Definitions

authorization request (Information Flow): Request to determine if a transportation user is authorized to use a particular transportation resource.

Parking Area Equipment (Source Physical Object): 'Parking Area Equipment' provides electronic monitoring and management of parking facilities. It supports an I2V link to the Vehicle that allows electronic collection of parking fees and monitors and controls parking meters that support conventional parking fee collection. It also includes the instrumentation, signs, and other infrastructure that monitors parking lot usage and provides local information about parking availability and other general parking information. The two primary approaches to monitoring parking area usage are sensing vehicles within parking spots or counting vehicles as they come in and as they leave the area. This portion of the functionality must be located in the parking area where it can monitor, classify, and share information with customers and their vehicles. See also the separate 'Parking Management Center' physical object that may be located in a back office, remote from the parking area, which interfaces with the financial infrastructure and broadly disseminates parking information to other operational centers in the region.

Parking Management Center (Destination 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.

Communication Solutions

(None-Data) - Secure Internet (ITS) (43)

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - Secure Internet (ITS)

Solution Description

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for I-I: Secure Internet (ITS). The (None-Data) standards include an unspecified set of standards at the upper layers. 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
Local	In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides.

Security

Information Flow Security
	Confidentiality	Integrity	Availability
Rating	Moderate	Moderate	Moderate
Basis	Contains an identifier linked to an individual or specific device, and thus PII by definition. Compromise of one secureID would likely impact only one user, but the nature of this flow requires that the same algorithm be used for every user; algorithm compromise would harm every user, which would have widespread impact.	Payment flows must all have some integrity protection and consistent availability to prohibit forgery and instill confidence in the payment process. Repurcussions of roadway payment are individually fairly small, collectiviely significant but probably never catastrophic. Thus MODERATE for both integrity and availability.
