CRITICAL SPEED IN PEDESTRIANS’ RELATIVE MOTION REGARDING LIMITED VISIBILITY ZONE FROM DRIVER SEAT

Safe driving is related to the choice of speed by automobile drivers according to atmospheric conditions, as well as when driving in zones of both reduced visibility and of limited visibility. Reduced visibility is associated with natural phenomena, such as fog, rain, snow, darkness, etc. Limited visibility is related to objects located on the traffic lane and near it, as well as topography of the area that obstruct the visibility of the driver. This paper outlines a dynamic study of a significant problem in driving connected with limited visibility from the driver's seat due to automobile interior equipment. The research was done implementing experimental and numerical study, obtaining the relative motion of a zone of partially limited visibility from the front left and right car pillars in relation to the trajectory of the pedestrian. At the moment of pedestrian detection, they fall into the danger zone for the car.
