This solution is used within the U.S.. It combines standards associated with US: GTFS with those for I-I: Secure Internet (ITS). The US: GTFS standards include upper-layer standards required to implement public, transit-related communications. The I-I: Secure Internet (ITS) standards include lower-layer standards that support secure communications 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 | GTFS Realtime | General Transit Feed Specification Realtime | This document defines a feed specification that allows public transportation agencies to provide real-time updates about their fleet to application developers. It is an extension to GTFS (General Transit Feed Specification), an open data format for public transportation schedules and associated geographic information. GTFS Realtime was designed around ease of implementation, good GTFS interoperability and a focus on passenger information. |
| ITS Application Entity | GTFS | General Transit Feed Specification | This document defines a common (open data) format for exchanging public transportation schedules and associated geographic information. |
| Facilities | IETF RFC 7230 | Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing | This standard (RFC) defines the main Application Layer protocol used for the world-wide web. |
| Facilities | ISO 21320-1 | Information technology — Document Container File — Part 1: Core | ISO/IEC 21320-1 specifies the core requirements for 1) document container files, and 2) implementations that produce and/or consume document container files. It normatively references the Zip File Format Specification version 6.3.3 of PKWARE(R) Inc. Document container files are conforming Zip files as specified by that document. |
| Facilities | IETF RFC 4180 | Common Format and MIME Type for Comma-Separated Values (CSV) Files | This standard (RFC) documents the format used for Comma-Separated Values (CSV) files and registers the associated MIME type "text/csv". |
| TransNet | IETF RFC 2460 | Internet Protocol, Version 6 (IPv6) Specification | This standard (RFC) specifies version 6 of the Internet Protocol (IPv6), also sometimes referred to as IP Next Generation or IPng. |
| 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 793 | Transmission Control Protocol | This standard (RFC) defines the main connection-oriented Transport Layer protocol used on Internet-based networks. |
| Access | Internet Subnet Alternatives | A set of alternative standards that includes any Subnet Layer method of connecting to the Internet. |
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.
