Architecture Flow Definitions

environmental sensor data  (Future)  Applicable ITS Standards

Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.

environmental sensors control  (Future)  Applicable ITS Standards

Data used to configure and control environmental sensors.

roadway dynamic signage data  (Future)  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  (Future)  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 fault data  (Future)  Applicable ITS Standards

Faults reported by traffic signal control equipment.

traffic detector control  (Future)  Applicable ITS Standards

Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.

traffic detector data  (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 sensor system.

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. This flow includes the images and meta data that describes the images.

video surveillance control  (Future)  Applicable ITS Standards

Information used to configure and control video surveillance systems.
