US: TCIP - Secure Wireless Internet (ITS)

Description

This solution is used within the U.S.. It combines standards associated with US: TCIP with those for I–M: Secure Wireless Internet (ITS). The US: TCIP standards include upper–layer standards required to implement transit–related communications. The I–M: Secure Wireless Internet (ITS) standards include lower–layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 or IEEE 1609.2 certificates. A non–mobile (if any) endpoint may connect to the service provider using any Internet connection method.

Includes Standards

Level	DocNum	FullName	Description
ITS Application Entity	APTA TCIP–S–001 Vol 2	Transit Communications Interface Profiles – TCIP Data and Dialog Definitions	This standard defines the data concepts used by the TCIP standard.
Facilities	APTA TCIP–S–001 Vol 2	Transit Communications Interface Profiles – TCIP Data and Dialog Definitions	This standard defines the data concepts used by the TCIP standard.

Readiness: Moderate–Low

Readiness Description

Multiple significant and 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. Some solutions in this category may also be becoming obsolete from an interoperability perspective and if this is the case, then upgrades should be planned as soon as possible. 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.
