Remote Communication for Traffic Lights

Improve urban efficiency with Remote Communication for Traffic Lights: real-time monitoring and control for traffic optimization.

Challenge

Modernize network infrastructure and enable remote communication with traffic lights at various points in Rio de Janeiro.

Solution

Cellular Routers and Bridgemanager System for managing connections with the customer's supervisor.

Our client had a worn-out and obsolete RS485 serial network infrastructure, with high maintenance costs. They needed a robust and reliable remote communication solution to control hundreds of traffic lights in specific areas of Rio de Janeiro. The application was critical because, as in any large metropolis, the city could descend into chaos if communication with the controllers failed.

Above-Net provided the solution using rugged industrial cellular routers, combined with the Bridgemanager system, which monitors and manages connections. This solution enabled transparent Internet/VPN communication between the CCO and the traffic light controllers, providing the client with valuable data on connection status, data traffic, and signal strength.

The products and systems involved in the solution are industrial and prepared for critical operations and large volumes of connections:

Robustel R3000-L3P – Dual-SIM cellular router with 1 Serial port and 1 Ethernet port;
M1000XP – Cellular Modem with Serial Port;
Bridgemanager – A cellular connection management and monitoring system. Hosted in a redundant data center, it ensures reliability and robustness for large connection volumes. In addition to enabling a transparent link between the supervisor and field equipment, it generates data and information on signal strength, location, connection status, and more.

This solution has been in operation for some time and has been replicated by the client in other cities due to its reliability, high availability and excellent cost-benefit.
