Traffic Weather - Safe Arrival with the Right Measurement Technology

Black-ice early warning systems help you to operate a proactive winter service and keep critical microclimates such as bridges constantly in view.
Mobile and stationary measuring technology gives you information at any time - not only about individual measuring points, but also about the road conditions throughout your entire road network.
Traffic Management Systems (TMS) require real-time information, not only about road conditions but also about wind conditions (on bridges) as well as visibility, in order to display the optimum speed in each case via variable warning signs.

Water film height and aquaplaning risk:

Water film height is measured in micrometers. From as little as 10 micrometers, a road is no longer dry. With more than 700 micrometers (0.7 mm), there is a risk of aquaplaning.

Grip and the influence of weather:

The grip depends on the tire, the asphalt and the water / snow / ice layer. This weather-related intermediate layer is the key factor as far as friction is concerned.

Mobile vs. single point / stationary measurement:

A single measurement point is often not representative of the actual road condition. Optical, non-contact methods sample a representative surface area instead of a point. They also measure up to 100 times per second, while the measuring vehicle is in motion.
