Definitions

parking information (Information Flow): General parking information and status, including current parking availability, parking pricing, and parking space availability information.

Parking Management Center (Source Physical Object): The 'Parking Management Center' manages one or more parking lots by providing configuration and control of field infrastructure, user account management and interfaces with financial systems to manage payment. This p-object takes the back office portion of the Parking Management System's functionality as it was defined in ARC-IT 8.3 and prior.

Transportation Information Center (Destination Physical Object): The 'Transportation Information Center' collects, processes, stores, and disseminates transportation information to system operators and the traveling public. The physical object can play several different roles in an integrated ITS. In one role, the TIC provides a data collection, fusing, and repackaging function, collecting information from transportation system operators and redistributing this information to other system operators in the region and other TICs. In this information redistribution role, the TIC provides a bridge between the various transportation systems that produce the information and the other TICs and their subscribers that use the information. The second role of a TIC is focused on delivery of traveler information to subscribers and the public at large. Information provided includes basic advisories, traffic and road conditions, transit schedule information, yellow pages information, ride matching information, and parking information. The TIC is commonly implemented as a website or a web-based application service, but it represents any traveler information distribution service.

Selected Solution

Parking - Secure Internet (ITS)

Solution Description

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with Parking with those for I-I: Secure Internet (ITS). The Parking standards include upper-layer standards required to exchange parking information. 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.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

Interoperability	Description
Regional	Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

Security

Information Flow Security
	Confidentiality	Integrity	Availability
Rating	Moderate	Moderate	Moderate
Basis	Does not include PII, but does include usage information for a managed facility that implies a number of vehicles. While this is observable information, it could be considered competitive, and regardless is accessible without being physically present, which is its own barrier.	Generally transportation coordination information should be correct between source and destination, or inappropriate actions may be taken.	Most likely not a frequently updated flow. Typically MODERATE for applications with a high degree of commercial vehicle parking, but could be LOW otherwise.
