Utah DoT installs lidar tech at Salt Lake City intersection

A ‘groundbreaking’ traffic signal system powered by lidar sensor data has been deployed at an intersection in Utah state.

Initiated by the Utah Department of Transportation (UDoT), the project addresses critical needs for advanced sensor technology that can detect, count, and track vehicles and other road users under any weather conditions.

3D Perception Engine

The installation in Murray, located in southern Salt Lake City, is powered by Seoul Robotics’ 3D Perception Engine, housed in a compact edge device, and utilises lidar sensors at each corner of the intersection. The 3D Perception Engine, developed by the autonomous driving company, uses lidar data to create a digital twin of the intersection to feed data to optimise traffic flow and reduce congestion.

The lidar-based system supports traffic management features, including precise stop-bar detection, advanced vehicle detection up to 300 feet from the stop bar, and red light running, Seoul Robotics claims. Additionally, the system boasts a vehicle counting accuracy of 99.8 per cent at the stop bar.

“Since its installation, our lidar-based traffic management system has consistently demonstrated excellent detection and tracking of objects, ensuring reliable performance across all weather conditions”

It is a collaboration between Seoul Robotics, Gades Sales Company, and Blue Band. Gades Sales Company, the local distributor was integral to the installation and ensuring the system was optimally integrated into the local infrastructure.

Meanwhile, Blue-Band’s software acts as a critical interface, translating the data processed by Seoul Robotics’ 3D Perception Engine into signal commands compatible with existing traffic controllers. This collaborative effort guarantees the system’s adaptability to all commonly used traffic controller models in the US.
