Recommended Practices for Signalized Intersection Applications J2945/B

This document outlines how to use SAE J2735 and other related information for signalized intersection applications. The document focuses on how to use SPaT and MAP messages to support signalized-intersection applications. In general, implementation guidance is necessary to achieve interoperability by addressing the requirements for the options for both over the air dialogs and message contents, and to support larger intersection maps  This document also addresses using Signal Request & Signal Status messages corresponding to vehicle functionality and approaches to traffic signal priority/pre-emption (TSP), including three different methods for implementing TSP over the air. The project is complementary to the connected intersections project being performed by ITE.
