Municipal TOCs
TxDOT Paris District TMC
TxDOT Transportation Planning and Programming Division

Functional Requirements:

1The center shall collect traffic management data such as operational data, event logs, etc.
2The center shall assign quality control metrics and meta-data to be stored along with the data. Meta-data may include attributes that describe the source and quality of the data and the conditions surrounding the collection of the data.
3The center shall receive and respond to requests from ITS Archives for either a catalog of the traffic data or for the data itself.
4The center shall be able to produce sample products of the data available.
  

User Service Requirements (fully or partially addressed):

7.0INFORMATION MANAGEMENT
7.1ARCHIVED DATA FUNCTION
7.1.0ITS shall provide an Archived Data Function to control the archiving and distribution of ITS data. The Archived Data User Service provides the Historical Data Archive Repositories and controls the archiving functionality for all ITS data with five major functions: 1) the Operational Data Control function to manage operations data integrity; 2) the Data Import and Verification function to acquire historical data from the Operational Data Control function; 3) the Automatic Data Historical Archive function for permanently archiving the data; 4) the Data Warehouse Distribution function, which integrates the planning, safety, operations, and research communities into ITS and processes data products for these communities; and 5) the ITS Community Interface which provides the ITS common interface to all ITS users for data products specification and retrieval. ADUS helps achieve the ITS information goal of unambiguous interchange and reuse of data and information throughout all functional areas.
7.1.3The Archived Data Function shall include a Data Import and Verification (DIV) function to acquire historical data from the Operational Data Control function.
7.1.3.1DIV shall be capable of importing selected ITS Operational data from the ITS Operational Repositories.
7.1.3.1.1DIV shall be capable of importing ITS Freeway Operations data to include:
7.1.3.1.1(a)Freeway traffic flow surveillance data.
7.1.3.1.1(b)Ramp meter preemptions.
7.1.3.1.1(c)Ramp meter operational data.
7.1.3.1.1(d)Freeway visual and video surveillance data.
