Akron Regional ITS Architecture (2022)

ODOT Wide Area Information Disseminator System

Status: Future

Description

The 'Wide Area Information Disseminator System' represents the center based systems and communications equipment that is used to send messages to equipped vehicles using wide–area wireless communications such as satellite radio, terrestrial FM broadcast subcarrier, or cellular data networks.

Functional Objects

Functional Object	Description	User Defined
ITS Management Support	'ITS Management Support' provides management of the ITS Object. This includes management of regulatory information and policies, management of application processes, management of communication system configuration and update management, communications interfaces, protocol–specific techniques to ensure interoperability such as service advertisements, communications congestion management and interference management, local device states and communications information, billing management, fault management, service level and performance monitoring.	False
ITS Security Support	'ITS Security Support' provides communications and system security functions to the ITS Object, including privacy protection functions. It may include firewall, intrusion management, authentication, authorization, profile management, identity management, cryptographic key management. It may include a hardware security module and security management information base.	False
WAID Broadcast Services	'WAID Broadcast Services' provides wide–area digital broadcast of traveler information to transportation users across a region. It collects traveler information of interest to clientele (either subscribers or the general public) and distributes the traveler information using broadcast data services that are offered in context with entertainment and other data services.	False

Physical Standards

Document Number	Title	Description
ISO 21217	Intelligent transport systems –– Communications access for land mobiles (CALM) –– Architecture	ISO 21217 describes the communications reference architecture of nodes called "ITS station units" designed for deployment in ITS communication networks. While it describes a number of ITS station elements, whether or not a particular element is implemented in an ITS station unit depends on the specific communication requirements of the implementation. It also describes the various communication modes for peer–to–peer communications over various networks between ITS communication nodes. These nodes may be ITS station units as described in the document or any other reachable nodes. ISO 21217 specifies the minimum set of normative requirements for a physical instantiation of the ITS station based on the principles of a bounded secured managed domain.
NIST FIPS PUB 140–2	Security Requirements for Cryptographic Modules	This Federal Information Processing Standard (140–2) specifies the security requirements that will be satisfied by a cryptographic module, providing four increasing, qualitative levels intended to cover a wide range of potential applications and environments. The areas covered, related to the secure design and implementation of a cryptographic module, include specification; ports and interfaces; roles, services, and authentication; finite state model; physical security; operational environment; cryptographic key management; electromagnetic interference/electromagnetic compatibility (EMI/EMC); self–tests; design assurance; and mitigation of other attacks.
