Smart traffic monitoring

Innovative technology for detecting passing vehicles

For a long lifetime of roads, it is necessary to have prompt and intensive monitoring in place to protect and maintain these infrastructures. Our unique system employs a specially designed strain detector that is suited for installation in the asphalt layers or under the roads. This detector flexes due to strain along any point of its length. The information obtained enables efficient planning of maintenance.

Request information

The detectors are installed in the different groove depths of asphalt to obtain information on optimum system installation for different road scenarios. The various road conditions are tested to determine the best installation method, with respect to using the right materials, to achieve the highest and most stable performance possible. Afterwards, installations either into cold reactive asphalt filled grooves or hot asphalt withstanding grooves are performed.

The passing vehicles are successfully and clearly detected enabling you to apply the SigProc Data Processing software to automate the traffic monitoring. Traffic parameters, such as classification and vehicle speed, are calculated by SigProc’s Dynamic Threshold algorithms thus filtering impact of environmental noise and temperature.

Moreover, passing vehicle footprints, with different axle weight impacts, are observed and provide promising signs for new application developments in Weight in Motion (WIM) which combine benefits of the fiber optic approach, installation and maintenance requirements, and costs.

Embedded monitoring

Our system is designed to be embedded into the upper asphalt layer of the road during, ideally, the re/construction phase.

Balanced response

Our system uses a unique mechanical design that provides excellent sensitivity along its entire length to ensure a balanced response to a whole traffic lane.

Measuring various traffic parameters

Compared to magnetic loops our system also enables measuring the weight of passing vehicles. When used together with magnetic loops, the vehicle’s metal chassis can be clearly identified.

No maintenance costs

Usually there is at least 10 cm of asphalt above the detector position. Thanks to this, there is no visible mark on the surface under which the sensor is installed. Moreover, it will not be damaged when milling the surface layer of asphalt. It is maintenance-free and long-lasting.

Highly resistant

One of the biggest benefits is that the system withstands the repeated laying of hot asphalt layers and intensive machine rolling.

Alternative to conventional systems

Our system can easily replace conventional systems installed in the top layer of asphalt which may be prone to breakage and difficult to repair, and which may require replacement during periodic maintenance.

Insensitivity to environmental induced noise

Compared to magnetic loops, our system is inherently insensitive to environmental noise and is therefore suitable for measurements that could be distorted by ambient sound.

Fiber Bragg Grating (FBG) technology

FBG technology brings many advantages over the conventional sensing methods, such as immunity to EMI/RFI, high precision, durability, quasi-distribution and absolute measurement, compact size, and reduced cable requirement.

Special design

Special detector, designed with a minimal footprint, enables direct and fast installation in different layers of the asphalt infrastructure or under the roads.

Simple installation process

The detectors can be installed into a small groove in asphalt cut by a standard cutting blade. There is no need to mill large areas or deal with power supply cables.

100% passive solution

The detector construction is fully passive without the need for power. Therefore it easily monitors places without access to power and hazardous or inaccessible areas.

Customized size

The detector’s sensitive length can be customized to match the road or lane width with a different number of detection points.

Multifunctional measuring platform

Several sensors with different functions can be connected in series on a single fiber without signals being confused and with the necessary cable length being considerably smaller. The comprehensive monitoring system can be configured this way.

Connectivity

The detector can be used alone or incorporated into a larger detection network to minimize the cabling costs.
