Infrastructure Applications Testing for Interoperability
Interoperability is a key metric for success of ITS standards. To achieve interoperability, testing of V2X infrastructure applications requires a common methodology for verification and validation of these applications. The Infrastructure Applications Technical Committee (IATC) has recommended that certification of applications be performed based on specifications vetted through a consensus-based process. This project will develop a recommended practice test methodology for the different type of interface configurations supported by various IATC application specifications. Those 3 interface configurations are:
* broadcast interface (SAE messages broadcast using WSMP),
* localized data exchange interface (SAE data exchanges using WSMP or IP), and
* cloud based data exchange interface (SAE data exchanges using IP).
By creating a generalized test methodology for infrastructure-based applications interfaces and corresponding performance levels, adding application-specific test methodologies to exchange specific data objects over one of these three interface configurations creates a simple means of testing the applications themselves. When new infrastructure-based application standards are developed, the test methodology and required performance levels can be simply incorporated by reference, and the selected methodology can be pointed to by a particular standard based on the contents of the data exchanges and the performance requirements thereof.
Rationale: A common approach to testing of infrastructure-based V2X applications will facilitate application interoperability. This recommended practice will provide a common testing framework for testing infrastructure-based V2X applications defined in application standards developed by the IATC. In addition, this approach will streamline the standards development, implementation, and testing lifecycles for each new application standard.
