OST - CCDS - PIA -2025.pdf

The Bureau of Transportation Statistics (BTS) operates and maintains the Close Call Data System (CCDS) to store, process, and access various confidential data collection programs. These data are collected and protected under the Confidential Information Protection and Statistical Efficiency Act (CIPSEA, Title III of the Foundations for Evidence-Based Policymaking Act of 2018, Pub. L. No. 115-435, codified as amended at 44 USC 3561-3583), which requires BTS to protect the trust of providers of information by ensuring the confidentiality and exclusive statistical use of their responses. BTS data collections conducted under CIPSEA include near-miss and safety data collection programs, supply chain and freight-related data collection programs, and certain transportation surveys. This Privacy Impact Assessment (PIA) is an update to the previously published PIA.  It is being updated in accordance with the E-Government Act of 2002 to assess the potential privacy risks associated with the system’s operations and ensure compliance with applicable data protection regulations and safeguarding of individuals' personal information. The assessment aims to identify and mitigate privacy risks, ensuring that data handling practices align with legal and organizational standards.
