Intelligent Transportation Systems (ITS) standards are industry-consensus standards that provide the details about how different systems interconnect and communicate information to deliver the ITS user services described in the National ITS Architecture. These standards are intended to meet specific communications needs for ITS. They provide for consistent messages and specify the information elements that make up those messages. Some of them address communications protocols or define how existing, more general standards should be applied to ITS services. |
