Flowell, a dynamic lighted signage

The dynamic LED traffic signal system, Flowell, has been developed by the company Colas. It is being tested in real life since March 2020, on a very dense intersection in the Ile de Nantes sector. Flowell shows the trajectory and approach of the priority 5 busway line on the ground and alerts other users of the public space. 

• Improved safety for users of the area (no accidents involving injuries or property;
• Improved compliance with traffic lights, except for cyclists;
• Good understanding and acceptability of the Flowell device
• Decongestion of the intersection to facilitate the passage of buses: reduction in the number of emergency braking and complete blocking of buses; good understanding by motorists that the dynamic light system indicates the imminent crossing of a bus.
• Improvement in drivers’ working conditions: nearly two-thirds of drivers report better compliance with traffic lights.
