Brake brakes

"The Moscow authorities are going to reduce the limit on the speed during peak hours from 60 km / h to 40 km / h." Such headlines are replete with news feed.
WELL WHAT FOR FOODS ??? A lot of research shows that you need to raise the minimum speed on the contrary to reduce traffic jams! Not just as in normal countries make roads without traffic lights. Why the hell are they trying to introduce this nonsense here ?? Now traffic jams will appear where they have not yet been ...
In short, Habrachelovek, say "NO!" Car, sit on the bike!

UPD OK. Let's count. Here we have a section of the road. Let's say after a traffic jam. Suppose absolutely empty. Suppose a width of one lane. How many cars can go to this site in an hour? Let the length of the machine n meters, and the distance between the machines m meters. Maximum travel speed - V.
Then the maximum number of cars that will enter this area X = V*t/(m+n) .
In short, the road’s carrying capacity is directly proportional to the speed (maximum, average) of traffic on it. By reducing the maximum speed, we reduce the throughput capacity of the roads. The result - in traffic you will stay even longer.

UPD2 Here is another commentary on math based on this article .
