  • Abstract:
    This report documents the Intelligent Transportation Systems/Commercial Vehicle Operations (ITS/CVO) data architecture for the State of South Dakota. It details the current state of affairs in terms of CVO business areas, processes, data flow linkages and the systems used by each agency and for each process. This study also identifies the system deficiencies in terms of commercial vehicle information systems and networks (CVISN) deployment. Process and data models are developed using information engineering methodology/framework and software that are consistent with South Dakota's Bureau of Information Telecommunication's newly approved information engineering standards. The process model includes data flow diagrams (DFD) showing details of the information flow for each process and sub-process. The data model includes entity relationship diagrams (ERD) that show data attributes and major components associated with each key data entity. Interaction matrices are developed to show the linkages between data and processes and identify the level of data usage and sharing as well as any missing links in data exchange among agencies. The process-to-organization matrix maps the processes to the state agencies that perform the processes. A process-entity interaction or CRUD matrix maps the business area processes to the subject areas. The CRUD matrix shows data dependencies between the processes and subject areas. This report also identifies current system characteristics and deficiencies with regards to CVISN systems deployment. CVISN architecture top-level design templates and equipment packages are used as templates to summarize the data gathered in the study. The purpose is to gauge current systems' compatibility and to help identify areas of focus in developing and deploying CVISN in South Dakota. The templates reflect the major functions that support CVO in South Dakota and illustrate which functions currently exchange information. They also serve as starting points in developing operational scenarios and system interfaces. 7 Appendices, 7 tables, 11 figures. 202p.
