Kledus, R.: Comparative Perception of Objects by Drivers from Stationary and Moving Vehicles in Regular Road Traffic. 19. EVU Conference, Prague

This article deals with the issues of determining the distance at which drivers can, in reduced visibility, first notice a pedestrian in the road. This is important for clarifying and assessing serious traffic accidents such as collisions between vehicles and pedestrians. Since experts can only measure the distance at which one can see a pedestrian from a stationary or slowly moving vehicle, it is important to study the difference in perception of objects by drivers from stationary and moving vehicles. However, this necessary research has, so far, not been conducted, the reason being that no suitable measurement method has been available which would enable one to measure the distance between an object on the road and the vehicle at the moment when the driver notices the object. This limitation has now been overcome by using, for determining the moment the object is seen, a measurement of the change in the driver’s direction of vision. Used for this purpose is a special device developed by viewpointsystem R, GmbH. The distance between the vehicle and the pedestrian is subsequently determined from the vehicle’s speed and the time taken to cover that distance.
