Personal Information Device --> Pedestrian:
personal updates
Definitions
personal updates (Information Flow): Personal information, alerts, and warnings provided to pedestrians, micromobility vehicle (MMV) users, work crew members, and other individuals in a mixed use area. This includes visual, audio, and haptic outputs that may be customized to support individual needs.
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.
Pedestrian (Destination Physical Object): The 'Pedestrian' represents a person traveling on foot. Pedestrians participate in ITS services that support safe, shared use of the transportation network. Included are visually impaired travelers who travel through portions of the transportation network and interact with ITS systems. They provide input (e.g. a call signal requesting right of way at an intersection) and may be detected by ITS services to improve safety

| Interoperability | Description |
|---|---|
| Not Applicable | Interoperability ratings don't apply per se to some types of interfaces like human interfaces. These interfaces may still benefit from associated standards (e.g., ergonomic and human factors standards for human interfaces), but the primary motive for these standards is not interoperability. |

| Basis | This data is informing the pedestrian about the safety of the intersections. It should not contain anything sensitive, and does not matter if another person can observe it. | This is the information that is presented to the individual. If they receive incorrect information, they may act in an unsafe manner. However, there are other indicators that would alert them to any hazards, such as an oncoming vehicle or crossing safety lights. | If this information is not made available to the pedestrian, then the system has not operated correctly. | |
