This solution is used within Canada and the U.S.. It combines standards associated with US: WZDx with those for I–I: Guaranteed Secure Internet (ITS). The US: WZDx standards include upper–layer standards required to implement work zone information data exchanges. The I–I: Guaranteed Secure Internet (ITS) standards include lower–layer standards that support secure communications with guaranteed delivery between ITS equipment using X.509 or IEEE 1609.2 security certificates.

|---|
| Mgmt | IETF RFC 3415 | View–based Access Control Model (VACM) for the Simple Network Management Protocol (SNMP) | This standard (RFC) contains a MIB that supports the configuration and management of the View–based access control model of SNMP. |
|---|
| Mgmt | IETF RFC 3416 | Version 2 of the Protocol Operations for the Simple Network Management Protocol (SNMP) | This standard (RFC) defines the message structure and protocol operations used by SNMPv3. |
|---|
| Mgmt | IETF RFC 3418 | Management Information Base (MIB) for the Simple Network Management Protocol (SNMP) | This standard (RFC) defines the MIB to configure and manage an SNMP entity. |
|---|

|---|
| Security | IETF RFC 5280 | Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile | This standard (RFC) defines how to use X.509 certificates for secure communications over the Internet. |
|---|
| Security | IETF RFC 8446 | The Transport Layer Security (TLS) Protocol | This standard (RFC) specifies Version 1.3 of the Transport Layer Security (TLS) protocol. The TLS protocol provides communications security over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. |
|---|
| ITS Application Entity | WZDx | Work Zone Data Exchange | This standard defines a common format for exchanging work zone information. |
|---|
| Facilities | IETF RFC 9110 | HTTP Semantics | The Hypertext Transfer Protocol (HTTP) is a stateless application–level protocol for distributed, collaborative, hypertext information systems. This document describes the overall architecture of HTTP, establishes common terminology, and defines aspects of the protocol that are shared by all versions. In this definition are core protocol elements, extensibility mechanisms, and the "http" and "https" Uniform Resource Identifier (URI) schemes. |
|---|
| Facilities | IETF RFC 9112 | HTTP/1.1 | The Hypertext Transfer Protocol (HTTP) is a stateless application–level protocol for distributed, collaborative, hypertext information systems. This document specifies the HTTP/1.1 message syntax, message parsing, connection management, and related security concerns. |
|---|
| Facilities | IETF RFC 7159 | The JavaScript Object Notation (JSON) Data Interchange Format | The JavaScript Object Notation (JSON), a lightweight, text–based, language–independent data interchange format. It was derived from the ECMAScript Programming Language Standard. JSON defines a small set of formatting rules for the portable representation of structured data. This document removes inconsistencies with other specifications of JSON, repairs specification errors, and offers experience–based interoperability guidance. |
|---|
| TransNet | IETF RFC 4291 | IP Version 6 Addressing Architecture | This standard (RFC) defines the addressing architecture of the IP Version 6 (IPv6) protocol. It includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node's required addresses. |
|---|
| TransNet | IETF RFC 4443 | Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification | This standard (RFC) defines the control messages to manage IPv6. |
|---|
| TransNet | IETF RFC 8200 | Internet Protocol, Version 6 | This document specifies version 6 of the Internet Protocol (IPv6). |
|---|
| TransNet | IETF RFC 9293 | Transmission Control Protocol | This document specifies the Transmission Control Protocol (TCP). TCP is an important transport–layer protocol in the Internet protocol stack, and it has continuously evolved over decades of use and growth of the Internet. Over this time, a number of changes have been made to TCP as it was specified in RFC 793, though these have only been documented in a piecemeal fashion. This document collects and brings those changes together with the protocol specification from RFC 793. This document obsoletes RFC 793, as well as RFCs 879, 2873, 6093, 6429, 6528, and 6691 that updated parts of RFC 793. It updates RFCs 1011 and 1122, and it should be considered as a replacement for the portions of those documents dealing with TCP requirements. It also updates RFC 5961 by adding a small clarification in reset handling while in the SYN–RECEIVED state. The TCP header control bits from RFC 793 have also been updated based on RFC 3168. |

Two significant or one significant and several minor issues. For existing deployments, the chosen solution is likely deficient in security or management capabilities and the issues should be reviewed and upgrades developed as needed. For new deployments, the solution may be viable for pilots when applied to the triples it supports; such pilot deployments should consider a path to addressing these issues as a part of their design activities. The solution does not provide sufficient interoperability, management, and security to enable proper, full–scale deployment without additional work.
