained if thetechnology is developed by engineers in liaison with social science specialists
