Infrastructure Connectivity Certification Test Procedures for Infrastructure-Based Connected Automated Vehicle Components Traveler Information Message – SAE J2735

The successful deployment and operation of connected vehicle systems will require that devices, systems, and applications developed by different providers be compatible, interoperable, non-interfering, and, in some instances perhaps, interchangeable. In addition, some devices, systems, and applications, e.g., active safety applications, may be required to meet minimum operational performance standards. A list of questions was distributed to potential stakeholders to gather information on which aspects of the industry should be considered for certification. The results of this effort were compiled and consolidated into a list of recommendations that yielded five test plans to be addressed under this project. Two separate test plans certify signal phase and timing (SPaT) messages and applications related to the following two items: National Transportation Communications for Intelligent Transportation Systems Protocol (NTCIP) 1202 v3 objects and SAE International (SAE) J2735 messages. The other three test plans certify the MAP message, traveler information message (TIM), and personal safety message (PSM) as defined in J2735. This document contains the test plan and test design for one of the five messages: TIM. The scope of the test cases contained in this document is to evaluate the output of a TIM application which encodes elements of TIM data into an SAE J2735 TIM over available wireless technology. This test plan is intended to evaluate the format, structure, and encoding of the TIM. SAE J2735 Standard governs the TIM format and structure. The message is presented in the Abstract Syntax Notation One (ASN.1) format, which is UPER Hex encoded for broadcast. The scope for testing includes various mandatory data elements and their corresponding values, along with the verification of the various format conversions. Various sources for the TIM information would be considered. This document focuses on the ingestion of the information from its source and its eventual conversion to UPER Hex for broadcast.
