Architecture Flow Definitions

current asset restrictions   (Future)   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.

 

flood warning_ud   (Future)   No Applicable ITS Standards

Flood warning information. E.g., water having reached high levels in a low water crossing zone, or flooding.

 

maint and constr resource request   (Future)   Applicable ITS Standards

Request for road maintenance and construction resources that can be used in the diversion of traffic (cones, portable signs), clearance of a road hazard, repair of ancillary damage, or any other incident response.

 

maint and constr resource response   (Future)   Applicable ITS Standards

Current status of maintenance and construction resources including availability and deployment status.

 

maint and constr work plans   (Future)   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_ud   (Future)   No Applicable ITS Standards

Current and forecasted traffic information, road and weather conditions, incident information, and other road network status. Either raw data, processed data, or some combination of both may be provided by this architecture flow.

 

road weather information   (Future)   Applicable ITS Standards

Road conditions and weather information that are made available by road maintenance operations to other transportation system operators.

 

roadway maintenance status   (Future)   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 information coordination   (Future)   Applicable ITS Standards

Traffic information exchanged between TMC’s. Normally would include incidents, congestion data, traffic data, signal timing plans, and real-time signal control information.

 

work zone information   (Future)   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.
