Résumé / Abstract

AN AUTOMOBILE DRIVER WHO APPROACHES AN INTERSECTION WHERE ANOTHER VEHICLE IS ARRIVING, MUST CONTROL HER/HIS OWN TRAJECTORY WHILE ANTICIPATING THE MOTION OF THE OTHER VEHICLE. HERE VISUAL SIMULATIONS WERE USED TO TEST THE INFLUENCE OF THE ROAD ENVIRONMENT ON THE VISUAL ANTICIPATION OF A COLLISION MADE BY A DRIVER IN SUCH A SITUATION. THE VISUAL ENVIRONMENT AROUND THE INTERSECTION OF TWO STRAIGHT ROADS WAS VARIED. SUBJECTS HAD TO ESTIMATE WHEN THE OTHER VEHICLE WOULD ARRIVE AT THE INTERSECTION. RESULTS SUGGEST THAT IN INTERSECTION SITUATIONS THE ESTIMATION OF ANOTHER VEHICLE MOTION IS NOT BASED ON A MINIMAL VISUAL INFORMATION SUCH AS THE VEHICLE MOTION ITSELF BUT IS MORE LIKELY TO INVOLVE SEVERAL SOURCES OF INFORMATION INCLUDING ENVIRONMENT-RELATED CUES. THIS LEADS US TO THE QUESTION OF AN OPTIMAL RESTITUTION OF THE ROAD ENVIRONMENT IN SIMULATION CONDITIONS.
