Abstract
Information reaching the driver from the road via the sense organs lead to measurable changes in responsiveness. For various reasons the result can be overloading of available capacity. Because of a high technical input the necessity for mustering the mechanics of the vehicle has already been reduced to a minimum. On the other hand, the stream of information about the environment is so comprehensive that is raises the question of a possible reduction in the density of information received. From the relevant medical viewpoint, the processing of internal information gains particular significance in a traffic context.
