Information Flow Definitions
roadway dynamic signage data (Planned) 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 (Planned) Selected Comm Solution
Current operating status of dynamic message signs.
traffic detector control (Planned) Selected Comm Solution
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (Planned) 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
variable speed limit control (Planned) Selected Comm Solution
Information used to configure and control variable speed limit systems including the equipment used to provide current speed limits and other information to drivers.
variable speed limit status (Planned) Selected Comm Solution
Current operating status of the variable speed limit systems including the state of the equipment.
