Sensys Stud Trial
3 Lanes, 2 Sites
This example shows a typical installation of two 3 lane sites on the same side of the motorway
in close proximity. Due to restriction in working no closer than 1m from cones, a full motorway
closure is required to cut the loops
For 2 Site, 3 lanes

Summary
As can be seen from the examples above the relative costs depend heavily on the situation.
Where there is space to close lanes to cut loops these provide a cheaper solution, whereas if
the motorway has need to be closed due to space restrictions then studs become a more
closely priced or even cheaper option.
