The road sensors 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.
