Interface: SDDOT Region and Area Construction and Maintenance Office To SDDOT Road and Weather Information System

maint and constr resource request   (Planned)  

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   (Planned)  

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

 

maint and constr work plans   (Planned)  

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.

 

request for road network conditions   (Planned)  

Request for traffic information, road conditions, surface weather conditions, incident information, and other road network status. The request specifies the region/route of interest, the desired effective time period, and other parameters that allow preparation of a tailored response. The request can be a subscription that initiates as-needed information updates as well as a one-time request for information.

 

road network conditions   (Planned)  

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   (Planned)  

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

 

roadway maintenance status   (Planned)  

Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).

 

traffic images_ud   (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.

 

traffic information coordination   (Planned)  

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   (Planned)  

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.
