Information Flow Definitions
lane management control (Planned)
Information used to configure and control dynamic lane management systems.
lane management information (Planned)
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.
mixed use safety warning control (Planned)
Configuration and control of equipment that monitors and manages mixed use crossings and provides visual displays and warnings to drivers when non–motorized users are occupying a cross walk or other mixed use path crossing.
mixed use safety warning status (Planned)
Current operational status and state of pedestrian crossings and other mixed use path crossing warning systems.
roadway advisory radio data (Existing)
Information used to initialize, configure, and control roadside highway advisory radio. 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 advisory radio status (Existing)
Current operating status of highway advisory radios.
roadway dynamic signage data (Existing)
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 devices.
roadway dynamic signage status (Existing)
Current operating status of dynamic message signs.
shoulder management control (Planned)
Information used to configure and control systems that allow use of a shoulder as a lane for vehicular traffic.
shoulder management information (Planned)
System status including current operational state, violations and logged information.
traffic detector control (Existing)
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (Existing)
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 image meta data (Existing)
Meta data that describes traffic images. Traffic images (video) are in another flow.
traffic images (Existing)
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. Meta data that describes the images is contained in another flow.
traffic metering control (Existing)
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)
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)
Information used to configure and control video surveillance systems.
