Communications Solutions
Communications standards support efficient implementation of the Regional ITS Architecture over time. They facilitate deployment of interoperable systems at local, regional, and national levels without impeding innovation as technology advances, vendors change, and new approaches evolve. Since it takes more than one standard to implement an interface, ARC–IT groups all the standards required to implement a particular interface into a 'Communications Solution'. The table below identifies each of the Communications Solutions that may apply to the Regional ITS Architecture. Each solution is a link to a page that identifies the standards included in the solution, any issues that have been identified for the solution, and the portion of the Regional ITS Architecture that may be supported by the solution.
