Connected Vehicle Roadside Equipment --> ITS Roadway Payment Equipment:
vehicle occupancy

Definitions

vehicle occupancy (Information Flow): The number of occupants in a vehicle.

Connected Vehicle Roadside Equipment (Source Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.

ITS Roadway Payment Equipment (Destination Physical Object): 'ITS Roadway Payment Equipment' represents the roadway components of a toll collection system. It provides the capability for vehicle operators to pay tolls without stopping their vehicles. It supports use of locally determined pricing structures and includes the capability to implement various variable pricing policies. Typically, transactions are accompanied by feedback to the customer and a record of the transactions is provided to a back office system (e.g., the Payment Administration Center).

Communication Solutions

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) - OASIS AMQP

Solution Description

This solution is used within the E.U. and the U.S.. It combines standards associated with (None-Data) with those for OASIS AMQP. The (None-Data) standards include an unspecified set of standards at the upper layers. The OASIS AMQP standards include lower-layer standards that support data distribution of specific types of data.

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.

Basis This is all directly observable data. This information is used to help with incident detection. It should be verified to ensure that it is not incorrectly influencing this. This information is used as supplemental information. It should operate correctly if not every single message is received.
