Architecture Flow Definitions

field equipment status  (Planned)  Applicable ITS Standards

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

roadside archive data  (Planned)  Applicable ITS Standards

A broad set of data derived from roadside sensors that includes current traffic conditions, environmental conditions, and any other data that can be directly collected by roadside sensors. This data also indicates the status of the sensors and reports of any identified sensor faults.

roadway dynamic signage data  (Planned)  Applicable ITS Standards

Information used to initialize, configure, and control dynamic message signs. 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 dynamic signage status  (Planned)  Applicable ITS Standards

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

roadway treatment system status  (Planned)  Applicable ITS Standards

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

traffic detector data  (Planned)  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 sensor system.

variable speed limit status  (Planned)  Applicable ITS Standards

Current operating status of the variable speed limit systems including the state of the equipment.

work zone warning status  (Planned)  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.
