IN Brief:
- Econolite will deploy Ouster BlueCity at another 160 Utah intersections under a multimillion-dollar expansion.
- OS1 Max REV8 lidar adds detection at up to 500 feet and combines 3D depth with optional colour data.
- The agreement takes Utah's contracted BlueCity footprint to nearly 300 intersection and roadway deployments.
Ouster will expand its BlueCity lidar traffic-management system across another 160 intersections in Utah after Econolite secured a multimillion-dollar contract extension from the Utah Department of Transportation.
The new deployment uses Ouster’s OS1 Max REV8 digital lidar sensor and follows an earlier Utah programme covering more than 100 intersections with REV7 hardware. Once the expansion is included, Ouster says the state’s contracted BlueCity footprint will approach 300 intersection and roadway deployments.
REV8 extends detection to as much as 500 feet for corridor-level traffic monitoring and combines three-dimensional lidar data with optional colour capture. The additional image information can make recorded events and configured zones easier for operators to interpret, while the lidar continues to provide the depth and movement information used by the traffic-management software.
The company has also added privacy processing at the edge. Pedestrians and cyclists can be blurred in colour imagery while their presence and movement remain available to the perception system, addressing one of the more obvious concerns created when roadside sensing moves from abstract point clouds towards richer visual records.
BlueCity links the sensors to Ouster’s perception software for actuation, alerts, and analytics. The Utah installations will integrate with the state’s existing traffic-control environment, including Econolite Cobalt signal controllers, through an open API rather than requiring the entire intersection-control stack to be replaced.
That is important because transport authorities typically operate infrastructure accumulated over many years. A new sensor is easier to deploy if it can work with installed controllers and roadside units rather than forcing a wholesale change to hardware that may still have significant service life remaining.
Ouster says BlueCity can be installed non-intrusively in as little as three to five hours per intersection. Once operating, the system can create a live three-dimensional representation of traffic and use detected demand to influence signal actuation, while longer-range tracking provides data across a corridor rather than treating each junction as an isolated sensing point.
The cited applications include extending pedestrian crossing times for slower users, detecting vehicles in dilemma zones around changing signals, issuing turning-vehicle yield warnings, and feeding vehicle-to-everything safety alerts through roadside units. Each depends on the same underlying requirement: identifying road users, tracking their movement, and determining when trajectories or timing create a potential conflict.
The contract follows an evaluation carried out by the Utah State Evaluation Committee in December 2024. Ouster says six lidar proposals were assessed and that the Econolite/Ouster solution received the highest overall vendor score, ranking first in lidar hardware and perception software. That is a supplier-reported result, but it provides useful context for why the state expanded an existing deployment rather than starting again with a different sensing platform.
For a sensor manufacturer, the more important test begins after the pilot stage. A system operating at a handful of junctions can be maintained closely and adjusted manually; a network approaching 300 locations demands repeatable installation, calibration, software management, cybersecurity, fault diagnosis, and consistent perception across different road layouts and environmental conditions.
Ouster positions the system for operation in adverse weather and lighting and says the platform meets system-level NEMA TS2 requirements and ISO 27001 cybersecurity provisions. Those characteristics become commercially more relevant as lidar moves from technology demonstrations into state-level infrastructure procurement, where maintenance and interoperability can matter as much as raw sensing performance.
The Utah expansion is also distinct from Ouster’s recent quarterly shipment figures. Unit volumes show that lidar hardware is moving into the market, but they do not reveal how sensors are being incorporated into operational infrastructure. Here the lidar forms part of a defined architecture that includes signal controllers, perception software, APIs, roadside communications, and specific safety applications.
The first REV8-equipped BlueCity installation is already operating in Utah, giving the larger rollout a live reference point. The engineering question now is whether long-range detection, optional colour data, edge privacy, and controller integration remain manageable when repeated across a statewide network rather than demonstrated at one or two showcase intersections.
