In Moscow, at the intersection of the understudy Avenue of Peace and Agricultural Street, a traffic light was installed. And then there were protracted traffic jams that were not there before. The situation returned to normal when the traffic light … turned off. The conclusion is obvious: miscalculated! I wonder who decided that a traffic light is needed at this intersection? But its installation costs a lot of money. And still need to fork out for dismantling.
The main difference between a modern traffic light and its predecessors is the presence of electronic brains, thanks to which half of the capital's traffic lights can be controlled from a situational center. Communication is via wires (usually fiber optic) and a radio channel. Provides protection from hackers.

Who is guilty?
In Moscow, traffic lights are monitored by the data center (Center for Traffic Management), which analyzes the situation: the regularity and extent of traffic jams, the number and severity of accidents, the density of foot traffic. The data is also provided by the district commissions for road safety. Any metropolitan traffic light passes a multilevel approval, including coordination with the traffic police.
New traffic light at the intersection of Boulevard Ring and Petrovka: reduced dimensions, camera eye, graphic display of signal duration. New traffic light at the intersection of Boulevard Ring and Petrovka: reduced dimensions, camera eye, graphic display of signal duration.
They say that such smart cabinets of traffic lights will appear on the streets after a while. At whose expense are we walking? They say that such smart cabinets of traffic lights will appear on the streets after a while. At whose expense are we walking?
When asked about the “problematic” traffic light, they told me at the data center that it appeared during the reconstruction of the Yaroslavl highway, where it was supposed to change the traffic pattern. Local residents asked to set a traffic light for pedestrians. The scheme was not changed, the traffic light was turned off, the inhabitants were silent. The traffic light did not arrive at the balance of the data center. Customer - Moscow Construction Department. There, they say, and ask.
However, it is already clear that by the standards of the capital's Center for Traffic Management, one traffic light is nothing. Now in Moscow there are about 40 thousand traffic lights combined in 2390 traffic lights. One more, one less … Money is not hard, but from the pockets of taxpayers.
How much is a traffic light?
The cost of the simplest three-section traffic light of type T1 starts at 15, 000 rubles. This is a basic minimum, the final price depends on the type and number of traffic lights at the intersection, as well as on the difficulty of installation. For example, a traffic light on Yablochkova Street cost 1 214 140 rubles, and at the intersection of Trubetskaya Street with Usacheva Street - 5 290 390 rubles. Several million rubles - the average Moscow price for turnkey intersection equipment; it includes the installation of not only traffic lights, but also road signs, signs, fences, as well as marking.
All metropolitan traffic lights are of domestic production (including Moscow), however, imported components can be used in them. All metropolitan traffic lights are of domestic production (including Moscow), however, imported components can be used in them. Related Materials
Directions to yellow: is it possible or not? In the regions, as a rule, cheaper - primarily because of the cost of work. For example, in the city of Kasli in the Chelyabinsk region in 2013, a traffic light object (eight traffic lights) cost 270, 000 rubles. In the Tambov region 24 traffic lights were purchased for 334, 000 rubles. That is, cheaper than 14 thousand apiece - as they cost at a wholesale discount.
But putting traffic lights is half the battle, they also need to be maintained. Every ten days, everyone checks the performance, wear and damage, clean the lenses. Scheduled work is provided - from test operations to cleaning contacts and measuring insulation resistance. You need to pay a salary to maintenance personnel, maintain transport, buy consumables and spare parts. All this is also a lot of money.
They can see everything from above
Traffic lights are not limited to maintenance. I visited the situation center, where they coordinate the work of metropolitan traffic lights. Two dozen large screens display images from surveillance cameras. If there are difficulties in movement, the operators change the mode of operation of traffic lights, choosing the most suitable of the established five or seven algorithms. A traffic jam is going on in one of the streets - the operator changes the mode, the “tail” begins to melt before our eyes. Spectacularly!
Prospect Mira: “lying” traffic lights not only on the ground, but also in the air. But why is the red segment on the right? I had to turn to the data center with a complaint. Already corrected.

But such a switching of modes does not always help. According to my observations, congestion occurs with surprising constancy in the same places, and it is impossible to notice the change in the algorithm of the traffic lights from the traffic jam. Traffic lights simply work out the program, and do not monitor the situation - whether the vehicle is moving or not. Often, traffic cops take control of complex situations much more effectively. But are these situational centers needed then? Is it worth it to build and equip premises for them, buy expensive equipment, and keep employees?
Spectacularly. Is it effective?
Moscow public transport will switch to the “green wave” in 2018 Last fall, the first “lying” traffic light appeared on Mira metropolitan avenue - glass bricks were mounted in the asphalt with backlight that duplicates the signals of an ordinary traffic light. Similar “lying” traffic lights are already operating in St. Petersburg and Chelyabinsk. Luminous stripes - anti-vandal, withstand the weight of heavy equipment and blows up to ten kilojoules - at least hit with a sledgehammer. And they look beautiful. But what is the use of them?
I jokingly threw the idea to the initiators: this is a traffic light for those who walk the streets with their nose in their smartphone.
Fiction: my version has become official! And, apparently, they allocated an additional budget for this idea, because the design was finalized.
The letters “Stop” and “Go” were added to the luminous stripes so that the signals on the sidewalk would not confuse the drivers. The luminous stripes themselves were made wider and brighter, so that they could be seen in the sun, and even under a layer of dirt or snow.
Traffic lights for cyclists are also found in the center of Moscow. It remains to make the "pedal" implicitly comply with the requirements of the electronic traffic controller.

Know in person: how cameras record video violations According to the company "Ira", which specializes in the lighting of cities, the renovation of the "traffic light underfoot" was carried out at the request of local residents.
And here is the statistics: for the year of operation of a smart traffic light on a dangerous section of the road, not a single accident happened with a fatal outcome. How many of them were before - they do not say.
To improve traffic safety, according to innovators, a luminous cord running along the L-shaped traffic light support should also. This can be seen, for example, at the very beginning of Leningradsky Prospekt. However, when we went to photograph it for an article, half of the LEDs in it no longer burned. They didn’t spend budget money on know-how: one of the data center contractors purchased and installed the cord. And the latest news on this subject: the experiment was found to be successful; by the end of the year, 54 traffic lights with supports that change color will be installed in the capital. This is already on budgetary funds.
Last fall at the intersection of Boulevard Ring and Petrovka, compact traffic lights were installed with integrated video cameras and motion sensors. In addition to performing their main function, they still monitor the situation at the intersection and transmit information to the control center. Is it innovative? Of course! And how was it possible thanks to this know-how to raise the level of security and improve traffic management? Officials are still silent about this.
If you see an inoperative traffic light in Moscow, do not be too lazy to call the short number 3210. This will help to fix the malfunction faster. Such "emergency" numbers are also in other cities - usually they can be found at the traffic lights themselves.
FIVE AND A CENTURY AT THE SERVICE
The first Moscow traffic lights were a little like modern ones and looked like a clock. Instead of electronic brains, they had a mechanical time switch. The first Moscow traffic lights were a little like modern ones and looked like a clock. Instead of electronic brains, they had a mechanical time switch.
The first traffic light appeared on December 10, 1868 in London. Designer John Peak Knight took the railroad semaphore as a role model. On the pole he mounted two lifting flags stopping the movement, and on the top - a gas lamp for night work, with red and green signals. True, the traffic light worked only a month and exploded, injuring the policeman who controlled it.
Nevertheless, the device has proved its effectiveness by at least a little streamlining chaotic street traffic.
In 1910, Ernst Sirrin (Chicago, USA) patented an automatic traffic light control system. Two years later, Leicester Wire (Salt Lake City, USA) developed a traffic light with two round electrical signals. And already in 1914 an American traffic light company appeared, which put four electric traffic lights designed by James Hog at the intersection in Cleveland with red and green lenses and a sound signal. They were controlled by a policeman from a booth.
Three-color traffic lights were also first made in the USA - in Detroit and New York, in 1920. Their authors were William Potts and John F. Harris.
The first traffic lights appeared in Russia in 1930: January 15 - in Leningrad, at the intersection of the avenues of October 25 and Volodarsky (Nevsky and Liteiny), and December 30 - in Moscow, at the corner of Petrovka and the Kuznetsk Bridge.
