Information Flow Definitions
current infrastructure restrictions (Planned) Selected Comm Solution
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.
equipment maintenance request (Planned) Selected Comm Solution
Identification of field equipment requiring repair and known information about the associated faults.
equipment maintenance status (Planned) Selected Comm Solution
Current status of field equipment maintenance actions.
maint and constr work plans (Planned) Selected Comm Solution
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 (Planned) 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.
roadway maintenance status (Planned) Selected Comm Solution
Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).
special vehicle restricted use information (Planned) Selected Comm Solution
Parameters necessary for implementing unrestricted access to controlled access or toll facilities by special vehicles; e.g., maintenance vehicles, emergency vehicles, etc.
work plan feedback (Planned) Selected Comm Solution
Comments and suggested changes to proposed construction and maintenance work schedules and activities. This information influences work plan schedules so that they minimize impact to other system operations and the overall transportation system.
work zone information (Planned) Selected Comm Solution
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.
