Architecture Flow Definitions
amber and silver alert_ud (Existing/Planned)
Amber alert information to be placed on dynamic message signs controlled by a traffic management element or on the emergency alert system (EAS).
current infrastructure restrictions (Planned) Applicable ITS Standards
Restrictions levied on transportation asset usage based on infrastructure design, surveys, tests, or analyses. This includes standard facility design height, width, and weight restrictions, special restrictions such as spring weight restrictions, and temporary facility restrictions that are imposed during maintenance and construction.
incident information for public (Existing/Planned) Applicable ITS Standards
Report of current desensitized incident information prepared for public dissemination.
maint and constr work plans (Planned) Applicable ITS Standards
Future construction and maintenance work schedules and activities including anticipated closures with anticipated impact to the roadway, alternate routes, anticipated delays, closure times, and durations.
road network conditions (Existing) Applicable ITS Standards
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.
roadway maintenance status (Planned) Applicable ITS Standards
Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).
traffic control information (Existing/Planned) Applicable ITS Standards
Represents the flow of traffic control and status information from a TMC to a third party TIC. This is reporting only, not actual control.
traffic images (Existing/Planned) Applicable ITS Standards
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 and meta data that describes the images.
traffic images. (Existing/Planned)
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 and the operational status of the surveillance system.
work zone information (Planned) Applicable ITS Standards
Summary of maintenance and construction work zone activities affecting the road network including the nature of the maintenance or construction activity, location, impact to the roadway, expected time(s) and duration of impact, anticipated delays, alternate routes, and suggested speed limits. This information may be augmented with images that provide a visual indication of current work zone status and traffic impacts.
