From what speed are the outrages fatal

Not surprisingly, a difference of just 20 kilometers can save the lives of the most vulnerable actors on the road. Aware of this,  the Civil Guard warns: at more than 64 km / h, in a hit, 85% of pedestrians die.

The data leaves no room for doubt. According to the World Health Organization (WHO), 50% of deaths recorded on the different roads have pedestrians, cyclists and motorcyclists as protagonists. And speeding is usually the common denominator in all these claims. Keep in mind that if we travel  at a speed between 30 and 50 km / h, the risk of death is multiplied by five,  according to a report by the International Transport Forum (FIT) for the Organization for Cooperation and Development (OECD).

Speeding: common factor

Respecting  speed limits  is therefore key. And here physics is the answer: the faster the kinetic energy released increases the square of the speed. To this we must add that time and maneuverability are also less: it takes us a second to react to an unforeseen event and choose the appropriate response. A time that disappears when we circulate at 30 kilometers per hour.

We see how speed is decisive in  30% of fatal accidents. Failure to respect limits increases the risk of accidents and the probability of causing serious injury or death. How much? These are the percentages that the General Traffic Directorate manages:

30 km / h30%65%5%
40 km / h4%fifty%Four. Five%
64 km / hfifteen%85%

Slow down: a possible solution?

The  limitation  is how important that management has at its disposal the  DGT . When these really influence, they have an impact on the safety of the driver and other actors on the road.

Rune Elvik, a specialist in road safety, has shown that reducing the limits by 10 km / h implies a 2.5 km / h decrease in average speed. A good example of this is the United Kingdom, where the maximum speed for residential areas has been set at 30 km / h. As a result, there are 67% fewer collisions with children and cyclists. The  Nilsson model  reinforces this theory: if we lower our speed by 1 km / h, fatal accidents will decrease by 4%. Therefore, restricting the limits at 10 km / h would imply 10% less mortality.
