This document provides the necessary testing & validation methodology to verify the accuracy and utility of SPaT to support red light violation warning by defining: 1. Connected intersections performance criteria to meet needs of the in-vehicle application addressing message accuracy, latency, stability and reliability of information flow. 2. Test procedures and tools to determine how accurate the broadcast SPaT message data are relative to the actual signal controller actions for phase start time and the duration. This report also contains the following: 1. Analysis of the accuracy of broadcast SPaT message relative to the actual signal controller actions for phase start time and the duration. 2. Analysis of the information processing latency of each link of the data flow across multiple devices for common connected intersection configurations. 3/ Analysis of the stability and reliability of the information flow to connected vehicles.

This document is an update of the Connected Transportation Interoperability (CTI) 4501 - Connected Intersections (CI) Implementation Guide v1.01. The existing document defines minimum requirements and provides guidance for nationally interoperable connected intersections that support interoperable applications for signalized intersections. The document will update and enhance guidance for: - required CI capabilities for infrastructure devices, including J2735 SPaT and MAP messages, and to provide signal timing assurance - providing positioning information by infrastructure devices - providing assurance of security for infrastructure devices - documenting systems integration considerations

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.
