Pedestrian --> Personal Information Device:
personal input
Definitions
personal input (Information Flow): User input to a personal device. This flow may request traveler information, request right of way, summon assistance, make a reservation, or request any other traveler service. This flow also establishes the settings that tailor each application to suit the user's needs.
Pedestrian (Source 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
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.

| 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 | Personal input similar to pressing the button on a pedestrian call at a stop light, nothing that could not be otherwise observed. | This data does have to be correct, so the signal receives the pedestrian call. Given that the pedestrian should still not enter the intersection without feedback, this could be considered LOW. | There are generally other ways to accomplish this flow. Depending on the pedestrian this might be MODERATE, for example for pedestrians unable to easily access the call button. | |
