Personal Information Device --> Social Media:
traveler request

Definitions

traveler request (Information Flow): A request for traveler information including traffic, transit, toll, parking, road weather conditions, event, and passenger rail information. The request identifies the type of information, the area of interest, parameters that are used to prioritize or filter the returned information, and sorting preferences.

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.

Social Media (Destination Physical Object): 'Social Media' provides forums for social interaction and opportunities for gathering and distributing traveler information. These sites provide crowd sourced information and the opportunity to provide traveler information to specific communities of interest. Examples include Facebook, Twitter, and LinkedIn. Each social media platform offers its own tools and API that allow integration of web content into a shared social media experience.
