Radars have recently become more common as detection devices at traffic light intersections, replacing inductive loops in many cities.

Vehicle detection is used to enable more dynamic control of traffic signals. Instead of traditional fixed, time-based control cycles, detecting approaching vehicles allows for adjusting signal changes—such as extending green lights—or granting priority to certain vehicle groups, such as public transport, heavy vehicles, or emergency services. Additionally, detection data can be recorded, enabling post-analysis of traffic flow.

Radars are gaining popularity due to:

accurate vehicle detection
reliable performance in all weather conditions
providing richer traffic data
installation and maintenance without disrupting traffic
easy virtual configuration of detection zones

Smartmicro radars adapt to many uses

For years, Nodeon has represented one of the world’s leading and most advanced radar equipment manufacturers: the German company Smartmicro. With hundreds of radar installations, we are the most experienced partners for implementing this technology at traffic light intersections in Finland.

We use radars in their traditional role as replacements for inductive loops, but we also implement significant value-added services for our customers—such as digital twins of traffic light-controlled intersections.
