Ouster LiDAR Powers the Nation's Largest Smart Traffic Network Deployment

$2M Strategic Partnership Deploys 100 Intelligent Nodes Across Tennessee

Ouster eploys its Ouster BlueCity traffic management solution in Chattanooga, Tennessee to improve roadway safety and reduce congestion.Following a successful pilot at 12 intersections, the City of Chattanooga will expand Ouster’s BlueCity solution to over 120 intersections, covering the downtown area. With this expansion, Ouster BlueCity will be the largest deployment of lidar detection technology for traffic and pedestrian safety in the United States. The project will combine digital lidar sensors and edge AI at each intersection to manage traffic flow, detect and analyze safety incidents and provide detection for vehicle-to-everything (V2X) communications.

Digital Perception-Decision Systems Redefining Urban Mobility

Ouster BlueCity is a turnkey solution that delivers more intelligent signal actuation at intersections while generating an analytics data stream that gives traffic operators and city planners high quality insights about their public corridors. Ouster BlueCity combines digital lidar with perception software and data analytics, enabling the creation of a real-time 3D digital traffic twin of an intersection or road. The solution automates data collection in the cloud to monitor road events more accurately for vehicles, pedestrians and cyclists, enabling quick safety interventions and long-term planning optimizations. Using deep learning AI perception, Ouster BlueCity delivers reliability and advanced object classification and detection for a range of complex use cases including traffic actuation, near-miss detection, outside of crosswalk events, red light running and wrong-way driving. This technology will enable optimized traffic signal management on roads and intersections to improve traffic flow.

Multidimensional Environmental Perception Empowering City Governance

Ouster BlueCity is already deployed at hundreds of intersections around the world with more underway as municipalities take steps to modernize their traffic infrastructure.

Professor Mina Sartipi, Director of the Urban Informatics Research Center at the University of Tennessee, stated: In the pilot crosswalk area, the intelligent zebra crossing system based on LiDAR point cloud data has achieved a record of zero near-miss incidents.

Asad Lesani, Vice President of Smart Infrastructure Products at Ouster, emphasized: Each intersection equipped with BlueCity creates dual value—preventing potential loss of life from traffic accidents and enhancing urban transportation operational efficiency.
