Redirecting traffic flow


Traffic jam is a well-known irritation factor for many people. It is often a consequence of traffic lane closure or blocked highway sections caused by collisions or road works. Traffic jam creates serious disadvantages in terms of increased air-pollution, wasted time, stressed road users, economic costs and even more traffic accidents.


To reduce traffic congestion and overcome these problems, SPIE invented the VEVA. The movable motorway barrier can be used to create flexible traffic lanes so that accumulating vehicles can be easily rerouted. By a one button push on site or from the Traffic Management Center (TMC) the VEVA is activated and available road space is used efficiently. Consequently, a quick redirection of traffic flow and lane release is ensured.

Road works and accidents on motorways require motorway management authorities to have an effective and efficient plan of approach. If highway traffic lanes or tunnel tubes need to be sealed off, the safety of road users, traffic directors and emergency services must be guaranteed.

SPIE provides innovative traffic management solutions, CADO and VEVA, that provide added safety for road users and maintenance staff, and help ensure the consistency of traffic flows in a swift way.
