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.

    Software mapping of air pollution along transport corridors is an important weapon for improving air quality, argues Arne Berndt*. Although power plants and factories play a large part in increasing air pollution globally, traffic is now the largest single contributor. Commercial vehicles account for a significant share of traffic around the world, with freight volumes projected to grow 40% by 2050. Yet, despite modern vehicles being more environmentally friendly than earlier models, the sheer volume of th

According to ARTBA’s report, 47,052 US bridges are in poor condition, while 18,842 Interstate highway bridges have identifiable repair needs. The length of America’s structurally deficient bridges if placed end-to-end would span nearly 1,760km, ARTBA’s examination of federal government data shows. The Brooklyn (NY), Arlington M
