Abstract:This document is the System Architecture Document (SAD) for the University of Washington’s (UW) Transportation Data Equity Initiative (TDEI) Project for the United States Department of Transportation’s (USDOT) ITS4US Program. The SAD describes the system architecture from various architecture perspectives including: Enterprise Architecture View; Physical Architecture View of Systems, Interfaces, and Service Packages; Functional Architecture View; Data and Information Flow View; Communications Architecture View; and Security Architecture View. The System-of-Interest described in this document is a data management system that collects, stores, and distributes detailed sidewalk, transit station, and on-demand transit data. This data management system is supported by Application Program Interfaces, or APIs, through which data generators can submit data and data consumers can request data. In addition, as part of this work, a tool will be developed to help data generators convert their existing sidewalk and/or transit databases into the data standards used by this system. This document describes the System Architecture for these systems, their interfaces, data flows and functional components.
