Overview
Standard overview
SAE J2735 defines standardized V2X messages and data elements, including BSM, SPaT, MAP, and traveler information. It matters to V2X because it gives independently developed systems a common technical contract. Related radio, networking, message, security, charging, or conformance standards still have to be implemented together where the complete system requires them.
