Totems Traffic Lights

The Totems system was designed to provide a preventive warning to the pedestrian, who is sometimes distracted and doesn't notice the traffic light change. While there are pedestrian indicators, these are not as effective, as is a message displayed on a screen

In addition, the idea is that this sign not only serves to indicate a traffic light change but to alert the community when a fact of common interest occurs.
The system is modular, so each subsystem performs a certain function and is easy to replace if it fails.
