Architecture Flow Definitions

environmental sensors control  (Existing)  Applicable ITS Standards

Data used to configure and control environmental sensors.

lane management control  (Planned)  Applicable ITS Standards

Information used to configure and control dynamic lane management systems.

lane management information  (Planned)  Applicable ITS Standards

System status of managed lanes including current operational state, violations, and logged information. This includes lane usage information including both traditional traffic flow measures and special information associated with managed lanes such as measured passenger occupancies. It also includes the operational status of the lane management equipment.

right-of-way request notification  (Existing)  Applicable ITS Standards

Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi–modal crossing activation, or other source for right–of–way.

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  (Existing)  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.

traffic detector control  (Existing)  Applicable ITS Standards

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

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.

traffic metering control  (Existing)  Applicable ITS Standards

Control commands and operating parameters for ramp meters, interchange meters, mainline meters, and other systems equipment associated with roadway metering operations.

traffic metering status  (Existing)  Applicable ITS Standards

Current operational status and operating parameters for ramp meters, interchange meters, mainline meters and other control equipment associated with roadway metering operations.

video surveillance control  (Existing)  Applicable ITS Standards

Information used to configure and control video surveillance systems.
