Personal Information Device --> Roadside Equipment:
connected vehicle data

Definitions

connected vehicle data (Information Flow): This flow represents any secure data exchange within the Connected Vehicle Environment. It defines the common data fields that are shared by all secure messages, including a verifiable timestamp, a verifiable geographic location of the sender's origin, and a digital signature. The information may also be encrypted to protect sensitive data content.

Personal Information Device (Source Physical Object): The "Personal Information Device" provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. It provides travelers with the capability to receive route planning from the infrastructure at home, at work, or en route using personal devices that may be linked with connected vehicle on-board equipment.

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). Communications with adjacent ITS Roadway Equipment (see the separate object) 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 roadside equipment, and centers that provide back office support.
