New radar technologies – installed in different capitals across the country – are ensuring the possibility of monitoring that goes beyond speed levels. Using the so-called doopler effect, linked to the digital loop, radars installed in cities such as Curitiba, São Paulo and Salvador have the advantage of detecting driver behavior.
The use of doppler, together with the use of technologies such as inductive loop and virtual loop (calculation on image) makes it possible to capture information regarding the presence and time of passage of vehicles, allowing statistical information and traffic violations to be recorded, such as, for example , vehicles exceeding the permitted speed, stopping on a pedestrian crossing, traffic lights running red, oncoming traffic and prohibited turns.
The equipment can record everything up to a distance of 100 meters before and following its installation point with great precision, unlike radars that only use sensors on the ground.
As provided for in the Contran (National Traffic Council) resolution, radars must all be approved by Inmetro ordinance and are checked periodically. The system that captures long distances and serves up to four lanes of cars.
“The objective is now not just to measure speed, but also what the vehicle is doing. These are expanded radar surveillance capabilities”, explains urban mobility specialist, Guilherme Araújo.
Among the advantages of the non-intrusive method are the detection of vehicles, it avoids the destruction of the pavement to install sensors, the stoppage of the road for maintenance and unnecessary expenses for public managers
“It is one of the most advanced technologies in the world. The sensors have a range of hundreds of meters and monitor the entire route covered by the vehicle, allowing public agents to monitor and evaluate drivers’ behavior trends, as well as issue fines – if there is disrespect and current legislation”, explains Guilherme Araújo, president of Velsis, mobility solutions company that has the largest number of non-intrusive equipment installed in Brazil. In total, there are more than 1699 monitored tracks and 731 pieces of equipment installed in different cities.
Examples
Em Curitibathe Muralha Digital program, with its 1,900 cameras installed in various parts of the city and integrated into an Operations Center, reduced crime wherever they are located by 40%.
Already in Salvador, After the start of the use of non-intrusive technology, the number of deaths resulting from traffic accidents decreased by 56%, from 247 deaths registered in 2012, to 109, in 2022. During this period there was also a 57% reduction in the number of accidents, rising from 6,827 in 2012 to 2,946 last year.
In São Paulo, the company won the tender to install the equipment, and is just waiting for the date of the tests to be defined.
According to Guilherme Araújo, technologies are currently manufactured using artificial intelligence and integrating data, videos and images to optimize traffic inspection and public safety actions on highways and public roads.
“We are at a time in history when the fusion of technologies to perform complex functions is becoming more frequent, to improve user experience and safety, bringing benefits to society”, concludes Guilherme.
