Laser axle sensors deliver accurate traffic data

The 1229 Iowa Department of Transportation in the US has selected Peek's AxleLight non-intrusive laser axle sensors installed in a permanent site along Interstate 35/80 in Des Moines.

This is the first time that the AxleLight sensors, normally designed as a temporary study tool, have been installed in permanent roadside cabinets.

AxleLight sensors shoot a beam of non-visible laser light across the roadway, just a few centimetres above the pavement. Using these sensors, and the ADR family of Automatic Data Recorders from Peek Traffic, state and municipal governments can count, classify, and analyse traffic flow.

Peek worked with the Iowa DOT to certify that the AxleLight units would satisfy the state's high accuracy requirements in the permanent installation environment. The department is using the AxleLight, along with the solar panels and wind turbines that are powering the units, as both a solid and safe source of valuable traffic flow data, and also as an example of 'green' technology at work.

  • The Path to Climate-Neutral Road Construction
    October 1, 2023
    Machine manufacturers and construction companies around the globe are currently searching for ways to achieve the goal of climate-neutral construction. The challenge here is to successively reduce emissions of CO2 and other harmful gases (summarized to CO2 equivalents: CO2e) around the world to zero over the coming decades. In the road construction sector, this transformation is inextricably linked to the improvement and further development of production and working processes. In the future, machines and construction materials will also be assessed based on the climate-harmful emissions arising from their production and use. However, the focus should not be on individual machines, but on the entire process leading up to the finished product – a road. Ultimately, the decisive factor is the emissions generated per kilometer of newly built or rehabilitated road – the “CO2e per work done”.
