National ITS Architecture Functional Requirements
associated with Smart Travel Lab:

Archive Situation Data Archival

1. The center shall provide the capability to adjust the collection of field-sourced data based on the statistical measures.
2. The center shall provide the capability to execute methods on the incoming field data such as aggregation and statistical measures before the data is stored in the archive.
3. The center shall respond to requests from the administrator interface function to manage field-sourced data collection.
4. The center shall collect data from roadside devices.

Archive Data Repository

1. The center shall collect data from data distribution systems and other data sources.
2. The center shall respond to requests from the administrator interface function to manage center-sourced data collection.
3. The center shall collect data from centers.
4. 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).
5. The center shall store collected data in an information repository.
6. The center shall perform quality checks on collected data.
7. The center shall notify the system operator of errors related to data collection, analysis and archival.
8. The center shall respond to requests from the administrator interface function to manage the archive data.
9. The center shall include capabilities for archive to archive coordination.
10. The center shall provide the capability to execute methods on the incoming data such as cleansing, summarizations, aggregations, or transformations applied to the data before it is stored in the archive.
11. The center shall respond to requests for archive data from archive data users (centers, field devices).
12. The center shall provide a mechanism for archive data users to request archive data by meta-data range.

Archive Government Reporting

1. The center shall provide the capability to format data suitable for input into government reports.
2. The center shall respond to requests for government report data.
3. The center shall provide archive data to federal, state, and local government reporting systems.
4. 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.
