The PKI 5670 Stationary Laser Speed Monitoring is based on a laser measuring principle. A scanning laser is used here which determines the speed and position of all vehicles in the tracking zone via a time-of-flight measurement. The PKI 5670 Stationary Laser Speed Monitoring consists of rotating segments so that the traffic can be monitored in both directions of travel. In-road equipment, such as piezo sensors or induction loops, is not required. The elegant and inconspicuous design fits into any town- or landscape. It is possible to monitor up to three lanes in both directions from the central reservation. The digital documentation is encrypted which thus protects against manipulations. The PKI 5670 system operates irrespective of the time of day, weather conditions and traffic density.
