ITS Roadway Payment Equipment --> Roadside Equipment:
vehicle entries and exits

This triple is bi-directional. See also Roadside Equipment --> ITS Roadway Payment Equipment: vehicle entries and exits


vehicle entries and exits (Information Flow): Information exchanged between an RSE and ITS Roadway Equipment that supports detection of non-equipped vehicles in an automated lane, low emissions zone, or other facility where V2I communications is used to monitor vehicles at entry or exit points. This exchange also supports identification of non-equipped vehicles where an RSE is used for payment collection. This generic exchange can be implemented by any approach that compares vehicle detections with V2I communications by the RSE to identify vehicles that are not equipped or are otherwise unable to communicate with the RSE.

ITS Roadway Payment Equipment (Source 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).

Roadside Equipment (Destination Physical Object): 'Roadside Equipment' (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.
