Architecture Flow Definitions

field device status  (Existing)  Applicable ITS Standards

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

roadway information system data  (Existing)  Applicable ITS Standards

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.

roadway information system status  (Existing)  Applicable ITS Standards

Current operating status of dynamic message signs, highway advisory radios, beacon systems, or other configurable field equipment that provides dynamic information to the driver.

roadway treatment system control  (Future)  Applicable ITS Standards

Control data for remotely located, automated devices, that affect the roadway surface (e.g. de-icing applications).

roadway treatment system status  (Future)  Applicable ITS Standards

Current operational status of automated roadway treatment devices (e.g., anti-icing systems).

traffic flow  (Future)  Applicable ITS Standards

Raw and/or processed traffic detector data which allows derivation of traffic flow variables (e.g., speed, volume, and density measures) and associated information (e.g., congestion, potential incidents). This flow includes the traffic data and the operational status of the traffic detectors.

traffic images  (Future)  Applicable ITS Standards

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

video surveillance control  (Future)  Applicable ITS Standards

Information used to configure and control video surveillance systems.

work zone warning device control  (Future)  Applicable ITS Standards

Data used to configure and control work zone safety monitoring and warning devices.

work zone warning status  (Future)  Applicable ITS Standards

Status of a work zone safety monitoring and warning devices. This flow documents system activations and includes additional supporting information (e.g., an image) that allows verification of the alarm.
