In most developed countries, the progress of highways is so much ahead of domestic progress that, once in some countries, Russian tourists are in a state of shock. One such shocking device is the smart traffic light, which is not only very practical but also inexpensive.
These are not just single fashionable devices designed to systematize traffic. This is a real intelligent system that controls traffic in the entire city as a whole. It is to this system that traffic lights are connected as well. In addition, it may also include barriers and other traffic controls. Such intelligent systems have uninterruptible power supplies, which are necessary so that a transport collapse does not occur in the city, because in case of a power outage, all devices will fail at once.
How do they work?
A webcam is connected to each traffic light. Video cameras transmit the most up-to-date information online about the flux density to all neighboring traffic lights, which are connected in series. The technology that adjusts the time between traffic light changes is based on the latest data received from the neighboring nodes of the intelligent system.
This system makes it possible to pass cars with a minimum delay, while holding the cars if there is a traffic jam on the next street. The system instantly reacts to situations such as traffic accidents, car breakdowns on the road, repair work or vehicle parking along the side of the road to block traffic in time. Delays at such traffic lights are negligible, but in just one minute, such an intelligent device can completely regulate traffic at a difficult intersection or in a situation with an accident.
Benefits of smart traffic lights
The benefits of such smart devices are obvious to everyone. On domestic roads, in case of emergency, traffic controllers go out on the road to help drivers go through a difficult section. But this is not always an effective method, because the traffic controller does not know about the constantly changing traffic on the neighboring streets. And the intelligent system itself calculates the required delay time for car traffic, receiving the latest data on the state of the neighboring streets.
In addition, the installation of such traffic lights will make it possible to completely abolish this division. After all, there will be no point in traffic controllers. They will be replaced by fully automated systems that do not fail and work in all conditions, regardless of the circumstances on the road.
