The principle of selective perception |
|
According to the calculations of statisticians, a car driver needs to take in, process and react to the information of a traffic sign on average every 70 metres. Therefore, at a speed of 100 kph, every 2.5 seconds on average. Added to this are other demands made on the driver, such as weather conditions, road conditions, direction of the road, other road users, changing gear, braking, etc.

Stimulus situation: More Information than the motorist can deal with.

This permanent stress of assimilating information and acting on it is considerably intensified at night. The result is a dramatic reduction in acuity of vision to one twentieth of normal daytime performance. Obviously, the driver is then no longer able to take in important information because of the reduced field of vision, the considerably reduced contrast and the difficulty in recognising colours. Thus the danger of accidents grows.
