the speed limit of the calculation is used in finland, too, resort to improve safety, for example in places where there's been an accident.
Now the american Penn State university according to researchers, too much down-drawn restrictions not improve either safety, but even to increase the risk of accidents.
the Research was conducted in the USA state of Montana.
we found that death or serious injuries lead to accidents increased, when the speed limit was lowered to 16 km/h or more, says assistant professor Vikas-Gayassa.
– If the speed limit is lowered too much, the drivers are no longer paying attention.
Everyone on the road is according to the researchers own deferred the safest speed, that people mostly follow.
according to him, the recommendation limit can be calculated to a maximum of 8 km/h, if you want to increase road safety.
But when we go on social or political pressure to decrease this speed more, so the benefit disappears.
respect for the Law disappears also too low speeds. Low restrictions in areas driven clearly more of a big speeding ticket, than a little higher speed areas.
for Example, 80 km/h speed limit areas was driven two times less speeding than this limit at lower restrictions.
