Information Flow Definitions
lane management control (Existing) Selected Comm Solution
Information used to configure and control dynamic lane management systems.
lane management information (Existing) Selected Comm Solution
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.
reversible lane control (Existing) Selected Comm Solution
Control of automated reversible lane configuration and driver information systems.
reversible lane status (Existing) 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 (Future) 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 (Future) Selected Comm Solution
Current operating status of dynamic message signs.
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 (Future) 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 (Future)
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.
video surveillance control (Future) Selected Comm Solution
Information used to configure and control video surveillance systems.
