Center-to-Center Standards

Concept of Operations and Requirements
The AZTech™ Center-to-Center Specification has been developed through the consensus input of regional stakeholders. Following a Systems Engineering Methodology, a user needs assessment and concept of operations (ConOps) were developed. Based on the ConOps, system functional requirements and a regional stakeholder agreement were then developed.

The system functional requirements for DMS (Dynamic Message Signs) and TMS (Traffic Management Systems) are the basis for development of the technical specifications for information exchange among centers in the region.

System Interface Specifications
The technical specification is based on stakeholder input and review of the requirements analysis and design presented herein at a stakeholder workshop held on June 14, 2006. The final specification in PDF format, and WSDL and XML schema are available from the links at left. The WSDL and XML Schema files were validated using XML Spy. A security white paper has also been developed to address web services SOAP Message security based on the OASIS standard.
