Peak/rush hour (Reverse flow)


During rush hours in the morning and early evening, a problem many motorways cope with is that they can hardly bear the heavy traffic. The tidal flow of traffic creates congestion on the highway and disadvantages of traffic jam arise subsequently. Continue construction of additional traffic lanes is simply not a solution since eventually one will run out of space and funds.


Instead, the VEVA provides a more efficient and cost saving, preventive road solution to reduce traffic congestion on the motorway. By moving the VEVA crash rated movable highway barrier, redundant traffic lanes can be utilized as an extra lane for the contra traffic flow. In fact reversible lanes are created. When closed, the VEVA blocks access to the reverse lane. This system prevents ghost-riding while maximizing the highway capacity.

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.
