The US Department of Transportation (USDOT) released data collected for the Intersection Safety Challenge Stage 1B: System Assessment and Virtual Testing on the US DOT ITS DataHub for further research and development to transform intersection safety.

Multi-sensor data were collected at a controlled test roadway intersection at the Federal Highway Administration (FHWA) Turner-Fairbank Highway Research Center (TFHRC) Smart Intersection facility in McLean, VA from October 2023 through March 2024.

The data include potential conflict-based and non-conflict-based experimental scenarios between vulnerable road users (e.g., pedestrians, bicyclists) and vehicles during both daytime and nighttime conditions. (Please note that no one was harmed in the data generation process.)

The Stage 1B Challenge Dataset includes data at a single, signalized four-way intersection from 20 roadside sensors and traffic control devices, including eight closed-circuit television (CCTV) visual cameras, five thermal cameras, two light detection and ranging (LiDAR) sensors, and four radar sensors.

The data can be used to develop and train models that can anticipate potential conflicts and provide enough time for warnings or other real-time countermeasures. This rich and unique dataset lays the foundation for key research efforts aimed at improving intersection safety.

A sample from the Stage 1B Challenge Dataset is provided for download, inspection, and use on the ITS DataHub.
