Abstract


Participants in road traffic perceive their road and transport environment according to their abilities and motivation. Here, we must not forget that human organism has adopted to certain way of living and to the speed. In the last few decades we have been witnessing a radical progress; life is becoming faster, humans have trouble following this and it is not surprising that many fail - this is known as the human factor.
We are facing an increased drivers’ visual information overload of the road space; also with traffic signals, a multitude of important and less important information for the driver. Many times, there is an adverse effect achieved due to the excessive number of traffic signals, their inconsistency and unsystematic installation - the drivers are unable to perceive the whole information or they do not understand it. Consequently, this causes confusion and additional psycho-physical burden. The traffic safety of participants is thus decreased.
Since the driver’s cognitive and perceptive abilities are rather limited, he should only be 'burdened' by as many information as are necessary and essential for safe driving. Above all, attention should be paid that the perceived information from the driver is consistent with his expectations, that it draws his attention and can be easily read and understood.
Finally, we should not ignore the fact that people live longer, the elderly are healthier and consequently more active. By this, a proportion of older drivers has been increasing and their psycho-physical abilities decline significantly with age.
