Nashville 100+ deplpyment

Ouster was awarded a multimillion-dollar contract by the City of Nashville, Tennessee, to deploy its complete traffic management solution, Ouster BlueCity, at more than 100 intersection and roadway sites following successful pilots and deployments in key locations. This initiative is a collaborative effort with the Nashville Department of Transportation and Multimodal Infrastructure (NDOT), Vanderbilt University and Ouster BlueCity distributor Southern Lighting & Traffic Systems (SLTS) to enhance mobility and safety in the city.

This expansion follows successful pilots at 8 locations in the north Nashville area and a 5-intersection corridor deployment on Broadway, Nashville’s famous Honky Tonk Highway, which attracts an estimated 17.3 million tourists and country music lovers annually. The City is leveraging 3D LiDAR to move towards corridor-level analytics across a multi-mile stretch in Nashville. By using the latest advancements in distributed perception, which stitches together 3D LiDAR data from multiple intersections into a single view, the City can access corridor-level detection of multimodal road user movements. Today, the Broadway deployments are helping to manage large crowds, congestion and road closures that often occur in the thriving tourist area.

This latest 100+ location expansion is a cornerstone of Nashville’s Choose How You Move program, the City’s voter-approved transportation improvement initiative. By integrating Ouster BlueCity into this city-wide modernization effort, NDOT is moving beyond traditional infrastructure to a smart signal network that prioritizes safety. This deployment provides the high-fidelity, real-time, anonymized data necessary to help meet the program's goals: reducing transit delays, protecting vulnerable road users (VRUs), and ensuring that Nashville’s corridors are safer and more efficient for everyone, whether they walk, bike, ride transit, or drive.

By harnessing Ouster BlueCity, the latest 100+ site deployment enables Nashville to provide:

• Dynamic signal optimization: Improving daily traffic flow and congestion based real-time road user demands.

• Intelligent traffic management & emergency response: Leveraging LiDAR data for proactive road closures and emergency vehicle management during large events.

• VRU protection: Detecting safety events such as near-misses and pedestrians outside of crosswalks, as well as managing large crowds.

• Automated 24/7 data analytics: Replacing manual traffic and safety counts with automated data analytics and event recordings across varied environmental and weather conditions for improved planning and interventions.
