Information Flow Definitions

reversible lane control (Planned) Selected Comm Solution

Control of automated reversible lane configuration and driver information systems.

reversible lane status (Planned) Selected Comm Solution

Current reversible lane status including traffic sensor and surveillance data and the operational status and mode of the reversible lane control equipment.

roadway dynamic signage data (Existing) Selected Comm Solution

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) Selected Comm Solution

Current operating status of dynamic message signs.

signal control commands (Existing) Selected Comm Solution

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

signal control status (Existing) Selected Comm Solution

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

traffic detector data (Existing) Selected Comm Solution

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 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.
