MPOs Data Archives - Archived Data Management Functionality
Subsystem Description
The Archived Data Management Subsystem (ADMS) collects, archives, manages, and distributes data generated from ITS sources for use in transportation administration, policy evaluation, safety, planning, performance monitoring, program assessment, operations, and research applications. The data received is formatted and tagged with attributes that define the data source, conditions under which it was collected, data transformations, and other information (i.e. meta data) necessary to interpret the data. The subsystem can fuse ITS generated data with data from non-ITS sources and other archives to generate information products utilizing data from multiple functional areas, modes, and jurisdictions. The subsystem prepares data products that can serve as inputs to federal, state, and local data reporting systems. This subsystem may be implemented in many different ways. It may reside within an operational center and provide focused access to a particular agency's data archives. Alternatively, it may operate as a distinct center that collects data from multiple agencies and sources and provides a general data warehouse service for a region.
Functional Area: Government Reporting Systems Support
Selects and formats data residing in an ITS archive to facilitate local, state, and federal government data reporting requirements.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall provide data from an ITS archive to federal, state, or local government reporting systems. | Existing |
| 2 | The center shall provide the capability to select data from an ITS archive for use in government reports. | Existing |
| 5 | The center shall provide the applicable meta-data for any ITS archived data to satisfy government reporting system requests. Meta-data may include attributes that describe the source and quality of the data and the conditions surrounding the collection of the data. | Existing |
Functional Area: ITS Data Repository
Collect and maintain data and data catalogs from one or more data sources. May include quality checks, error notification, and archive coordination.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall collect data to be archived from one or more data sources. | Existing |
| 2 | The center shall collect data catalogs from one or more data sources. A catalog describes the data contained in the collection of archived data and may include descriptions of the schema or structure of the data, a description of the contents of the data; e.g., time range of entries, number of entries; or a sample of the data (e. g. a thumbnail). | Existing |
| 3 | The center shall store the archived data in a focused repository that is suited to a particular set of ITS data users. | Existing |
| 4 | The center shall include capabilities for performing quality checks on the incoming archived data. | Existing |
| 7 | The center shall support a broad range of archived data management implementations, ranging from simple data marts that collect a focused set of data and serve a particular user community to large-scale data warehouses that collect, integrate, and summarize transportation data from multiple sources and serve a broad array of users within a region. | Existing |
| 10 | The center shall respond to requests from the administrator interface function to maintain the archive data. | Existing |
