Perciv AI selected by the Dutch Road Authority to map tunnels for safety

When we say Perciv AI's main drive is road safety for all 🚗, we mean it—not just by developing the next generation of radar perception, but by understanding the limits of the current generation.

That's why, when Rijkswaterstaat, the Road Authority of the Netherlands 🇳🇱, asked for our help, we didn't hesitate to say yes ✅.

Current radar systems, which don't detect elevation and rely on conventional perception algorithms, often get confused in tunnels 🚧. Reflections from ceilings and walls can be mistaken for obstacles on the road, leading to dangerous "phantom braking" at high speeds ⚠️.

Rijkswaterstaat asked us to use our next-gen 4D radars along with our multi-sensor recording stack (including lidar, camera, and odometry) to map multiple tunnels across the Netherlands, identifying potential danger spots. Some tunnels had to be temporarily closed 🛑 (sorry commuters!), while others aren't even open to the public yet.

The results are 3D maps of the tunnels with centimeter accuracy and with a radar heatmap overlaid, with which we can identify problematic locations and objects, and increase the safety of these tunnels!
