UDOT LiDAR Freeway Data Collection System

The UDOT LiDAR freeway data collection project improves traffic monitoring and safety across Utah’s statewide freeway network. The Utah Department of Transportation (UDOT) launched this initiative as part of a broader effort to modernize infrastructure and support connected vehicle technology. As a result, the project helps deliver more accurate and actionable traffic data.

Because freeway conditions change rapidly, reliable and real-time data is essential. Therefore, UDOT invested in advanced LiDAR detection technology to improve visibility across multiple lanes. In addition, this effort supports long-term planning and enhances roadway safety.

Project Snapshot

Key Project Outcomes

• High-resolution, real-time traffic data collection
• Improved visibility across multi-lane freeway segments
• Enhanced support for V2X deployment initiatives
• Non-intrusive sensor installation with minimal disruption
• Better data for planning and operational decision-making

UDOT’s LiDAR deployment delivers detailed, real-time traffic insights that support safer and more efficient freeway operations.

Program Background

This project is part of the Federal Highway Administration’s Saving Lives with Connectivity initiative. The program focuses on accelerating Vehicle-to-Everything (V2X) deployment across the United States. In June 2024, UDOT received $20 million in funding to support these efforts. As a result, the agency advanced several projects designed to improve safety and mobility.

Because V2X systems rely on accurate data, advanced detection technologies are essential. Therefore, UDOT selected LiDAR sensors to enhance freeway data collection capabilities.

Project Overview

In 2025, UDOT selected Econolite to deliver a non-intrusive LiDAR detection solution. Econolite partnered with Ouster, a global provider of high-performance LiDAR sensors. Together, they developed a system that captures detailed traffic data across freeway segments. In addition, the solution integrates with UDOT’s existing Intelligent Transportation Systems.

As a result, the State can collect and analyze data more efficiently. Moreover, improved data resolution supports better planning and operational decisions.

LiDAR Detection System Deployment

The deployed system uses advanced LiDAR sensors combined with perception software to monitor traffic conditions. These sensors are mounted on poles along freeway segments, which eliminates the need for intrusive roadway installation. Therefore, deployment can occur with minimal disruption to traffic.

The system captures continuous, lane-by-lane data across up to 12 lanes. This includes vehicle speed, lane occupancy, traffic volume, and classification. In addition, the sensors operate effectively in various lighting and weather conditions. As a result, UDOT gains consistent and reliable traffic insights.

ITS Integration and Edge Computing

The LiDAR system integrates directly into UDOT’s existing ITS infrastructure. In addition, data is processed using edge computing technology. This allows information to be analyzed near the source, reducing latency and improving response time. Consequently, traffic managers can make faster and more informed decisions.

Because the system operates in real time, it supports both current operations and future connected vehicle applications. Moreover, this integration enhances the overall efficiency of the transportation network.

Operational Benefits

The UDOT LiDAR freeway data collection project delivers several important benefits. First, high-resolution data improves visibility into traffic patterns. Next, real-time insights support quicker operational responses. In addition, non-intrusive deployment reduces installation impacts. Furthermore, integration with ITS systems enhances overall performance. As a result, UDOT can manage its freeway network more effectively and safely.
