Architecture Flow Definitions

roadway dynamic signage data  (Existing)  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  (Medium-term)  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.

signal control commands  (Existing)  Applicable ITS Standards

Control of traffic signal controllers or field masters including clock synchronization.

signal control device configuration  (Existing)  Applicable ITS Standards

Data used to configure traffic signal control equipment including local controllers and system masters.

signal control plans  (Existing)  Applicable ITS Standards

Traffic signal timing parameters including minimum green time and interval durations for basic operation and cycle length, splits, offset, phase sequence, etc. for coordinated systems.

signal control status  (Existing)  Applicable ITS Standards

Operational and status data of traffic signal control equipment including operating condition and current indications.

signal fault data  (Existing)  Applicable ITS Standards

Faults reported by traffic signal control equipment.

signal system configuration  (Existing)  Applicable ITS Standards

Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).

traffic detector data  (Existing)  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.

traffic images  (Existing)  Applicable ITS Standards

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 meta data that describes the images.

video surveillance control  (Existing)  Applicable ITS Standards

Information used to configure and control video surveillance systems.
