Should speed limits be increased or decreased to reduce the number of accidents?

A thorny issue in the world, should we decrease or increase the speed limits to hope to see fewer accidents, but especially less injured people and deaths on the roads?

Severity

On the one hand, it would seem logical that lower the speed is, fewer the number of accidents will be, but especially the accidents are less likely to be fatal for vehicle occupants or pedestrians.

The attention

In reality, a lower speed can entertain the driver. He sees the scenery more, he is less focused on the road. He can also touch his smartphone, or the buttons of the passenger compartment of the vehicle.

Economy

On the other hand, lowering the speed means reducing the time at work or the time of sleep. But also the number of transport of products and services, so ultimately restrict the economy of a country.

But also, if we do not reduce speed, there is the cost of health services for the large number of people injured and the loss of profits for companies because of their absence from work. Similarly, for families of victims who will be traumatized for a long time, if not for life.

Statistics

According to the following statistics, by eliminating small countries, if the speed outside agglomeration is set at 80 km / h, we have on average:

For all countries: 3162 accidents, 1528 injuries and 130 deaths per million,
For all developed countries: 1509 accidents, 1823 injuries and 53 deaths per million,
For all developing countries: 201 accidents, 253 injuries and 219 deaths per million,
For all countries in Eastern Europe: 4110 accidents, 2958 injuries and 120 deaths per million,

If the speed outside agglomeration is fixed at 90 km / h, we have on average:

For all countries: 1868 accidents, 2127 wounded and 126 deaths per million,
For all developed countries: 1872 accidents, 2463 injuries and 84 deaths per million,
For all developing countries: 2541 accidents, 1535 injuries and 241 deaths per million,
For all countries in Eastern Europe: 1607 accidents, 2069 injuries and 93 deaths per million,

If the speed outside agglomeration is fixed at 100 km / h, we have on average:

For all countries: 3503 accidents, 2731 injuries and 137 deaths per million,
For all developed countries: 3015 accidents, 3809 injuries and 56 deaths per million,
For all developing countries: 4235 accidents, 1114 injuries and 222 deaths per million,
For all countries in Eastern Europe: speed limits below 100 km / h.

Out-of-town roads are the type of road with the highest number of deaths and traffic accidents.

Developed nations

Looking at these figures, for developed countries, it is clear that higher the speed limit is, the more accidents and injuries occur. For the number of deaths, this is also true between 80 and 90 km / h.

Other

For all countries, this is true for the number of wounded. For developing countries, this is generally true. For the countries of Eastern Europe, the opposite is happening. In these countries, alcohol is an important factor.
