GT SignApp

GT SignApp is a field data collection tool built by the Georgia Institute of Technology, School of Civil and Environmental Engineering, for a research study on roadway sign condition and inventory. This app is currently used as part of a research study conducted by Georgia Tech. It works only with an account issued by the research team to participants enrolled in the study; there is no public sign-up. WHAT IT DOES Enrolled participants use the app to capture video of roadway environments while driving a planned route. Each recording is paired with a GPS track logged during the recording, so the footage can be located along the route during later analysis. Recordings are held on the device until the participant chooses to upload them, at which point they are compressed and transferred to a Georgia Tech research server. FEATURES - Landscape, full-screen camera capture at a fixed frame rate, with no audio recorded - Continuous GPS logging written alongside each recording - A recordings list showing what has been captured, its size, and its upload state - Uploads that continue after the app is moved off screen, with per-item retry - Storage checks before each upload so a transfer is not started without room to prepare it DATA COLLECTED The app records video and precise location, and transmits both, together with the participant's account identity, to Georgia Tech infrastructure. It records no audio. It contains no advertising, no analytics SDKs, and no third-party tracking of any kind. Collected data is used only for the research study. The privacy policy linked on this page describes exactly what is stored, where it goes, and how to ask for it to be deleted. REQUIREMENTS - An account issued by the Georgia Tech research team - Camera and location permissions - iOS 15.5 or later - Substantial free storage, since video is retained on the device until uploaded
