Summary
This document serves as the Phase 1 Human Use Approval Summary (HUAS) for the Safe Trips in a Connected Transportation Network (ST-CTN) project, part of the Atlanta Regional Commission’s ITS4US Deployment Program. The project addresses the challenge of providing efficient, accessible, and safe multimodal transportation for underserved communities, specifically targeting individuals with physical or cognitive disabilities, older adults, those with limited English proficiency, and low-income residents. The primary motivation is to leverage intelligent transportation systems (ITS) to support "complete trips" for these vulnerable populations in Gwinnett County, Georgia, an area characterized by suburban land uses and inconsistent pedestrian infrastructure. The methodology involves the development and deployment of an integrated system combining connected vehicle technology, transit signal priority, machine learning, and predictive analytics. Central to the project is the ATL RIDES mobile application, which provides personalized trip planning, navigation, and safety alerts. The document details the Institutional Review Board (IRB) process required for human subjects research, focusing on the protection of personally identifiable information (PII) and participant safety. The research plan outlines interactions with participants through the mobile app, including data collection via logs, trip feedback, and crowdsourced information. The team relies on prior IRB certifications from 18 previous protocols to structure the current applications, ensuring compliance with federal standards. The HUAS integrates with other project documents, such as the Concept of Operations, Data Management Plan, and Safety Management Plan, to define participant burden, risk assessment, and informed consent procedures. The findings presented in this summary are procedural rather than empirical, as the document reports on the status of regulatory approvals rather than experimental results. It confirms that the project team has established the necessary IRB protocols for Phase 1, documenting the approval status, conditions, and feedback received from the review board. The document identifies specific data streams requiring IRB oversight, including user profiles, trip plans, and safety messages. It emphasizes that no human subject interactions will occur until all applicable protocols are approved. The summary also outlines the framework for future phases, noting that survey instruments for evaluating user experience and safety perceptions will be designed in Phase 2. The team has committed to maintaining strict adherence to IRB terms, recognizing that protocol amendments are difficult to obtain once recruitment begins. The significance of this work lies in its establishment of a compliant framework for deploying advanced transportation technologies in ways that prioritize the privacy and safety of vulnerable users. By securing IRB approval for the ST-CTN system, the project ensures that the integration of connected vehicles and mobile applications respects ethical standards for human subjects research. This approval enables the transition from concept development to design, testing, and eventual operations. The document underscores the importance of comprehensive protocol development to avoid schedule delays and budget impacts associated with IRB modifications. Ultimately, the HUAS facilitates the deployment of a replicable mobility solution that aims to enhance independence and accessibility for underserved travelers while maintaining rigorous data protection standards.
Key finding
The document establishes the regulatory framework and IRB approval process for human subject research within the ST-CTN deployment project, ensuring compliance with privacy and safety standards before participant interaction begins.
