National ITS Architecture Functional Requirements
associated with Research and Data Collection Center:

ITS Data Repository

1. The center shall collect data to be archived from one or more data sources.
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).
3. The center shall store the archived data in a focused repository that is suited to a particular set of ITS data users.
4. The center shall include capabilities for performing quality checks on the incoming archived data.
5. The center shall include capabilities for error notification on the incoming archived data.
6. The center shall include capabilities for archive to archive coordination.
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.

Traffic and Roadside Data Archival

1. The center shall manage the collection of archive data directly from collection equipment located at the roadside.
2. The center shall collect traffic sensor information from roadside devices.
3. The center shall collect environmental sensor information that from roadside devices.
4. The center shall respond to requests from the Archive Data Administer to input the parameters that control the collection process.
5. The center shall send the request for data and control parameters to the field equipment where the information is collected and returned.
6. The center shall record the status about the imported traffic and roadside data.
7. The center shall use the status information to adjust the collection of traffic and roadside data.
