archive requests   (Planned)  

A request to a data source for information on available data (i.e. "catalog") or a request that defines the data to be archived. The request can be a general subscription intended to initiate a continuous or regular data stream or a specific request intended to initiate a one-time response from the recipient.

 

archive status   (Planned)  

Notification that data provided to an archive contains erroneous, missing, or suspicious data or verification that the data provided appears valid. If an error has been detected, the offending data and the nature of the potential problem are identified.

 

closure coordination   (Planned)  

Coordination between subsystems regarding construction and maintenance closure times and durations.

 

construction and maintenance archive data   (Planned)  

Information describing road construction and maintenance activities identifying the type of activity, the location of the activity, and the activity status. Content may include a catalog of available information, the actual information to be archived, and associated meta data that describes the archived information.

 

current road restrictions   (Planned)  

Information regarding construction and maintenance activities which reduce the capacity of the roadway to handle large loads, including any changes in allowable vehicle width, height, or weight.

 

equipment maintenance status   (Planned)  

Current status of field equipment maintenance actions.

 

maintenance resource request   (Planned)  

Request for road maintenance resources that can be used in the diversion of traffic (cones, portable signs), clearance of an incident, and repair of ancillary damage.

 

maintenance resource response   (Planned)  

Current status of maintenance resources included availability and deployment status.

 

traffic archive data   (Planned)  

Information describing the use and vehicle composition on transportation facilities and the traffic control strategies employed. Content may include a catalog of available information, the actual information to be archived, and associated meta data that describes the archived information.

 

traffic control coordination   (Planned)  

Information transfers that enable remote monitoring and control of traffic management devices. This flow is intended to allow cooperative access to, and control of, field equipment during incidents and special events and during day-to-day operations. This flow also allows 24-hour centers to monitor and control assets of other centers during off-hours, allows system redundancies and fail-over capabilities to be established, and otherwise enables integrated traffic control strategies in a region.

traffic equipment status   (Planned)  

Identification of field equipment requiring repair and known information about the associated faults.

 

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 status   (Planned)  

Status of maintenance work zone.
