US: GTFS - Secure Internet (ITS)

Description

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.

Includes Standards

Level	DocNum	FullName	Description
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".
Access		Internet Subnet Alternatives	A set of alternative standards that includes any Subnet Layer method of connecting to the Internet.

Readiness: Moderate

Readiness Description

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.
