Poland is a pioneer in the field of new road signs that combine a set of sensors to monitor road traffic and conditions to warn drivers of the dangers on the road ahead. Researchers are developing “smart” highway signs to track traffic volumes and alert drivers in real time to potential hazards as part. From a national project called INZNAK.

The signs also measure weather conditions and use several forms of radar, including sound vector sensors.AVS), Used traditionally for underwater applications.

وتقرأ AVS The reflected sound waves are calculated and traffic flows on a specific stretch of the highway, which can then be transmitted to drivers to warn of congestion.

According to the British “Daily Mail” website, smart road signs also come with a built-in Doppler radar – a specialized radar technology that relies on the Doppler effect. Doppler radars are already used along roads to read how fast cars are moving and tell drivers to slow down if they are traveling over the limit. Speed ​​limit, as well as police rifles.

In smart road signs, Doppler radar measures the speed of objects such as cars or precipitation drops hitting roads.

When introduced, a whole network of signage will also communicate via vehicle technology to everything (V2X) – it is a form of a network Wi-Fi Designed for the fast-moving things of smartphones and cars that support technology Bluetooth Talk to each other.

The entire project is funded by the Polish National Research and Development Center, the country’s public agency for scientific innovation.

Describes the principal investigator of the project Andrzej Czyzewski Of the Gdansk University of Technology in Poland, his work at the 179th meeting of the American Acoustic Society, which takes place from December 7-10.

He said Czyzewski: “We can calibrate the sound bus sensor [AVS] So that it can be used to measure the volume of highway traffic and count vehicles by analyzing the noise that they emit during their passage, and when it is successfully implemented, the devices that we have developed will communicate with each other in a technique V2X It will actively interact with the traffic situation, and suggest the drivers the appropriate speed for the situation. “

The technology was due to be rolled out earlier this year, but the epidemic has slowed production, according to Czyzewski.

Road signs will continue INZNAK With each other in relation to data such as weather conditions, road surface conditions, traffic volume, average vehicle speed, and detected road events, such as accidents or congestion.

Each marker will run an algorithm to process that data and calculate the current condition of a designated section of road and driving conditions.
