<strong>Sensys</strong> <strong>Stud</strong> <strong>Trial</strong><br />
3.6 Traffic Control<br />
For a 3 (or more) lane carriageway as the time taken to install each stud is less than 15<br />
minutes, a semi static closure can be used to close 2 lanes allowing 4 studs to be installed.<br />
This is considerably less time consuming than setting out a Standard 2 lane closure as is<br />
required to cut loops; these take longer than an hour to cut.<br />

If multiple sites are being installed then this closure can easily be moved along the motorway<br />
to the next site.<br />
For 2 lane carriageways it is considerably easier to install <strong>Sensys</strong> studs rather than inductive<br />
loops. When installing loops which must be installed 700mm from the edgeline, the whole<br />
carriageway must be closed so that the 1m safety zone can be maintained. This causes<br />
considerable inconvenience to road users as they have to follow detour routes. It is also<br />
expensive when compared to a semi-static closure, approximately $6,000 for the full closure<br />
compared to $600 for semi-static.<br />
When installing studs, as they are placed in the centre of the lane 1.5m from the edgeline, a<br />
single lane semi-static can be used. Similarly to a 2 lane closure, if multiple sites are being<br />
installed then this closure can then be easily moved along the motorway to the next site.<br />
