Personal Information Device --> Connected Vehicle Roadside Equipment:
transit user information
Definitions
transit user information (Information Flow): Information about individual transit users boarding a transit vehicle, used to track a user's progress on a scheduled transit trip.
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. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help.
Connected Vehicle Roadside Equipment (Destination 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.

Rating | Moderate | Moderate | Moderate | |
Basis | May contain the PII of the originator, which should be readable only by the intended recepient lest the originator's privacy be violated. If the implementation does not provide traveler identity, this may be reduced to LOW. | If this is compromised or corrupted, the user's needs may not be properly communicated or met. If this is forged, the transit provider may provide unnecessary services. | If this is not available, the user may not receive transit services offered, and as with other transit services may ceases using the system. While the immediate impact is LOW, long term impact is MODERATE due to user confidence issues. |
