Schematic representation of a turbine node Schematic representation of a half turbine node
A turbine node is an uneven floor node. Due to the larger arc rays compared to a clover blade, the traffic can be reduced without a change of direction. Compared with a clover blade, a turbine in construction is more expensive. When not all directions are equally important or busy, you can choose between an intermediate solution, the clover turbine.
In Belgium, several turbine nodes have been constructed, including the Brussels ring. In the Netherlands this type has never been fully applied, but half a turbine has been installed in some places. Examples of this are Almere and Empel junction. Also, clover turbines have been installed in various places. Turbine nodes in Belgium
The Zwijnaarde node is designed as a turbine node. The diamond shape that forms this junction has a ground fitting of about 400 by 400 meters. Due to problems with too small arc radiations, the speed has been limited here and there and special anti-slip hardening was applied. Other examples include the junctions Daussolx, Sint-Stevens-Woluwe and Zaventem.
Node Lummen, originally a floating roundabout, was converted into a turbine type between 2007 and 2011.
