Delicately balanced hues and shades are painting pictures in harmony with a
beautiful world. Reflected rays impressionistically are touching your inner
eye and make you listen to the symphony of colors. Gentle brushes of light
playfully dancing over the skies the clouds the hills make you feel happy
and may be - a little bit more than that. Just in case you were lucky enough
to look at a spot of peacefully untouched nature - being framed by the
borders of your visual field - Turning around it may occur to you that never
ending rows of 'daytime running lights' stir up some disharmonious
sensations. Or blind anger.
Since you know that DRL caused fatalities (and still does) among 'weaker'
traffic participants, predominantly children at pedestrian crossings (quod
erat demonstratum). DRL implies a Violation of the Obligation of Protection.
Article 3, the first cornerstone of the Declaration of Human Rights,
proclaims the right to life, liberty and security of person.
Following the 'experiment' TWO YEARS DRL in Austria the Ophthalmological
Society of Austria (ÖOG) banned DRL.
Accentuating (DRL) one group of 'traffic-relevant objects' makes all the
other objects less conspicuous - worst case- they might turn into
sub-threshold stimuli hence escaping attention - to be �overlooked� -like
other non-accentuated objects in traffic scenarios (side impact- and/or rear
end- crashes). Reflecting materials (another attempt to improve safety of
the 'weaker group') are inefficacious in connection with DRL.
Distracters (DRL) provoke problems. Seeing, perceiving and recognition have
to be differentiated.The driver might see a child crossing the street. Its
image may be focussed at retinal level, the visual pathways functioning
perfectly would send the signal to the visual cortex. In spite of all that
it may happen that this very �traffic-relevant� object virtually disappears.
A number (~> four) of distracters (DRL) can cause capacity (and/or even more
complex -) problems of the visual short term memory (VSTM). Emphatically the
driver might repeat ever so often: �I did not see the child ! I swear it!�
Wrong. He saw the child, though he could not perceive it. The pedestrian
crossing seemed to be empty.
The phenomenon described above belongs to a group of cognition- and
recognition failures: �Change blindness, inattentional blindness, sustained
inattentional blindness, repetition blindness, disturbance of the �gist� of
a scene� etc. Over millions of years our visual pathways and visual centres
together with our complete central nervous system were conditioned to
function and react adequately within a natural environment as it is
described nostalgic/poetically in the introduction of this article. Ever so
often mankind tries to improve nature without giving sufficient thought and
consideration to all the complexity of a dynamic system. Clumsily he
disturbs and destroys the delicately balanced equilibrium. Usually such
simplifications (like DRL) are simple, straight - and wrong. Unfortunately
increased attention and/or training cannot prevent those cognitive
deficiencies caused by too high numbers of various distracters.
Dipped headlights and/or special (fog- etc) lamps are contraindicated during
daytime light conditions. The human sensory physiological system requires
exclusively dipped headlights or special headlights (fog etc.) under the
conditions of reduced sight. The reason: All the other �traffic-relevant�
objects, even resting traffic have to be caught and illuminated by the beam
of the headlights in order to avoid sub-threshold stimulus conditions. DRL
does not improve traffic safety. At no time of the day or the night, at no
season, at no geographical latitude or height, even in countries of the
extreme north or south DRL can be justified. The laws of sensory physiology,
cognition psychology and brain research are valid at any time and anywhere
on this planet.
RESUMÉ: REDUCED SIGHT: (DIPPED HEAD-) LIGHT
DRL: NOT JUSTIFIED
EPILOGUE:�Modern� headlights (without automatic adjustment-system�) and
street lamps are causing glare and prolonged retinal recovery following
light �stress�. The amount of highly energetic blue light is increasing
within the spectrum of these lamps thus causing irritation and even problems
for the environment (The Plight with Light). It is suggested to revise the
philosophy of light designing engineers. Within short time DRL contributed
to the climatic change like any other energy wasting measure. At the cost of
the next generations (delayed onset) again.
