Information Flow Definitions

mixed use safety warning control  (Future)  Selected Comm Solution

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  (Future)  Selected Comm Solution

Current operational status and state of pedestrian crossings and other mixed use path crossing warning systems.

right-of-way request notification  (Existing)  Selected Comm Solution

Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi–modal crossing activation, or other source for right–of–way.

signal control commands  (Existing)  Selected Comm Solution

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

signal control device configuration  (Existing)  Selected Comm Solution

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

signal control plans  (Existing)  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  (Existing)  Selected Comm Solution

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

signal fault data  (Existing)  Selected Comm Solution

Faults reported by traffic signal control equipment.

signal system configuration  (Existing)  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  (Existing)  Selected Comm Solution

Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.

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
