Its commitment to environmental responsibility and economic development consolidates it as a benchmark in the sector, prioritizing modern practices and solutions focused on safety in operations.
Problems
Truck traffic on access roads, shared with other vehicles, posed a significant collision risk because, due to the trucks' considerable weight, it was difficult and dangerous for them to brake and overcome inertia before entering the main road.
Solution
We use Wave RFID tags on trucks and readers on roads where other vehicles travel. When a truck is identified by the Wave reader, we inform the traffic light system, which prioritizes traffic, preventing collisions.
Advantages
Reduces the risk of trucks colliding with other vehicles traveling on shared roads. It also reduces brake wear and, consequently, fuel consumption and speeds up the logistics process.
Benefits
It prevents material and human losses.
Target Audience
Logistics and Traffic.
Arcelor Mittal Tubarão - Traffic system control: much more safety.
The logistics operation faced a recurring problem: trucks had poor visibility of smaller vehicles very close by, which increased the risk of collisions and even crushing, especially on shared roads. To mitigate this risk, an RFID-based solution was implemented using readers installed near busy intersections and access points. The trucks began using Tags applied to the windshield, which are detected by the L-A210 readers whenever they approach a critical point. Upon receiving the Tag signal, the reader transmits the ID to the controller via RS-485/232 communication, where the logic identifies the correct direction of the truck using three readers to avoid erroneous readings. Then, the controller activates the modules responsible for automatically changing the state of the traffic lights: when there are no trucks nearby, the signals remain flashing yellow, forcing smaller vehicles to slow down and check if they can proceed; When a truck approaches, the system turns on the green light so it can pass without braking and activates the red light for other vehicles. After the passage is confirmed by the second reader, the system returns the traffic light to the standard flashing mode. With this fully automated process, the need for personnel to direct traffic is eliminated, and the risk of accidents is significantly reduced, protecting lives and preventing material damage by making traffic flow safer and more predictable.
