personal updates

Definitions

personal updates (Information Flow): Personal information, alerts, and warnings provided to pedestrians, 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 connected vehicle on-board equipment.

Emergency Personnel (Destination Physical Object): 'Emergency Personnel' represents personnel that are responsible for police, fire, emergency medical services, towing, service patrols, and other special response team (e.g., hazardous material clean-up) activities at an incident site. These personnel are associated with the Emergency Vehicle during dispatch to the incident site, but often work independently of the Emergency Vehicle while providing their incident response services.

This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. A few false warnings should not have a bad consequence. When an emergency personnel receives a warning they can look around and verify whether or not a vehicle is actually headed towards them. However, if the device does not transmit the correct message to the user, they may miss an incoming vehicle warning, and be hit by a vehicle. It would be better to receive any messages than to not have this application available due to availability requirements. However, the higher the availability here, the more useful the application will be and the more emergency personnel can rely on it.
