Personal Information Device --> Connected Vehicle Roadside Equipment:
personal signal service request

Definitions

personal signal service request (Information Flow): A request for right of way from a personal device that indicates the type of traveler (pedestrian, special needs pedestrian, bicyclist, etc.), anticipated time of arrival, travel path, and crossing duration.

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 (i.e., Roadside Units (RSUs)) equipped with short range wireless (SRW) communications technology, as well as any other supporting equipment that leverage the RSU and are not described by other objects (e.g., a local roadside processor). CVRSE are used to send messages to, and receive messages from, nearby vehicles and personal devices equipped with compatible communications technology. 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.
