In the frame of the European Safety Program PROMETHEUS, PSA Peugeot Citroen had since 1989 a common action with INRETS-MA and L.A.B., aiming at the specification and development of active counter-measure systems likely to help drivers to avoid the accident in the most frequent road fatalities circumstances.
The first part of this program, presented at the 13th ESV conference held in Paris in 1991 (S4 W 15), consisted in the in-depth analysis of a selection of representative accidents and in the reflexion on possible prevention strategies.
The second part of this program, presented here, is the validation of two of the counter-measures developped by PSA : Interactive road Signalling System-ISIS-and Automatic Guidance System, through experiments at actual accident sites, under the conditions of the accidents in question.
Three typical accidents : loss of control in curve, collision in curve and at a crossroad, are selected for detailed presentation, theoritical kinematic reconstruction and actual counter-measure testing, in the conditions of the initial accident.
The results (illustrated during the conference by a video) show adequation 0f the systems to selected cases.
A partial impact study of Automatic Guidance System application on curve severe accidents breakdown concludes this presentation.
