<strong>Sensys</strong> <strong>Stud</strong> <strong>Trial</strong><br />
6.2 Cost Comparison Lifetime of Detectors<br />
Due to resealing and general determination of carriageways it is estimated that during the 10<br />
year lifetime of a <strong>Sensys</strong> stud the loops will have to be replaced once. This means that the cost<br />
of loops can be doubled for the same period of time. Therefore the 10 year lifetime costs can be<br />
estimated to be.<br />
3 Lanes<br />
<strong>Sensys</strong> $7,450.02<br />
Loops $16,180.00<br />
4 Lanes<br />
<strong>Sensys</strong> $9,933.36<br />
Loops $10,900.00<br />
3 Lanes, 2 Sites<br />
<strong>Sensys</strong> $14,900.04<br />
Loops $19,480.00<br />
3 Lanes, 4 Sites<br />
<strong>Sensys</strong> $19,866.72<br />
Loops $21,800.00<br />
It should be noted that these costs do not take into account the downtime and inconvenience for<br />
the time that the loops are milled out. As loops cannot be recut the same night as sealing,<br />
typically the loops are down for between 2 to 4 weeks depending on the sealing and line<br />
marking programme.<br />
As the studs send information about their battery life, they will indicate when the battery is<br />
getting to a low level and therefore a planned replacement schedule can be arranged. This will<br />
result in minimal downtime.<br />
Summary<br />
Once the full 10 year lifecycle costs are taken into account, the studs also become a cheaper<br />
option than loops in all situations. It may be that not all loops are required to be replaced in the<br />
10 year cycle, however the pricing on average will be comparable.<br />
