Connected Intersections Implementation Guide - Testing and Validation Guidance

CTI 4501/4_202610 (Current)

10/26/2026

CTI 4501 defines the key capabilities and interfaces a connected signalized intersection must support to ensure interoperability with vehicles, including production vehicles, for state and local Infrastructure Owner Operators (IOOs). A connected intersection is defined as an infrastructure system that broadcasts SPaT, MAP, and optionally position correction data to vehicles. The CTI 4501 family of documents define procurement and implementation guidance and the expectations leading to minimum performance requirements for a connected intersection. It is intended to be used by IOOs to provide guidance on how to implement an interoperable connected intersection. For OEMs and other application developers, these recommended practices provide an explanation on what data and connected vehicle messages are being provided from an interoperable connected intersection so safety applications can be developed for production vehicles, with an initial focus on the Red Light Violation Warning (RLVW) application. Although the focus is on the RLVW application, requirements for other V2X applications related to connected intersections, including requirements for traffic signal controllers to generate the SPaT information, are also addressed assuming the connected intersection configuration and messages can support them and no significant effort was needed. The Needs to Requirements Traceability Matrix (NRTM) in CTI 4501, 6.2.3, provides the guidance to IOOs for the procurement of a connected intersection. Recognizing that some stakeholders require more in-depth guidance on specific aspects of connected intersections, Version 2 of the CI Implementation Guide has been reorganized into a main document and several companion subdocuments. The main document establishes the overarching framework following a Systems Engineering Process (SEP), and includes a Concept of Operations (ConOps), System Requirements (Functional Requirements), System Design Details, and a Needs to Requirements Traceability Matrix (NRTM). These elements enable users to identify and procure connected intersection solutions that satisfy their specific needs. The companion documents elaborate on specialized areas such as SPaT, MAP, security, and testing and validation, providing requirements and design details tailored for those subject areas. Figure 1 depicts the relationships among these subdocuments and other documents that support the implementation of a connected intersection. By separating out these focused topics, the guide more effectively supports Infrastructure Owner Operators (IOOs), OEMs, suppliers, and application developers who need targeted information. Taken together, the main guide and the companion documents ensure that connected intersection deployments align with national standards and support a high level of interoperability, ultimately facilitating safer and more efficient automated transportation systems. This Testing and Validation Guidance Document focuses on providing guidance on developing a verification plan to confirm that an implementation fulfills all the requirements for a connected signalized intersection. This document defines what should be included in, and examples of content that should go into a verification plan. For IOOs, this document provides actionable guidance on developing test documents to verify an implementation for interoperability. The contents of this document are NOT standardized test methods, test cases, or test procedures; instead, the contents are EXAMPLES of what might be in a verification plan. The specific test approach, test scope, test cases, and test procedures in a verification plan will vary by IOO based on its specific test approach, procedures, and policies. For OEMs and developers, how an IOO will verify an implementation such that the connected vehicle messages broadcasted from compliant intersections enables the development of standards-based safety-critical applications such as Red Light Violation Warning (RLVW). Users are encouraged to refer to the main CTI 4501 document for overarching ConOps, system needs, and operational context while leveraging this Testing and Validation guide for verification and validation activities. Other companion documents, such as CTI 4501/1 - SPaT Messages and CTI 4501/2 - MAP Messages, also contain content about connected intersection testing in Section 8. However, CTI45014 provides the overview and philosophy of developing a testing framework in Section 8, while the companion documents provide topic specific examples.

J3233_202609 (Current)

9/21/2026

This SAE Recommended Practice establishes harmonized test methods for measuring volatile organic compound (VOC) emissions from polyurethane foam materials used in automotive interior applications. This recommended practice complements SAE J2989 by providing standardized emission collection methods, analytical procedures, and reporting formats to ensure consistent and comparable results across different testing laboratories and organizations. The methods discussed in this recommended practice include micro-scale chambers, small-scale chambers, bag methods, thermal extraction techniques, and bottle methods for aldehyde determination. This standard addresses the unique challenges presented by polyurethane foam materials, including their high surface area, absorption capacity, and sensitivity to environmental conditions. The selection of the appropriate test method shall be primarily determined by customer requirements or OEM specifications, as these requirements often dictate the specific test protocol needed for material approval or compliance. When customer requirements are not specified, the selected method should be based on available laboratory capabilities, sample size constraints, testing timeline requirements, and the intended use of the results. This recommended practice provides guidance on the appropriate conditions and limitations for each method to ensure consistent and comparable results across different testing approaches. The standardization of these testing methodologies is essential for reducing the variability currently observed across the automotive industry. By providing clear guidance on specimen preparation, test conditions, analytical procedures, and reporting formats, this standard aims to facilitate meaningful comparison of results, reduce testing costs, and improve product development and quality control efforts. This recommended practice applies to both molded polyurethane foam components such as seating cushions and backrests, and slab stock foam materials used in automotive interior applications.

Taxonomy and Definitions for Terms Related to Driving Automation Systems for On-Road Motor Vehicles

J3016_202609 (Current)

9/20/2026

This document describes [motor] vehicle driving automation systems that perform part or all of the dynamic driving task (DDT) on a sustained basis. It provides a taxonomy with detailed definitions for levels of driving automation, ranging from no driving automation (Level 0) to automated driving under all conditions in which humans can drive, with human driving not needed (Level 5), in the context of [motor] vehicles (hereafter also referred to as “vehicle” or “vehicles”) and their operation on roadways: Level 0: No driving automation Level 1: Driver support for steering OR speed, with continual driver supervision necessary and driver intervention when needed Level 2: Driver support for steering AND speed, with continual driver supervision necessary and driver intervention when needed Level 3: Automated driving under defined conditions, with human driving needed following an alert or evident vehicle malfunction Level 4: Automated driving under defined conditions, with human driving not needed to mitigate risk Level 5: Automated driving under all conditions in which humans can drive, with human driving not needed. The simple level descriptors have been changed to improve understanding of the differences among levels, but these are NOT the definitions of the levels of driving automation. See the definitions of each automation level in Sections 4 and 5 for explanation of these changes. These level definitions, along with additional supporting terms and definitions provided herein, can be used to describe the full range of driving automation features equipped on [motor] vehicles in a functionally consistent and coherent manner. “On-road” refers to publicly accessible roadways (including parking areas and private campuses that permit public access) that collectively serve all road users, including cyclists, pedestrians, and users of vehicles with and without driving automation features. The levels apply to the driving automation feature(s) that are engaged in any given instance of on-road operation of an equipped vehicle. As such, although a given vehicle may be equipped with a driving automation system that is capable of delivering multiple driving automation features that perform at different levels, the level of driving automation exhibited in any given instance is determined by the feature(s) that are engaged. This document also refers to three primary actors in driving: the (human) user, the driving automation system, and other vehicle systems and components. These other vehicle systems and components (or the vehicle in general terms) do not include the driving automation system in this model, even though as a practical matter a driving automation system may actually share hardware and software components with other vehicle systems, such as a processing module(s) or operating code. The levels of driving automation are defined by reference to the specific role played by each of the three primary actors in performance of the DDT and/or DDT fallback. “Role” in this context refers to the expected role of a given primary actor, based on the design of the driving automation system in question and not necessarily to the actual performance of a given primary actor. For example, a driver who fails to monitor the roadway during engagement of a Level 1 adaptive cruise control (ACC) system still has the role of driver, even while they are neglecting it. Active safety systems, such as electronic stability control (ESC) and automatic emergency braking (AEB), and certain types of driver assistance systems, such as lane keeping assistance (LKA), are excluded from the scope of this driving automation taxonomy because they do not perform part or all of the DDT on a sustained basis, but rather provide momentary intervention during potentially hazardous situations. Due to the momentary nature of the actions of active safety systems, their intervention does not change or eliminate the role of the driver in performing part or all of the DDT, and thus are not considered to be driving automation, even though they perform automated functions. In addition, systems that inform, alert, or warn the driver about hazards in the driving environment are also outside the scope of this driving automation taxonomy, as they neither automate part or all of the DDT, nor change the driver’s role in performance of the DDT (see 8.13). It should be noted, however, that crash avoidance features, including intervention-type active safety systems, may be included in vehicles equipped with driving automation systems at any level. For automated driving system (ADS) features (i.e., Levels 3 to 5) that perform the entire DDT, crash mitigation and avoidance capability is part of ADS functionality (see also 8.13). Note that this document provides a taxonomy and definitions and is not a safety standard. The document is not intended to provide guidance for safe vehicle operation by the driving automation system.

Misfire Generator Functional Requirements

J2901_202609 (Current)

9/14/2026

The intent of the specification is to present a functional set of requirements which define the user and hardware interfaces while providing sufficient capability to meet the misfire patterns for compliance demonstration and engineering development. Throughout this requirement, any reference to “ignition or injector control signal” is used interchangeably to infer that the effected spark ignition engine’s ignition control signal or the compression ignition engine’s injector control signal is interrupted, timing phased, or directly passed by the misfire generator. For spark ignition engines, the misfire generator behaves as a spark-defeat device which induces misfires by inhibiting normal ignition coil discharge. It does so by monitoring the vehicle’s ignition timing signals and suspends ignition coil saturation for selected cylinder firing events. The misfire generator will thereby induce engine misfire in spark ignited gasoline internal combustion engines; including rotary engines. For compression ignition engines, the misfire generator behaves as a fuel injection-defeat device which induces misfire by inhibiting the normal fuel injection pulses. It does so by monitoring the injection pulses signal and suspending the injection pulses for selected cylinder firing events. The misfire generator will thereby induce engine misfire in compression ignition engines. This requirement assumes that the user has a fundamental understanding of misfire diagnostics as well as ignition controls. This requirement is not intended to be an introductory misfire guideline or interpretation of regulatory requirements.

Gaining Approval for Seats with Integrated Electronics in Accordance with AC 21-49 Section 7.b

ARP6448C (Current)

8/10/2026

This SAE Aerospace Recommended Practice (ARP) provides a framework for establishing methods and stakeholder responsibilities to ensure that seats with integrated electronic components (e.g., actuation system, reading light, inflatable restraint, in-flight entertainment equipment, etc.) meet the seat technical standard order (TSO) minimum performance standards (MPS). These agreements will allow seat suppliers to build and ship TSO-approved seats with integrated electronic components. The document presents the roles and accountabilities of the electronics manufacturer (EM), the seat supplier, and the TC/ATC/STC applicant/holder in the context of AC 21-49, Section 7.b (“Type Certification Using TSO-Approved Seat with Electronic Components Defined in TSO Design”). This document applies to all FAA seat TSOs C39( ), C127( ), etc. The document defines the roles and responsibilities of each party involved in the procurement of electronics, their integration on a TSO-approved seat, and the seat’s installation on an aircraft. Requirements for design and quality control and the methods for communicating design and change data between EMs and seat suppliers are defined such that standardization is possible across the industry to ensure continued airworthiness of TSO-approved seats with integrated electronic components. This document primarily focuses on correspondence between the seat supplier and the EM. Appendix A: Presents key characteristics of electronic components and guidance on how changes are classified per the requirements of Table 1 of AC 21-49. Appendix B: Provides an outline of a typical data approval process and the change management process between EMs and seat suppliers. Appendix C: While the responsibility rests solely with the seat supplier to ensure all TSO attributes identified in Table 1 of AC 21-49 are acceptable, Appendix C has been included to outline the process for delegating EMs authorization to assess the impact of changes on their equipment with respect to seat TSO attributes. This authorization will allow the classification of the change and the appropriate administration of the change by the EM via seat supplier delegation. Appendix D: Given the mix of business arrangements that can exist in the seat, in-flight, and aircraft procurement life cycle (buyer-furnished equipment, supplier-furnished equipment, customer-furnished equipment), there is discussion on the potential need for separate agreements between the EMs and seat suppliers to ensure binding flow down of design and quality control requirements. As such, a working together agreement (WTA) template is provided as Appendix D.

A Standardized Approach to On-Board Diagnostic (OBD) System Signal Classification and Dependency Analysis

HRCS-PRP0001 (Current)8/7/2026

Part of the legislated on-board diagnostic (OBD) certification process is focused on identifying and documenting serial data signals that are relevant from a legislated OBD perspective. OBD regulations and documentation required for vehicle certification today are becoming increasingly complex. The reason is that increasing numbers of electronic control units (ECUs) are being introduced that communicate with each other. Most of these ECUs are much more powerful in terms of computational power, enabling the implementation of much more functionality on a single ECU. Most of that new functionality is being developed in software. Where previously hard-wired sensors were dominating, nowadays software components take over interpreting and enhancing sensor inputs. This recommended practice (RP) describes a standardized approach to meet these requirements for such increasingly complex environments. Specifically, this RP outlines how to create a serial data signal input/output (I/O) disclosure list to identify, trace, and categorize serial data signals that are relevant to certification. Furthermore, this RP defines a standardized data exchange format that original equipment manufacturers (OEMs) and suppliers can use to exchange related information. In addition to the vehicle certification context, we see a benefit in applying the described methodologies in other contexts, such as the usage of serial data signals within non-emissions-related and/or safety-critical systems. A presentation shared during the 2026 SAE On-Board Diagnostics Symposium-Americas Conference provides a preview and brief summary of the recommended practice and can be freely downloaded (view the PDF presentation).

Plain Bearing Test Methods

ARP5448C (Current)

8/3/2026

This SAE Aerospace Recommended Practice (ARP) establishes methods for testing airframe plain bearings. The purpose of ARP5448 and its associated slash sheets is to document test methods commonly used to evaluate airframe bearings. These test methods may be referenced in specifications, part standards, purchase orders, etc., when the test is deemed appropriate to the intended use of the bearing by the end user of the bearing. These test methods are not intended to encompass every conceivable requirement for an airframe bearing. The end user of the bearing must exercise engineering judgment to determine the most appropriate standard and/or nonstandard tests for the application.

Vehicle OBD II Compliance Test Cases for SAE J1979-2/J1979-3

J1699/5_202607 (Current)

7/23/2026

The primary objective of this recommended practice is to confirm that vehicles can communicate a minimum set of information in accordance with diagnostic test services specified in SAE J1979-2, or the equivalent ISO 14229-1:2013 (Ed. 2) and SAE J1979-3 documents. A successful result using the SAE J1699-5 Automotive Alliance for Innovation (AAI) software for OBD-II testing indicates that the main aspects of UDS communication have been examined, but it does not provide assurance of complete compliance with all aspects of SAE J1979-2 or SAE J1979-3. SAE J1699-5 tests run with a SAE J2534 device hardware and API that is not fully compliant will result in a test failure. This specification takes precedence over all conflicts in the documents cited in this section.
