Connected Vehicle Roadside Equipment --> Personal Information Device:
arriving train information
Definitions
arriving train information (Information Flow): Information for a train approaching a highway-rail intersection that may include direction and allow calculation of approximate arrival time and closure duration.
Connected Vehicle Roadside Equipment (Source Physical Object): 'Connected Vehicle Roadside Equipment' (CV 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.
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.

Basis | Trains arriving should be visible, viewable and certainly not concealed. | This flow forms the basis for providing data that, if incorrect, could lead to a catastrophic mistake. | This flow forms the basis for providing data that, if incorrect, could lead to a catastrophic mistake. Since this flow can lead to other actions with other effects, HIGH is justifiable. |
