An almost invisible detail on the road reveals when a vehicle is being monitored. How to find it.
Traffic control cameras are not only responsible for registering infractions: behind them there is a more complex system of sensors that allow measuring and ordering circulation in Argentine cities and routes. Its main objective is to verify respect for speed limits, although they also collaborate in the management of daily traffic.
One of the most used mechanisms are calls inductive spiralswhich consist of cables installed under the pavement in the form of squares. When they are placed from two, They allow to calculate the speed of a vehicle by measuring the time it takes to move from one to another. This system is the most common in the country’s fixed radars and, at the same time, it serves to account for the flow of cars.
The trick to identify speed radars on the route
“With a single loop you can count the number of vehicles that circulate; on the other hand, with two the speed is obtained,” he explained Martín Viale, professor of intelligent transport systems at the UBA, In dialogue with LN. From there a key fact arises: if a driver observes two square brands in the asphalt, he is probably in front of an controlled area.
In addition to this method, there are radars Dopplerwhich work by waves and are usually used in mobile or rotary controls, without the need for turns.

Beyond technology, specialists highlight the importance of these systems in road safety. According to recent studies, cameras contribute to reducing between 20 and 37% the accidents, and in the city of Buenos Aires it was found that speeding was present in more than half of fatal accidents.
On the other hand, the turns play a central role in urban planning. They allow to identify congestion peaks, adjust traffic lights or even prioritize ambulance passage in sensitive areas. Thus, these tools not only sanction, but they help order mobility and improve the safety of all public road users.
