Connected Vehicle Roadside Equipment --> Personal Information Device:
local traveler information
Definitions
local traveler information (Information Flow): Traveler information including traffic, road, and weather conditions for a particular locality. This flow includes the location-specific traveler information and time effectivity of the information.
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.
Personal Information Device (Destination 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.

Basis | This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. | Some minimal guarantee of data integrity is necessary for all C-ITS flows. Flaws in this information will have a minimal effect on systems receiving it. All of the information can be verified through other means, and in a worst case scenario will only cause slightly increased traffic in the general proximity of the RSE. | All of the information provided through this flow will be available from other sources and no systems will directly rely upon it. |
