Information Flow Definitions

lane management control (Planned) Selected Comm Solution

Information used to configure and control dynamic lane management systems.

lane management information (Planned) 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 (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.

signal control commands (Planned) Selected Comm Solution

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

signal control device configuration (Planned) Selected Comm Solution

Data used to configure traffic signal control equipment including local controllers and system masters.

signal control plans (Planned) Selected Comm Solution

Traffic signal timing parameters including minimum green time and interval durations for basic operation and cycle length, splits, offset, phase sequence, etc. for coordinated systems.

signal control status (Planned) Selected Comm Solution

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

signal fault data (Planned) Selected Comm Solution

Faults reported by traffic signal control equipment.

signal system configuration (Planned) Selected Comm Solution

Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).

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
