Information Flow Definitions
barrier system control (Future) Selected Comm Solution
Information used to configure and control barrier systems that are represented by gates, barriers and other automated or remotely controlled systems used to manage entry to roadways.
barrier system status (Future) Selected Comm Solution
Current operating status of barrier systems. Barrier systems represent gates, barriers and other automated or remotely controlled systems used to manage entry to roadways. Status of the systems includes operating condition and current operational state.
environmental sensor data (Future) Selected Comm Solution
Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.
environmental sensors control (Future) Selected Comm Solution
Data used to configure and control environmental sensors.
field equipment status (Existing) Selected Comm Solution
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
passive vehicle monitoring control (Existing) Selected Comm Solution
Control commands used to control detection systems that rely on infrastructure–based identification of individual vehicles to measure travel times and other related measures by identifying the same vehicle at different points in the network. Related technologies include Bluetooth readers and license plate recognition systems.
passive vehicle monitoring data (Existing) Selected Comm Solution
Time stamped identifiers that identify the vehicles that have passed through a detection zone.
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
traffic image meta data (Existing) Selected Comm Solution
Meta data that describes traffic images. Traffic images (video) are in another flow.
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.
video surveillance control (Existing) Selected Comm Solution
Information used to configure and control video surveillance systems.
