Continuing the analogy with the car, I note - there are also passive and active safety devices here: the former are designed to prevent an emergency, and the latter are designed to mitigate its consequences.
Observing motorists must have noticed how the traffic conditions vary depending on the markings. It is worth moving out of the dirty asphalt in the spring with the erased markings on the “freshly painted” section, as the rows of cars become slimmer, and their movement is clearly more meaningful. Only the rows are marked, and the ride has become safer!
The length of roads in our country exceeds 900 thousand km, but only a small fraction meets modern requirements. Even in the capital there is work to do. In addition, the coating requires constant care. The marking is already erased by spikes by the middle of winter, anti-icing reagents corrode it. Modern technology allows you to extend the life of the layout even in Russian conditions from three to four months to two years. So much will work polymer tapes.
Putting them on the road is not so difficult: the roll is stacked in a cart like a lawn mower, which is controlled by one person. Unlike traditional paint, marking can be applied immediately after laying the coating, recessed into a fresh layer of asphalt concrete. Such a strip or dotted line is not only much more durable, but also reflects light - thanks to microprisms enclosed in diamond-shaped capsules (on the outside they are covered with a layer of transparent polymer). Even under water in heavy rain, the markings are clearly visible to the driver.
In addition to materials, road builders are also wise over marking drawings. The Japanese and Australians were especially successful, having developed curious non-standard options - for example, “ticks”, applied in the middle of the row. What for? It turns out that when a certain speed is reached, this pattern begins to flicker with such a frequency that it creates the illusion of driving at a speed that is greater than in reality. The driver automatically reduces gas.
Created areas with embossed markings, causing vibration and discomfort when exceeding a certain speed. So far, all these inventions have not found wide application, but the speed bumps once began with an experiment.
It is hard to imagine what would happen if the road signs and signs disappeared from the streets of the cities for at least an hour! Even Russian drivers are gradually getting used to the luminous bulletin board. An extra reminder, for example, about ice will not hurt. And to make the display as economical as possible, they began to use power from solar panels abroad. It only takes 20 minutes of sunlight for them to shine brightly all night. By the way, there are already screens on which the warning text can be changed in just a couple of minutes, for example, by connecting a laptop.
One of the most dangerous violations is a red light crossing the intersection. In the USA, for example, almost a quarter of all accidents occur because of this. Hundreds of people die annually at intersections, and the material damage associated with paying insurance, disability, and treatment bills reaches $ 7 billion.
And here, who considered the consequences of driving on red or “orange”? Overseas have long understood: it is impossible to put a police officer at each traffic light. It is much more effective to record violations with video or cameras. They work in automatic mode. Typically, cameras are installed so that shooting comes from different angles and in different directions. When the green light is on in the traffic light, its camera is inactive. After turning on the red, she, after waiting a split second for the drivers to complete the intersection, turns on - from that moment on, any intruder will get into the frame. Not only that, the first camera transmits a signal to others: they also carefully record the fines. A photo report of the incident will soon be … right, at the police station.
In some states of the police, a photo of the license plate of the intruder is sufficient; according to the laws of others, a portrait of the driver at the wheel must be attached to the case. The cameras are set accordingly. Within a couple of days, an envelope with “compromising evidence” and a fine receipt for an impressive amount will appear in your inbox. It is impossible to avoid responsibility: the cameras work 24 hours seven days a week without a lunch break. All you can do is try to appeal the decision in court if there are counterarguments. Here is such a democracy.
Speed detectors work similarly. The simplest scheme: at a certain distance, two cameras hang connected to a computer. When driving at a permitted speed, the car enters the field of view of the second camera after a certain time. If it is less than the programmed one, the second “eye” will fix the intruder. The rest is a matter of technology.
In Russia, cameras are also slowly being introduced. But, as a rule, they only observe the flows. And if they see the intruder … he still needs to be caught. After all, our laws do not allow fines in absentia. Probably someone is more comfortable …
