personal location Quintuple

Bidirectional?: False

personal location (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'Personal Pedestrian Safety', and 'RSE Transit User Guidance'. In this case, there is only a single Layer 2 flow associated with this interconnect, so the Layer 1 application interconnect name and the Layer 2 information flow name are both 'personal location'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Personal Information Device' to 'Roadside Equipment'.

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 connected vehicle on-board equipment.

Personal Pedestrian Safety (Source Application Object): The "Personal Pedestrian Safety" application improves pedestrian safety by providing pedestrian location information to the infrastructure that can be used to avoid collisions involving pedestrians. The application may also alert the pedestrian of unsafe conditions, augmenting or extending information provided by signals and signs. The information provided and the user interface delivery mechanism (visual, audible, or haptic) can also be tailored to the needs of the user that is carrying or wearing the device that hosts the application.

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.

RSE Transit User Guidance (Destination Application Object): "RSE Transit User Guidance" uses short range communications to provide terminal or stop-specific guidance to transit user devices that assists users in finding the right stop and the right bus. Optionally, this object can collect the transit user location and planned itinerary so that tailored guidance can be provided.
