IDNES.cz editors tested whether a
reflective element can save a pedestrian's life. It turned out to help
surprisingly a lot. A walker with a belt can be seen at three times the
distance than a walker in casual clothing. This gives the driver valuable
seconds to react.
One would say an ordinary striped
belt. When I held it at dusk in an alley near the village of Ořech near Prague,
I almost doubted it would be of any use to me. But in the dark, only the
headlights of the car brighten from afar, the tape suddenly lights up.
Together, the Ministry of Transport
and the Traffic Police have proposed that all pedestrians who are moving in
poor visibility on the side of the road without streetlamps be wearing the belt
the following winter.
The relevant law has already been
written and approved by the Ministry in the second half of the year.
Do you think that the introduction of
mandatory pedestrian reflex accessories is a good idea?
Together with the cameraman, we made
three measurements. We started by trying to find out how far the unlit
pedestrian driver would see. Followed by an experiment with a two-piece reflective
tape wrapped around the sleeve and the foot. For the third time, I put
on a reflective vest used by road workers, for example.
The predecessor of the current head of
traffic police Leos Trzil toyed in interviews with the idea that pedestrians
should wear a vest. However, his idea went down because no one wanted to walk
dressed as a worker on highway construction.
So in my first attempt, I went as an
unlit helper along the verge and the cameraman in the car was supposed to stop
when he saw me. Then I measured the distance between my position and my car
using the application on my mobile and GPS. We have verified the distance by
stepping.
It was just before eight o'clock in
the evening, not quite dark yet. It turned out that I was seen 50 meters in
front of the car, thanks to the fact that it was still dark and I had red
pants. You can see them better than dark ones.
The second attempt took place with a
reflective tape a few minutes later in the regular darkness. The measured
distance was 147 meters. I thought the car was a safe distance from me.
Therefore, a pedestrian with a belt
can be seen at three times the distance. At first, the driver sees only light
flashing around. The reflective
vest is then a
guaranteed protective device visible at a distance of 289 meters.
Pedestrian visibility affects many
things, of course, the speed of the car. The cameraman drove slowly against me,
but a driver running in the '90s might see a small spot in the dark later.
Also, it is approaching faster.
Even more useful is the usefulness of
tape when time counts. At a speed of 60 kilometers per hour, you drive a
kilometer per minute and thus 50 meters to an unlit pedestrian in three
seconds. Little time to react. In the ninety, which is allowed outside the
village, it is only two seconds.
The experiment showed one more thing.
A reflective
material element at the bottom of the feet is much more helpful than on
a jacket or backpack. This is because the car lights shine approximately at the
height of an adult's knees.
In 2013, according to police
statistics, a total of 134 pedestrians died, including 80 at night. That's why
the police are promoting reflective tapes. The tape is not an inexpensive
matter (we bought it in a branded sports shop for 199 crowns), but the police
sometimes distribute the tapes during preventive events.
"I remember that, in cooperation
with the health insurance company of the Ministry of the Interior, we equipped
several thousand tapes in the field and distributed them to people," said
the Police Presidium spokesman Jozef Bocán. It is not excluded that similar
action will be repeated.
