How Self-Driving Cars Detect Cones for Traffic Control

Autonomous vehicles rely on advanced technologies to detect and interpret cones for traffic control. These systems ensure that self-driving cars navigate safely through construction zones, temporary detours, and other dynamic road environments. Below, you will explore the key technologies that enable this detection process.

The Role of LIDAR in Traffic Cone Detection

LIDAR (Light Detection and Ranging) plays a crucial role in helping autonomous vehicles identify traffic cones. This technology uses laser pulses to create detailed 3D maps of the surrounding environment. By analyzing the reflections of these laser beams, LIDAR systems can accurately detect objects, including traffic cones, even in complex settings.

For example, a LiDAR-Based Traffic Cone Detection Prototype demonstrated how this technology can pinpoint the exact location and shape of traffic cones.
