Why on roads there are traffic jams?

From - for accidents - you will tell. It appears - not only from - for them. The scientific explanation of a phenomenon which I often observe on roads of Moscow is received. Especially on the Moscow ring highway. It though has 6 - 8 rows in each party, but in case of a jam there is no place to get to - at the left and on the right concrete and metal protections, and congresses from it at distance of several kilometers from each other.

Therefore on MKAD often there are traffic jams. At first the movement is slowed down, then stops at all. Sometimes for a long time. Then suddenly the movement is resumed, cars gradually accelerate, but on the road accident traces are not visible. In what there was a delay reason?

The group of the European scientists constructed mathematical model of these abnormal jams and explained a secret of their emergence. Drivers in a stream go unevenly - approaching the car going ahead, slightly moving away from it. If someone stood gaping and approached too close, then presses a brake. Calculations showed that if speed is reduced below a certain critical mark, the following car will be forced to slow down stronger, following it - is even stronger and so on. As a result, in several hundred meters from a point in which there was such event the steam of cars stops almost completely. At the same time to the drivers who got to a jam it will be absolutely not clear from where it, actually, undertook.

The received model claims that the similar scenario of formation of traffic jams is very typical for the brisk highways having loading more than 15 cars on strip kilometer. The created traffic jams constantly move in the direction opposite to the movement of cars, forming so-called return waves. Even the one and only stood gaping driver can exert huge impact on all transport stream and lead to mass delays.

From here a conclusion - the is more skilled drivers in the weight, the less will be jams. If you go in a dense steam of cars, it is necessary to brake as little as possible and as much as possible smoothly. You watch behavior of other cars and try to predict development of the situation. I usually try even to smooth rate of the movement if ahead the going driver twitches. However, even if slightly - slightly you will lag behind, often is in the next row clever man which is right there reconstructed on free place.

Our authorities try to solve problems of traffic jams construction of new roads and expansion of old. Introduce various restrictions for types of cars and time of day. And the level of training of drivers is not connected with traffic jams. Only indirectly through accidents. And it turns out that even without accidents inexperienced drivers cause traffic jams. But even more impudent - provoke both accidents, and traffic jams.

Let`s respect each other on roads and to go smoothly. It will keep not only nerves, but also will reduce wear of the car, fuel consumption and accident rate. And traffic jams as the science showed, will become less. What will lead to further preservation of nerves, cars and gasoline.

Pleasant, safe and economic to you driving!
