Dynamic speed and access regulation leads to more efficient use of motorway capacity.

This expertise is available in the following countries:

Ensuring the safety, control and regulation of motorway traffic

SPIE helps motorway operators optimise traffic management on their infrastructure. SPIE develops cutting-edge technological solutions to ensure smoother, safer and controlled movement of traffic as well as regulating flow.

These solutions include:

  • Mobile barriers: these can be activated automatically at motorway ramps or tunnel entrances to open or close access and direct vehicle flow, depending on incidents or traffic conditions.
  • Variable signs to regulate traffic. Measurement sensors directly connected to the control centre allow for real-time monitoring of traffic flow to regulate traffic and inform road users via information signs of speed restrictions, hold-ups and hazards.

Innovative solutions developed by SPIE help regulate traffic, depending on peak levels of pollution and therefore reduce CO2 emissions into the atmosphere.

SPIE Belgium and SPIE Nederland work together to supply and install four CADO® emergency gates in the Quatre Bras tunnel in Brussels

SPIE Belgium recently won a tender from the AWV to supply and install four 9-metre CADO® emergency gates in the Quatre Bras tunnel on the Brussels ring road (R0) - two on each side of the tunnel. This project, which is due for completion in the first quarter of 2023, will see SPIE Belgium work closely with SPIE Nederland, which will be responsible for manufacturing, supplying and installing the CADOs®.
