Information Flow Definitions
alert notification (Existing) Selected Comm Solution
Notification of a major emergency such as a natural or man–made disaster, civil emergency, or child abduction for distribution to the public. The flow identifies the alert originator, the nature of the emergency, the geographic area affected by the emergency, the effective time period, and information and instructions necessary for the public to respond to the alert. This flow may also identify specific information that should not be released to the public.
alert status (Existing) Selected Comm Solution
Information indicating the current status of the emergency alert including identification of the traveler and driver information systems that are being used to provide the alert.
incident information for public (Planned) Selected Comm Solution
Report of current desensitized incident information prepared for public dissemination.
road network conditions (Existing) Selected Comm Solution
Current and forecasted traffic information, road and weather conditions, and other road network status. Either raw data, processed data, or some combination of both may be provided by this flow. Information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements) in effect is included.
road network environmental situation data (Planned) Selected Comm Solution
Aggregated environmental situation data collected from vehicles and other sources for the road network. Aggregated information would include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, ALB status, and other collected vehicle system status and sensor information for the region.
road network traffic situation data (Planned) Selected Comm Solution
Aggregated route usage, travel times, and other aggregated data collected from probe vehicles that can be used to estimate current traffic conditions.
traffic control information (Existing) Selected Comm Solution
Represents the flow of traffic control and status information between centers. This is reporting only, not actual control. This specifically includes the current state of any demand management strategies that have been implemented.
traffic image meta data (Existing) Selected Comm Solution
Meta data that describes traffic images. Traffic images (video) are in another flow.
traffic images (Existing)
High fidelity, real–time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications. This flow includes the images. Meta data that describes the images is contained in another flow.
