fault reports   (Planned)  

Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.

 

freeway control data   (Planned)  

Control commands and operating parameters for ramp meters, dynamic message signs, mainline metering/lane controls and other systems associated with freeway operations.

 

freeway control status   (Planned)  

Current operational status and operating parameters for ramp meters, dynamic message signs, mainline metering/lane controls and other control equipment associated with freeway operations.

 

incident data   (Planned)  

Data and imagery from the roadside supporting incident detection and verification.

 

roadway information system data   (Planned)  

Information used to initialize, configure, and control roadside systems that provide driver information (e.g., dynamic message signs, highway advisory radio, beacon systems). This flow can provide message content and delivery attributes, local message store maintenance requests, control mode commands, status queries, and all other commands and associated parameters that support remote management of these systems.

 

sensor and surveillance control   (Planned)  

Information used to configure and control sensor and surveillance systems at the roadside.

 

traffic flow   (Planned)  

Raw and/or processed traffic detector information which allows derivation of traffic flow variables (e.g., speed, volume and density measures).

 

traffic images   (Planned)  

High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.

 

vehicle probe data   (Planned)  

Vehicle probe data indicating identity, route segment identity, link time and location.
