What Is SDC?

The Secure Data Commons (SDC) is a cloud-based analytics platform that enables traffic engineers, researchers, and data scientists to access transportation-related datasets. The U.S. Department of Transportation (USDOT) created the SDC to provide a secure platform for sharing and collaborating on research, tools, algorithms, and analysis involving moderate sensitivity level (PII & CBI) datasets using commercially available tools, without needing to install tools or software locally.

The SDC offers a common platform for innovative data analysis and sharing of results that cuts across the Department's data silos.


How It works

With a robust security architecture that secures datasets and user workstations, the SDC:

Leverages cloud capabilities to share complex (high volume, velocity, or variety) transportation datasets with the transportation research community

Provides authorized access to users through a data use agreement with revocable access terms to protect the sensitivity of the data

Enables scalable data storage and analysis and user access protocol via cloud-based platforms


Ensures that sensitive data are protected through adherence to USDOT's security standards for information technology

Provides users with predefined tools for data analysis and encourages the creation of custom toolsets, open sharing of code, and addition of datasets among the user community
