SAE J2735 DSRC Message Set
|
This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.

CTI 4501 CI Implementation Guide
|
This Connected Intersection (CI) Implementation Guide defines the key capabilities and interfaces a connected signalized intersection must support to ensure interoperability with production vehicles for state and local IOOs. A connected intersection is defined as an infrastructure system that broadcasts SPaT, MAP, and position correction data to vehicles.

ISO 19091 V2I for signalized intersections
|
This technical specification defines messages and related data structures and data elements for the following exchanges between roadside equipment and vehicles: 1) Definition of the SPaT (signal phase and timing) message transmitted from a traffic controller that describes the state of the signals, signal timing as necessary to support the applications identified herein; 2) definition of the MAP message (which include the definition of motorized lane, vehicles, busses, trams, bicycle, pedestrian crosswalks, etc.); and 3) definition of the messages (SRM, SSM) to be exchanged between an intersection traffic controller and approaching vehicles to support priority treatment as might be expected for emergency response , freight transport, and public transport vehicles to improve safety.

SAE J2945/B Signal Intersection Applications
|
This document provides guidance on usage of 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.
