<strong>Sensys</strong> <strong>Stud</strong> <strong>Trial</strong><br />
6. Cost Comparison and Compatibility<br />
6.1 Cost Comparison Installation of Detectors<br />
Being an active sensor with electronic components each individual stud costs considerably<br />
more than a loop to supply and install, however savings can be made on traffic control.<br />
3 Lanes<br />
The first example shows a typical installation of a 3 lane site. Due to restriction in working no<br />
closer than 1m from cones, a full motorway closure is required to cut the loops. In this case the<br />
cost of supply and installation of <strong>Sensys</strong> studs is actually less that installing loops.<br />
For 1 Site, 3 lanes<br />

4 Lanes<br />
This example shows a typical installation of a 4 lane site. Here a motorway lane closure can be<br />
used and the safety distances maintained. This shows that it is cheaper to install loops. It<br />
should be noted however that cutting these 4 loops would take all night, however installing the<br />
studs would take just 2 hours allowing another site to be done in the same night.<br />
