Fibre Optic Traffic Loop

Fibre optic Traffic Loop solutions

During the implementation of detection loops in the asphalt, in the eyes of Infra Sensor Solutions the operational procedure is very illogical.

When the top layer of the asphalt is installed the asphalt is rolled firmly to a nice and compact structure. After a period of cooling down this firm structure is destroyed by making grooves in the top layer to install the detection loops. After installation of the detection loops the grooves are filled up with hot or cold bitumen.

The result of this configuration is that during firm maintenance all detection loops are to be replaced. Through the years you need regular maintenance to keep the detection loops operational. Consider the polishing of the loops because of the arising of rutting profile, erode the edge structure of the asphalt, to come off of the detection loops during periods of frost, et cetera.

Infra Sensor Solutions designed a fibre optic detection loop. This detection loop is installed in the under layer of the asphalt and will remain operational during and after firm maintenance with top layer asphalt replacement. Another advantage of the properties of fibre optic is the immunity of electro magnetic interference, this means that this solution functions optimally in all circumstances. By using this clever build solution the asphalt top layer stays intact and the time between maintenance is longer. The end result is a longer availability if the lanes.

 

The ‘FIBER LOOP’ solution of Infra Sensor Solutions

FBG | Fiber Bragg Grating

Our ‘fiber loop’ DIG_ISS_LOOP (Digital brochure) solution is based on the innovative Fibre Bragg Grating (FBG) technology. This technology introduces several unique advantages such as the high reliability, accuracy and the long life cycle.

The high sensitivity of this technology enables to install the detection loops deep under the top layer of the asphalt, without loosing any functionality.
