Indianapolis ITS Architecture
ITS standards are fundamental to the establishment of an open ITS environment. Standards are important components of the information flows in ITS Architectures. They facilitate deployment of interoperable systems at local, regional, and national levels without impeding innovation as technology advances and new approaches evolve.
The Indianapolis Regional ITS Architecture (RITSA) identifies the ITS standards that are applicable to the ITS activities in the region. Their use encourages interoperability among systems, and stakeholders are strongly encouraged to use the applicable standards when feasible.
The Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT) presents communications solutions which associate sets of standards for consideration to address an interface or information flow implementation. Along with the communications solution details is a Readiness Description that provides insight into the solution regarding issues that may exist with the readiness of the standards in the solution. This information is provided for informational purposes to the user for further investigation of the standards to make sure all aspects are known during development and deployment timeframes for an applicable ITS implementation. The readiness information is captured from ARC-IT as additional information that should be verified by the user given the constantly evolving standards development environment and changing status.
The following list provides all ITS standards that are applicable in the Indianapolis RITSA, and the information flows to which each applies. Each standard is hyperlinked to the Indianapolis RITSA's information flows to which that standard may apply.
